______GENERAL INFORMATION ______editions will contain the required change information in an amendment section at the end of the manual, if required. Please note that this manual is applicable to the following types of upconverters: 1. C, X, Ku or Ka-band upconverters in a single 1U chassis. These upconverters consist of a 70MHz or 140MHz to L-band frequency and gain agile upconverter, plus one L-band to C, X, Ku or Ka L-band block upconverter (BUC). 2. As in 1. but with two or more of L-band to C, X, Ku or Ka BUCs. 3. As in 1. and 2. but with IF selectable between 70MHz and 140MHz. 4. C, X, Ku or Ka-band upconverters with an external BUC, driven by an internal IF to L-band upconverter in a 1U chassis. 5. As in 4. but with external boxes with two or more C, X, Ku or Ka-band BUCs. 6. L-band upconverters with C, X, Ku or Ka-band frequency readout and control.
1.3 SYNOPSIS The U550, U650, U750 and U850 series include synthesised C, X, Ku and Ka-band traffic upconverters specially designed for applications requiring wide frequency coverage and agility, combined with high frequency stability, low phase noise and low amplitude and group delay distortions. The U550 series of upconverters cover part or all of the 5.85GHz to 6.425GHz band in steps of 1kHz, optionally 10kHz, 100kHz or 125kHz. The U650 series of upconverters cover 7.9GHz to 8.4GHz, the U750 all or part of 12.75GHz to 13.25GHz plus 13.75GHz to 14.5GHz, and the U850 all or part of 17.3GHz to 18.4GHz. Table 1.1 at the end of this chapter gives the more common models of these series. Please note that variants of listed models may also be covered by this manual. These upconverters may be configured with external BUC (Block Up Converter). In this case the L-band to C, X, Ku or Ka-band block converter is installed outside the main unit, close to the power amplifier preceding the transmit antenna. The IFL cable carries the L-band signal, the 10MHz locking reference for the BUC (or 50MHz if applicable), DC power and alarm signalling from the BUC to the indoor unit. Some of the upconverters in the U550, U650, U750 and U850 series are configured for dual IF and bandwidth input: 70MHz20MHz, 140MHz20MHz and/or 140MHz40MHz. Selection of desired IF and IF B/W is via front panel menus.

______GENERAL INFORMATION ______
1.4 BRIEF DESCRIPTION The U550, U650, U750 and U850 series include compact synthesised C, X, Ku and Ka-band upconverters, respectively, built in 1U 19" chassis covering all or part of one or more of the following spectrum segments dedicated to satellite uplinking: 5.85GHz to 6.425GHz, 7.9GHz to 8.4GHz, 12.75GHz to 13.25GHz, 13.75GHz to 14.5GHz, 17.3GHz to 18.4GHz. A front panel mounted 16-character alphanumeric display is used to display, in its main operational mode, the conversion gain, in dB, and the output frequency in GHz. The output frequency may be selected through the front panel editing keypad to the right of the front panel. The front panel controls in turn the upconverter synthesised Local Oscillators (LOs), respectively in 1kHz and 5MHz steps. It controls also the conversion gain, the remote control operations and other housekeeping functions. Please check Section 3 for more operational details and front panel operation. These frequency upconverters are a three-stage conversion design where the third stage is a L to SHF (C, X, Ku or Ka-band) Block Up Converter (BUC) with a fixed frequency local oscillator (LO), phase-locked to the unit's high stability OCXO (oven controlled crystal oscillator). This LO is around 1GHz below or above the lower or upper limits of the output band, its exact value depending on the particular model. The input to the BUCs are in the range of 850MHz to 2,150MHz, the precise range depending again on the model. IF-to-L-band conversion is through a two-stage conversion with an internal fixed IF, above the output band, to facilitate image and LO filtering. This IF is 1,650MHz in upconverters covering up to 575MHz, and 2.5GHz in upconverters with coverage wider than 575MHz. In models with an internal IF at 1,650MHz the first LO is around 1,720MHz, 70MHz above the internal IF, and the second LO covers approximately 2,500MHz to 3,100MHz. In upconverters with internal IF at 2.5GHz the first LO is around 2,570MHz, 70MHz above the internal IF, and the second LO covers approximately 3,450MHz to 4,650MHz. In both cases the first LO provides 1kHz steps over a 5MHz range, and the second LO provides the 5MHz coarse steps. This overall frequency plan obviates spectral inversion of signals when upconverted from IF to C, X, Ku or Ka-band: the first and second stages invert signal spectrum while the third stage preserves it. The above frequency plan applies to upconverters with 70MHz IF and with frequency non-inverting IF-to-L-band section. In converters with spectrum inverting IF-to-L-

______GENERAL INFORMATION ______band section the 1,720MHz or 2,570MHz LOs become, respectively, 1,580MHz and 2,430MHz, 70MHz below the internal IF. In converters with 140MHz IF these LOs are 1,790MHz or 2,640MHz for spectrum non-inverting L-band sections, or 1,510MHz and 2,360MHz for spectrum inverting L-band sections. The BUC associated with a particular L-band section is usually such as the overall conversion, from IF to SHF, preserves signal spectrum. Its LO will be therefore below the output band for non-inverting associated L-band sections, and above the output band for inverting L-band sections. These upconverters may be fitted with an option where spectrum inversion may be specifically selectable, in addition to the standard spectrum preserve mode, through front panel menus or the remote interface. In this case the first LO (of the L-band section) will be selectable between being above or below the internal IF, these values being the ones listed above. The 10MHz internal OCXO serves as reference to all three LOs. This OCXO may be phase-locked to an external 10MHz source (optionally 5MHz). The internal BUC may be replaced by an external one mounted in the antenna hub, or in a weather protected antenna cabin, close to the uplink power amplifier. The coaxial cable between the BUC and the main (L-band) unit carries the L-band interface signal, the 10MHz locking reference, DC power from the indoor unit to the external BUC and alarm signalling from the BUC to the indoor unit. Optionally these converters may be continuously tuned over a minimum of ±60kHz by a DC voltage applied through the parallel interface (this is known as the AFC option). This voltage is usually in the ±5V range. Also optionally the gain may be controlled over a 5dB range by a DC voltage applied through the parallel interface (this is known as the ALC option). Parallel and serial interfaces are available through suitable connectors on the rear panel. Parallel interface provides a real-time summary alarm with normally open and normally closed contacts, real-time summary alarms for the internal unit and the associated remote mounted BUC when applicable, with normally open and normally closed contacts, and transmitter mute. And optionally it will provide fine tune of frequency (when AFC option fitted) and control of gain (when ALC fitted). The serial interface provides alarm information, selected frequency and gain, plus control of frequency, conversion gain and transmitter mute. RS232 or RS485 interface standards are available, selectable from the front panel menus. An UXYZ with remote mounted BUC is designated as UXYZR. These upconverters possess an automatic transmitter mute facility with manual override. The output is muted (by circa 95dB at maximum gain or 80dB at minimum

