IDENT CHARACTERISTIC SPECIFICATION 1.3.5.2 The VHF-2100 does not support the VDL Mode 3 Anti-blocking over-ride functionality speci[ed in DO-271B section 2.2.4 and, more speci[cally, DO-224A section 3.3.5.4.3.5. The [rst portion of the requirement speci[es a transmit inhibit to prevent users from talking over other users already speaking on the Mode 3 channel (anti-blocking). The second portion of the requirement speci[es that this inhibit be allowed to be over-ridden when other users are in a degraded VDL Mode 3 timing state (TS2 or TS3). The VHF-2100 has the ability to detect what timing state other aircraft transmissions are in, however, there is no provision for communicating this information to the \ight crew. Furthermore, there is no provision for the \ight crew to command the anti-blocking over-ride. 1.3.5.3 TSO C163 Paragraph 4e recommends marking the unit nameplate with O(Dev)P when any deviations to the TSO are granted. Rockwell Collins decided not to mark the VHF-2100 nameplate in this manner as this could lead to confusion with the end user. The marking O(Dev)P may be construed as "Development" rather than "Deviation" and may lead the end user to question the utility of the product. All deviations are documented in this Component Maintenance Manual, as required by TSO C163 Paragraphs 5b and 5j. This supplies the end user with the appropriate information and is the method used in all prior TSO approvals of this type of product. 1.3.6 TSO Plus+ Functionality Full TSO quali[cation testing was performed on all implemented functions covered by TSO. For functions not covered by a TSO, quali[cation testing was performed to the applicable performance standard, per TSO Plus+ guidance. Speci[cally, Mode A and Mode 2 functionality was tested to the DO-281 MOPS performance standard. 1.4 FCC Parts 2, 15, and 87, CFR Title 47 Code of Federal Regulations. 1.5 EUROCAE 1.5.1 ED-23B.

TASK 23-12-95-870-805-A01 5. Electrical Description

SUBTASK 23-12-95-870-001-A01 A. General

(1) The VHF-2100 VHF Transceiver supplies air-to-air and air-to-ground communications in the 118.000 to 136.992 MHz frequency band. Electrical connections to the VHF antenna and other related equipment are made through the unit's rear connector. The VHF-2100 contains the transmitter, receiver, control and data processing circuits necessary to perform conventional analog radio and data link functions (ARINC 750) with a compatible CMU.

(2) The paragraphs that follow describe the electromagnetic interference capabilities of the VHF-2100 VHF Transceiver and a electronic circuit functional description for each assembly.

SUBTASK 23-12-95-870-002-A01 B. Electromagnetic Interference

(1) The VHF-2100 is designed to operate aboard aircraft that use either conventional control systems or \y-by-wire control systems, or any combination of both. Fly-by-wire control systems are required to be immune to HIRF, lightning, and FM broadcasts to prevent navigation and \ight control equipment failures.

(a) High Intensity Radiated Fields (HIRF)

1 HIRF is any radiated [eld that has an energy level above 5 volts per meter and is either a one time occurrence (spike or pulse) or recurrent frequencies in the range 30 Hz to 18 GHz. Sources of HIRF include radar (ground based and airborne) and on-board transients from motors and other electrical equipment.

2 There are three categories of HIRF immunity.

a Flight critical equipment must be able to survive without damage and operate properly in an environment of 200 volts per meter conducted or radiated, and 600 volts per meter pulsed.

b Flight essential equipment must be able to survive in an environment of 200 volts per meter without damage, and operate properly in an environment of 20 volts per meter.

c Flight nonessential equipment must be able to survive without damage and operate properly in an environment of 5 volts per meter.

Page 23 23-12-95 Jun 06/05 ROCKWELL COLLINS COMPONENT MAINTENANCE MANUAL with IPL VHF-2100, PART NO 822-1287

(b) Lightning

1 Lightning creates a very high-level-pulse radiated [eld, and also produces high current and thermal energy. When a direct lightning strike to the aircraft occurs, high current \ows through the aircraft skin and exterior equipment such as antennas. The high current causes voltage spikes or pulses to be induced in the internal aircraft wiring. A lightning strike also generates high temperatures at the point of contact because of the high current involved. When \ying in an environment where lightning strikes are possible, exterior equipment must be able to endure the heat caused by the lightning strike. Internal equipment must be able to maintain proper functions during the resulting lightning-induced pulses.

SUBTASK 23-12-95-800-001-A01 C. Electromagnetic Interference Protection

(1) The HIRF and lightning protection of the equipment is accomplished by using [ltering networks for each input into the nickel-plated rear connector. The networks are composed of a ferrite block or beads and feed-through capacitors. The reduction of cooling-hole size reduces the potential for HIRF entrance into the equipment. HIRF interference is further minimized through the use of metallized gaskets at the seams where side covers and top, bottom, front, and rear panels join.

SUBTASK 23-12-95-870-003-A01 D. Chassis

(1) The chassis assembly gives support for the circuit cards, and a plenum to force cooling air across the circuits. RF cables and wiring are routed through the chassis to provide interconnect wiring between circuit cards.