______GENERAL INFORMATION ______gain) whenever there is an alarm condition in the system. Additionally the output may be muted through the RS232/485 remote interface, the back panel 25-way parallel interface connector, or by pressing simultaneously two keys, as labelled, on the front panel. The front panel mute facility may be disabled, if specifically requested by the customer. When the unit is muted the gain display shows “--dB”. These upconverters a ready to implement a simple self-contained 1:1 redundancy scheme. This operates by connecting two upconverters via the 25-way rear panel connector using a suitably wired cable. This nominates one upconverter as master and the other one as slave. The master upconverter mutes the slave, unless it develops a fault. In this case the master output is automatically muted and the slave output is activated/unmuted (unless it is also in fault condition).
1.5 WARRANTY This upconverter is warranted and certified as indicated at the beginning of this manual. For further information contact Novella SatComs Novella SatComs reserves the right to invalidate the warranty if any of the equipment seals are broken or tampered with. All modules and sub-assemblies contained within the equipment are guaranteed by Novella SatComs on a return to factory basis.

______INSTALLATION ______
2.3.2 Power cable Mains input is through a standard IEC/CEE22, 3-pin moulded plug and connector block. The cable is connected to the equipment via a LINE input socket containing integral mains voltage selection, fuses, interference suppression filter and power ON/OFF switch.
2.4 OPERATING ENVIRONMENT No forced air cooling is required if the equipment is operated at temperatures between 0°C and 50°C. When mounting the equipment, choose a location that provides at least 50mm around the rear and both sides of the equipment. Normal air circulation will keep temperature in the unit within component specifications.
2.5 INSTALLATION This frequency converter is designed to be mounted in a standard 19" rack system with support brackets at each side. Figure 1.2 provides information necessary for electrical connections to the equipment. (a) Signal input: The IF input signal should be fed to the BNC back panel connector labelled "IF INPUT". This is a 50 BNC female connector. (b) Signal output: The cable carrying the C, X, Ku or Ka-band output signal should be connected to the back panel connector labelled "RF OUTPUT". This is an N-type female connector, impedance 50. In units with external BUC the connector labelled "RF OUTPUT" is linked by the IFL cable to the BUC's input connector.. This cable carries the L-band interface signal, the 10MHz locking reference, DC power for the BUC and alarm signalling from the BUC to the indoor unit. (c) Parallel interface: This interface is available through the back panel 25- way female D-type connector, labelled "INTERFACE". Refer to Table 2.1 for a list of functions of all the pins of this connector. For more information about operation of this interface refer to Section 3. (d) Serial interface: This interface is available through the back panel 9-way female D-type connector, labelled "REMOTE". Novella equipment is usually fitted with a serial remote interface, RS232 or RS485 4-wire selectable from the front panel. Table 2.2-a provides a list of functions of the pins of this connector. Other RS485/422 interfaces may be supplied by request, namely RS485 2- wire (CSL compatible), Miteq 4-wire or SAbus 4-wire. Tables 2.2-b, 2-2c

______INSTALLATION ______
2.2-d provide other wiring schedules for the 9-way connector. Table 3.1 gives details of the options and configuration of the receiver(s) supplied with this manual. (e) Address: Address, baud rate and other configuration parameters are set through the front panel. (f) External reference input: An external locking signal, usually 10MHz, optionally 5MHz, 0dBm nominal, may be fed to the BNC connector on the back labelled "EXT REF INPUT". (g) Internal reference: A sample of the internal OCXO, at 10MHz, is available from the BNC connector on the back panel labelled "INT REF OUTPUT". Optionally this sample may be available at 5MHz. (h) Power input: Connect the power cord supplied to the power input socket. (i) Earth bonding: An earth bonding conductor should be connected between the rack and the terminal located to the right-hand side of the power input socket.
2.6 UPCONVERTERS WITH EXTERNAL BUC If the upconverter is supplied with an external BUC, this unit should be installed in the same cabin or enclosure where the power amplifier is located to minimise RF losses. The BUC's output N-type connector must be connected by a suitably rated coaxial cable to the HPA's input. Connect one end of the IFL cable to the N-type input connector of the BUC and the other end to the "RF OUTPUT" connector on the back panel of the indoor unit, or to the corresponding connector on an associated rack patch panel. The external BUC may take DC power through the IFL cable or from a "local" DC source in the antenna hub or cabin. Consult Table 3.1 to check which option applies to the upconverter(s) supplied with this Manual.
WARNING: Do not fit attenuators or splitters between the BUC input and the indoor master unit input, as DC and 10MHz is supplied through the same cable. Attenuators or splitters may be used if a DC path is provided for the DC supply and the insertion loss at 10MHz does not prevent the remote BUC from locking.
Special care must be taken with the overall upconversion gain to avoid saturation in

3.1 INTRODUCTION This section provides full operating instructions for the U550, U650, U750 and U850 series of C, X, Ku and Ka-band upconverters. Front and rear panel controls, connectors and indicators are identified and described in Figures 1.1 and 1.2.
3.2 FUNCTIONAL CHECKS The functional tests and adjustments described below should be performed upon commissioning of the receiver, or when its configuration in a system is being changed.
3.2.1 Power-up functional checks (a) Check that correctly rated mains power input fuses are fitted (T1A). (b) Check that the mains input socket integral voltage selector (Figure 1.2) is correctly set (to 115V or 230V AC). Apply mains to this socket and switch the equipment on. (c) Check that the status of the following LEDs is as described in the table:
ITEM CHECKED STATUS ON LINE LED lit REMOTE LED unlit ALARM LED becomes unlit in less than 90 seconds LOCKED LED becomes lit in less than 90 seconds EXT REF LED unlit
3.2.2 Operator functional checks (a) Supply a signal of 70MHz, -30dBm at the IF input. Monitor the RF output signal with a spectrum analyser with the following settings: centre frequency 6.2GHz, 8.2GHz, 13GHz, 14GHz, 17.5GHz or any frequency in the middle of

______OPERATION ______
the applicable band, span 10MHz, reference level 0dBm. Using the front panel menus select the same value frequency. Ensure that the unit is not muted. Verify that a signal is visible on the analyser. (b) Using the front panel menus adjust the gain to 0dB, or attenuation to 30dB, and verify that the output level is around -30dBm (±2dB). Adjust now the gain to 30dB, or attenuation to 0dB, and observe the display going up to circa 0dBm (±2dB). Mute the unit by pressing simultaneously the two labelled keys on the front panel. If unit mute is not available from the front panel (check Table 3.1 for options and configuration) short pins 4 and 5 of the 25-way rear panel connector. Verify that the signal displayed on the analyser “disappears” into the noise floor. (c) Repeat the above tests at frequencies close to the edges of output coverage, in accordance with model in use. Change the centre frequency setting of the analyser accordingly and verify that an output signal with level 0dBm (±2dB) is visible on full gain (when front panel displays gain of 30dB, or attenuation of 0dB), or -30dBm (±2dB) (when front panel displays gain of 0dB, or attenuation of 30dB). (d) Supply a 10MHz (±50Hz) signal, 0dBm, to the back panel connector labelled "EXT REF INPUT". Verify that the front panel LED labelled "EX. REF." becomes illuminated. The LED labelled "ALARM" may become illuminated for a short period but should extinguish in less than 90 seconds.
3.3 FRONT PANEL OPERATION 3.3.1 Introduction The front panel is the centre of the user interface for this converter. The table in Figure 3.1, next page, provides a summary, in matrix form, of all menu selections. The top left hand side box is the operational display: the upconverter powers up in that menu, which will display the last used gain (attenuation) and frequency values. The “Up” and “Down” keys may be used to move “vertically” between the different menus of the first column. Pressing the “Right” key will move the menu selection to the top of second column. Likewise, pressing again the “Right” key will move the menu selection to the top of the third column. Pressing again the “Right” key moves again the menu selection to the top of the next menu column to the right. When the last column is selected pressing again the “Right” key moves the selection to the top of the first column.

______OPERATION ______
Please note: Pressing the “Left” key does not move menu selection to the right. Menu selection need not bet at the top row to move to the next menu column. Most menu cells in the previous table allow selection or editing of a particular parameter. This is not the case for the top left hand cell, which is also the operational display modes, and the cells in the “Information” column. Some or all cells in the “Options” column may not allow any selection, depending on upconverter configuration and facilities. Selection and/or editing of the different cells is covered by the operational instructions in the next subsections.
3.3.2 Frequency selection The operational frequency is indicated by the LCD display, when in the operational display mode. In this mode, conversion gain, or attenuation, and frequency, are displayed as in the sample below: 10dB 18.123456
Press the Down key once. The following display appears: Freq 18.123456GHz
Press now the EDIT/Left key: a cursor will appear under the units of kHz digit: Freq 18.123456GHz
Pressing the Left or Right keys moves the cursor under the various digits, from tens of GHz to units of kHz. Pressing the Up / Down keys increases / decreases the digit above the cursor. Once the required frequency is set, press the ENTER key to set the new frequency.
NOTE: When the operational frequency is changed the converter may temporarily lose lock (e.g., one or more synthesisers may lose lock). This is indicated by the LOCKED LED becoming extinguished and the ALARM LED illuminated. This occurrence and its duration is a function of the frequency step applied to the synthesisers. This out-of-lock situation should always last less than 1 second. The upconverter is temporarily muted while a frequency change is being activated.
Pressing the Up key once will bring the display to one of its main operational mode. The front panel internal circuitry creates a 29-bit digital code, corresponding to the representation of each digit of the selected frequency in 4-digit BCD code (the tens of GHz only uses one bit). This 29-bit bus is used to control both synthesised LOs of the IF-to-L-band section. The second synthesiser provides coarse frequency selection in

______OPERATION ______
5MHz steps, while the second provides fine selection in 1kHz steps. Selection of an operational frequency value means that when a 70MHz (140MHz if applicable) is applied at the input connector, a signal with the selected frequency (GHz) appears at the output connector.
3.3.3 Gain / attenuation setting These converters may either use conversion gain or conversion attenuation as the other operational parameter, in addition to frequency, in GHz. If conversion gain is used this is usually between 0dB and 30dB (3dB), with other ranges possible (for example 10dB to 40dB). Attenuation, when used, is always taken relative to maximum output signal. In the more common case of 0dB to 30dB gain, 0dB attenuation is equivalent to 30dB gain (maximum output), while 30dB attenuation is equivalent to 0dB gain (minimum output). This section describes the procedure to adjust the conversion gain or attenuation. While within the main operational display mode press the Down key twice until the following (specimen) display appears: Set Gain 10.00dB
Press EDIT/Left key and the following display will appear: Coarse 10.00dB
Press repeatedly the EDIT/Left key or the Right key and the display will cycle between the following three screens: Coarse 10.00dB Medium 10.00dB Fine 10.00dB
Pressing the Up key will increase the above reading, while pressing the Down key will decrease it. Speed of adjustment will be fast, medium or slow, respectively, within the Coarse, Medium or Fine displays. Once the required level is obtained press the ENTER key to confirm the choice of level. Assuming that the display value has been changed to 20.00dB (specimen value), pressing ENTER will enable the new gain setting and revert the display to: Set Gain 20.00dB