SUBTASK 23-12-95-800-002-A01 E. VHF RF A1

(1) VHF RF A1 contains the radio frequency (RF) functions. These functions include: transmitter, receiver, LO synthesizers, and [ltering circuits. This circuit card assembly contains receiver circuits that convert the VHF carrier frequency to an intermediate frequency (IF) and frequency synthesizers. The transmitter circuits consist of a frequency synthesizer circuit, power ampli[er circuits and monitor circuits.

SUBTASK 23-12-95-800-003-A01 F. DSP/Power Supply A2

(1) The digital signal processor (DSP) circuit of A2 digitally samples, [lters and demodulates the IF input from A1, supplies the baseband signals for transmitter modulation, and controls all other operations of the transceiver.

Page 24 23-12-95 Jun 06/05 ROCKWELL COLLINS COMPONENT MAINTENANCE MANUAL with IPL VHF-2100, PART NO 822-1287

(2) The power supply function converts the nominal +28 V dc input to DC voltages that are necessary for the unit to operate.

(3) The external I/O circuits supply an interface between the rear connector and other functional analog-to-digital (A/D) circuits within the unit. The I/O circuits consists of: ARINC 429 receivers, ARINC 429 transmitters, transmitter audio input, receiver audio outputs and discrete inputs/outputs.

SUBTASK 23-12-95-870-004-A01 G. Rear Interconnect A3

(1) Rear interconnect A3 contains the electromagnetic interference (EMI) and high intensity radiated [eld (HIRF) [ltering and protection for signals entering the unit. A view of the rear connector and rear connector pin assignments is given in Figure 4/GRAPHIC 23-12-95-99B-004-A01. A description of the rear connector pin functions is given in Table 7/Table 23-12-95-99A-008-A01.

TASK 23-12-95-400-801-A01 7. Installation Data

SUBTASK 23-12-95-400-001-A01 A. General

CAUTION: THE ARINC 600-9 SPECIFICATION, WHICH IS THE GOVERNING DOCUMENT FOR ARINC 600 CONNECTORS, REQUIRES (FOR PROPER CONNECTOR OPERATION AND SERVICE LIFE) THAT AN EXTRACTOR MECHANISM BE USED TO AID DISENGAGEMENT AND ALSO THAT A FRAMEWORK BE USED IN THE AIRCRAFT SO THAT ONLY A /0.1 INCH LATERAL MOVEMENT, AND ONLY 0.2 INCH VERTICAL MOVEMENT IS POSSIBLE.

CAUTION: ROCKWELL COLLINS RECOMMENDS THAT CARE BE EXERCISED DURING REMOVAL OF LRUS FROM THEIR MOUNTS FOR ANY INSTALLATION THAT IS NOT IN COMPLIANCE WITH THE ARINC SPECIFICATION.

(1) Damage of the plastic insert of the aircraft rack connector for ARINC 600 avionics equipment is possible during extraction of the LRU. A signi[cant amount of force is necessary to disengage the ARINC 600 connector that interfaces the LRU with the aircraft rack. Excessive side-to-side or up-and-down motion can cause the plastic insert of the LRU receptacle to become damaged.

(2) The paragraphs that follow gives general installation information for the VHF-2100 VHF Transceiver.

SUBTASK 23-12-95-800-005-A01 B. System Requirements

(1) The VHF-2100 VHF Transceiver has the capability to interface with VDL systems as well as support analog voice and data operations. The system con[guration and interfaces are dependent upon the aircraft, installed systems and customer requirements. A simpli[ed block interconnect diagram is shown in Figure 6/GRAPHIC 23-12-95-99B-006-A01. This diagram shows a typical VHF communications subsystem supporting multi-mode VHF communication operation. Other components in this system include: a radio tuning panel (RTP), a microphone, a headset or speaker system, a data control/display and an aircraft antenna. An optional onboard maintenance system (OMS) is also shown in the diagram. An interconnect wiring diagram for a typical VHF communications transceiver system is shown in Figure 7/GRAPHIC 23-12-95-99B-007-A01.

(2) Interconnect Cable Preparation

(a) Observe the following precautions during design and preparation of interconnect wiring cables.

# Bond and shield all parts of the aircraft electrical system, such as generators and ignition systems. # Keep the connecting cables away from circuits carrying heavy current, equipment transmitting pulses, or other sources of interference. # Make all external connections of the equipment through designated connectors, listed on the interconnect wiring diagram. # Digital data bus shields should be grounded to the aircraft structure at both ends and on both sides of all breaks. # The audio cable shield should be grounded at the audio system end only. # Leave slack in cables to allow for free sway of the equipment. Avoid long runs of wire insofar as practicable. # For all twisted and shielded bus wires, make shield grounds at the electronics rack shelf-interconnect points and at production breaks. # Separate AC and DC grounds should be provided. DC grounds may be individual local grounds. # Connect primary power to the components through aircraft circuit breakers (of the appropriate size) as shown in the interconnect wiring diagrams. # After installation of the cabling and before installation of the equipment, perform a continuity check of all interconnect wiring. When the check is completed, apply power and ensure that voltage is present at the pins speci[ed by the interconnect wiring diagram.