______OPERATION ______
Pressing the Up key twice will bring the display to the operational mode. If the converter uses attenuation as an operational parameter, attenuation adjustment is identical to gain adjustment, with the only difference that the attenuation adjustment display is as follows (sample display): Set Atten 20.00dB
For compatibility with other manufacturers gain adjustment may be set to 0.2dB increments, as opposed to 0.01dB. Please note that, although selection granularity of gain setting is 0.01dB, setting accuracy is only guaranteed to be 0.1dB. To select 0.2dB gain setting move to the second menu column and press the Down key three times. The following display appears: Gain Res 0.01dB
Pressing the EDIT/Left key repeatedly will toggle the display between the above and the following display: Gain Res 0.2dB
Pressing the ENTER key selects the desired gain selection resolution. When 0.2dB gain resolution is selected the Fine, Medium and Coarse gain adjustment selections are not available. Instead the gain setting displays are as follows: Set Gain 10.00dB and pressing EDIT/Left leads to: Set Gain 10.00dB upon which pressing the Up / Down keys will increase / decrease the gain in 0.2dB increments / decrements. The same applies when attenuation is the operational parameter whereby the above display will be: Set Atten 20.00dB
3.3.4 ALC option These converters may optionally be fitted with an ALC facility. In this case the
Novella SatComs ______
90-6031, Issue 4 3-6 May 2008 C, X, Ku & Ka-band upconverters, operation and maintenance manual
______OPERATION ______conversion gain may be adjusted within ±5dB by ±5V DC applied through the back panel connector labelled "INTERFACE". This option is used in accurate uplink power control systems, such as one where the measured downlink beacon level is used as an indication of an uplink fade. Or it may be used in ALC loops where a sample of an SSPA/HPA output is used to drive a power head, which in turn will generate a DC control voltage which, after appropriate conditioning, will maintains the transmitted power within very narrow limits, usually ±0.1dB. If this ALC option is fitted, gain adjustment through the front panel or remote interface has a range of only ±10dB.
3.3.5 External reference The internal OCXO may be phase locked to an external 10MHz (optionally 5MHz) reference. This external reference is supplied through a back panel 50 BNC connector labelled "EXT REF INPUT". Its level is nominally 0dBm. Phase locking will take place with external reference signal levels between -5dBm and +20dBm approximately. Optionally the External Reference input circuitry may be configured for TTL or other similar drivers. In this case the input impedance is 1k and the input reference signal should have a peak-to-peak amplitude between 50mV and 5V.
3.3.6 Reference output The internal OCXO reference signal is available through the back panel BNC connector labelled "INT REF OUTPUT". This is usually a square wave of 1V peak- to-peak, driven from a 50 impedance, with frequency of 10MHz, optionally 5MHz. This reference output may be used as a locking reference for other equipment, or as a test point during fine trimming of the internal OCXO reference. Other output levels are optionally available.
3.3.7 Internal OCXO frequency trimming The internal reference frequency is factory adjusted to precisely 10MHz using an off- air standard. This frequency changes very slowly due to crystal ageing. For this reason this upconverter is supplied with a fine frequency trimming facility. A small potentiometer, mounted on the master PCB, is accessible through a small hole on the back panel labelled "INT REF ADJUST", and may be used to electrically adjust the OCXO frequency. Before proceeding with the frequency trimming the equipment should be allowed to
Novella SatComs ______
90-6031, Issue 4 3-7 May 2008 C, X, Ku & Ka-band upconverters, operation and maintenance manual
______OPERATION ______warm up (from a cold start) for at least two hours. This frequency trimming should be performed with the aid of a high accuracy frequency counter, with resolution of 1Hz or better, preferably locked to an off-air or atomic standard. The frequency counter should be connected to the BNC socket labelled "INT REF OUTPUT". Adjust the potentiometer until the frequency counter reads exactly 10.000 000MHz (or if applicable 5.000 000MHz). This operation is not necessary if the upconverter is locked to a station standard (off- air, rubidium, caesium, etc.). If the upconverter is not locked to an external reference this frequency trimming should be performed once a year for best frequency accuracy.
3.3.8 AFC or analogue tuning option When this option is fitted the frequency of the output signal may be continuously adjusted over a minimum of ±60kHz from its nominal selected value. This is achieved by applying a DC voltage through the 25-way D-type connector labelled "INTERFACE", located on the unit's back panel. This voltage is usually in the range ±5V, but other values are optionally available, namely +1V to +7V (to interface to third party equipment such as SCPC cards). The tuning voltage is applied between pins 11 and 12 of this connector. These pins connect to the high impedance inputs of a differential amplifier.
NOTE: None of these pins should be grounded on the upconverter side, even when the driver is single-ended. In this case the 0V reference conductor must be grounded only on the driver side. Pin 13 of the D-type "INTERFACE" connector is a shielded ground supplied to connect the cable shield, if available. It should not carry any current and must not connected to either pin 11 or pin 12 on the upconverter side. Frequency steering operates as follows: An increase of differential voltage between pin 12 and pin 11 increases the frequency of the output signal for fixed 70MHz frequency input signal. A decrease of differential voltage decreases the frequency of the output signal for fixed 70MHz frequency input signal. Frequency steering with the opposite characteristic may be optionally supplied. The control voltage-to-frequency offset characteristic is monotonic and has a linearity better than ±10%.
3.3.9 Alarms The summary alarm monitors the lock status of the converter’s PLLs used to generate
Novella SatComs ______

______OPERATION ______the three LO signals. When an alarm condition occurs a real time summary alarm output is provided via isolated dry relay contacts. These are available through the back panel 25-way D-type connector labelled "INTERFACE" (Figure 1.2). Refer to Table 2.1 for details of the "INTERFACE" 25-way D-type connector schedule and alarm contact logic. If a summary alarm is raised that probably means that one or more of the synthesisers' PLLs are out of lock or is malfunctioning. A malfunction or fault of the power supply will also raise a summary alarm. The normally open contacts will default to open when there is an out-of-lock situation or a power failure. This upconverter has a second set of relay alarms, one for the L-band, frequency agile, card, the other for the BUC (L-to-SHF block converter). The second of these alarms is only active when the upconverter is fitted with an external BUC. the L-band or master card possesses a sensing circuit will detect under-current, over-current and LO out of lock conditions. Any of these will trigger a BUC alarm. Under-current is usually generated but a disconnected BUC, over-current usually by an L-band cable short. A BUC LO synthesiser out of lock is indicated by a 1kHz pulse. When the upconverter possesses an external BUC, a BUC alarm, or indeed a BUC not connected condition, will activate a summary alarm, as well as the BUC relay alarm, indicated also by the front panel ALARM LED. The front panel LOCK LED indicates in this case only a lock condition for the master card, and it will continue illuminated even if the remote BUC is out of lock or removed. If the BUC is however fitted internally, a BUC alarm condition will extinguish the LOCK LED will illuminating the ALARM LED.
3.3.10 RS485/RS232 interface 3.3.10.1 Introduction The converter RS485/RS232 remote interface allows serial connection to a controller or computer (host) with a compatible interface. Connection to host is through the back panel 9-way D-type female connector labelled "REMOTE". Tables 2.2 give various possible connection schedules. If Novella’s own standard is used the interface driver may be selected as RS232 or RS485 4-wire. The pin allocation is such as the equipment can be connected, when in RS232 mode, to a PC with a 9-way connector serial interface via a 9-way male to female cable, with both ends connected on a one- to-one basis. The host may perform the following functions: (i) Selection of output frequency; (ii) Selection of upconversion gain or attenuation;
Novella SatComs ______

______OPERATION ______
(iii) Output mute/unmute; (iv) Programming of memory locations; (v) Selection of spectrum invert/preserve (if applicable); (vi) Selection of local/remote mode; (vii) Output frequency status; (viii) Conversion gain / attenuation status; (ix) Converter alarm status; (x) Output mute status; (xi) Reading of pre-programmed memory locations; (xii) Spectrum invert/preserve status (if applicable). The first to sixth functions are commands from host to converter, which is toggled to REMOTE mode by the first command. The upconverter may be toggled back to LOCAL mode by the host. Converters required to have 100% compatibility with other manufacturers’ will have options within the front panel operation menus allowing selection of REMOTE / LOCAL modes by a local operator, instead of the host controller. In this case the converter must be in local mode before it will accept any command to update its frequency or gain/attenuation. Check Table 3.1 for configuration and options of converter(s) supplied with this manual. The other six functions involve sending data from the upconverter to host, usually at its direct or indirect request. When the upconverter is in REMOTE mode the front panel LED labelled "REMOTE" will be illuminated.
3.3.10.2 Interface configuration The U850 serial remote interface is configured through some front panel menus, used to set the unit's address and baud rate. Depending on version of firmware and options and configuration of an upconverter this configuration is done via the “Display Setup” or the “Communications” menu column. Press the Right key successively until the “Display Setup” or “Communications” label, as may be applicable, appears. If the interface setup is through the “Display Setup” menu column press the Down key 4 times and the following display appears: Comms RS485
Novella SatComs ______

______OPERATION ______
Pressing successively the ENTER key this display toggles between the following three: Comms RS485 Comms RS232 Comms off
If a protocol other than Novella’s is used, with a different 9-way connector schedule, selection of RS232 is not possible: that option will not appear on display. Press the Down key again will bring the display to on of the following lines: Baud 9600 Baud 4800 Baud 2400 Baud 1200 Baud 300
To change the baud rate press successively the EDIT/Left key: the displayed baud rate cycles from 300 to 9600, back again to 300. When the desired baud rate has been selected press the ENTER key.
Press the Down key once again and the following display will appear: Address A where A may be a set of ASCII characters. These characters are in the range. 30H to 4FH, or ASCII symbols "0" to "O". To modify the address press the EDIT key once, the display turning to Address A ?
Press the Up or Down keys to respectively increase or decrease the displayed address around its range of allowable values. Press ENTER to select the displayed value as the new address.
Valid addresses are ASCII characters 30H to 4FH, or ASCII symbols "0" to "O". Table 3.1 lists all valid addresses and their associated ASCII hexadecimal codes. This is applicable to Novella’s own protocol. Other protocols may have a different set of addresses.
Novella SatComs ______

______OPERATION ______
It is recommended that the unit be reset (by switching it off) when the address is changed. If the interface setup is through the “Communications” menu column press the Down key once and the following display appears: Comms Local
This is only possible if the unit is in Local mode. Units with this protocol may be toggled between Local and Remote modes by using the above menu option. Pressing EDIT/Left key sets the unit to Remote mode.
Press simultaneously ESC and EDIT keys to revert to Local mode.
From this point setting up the remote interface is similar to the one described before, within the “Display Setup” menu column. Table 3.1 lists all valid addresses and their associated ASCII codes.
3.3.10.3 Serial interface protocol 3.3.10.3.1 Communication and message format Communication between receiver and host is via a sequence of ASCII characters (all in the range of printable characters). These represent commands from host to receiver, or data from receiver to host. Valid character codes are in the range 21H to 7AH. Each character has ten bits as follows: 1 start bit, 8 data bits, 1 stop bit. No parity bit is used. SAbus compliant messages are as follows: 1 start bit, 7 data bits, even parity, 1 stop bit. A message (from host to receiver, or vice-versa) has the following format:
Header + Address + Message + + Message parameters + Trailer + Checksum
Novella SatComs ______

Message parameters are not always applicable. The checksum (1 byte) is sent immediately after the trailer. The following list provides the general format of the various parts of a message.
Parameter ASCII symbol ASCII code, HEX Header { 7B Address "0" to "O" 30 to 4F Message and parameters See list Trailer } 7D Checksum ASCII character calculated in accordance with rules below
3.3.10.3.2 Checksum calculation Checksum calculation is done using the ASCII values of the characters between the Header and the Trailer, inclusive, in accordance with the following formula:
Checksum = MOD[(ASCII value - 32), 95] + 32
As an example, the command {AF06500000}, meaning change frequency of unit with address A to 17.500000GHz, will have a checksum of "/" = ASCII(47):
Character ASCII - 32 = { 123 91 A 65 33 F 70 38 1 49 17 7 66 34 5 53 21 0 48 16 0 48 16 0 48 16 0 48 16

ASCII[MOD(408 , 95) + 32] = ASCII(60) = "<" The full message, including checksum, will be:
{AF17500000}<
A host should have the capability (like a subroutine in its controlling software) to calculate the checksum value of any command. This checksum value is an integral part of the command, and is added after the trailer, "}".
3.3.10.3.3 Control frequency, gain and mute status This is a command sent by host to upconverter to change output frequency, upconversion gain and mute status. The syntax of this command is as follows: Header {
Address ASCII code from 30H to 4FH Frequency F followed by 8 digits representing frequency, from left to right, tens of GHz to units of kHz
Gain 3-digit hexadecimal from 000H
to FFFH, coded as per Table 3.2 Mute status "M" for muted output, "U" for enabled output Trailer } Checksum one ASCII character as calculated in 3.3.10.3.2. EXAMPLE: {AF17500000200U}7 is the command which should be sent to change the frequency of the upconverter with address "A" to 17.500000GHz,
the gain to 200H (18dB), and to enable the output. Leading and trailing zeros must be included to fill the fields from tens of GHz to units of kHz, plus the three fields for gain.
3.3.10.3.4 Remote enable The upconverter is automatically set to REMOTE mode at the first command to
Novella SatComs ______

______OPERATION ______change frequency and/or gain. There is usually no other way to achieve this, if Novella’s protocol is used. Converters with protocols 100% compatible with other manufacturers’ converters usually have an “extended” command to set the unit to REMOTE mode. However, the “compatible” way to toggle the unit to REMOTE mode is via a submenu of the Communications menu column. Consult Appendix A for more details
3.3.10.3.5 Local enable This command reverts the upconverter to "LOCAL" mode, which means that the front panel will have control over the output frequency and gain selection. The syntax is as follows: Header {
Address ASCII code from 30H to 4FH Command L Trailer } Checksum one ASCII character as calculated in 3.3.10.3.2. EXAMPLE: {AL}g is the command to revert the upconverter with address "A" to LOCAL mode. Converters using Novella’s own protocol may be switched back to LOCAL mode, once in REMOTE mode, only via this command with through a unit’s hard reset (switch off/on). Converters with protocols 100% compatible with other manufacturers’ converters will have a similar command: check Appendix A for details. In addition to this “extended” way of toggling back to LOCAL mode, this may be achieved, in units with such protocol, by pressing simultaneously ESC and EDIT keys. Toggling back to REMOTE mode is via a submenu of the Communications menu column.
3.3.10.3.6 Status request This is a request for information, rather than a command, from host to upconverter. It does not affect upconverter status. Instead it prompts the upconverter to send back to host its present status. The syntax is as follows: Header {
Address ASCII code from 30H to 4FH

EXAMPLE: {AS}n is the command to request upconverter with address "A" to send its present status. Converters with other protocols have similar commands, with different syntax. Check Appendix A for details.
3.3.10.3.7 Status message All commands or requests from host to upconverter invoke a response, the Status Message, which indicates the status of various upconverter parameters. The syntax is as follows: Header {
Address ASCII code from 30H to 4FH Control status L, for LOCAL, or R, for REMOTE Frequency F followed by 8 digits, representing output frequency from tens of GHz to kHz
Upconversion gain 3 digits in the range 000H to FFFH Summary alarm status "*" for alarm; "-" for no alarm BUC alarm status "*" for alarm; "-" for no alarm
(this field applies only to units
with remote mounted BUC) Lock reference "I" for internal; "E" for ext. Mute status "M" for muted, "U" for enabled output Trailer } Checksum one ASCII character as calculated in 3.3.10.3.2.
EXAMPLE: {ARF17500000200--IU}I means that the upconverter with address "A" ("11" on the back panel switches) is in REMOTE mode, its selected output frequency is 17.500000GHz, the upconversion gain is 18dB ( 200H), there is no alarm condition (unit with internal BUC) and the internal reference is being used.

3.3.10.3.8 Upconversion gain coding
The upconverter gain is represented by a 3-digit hexadecimal code, from 000H to
FFFH, corresponding, respectively to 0dB and 30dB gain. Conversion from the hexadecimal code to dB in the range 0 to 30 is linear. The gain value so obtained should always be rounded to the nearest tenth of dB. If gain range is other than 0dB to 30dB, conversion is still linear. For compatibility with older units the upconversion gain, from 0dB to 30dB, may be coded according to the look-up table in Table 3.2. This look-up table is given in 0.5dB steps. The resolution of 0.1dB is achieved by interpolating linearly between the values of the look-up table. The control software should be coded to calculate the hexadecimal codes in 0.1dB steps, and to convert hexadecimal codes read from the gain control subsystem to gain in 0.1dB steps. The full 12-bit range of 000H to FFFH covers marginally more than the 0dB to 30dB gain range. Table 3.2 gives also the approximate gains for these end codes. This gain coding option is only supplied by special order. Converters 100% compatible with other suppliers’ converters will have a different gain coding. Consult Appendix A for details.
3.3.11 Transmitter mute The output of the upconverter may be muted (by a minimum of 90dB at full gain and 80dB at minimum gain) by grounding pin 4 of the back panel 25-way D-type connector labelled "INTERFACE". It may be also muted by simultaneously pressing the ESC and ENTER front panel keys (they are jointly labelled MUTE). This front panel mute facility may be disabled, if specifically requested. Consult Table 3.1 for details of configuration and options of the unit(s) supplied with this manual. When the output is muted the gain indication on the front panel display reads as follow (sample display): --dB 18.123456
Output mute may be also achieved through the serial remote interface. Any alarm will automatically mute the output.

APPENDIX A
UPCONVERTER COMPATIBLE REMOTE INTERFACE PROTOCOL
A.1 IMPORTANT NOTE This appendix describes the software protocol used in units with Miteq compatible protocol. While having taken and continuing to take all reasonable steps to ensure that this protocol is 100% backwards compatible with MITEQ upconverters protocol, Novella SatComs is in no position to guarantee that any particular control software will work satisfactorily with this protocol. In case of difficulty contact Novella SatComs for help and/or information on this subject.
A.2 LOCAL/REMOTE SELECTION The upconverter is in Local mode when all its parameters can be set from the front panel: frequency, gain and mute status. The REMOTE LED will be off in this case. The unit is in Remote mode if all these parameters are changeable only via the RS232/485 remote interface. If the unit is in Remote mode its parameters are not accessible via the front panel. Local/Remote selection is via a front panel menu, in the second column of the menu matrix. If change of Local/Remote status is required move to the second column of the menu (Display setup). Press the Down key repeatedly until Local (or Remote) appears. Pressing EDIT key will toggle the unit between Local and Remote. In addition to this selection mode the unit accepts two extra, “non-compatible” command codes: X, to set the unit to remote mode; Y, to set the unit to local mode.
A.3 RS232/485 PROTOCOL
A.3.1 Message structure All messages, to and from the unit, are multi-byte sequences beginning with a header and finishing with a trailer followed by a checksum. The transmitted bytes are all ASCII printable characters in the range 20H to 7DH (“CR” or “carriage return” to “}”). Data transmission format is a 10 bit sequence consisting of 1 Start, 7 Data, 1 Parity and 1 Stop bit. The Parity bit is set to even. All characters, including checksum, are checked for parity. If any character in the message has a parity, framing or overrun error, the entire message is ignored and no reply sent back. All commands sent to the unit by the controller are normally acknowledged with a
Novella SatComs ______
90-6031, Issue 4 A-2 May 2008 C, X, Ku & Ka-band upconverters, operation and maintenance manual
______APPENDIX A ______reply. Before sending the reply the unit checks for no activity on the communication bus for a period of at least one character time. If the bus is active the reply is cancelled. This allows a controller to rapidly update a number of devices without having to wait for a response. When using this method for updating devices, the following restrictions will apply: Minimum command update period is 100 milliseconds, Multiple commands may not be sent without waiting for a response from each command. The unit continually monitors the bus and will accept all commands addressed to it even when in Local mode. When in Local mode, receipt of any commands other than Status All, Status Faults, Set Remote mode or Set Local mode will be ignored and the unit will respond with an error code. The command code X, Set Remote mode, may be used to set the unit to Remote mode from the controller. Likewise, the command code Y, Set Local mode, may be used to set the unit to Local mode from the controller. These two “extension” commands.
A.3.2 Message format A.3.2.1 Introduction The general message format is as follows: Header + Device address + Command/error code + + Parameters + Trailer + Checksum The reply time from Command to acknowledge is 100ms maximum. Since all bytes are ASCII printable characters, a compatible terminal may be used to control the unit, or monitor traffic on the bus.
A.3.2.2 Header byte
The Header byte is 7BH, ASCII character “{“.
A.3.2.3 Device address byte
The compatible device address range is 40H to 5FH, or “@” to “_”, 32 addresses in total. Novella’s extended device address range goes from 30H to 4FH, or “0” to “O”. For reasons of full compatibility addresses from 30H to 3FH should be avoided.

______APPENDIX A ______
A.3.2.4 Command and error codes The following is a list of all command codes implemented in this unit. The last two, X, or Set Remote mode, and Y, or Set Local mode, are extensions to the compatible command set.
A.3.2.5 Parameter bytes Parameters are numeric characters, such as frequency, gain or attenuation numerical figures, which are sent MSD first, LSD last. Non-numeric parameters, such as decimal points or thousands separators (commas) and parameter values beyond the unit’s range are rejected, causing the unit to respond with error code “b”.
A.3.2.6 Trailer byte Trailer byte is 7DH, ASCII character “}”.
A.3.2.7 Checksum byte The checksum byte is the sum modulo 95 of all message characters beginning with the header byte up to and including the trailer byte. In calculating this checksum the value 32 is subtracted from each character value before taking the modulo 95 sum. The value 32 is then added to the final sum to obtain the checksum value. This algorithm produces checksum characters all within the printable range, from ASCII(32) to ASCII(126), “CR” to “~”. All calculations are done in decimal, all ASCII values are also in decimal. The following is a summary of the algorithm required to calculate the checksum. Subtract 32 from each character ASCII decimal value. Add all the above values for all the message characters, including message header and trailer. Take modulo 95 from the above sum. Add 32 to the previous result. The checksum is the ASCII character corresponding to this result.
A.3.3 Compatible command codes The various command codes are described next in more detail.

______APPENDIX A ______
A.3.3.1 Frequency command, F The frequency command requires a seven or eight digit (decimal) parameter which sets the unit’s operating frequency in kHz. Frequencies below 10GHz are defined by seven digits, above 10GHz by eight digits. Upon reception of this command the unit is set to the specified frequency and unmuted. Examples: {@F18123456}c {@F18123456}c In these and all following examples @ represents a generic unit address, c represents the checksum as calculated in accordance with A.2.2.7 (c is not the actual checksum character, just a generic representation). The numeric parameter after F consists of seven digits for frequencies below 10GHz. The upconverters accept however eight parameters with a leading zero: {@F18123456}c The unit replies with F. Example: {@F}c The unit must be in Remote mode or the unit will not change frequency and will reply with an error message, c = “unit in local mode”. Example: {@a}c
A.3.3.2 Mute command, M The mute command mutes the upconverter output. The unit may then be unmuted by a frequency or an unmute command. Example: {@M}c The unit will reply with a similar string: {@M}c The unit must be in Remote mode or the mute command will have no effect and an error message (c = “unit in local mode”) will be sent: {@a}c
A.3.3.3 Unmute command, U The unmute command activates the upconverter output, unless a fault exists (hardware muting overrides software unmuting). Example:

______APPENDIX A ______
{@U}c The unit will reply with a similar string: {@U}c The unit must be in Remote mode or the unmute command will have no effect and an error message (c = “unit in local mode”) will be sent: {@a}c
A.3.3.4 Attenuation command, T The attenuation command requires a three digit parameter (numeric characters from 0 to 9) defining the attenuation of the upconverter output signal in 0.2dB steps. The unit’s attenuation is immediately set but the mute status is not affected (if muted, the unit will remain muted). Example: {@T124}c The least significant digit in the attenuation value can only be 0, 2, 4, 6 or 8. Usual upper and lower limits for this parameter are 300 and 000, respectively 30.0dB and 0.0dB of attenuation (decimal point is omitted in the command) The unit will reply: {@T}c The unit must be in Remote mode or the attenuation command will have no effect and an error message (c = “unit in local mode”) will be sent: {@c}c
A.3.3.4.1 Attenuation increment command, TINC This command is similar to the previous one, except that the attenuation is incremented by 0.2dB: {@TINC}c Replies as before.
A.3.3.4.2 Attenuation decrement command, TDEC This command is similar to the previous one, except that the attenuation is decremented by 0.2dB: {@TDEC}c

Replies as before.
A.3.3.5 Combined frequency and attenuation command, C This command sets frequency and attenuation simultaneously. Examples: {@CF18123456T124}c {@CF6123456T124}c The unit replies with C. Example: {@C}c The unit must be in Remote mode or the unit will not change frequency or gain and will reply with an error message, c = “unit in local mode”. Example: {@c}c
A.3.3.6 Status request command, A This command requests that the unit send back frequency, attenuation, remote/local status, IF selection, mute status and alarm status. Example: {@A}c The reply from the unit is as follows: {@AF18123456T124L0I0M0?000000}c Some fields are provided for compatibility with other manufacturers’ equipment. L0 field is a local/remote indicator: L0=Local mode, L1=Remote mode. I0 is a field provided for compatibility, and it means IF=70MHz. In units with IF=140MHz this field is I1. M0 field is for the mute status: M0 = unmuted, M1 = muted. The string ?000000 is for alarm status, and it has this format for compatibility. Novella’s upconverters have only a summary alarm (the first field in that string), or two separate ones in upconverters with external BUCs (in this case the two first alarm fields would be active). An alarm field indicates the activation of the respective alarm when its parameter is 1. Examples of replies with alarm(s) activated. {@AF18123456T124L0I0M0?100000}c The frequency and attenuation fields have a format similar to the equivalent commands.

The unit will reply with, respectively {@J0}c {@J1}c if the unit is in remote mode. If the unit is in local mode it will reply with the error message {@c}c where “c” = Unit in local mode.
A.3.4.4 Status reply in units with spectrum invert selection Units with the spectrum invert facility enabled will reply to the Status Request Command, A, with the following message: {@AF18123456T124L0I0M0J0?000000}c when spectrum preserve mode is on, or {@AF18123456T124L0I0M0J1?000000}c when spectrum invert mode is on.
A.3.4.5 Change IF and IF bandwidth command Models with selectable IF and IF bandwidth may be set to 70 20MHz, 140 20MHz or 140 40MHz. This is done via the front panel menus when the unit is in local mode, but it may be done via the remote interface when the unit is in remote mode The command format to set or change the IF is: {@Ix}c where x may be 0, 1 or 2 as follows: {@I0}c 70 20MHz {@I1}c 140 20MHz {@I2}c 140 40MHz The unit will reply with the following status reply message: {@I}c command accepted or the following error messages, as applicable: {@b}c invalid command {@c}c unit in local mode, cannot accept command

ETHERNET INTERFACE Mk I Terminal-Host Setup and Configuration
B.1 INTRODUCTION Some equipments may be supplied with an Ethernet interface option. The present version of this interface is based on Digi Connect ME Ethernet module which provides a virtual serial interface/connection between a piece of equipment and a host computer connected through a LAN. The controlled unit is hence provided with an RJ45 Ethernet connector allowing it to be directly linked to a LAN port. A host computer in the same network then runs a piece of software (supplied) which emulates a serial COM port. The host may then control the piece of equipment using existing serial interface control and monitoring software. The software protocol described in Appendix A is still applicable. Each controlling host in the LAN must be configured as an individual logical COM port. If two or more pieces of equipment are connected to the same LAN they should be configured with different addresses to allow the host to address tem separately. The serial control data generated by the equipment is converted to TCP/IP packets, transported through the Ethernet network and then converted back to serial data at the host. The same happens between host and equipment. The TCP/IP transportation is transparent to users. A host which is to control a piece of equipment connected to the same LAN must have the Digi Realport software installed. The software and drivers for various platforms are provided in a CD-Rom supplied with the equipment or can be found on Digi support website: www.digi.com/support.
B.2 INITIAL SETUP 1. Run Digi Realport setup wizard. This is done by running “setup.exe” in folder for the operating system of the host. Administrator rights are required for installation. 2. The Welcome page below appears, click “Next”. 3. The wizard will detect any powered up Digi terminals/devices in the network. A list of terminals with their IP and MAC addresses will be displayed. Digi Connect ME module will take about 1 minute to start-up. Pressing the “refresh” button will force the wizard to search again.

______APPENDIX B ______
Note: The terminal IP addresses are allocated by the LAN DHCP server, this is the default factory setting. This may be changed to fixed IP addresses if desired. See Configuring Digi module section. The MAC addresses can be found on equipments’ front panel.
4. Select a terminal to be installed (one at a time) and click “Next”.

______APPENDIX B ______
5. Select a logical COM number for the terminal. This is a remote terminal identifier which will be used in the serial interface program for sending control data to the desired equipment. This logical port number can be changed at a later stage. See Changing logical COM Properties. Click “Next”, the installation will begin. 6. Click “Finish” when the installation is done. Run again the Setup Wizard to install another terminal. The following screen will appear when the Wizard is run. You have an option to add or remove a terminal from the host computer. 7. Go to Control Panel>System>Hardware>Device Manager. All newly created logical COM ports should be displayed under Ports (COM & LPT) heading. A new Multi-port Serial Adapters heading should also appear displaying each terminal with its IP/MAC address. If there are no exclamation marks (!) or crosses (x) on any these two headings the terminals should be working. A serial control interface program may now be run using the newly defined COM ports.
B.3 No Terminal found when running Setup wizard If no terminal appeared on the list, make sure the terminal is powered up and it is connected on a working Ethernet network. Check the LEDs on the terminal. The yellow LED should be turned on all time and the green LED should be flashing indicating there is network activity. Make sure the firewall is turned off (temporarily) during installation. Alternatively, you can install by specifying the MAC address of the terminal. Select “Device not listed” in the list and click “Next”.

______APPENDIX B ______changed go to Control Panel> System> Hardware>Device Manager> Multi-port Serial Adapters. Double click the logical COM port. Click Properties under Advanced. The Network tab with IP properties such as the one below can be seen. Edit the IP address or click Browse to look for the terminal. Click Apply to finish. Note: The terminal IP address should be on the same subnet as the host computer.
B.5 Configuring Remote Digi Terminal Digi Connect ME comes with a built in web server. The most convenient way to access the terminal configuration is via a web browse. IP address, terminal name and terminal configuration may be edited. However, the IP address of that particular terminal and also the http port number are required in order to access into (factory setting of the http port number is 80). Since the initial IP address is allocated by DHCP server once connected to a network, this address may be easily obtained by running the Digi Device Discovery software which can be found in the CD-Rom, 40002265_G.exe. 1. Open a web browser and type in the IP address and the port number,
2. Login as root: Default user = root, password = dbps. If successful, the following screen will appear. The configurations may now be changed. Click “Apply” and reboot if necessary. Note: the Digi terminal takes about 1 minute to reset itself.

______APPENDIX B ______
Warning: It is advisable NOT to disable (untick) the Device Discovery Program or it may cause difficulties in detecting the terminal.
B.6 Serial Interface setting, front panel By default the Digi Connect ME module works only in RS232 mode. Thus, the Serial Comms setting on the equipment’s front panel should be set to RS232 Mode. Other settings such as baud rate, data bits, parity bits and address should be configured to match the setting the control software.
B.7 Limitations on Digi Realport Only TAPI compliant applications or those written to COM 32 API (application programming interface) standards are able to use logical COM ports (RealPort ports).

ETHERNET INTERFACE Mk I Wen browser and SNMP interfaces
C.1 INTRODUCTION Equipment with web browser and SNMP interface option may be accessed for monitoring and control purposes via a web browser or through a workstation running an SNMP client application. Such equipment has been fitted with an Ethernet interface module with a built in customised web browser. Control and monitoring functions supported via the conventional serial comms port are usually supported through the browser and SNMP interfaces. Control and monitoring data is accessible using SNMP implementation versions V1 or V2C.
C.2 WEB BROWSER PAGES These are the pages available with a web browser: Equipment, Configuration, SNMP settings, Information.
C.2.1 Equipment page This is the Home Page for the equipment. It displays current settings and provides links to other pages. Settings are Frequency, Attenuation, IF frequency, Output status (mute/unmute) and Remote (remote/local). They may be changed by entering new values in the boxes or by selecting drop-down options. Once executed by clicking Set new value(s) the page will be updated with new values. Note: If parameters are changed at the equipment front panel (while in local mode) or from a second web browser, the updates are reflected on this page after a delay of 5 to 10 seconds.

______APPENDIX C ______C.2.2 Configuration page This page displays the network configuration settings. Ann admin username and password is required for access to this page. Unit name, site/unit description, automatic IP address (via DHCP server) option and static (fixed) IP may be entered in this page. All units are shipped configured with DHCP mode enabled.
C.2.3 SNMP settings Each unit may be configured to send traps to one or two addresses on a major status change. Each trap can be SNMP v1 or SNMP v2c compatible or both. A trap can optionally be sent on a cold start, i.e. when the unit is powered up.

______APPENDIX C ______C.2.4 Information Page This page displays software version, unit name, unit power up time and contact information.
C.3 INITIAL SETUP On initial setup a network communication has to be established first. On switch ON the equipment network interface will take up to 1 minute to become operational. If the IP address is known simply point the browser to that address. Otherwise, the IP address has to be found by using a Finder utility. This is usually the case when DHCP mode is enabled where the IP address is dynamically allocated by a DHCP server. ‘NovFind.exe’ is the finder utility shipped with the unit. This program should be run on a PC connected to the same network as the equipment. This utility will search and display any compatible equipment active in the network. The utility will display the allocated IP address along with its MAC address. It will also provide a means of setting the IP address in either Static or DHCP mode. This can be done by selecting the desired device, and clicking ‘Configure IP Settings’. A password is required to change the setting and to reboot the device. Note: All login names and passwords are supplied separately from the manual and are specific to each individual piece of equipment. This information is provided exclusively to customers using Novella purchased equipment with the relevant interfaces.
