A multichannel, Counting System 2 (MCCS-2) data acquisition plug-in card for the IBM ISA, MCA and EISA bus architecture has been designed and developed for acquisition of pulsed signal. The card features large dynamic range is achieved with the help of 16-bit pulse counters, fast signal acquisition and a self-testing capability in a single slot card. The MCCS-2 (designed by R & D group, CD) is an upgraded version of MCCS-1 [6]. The MCCS-2 consists of a plug-in interface card (MCCS-PC) for fBM PC and compatibles and a BNC- terminal module (MCCS-BNC). The MCCS-PC is address selectable and can simultaneous monitoring ten independent SCA inputs. An on board programmable timer provides elapsed time measurement. A menu-driven software program is developed for data acquisition and timer control.

IV 1, INTRODUCTION
In nuclear experiments, the signals from a detector are fed to a linear amplifier in a NIM-BIH The output of the amplifier is connected to the input of a Single Channel Analyzer (SCA). The SCA output is a loyic pulse for each event. These logic pulses are used by the counting circuitry for count rate measurement or counting events over specified period of time. For each experimental setup the data is collected and then interpreted using computer or calculator. Further, in order to determine the spatial distribution of events (for example a radiation source), similar measurements from different locations are made simultaneously. In order to ease the installation of such experiments and to improve the turn-around time, it is desired to automate the system. The Multichannel Counting System (MCCS-1) was designed by Research & Development (R & D) group of Computer Division and supplied to various division in Pakistan Institute of Nuclear Science St Technology (P1NSTECH), Institute of Nuclear Power (INUP) and Kundian Chemical Plant-I[ (KNCP-II), The Radiation & Isotopes Application Division (R1AD) and Neutron Diffraction Group ofNPD are requested for upgradation and modification of MCCS-1 system. MCCS-2 is a new designed system described in this report provides a direct interface between SCA outputs and an IBM-PC compatible compuler, capability to interface ten SCA outputs channels instead of seven and address selectable logic allows the user to interface multiple modules simultaneously connected to the computer. The interface card is designed and developed for IBM-PC/XT/AT bus. The data for multiple counting channels is stored on the computer disk along with necessary information such as elapsed time, date, number of channels etc.

2 3- HARDWARE DESIGN DESCRIPTION
MCCS-2 system consists of multichannel counting system plug-in interface card (MCCS- PC), to be installed in an IBM-PC compatibles I/O channel and BNC interface module called MCCS-BNC. The SCA oulpui pulses are terminated on MCCS-BNC interface module through a twisted pair ribbon cable are connected to the interface card within the PC. The block diagram of the overall counting system is shown in Fig 1.
The SCA output is a logic pulse of 0.5u5 duration [ 1 ] for each event. These logic pulses are used by the MCCS-PC interface as input to one of its ten counting channels. A timer enables these counters for a specific period of time.
The heart of the MCCS-PC card is the Intel 3253-5 programmable counter/timer I.C [2]. It contains four registers of sixteen bits each. One of which is reserved for control and remaining three registers can be used either as counters or timers independently. Four £253-5 LCs are used on a card at location U I, U2, U3 and U4, giving a total of 12 user - available registers, out of which one is used as timer and one frequency divider. The remaining ten registers perform pulse counting of the ten independent input signals. Fig. 5 shows the block diagram of the MCCS-PC board.
The LC. layout of the board and the circuit diagram is shown in Fig, 5 & 6 respectively. The various sections of the design are discussed below.
3.1 SIGNAL ISOLATION* CONDITIONING
The pulse width of SCA output signal is 0.5us and its range is from 0 to 6 volts. The incoming signals [6] from MCCS-BNC interface box are isolated electrically from the interface card MCCS-PC using bus isolators (RS 20B-355) to avoid probable damage to the computer from the counting system and vice versa.
The output of a bus isolator is not TTL compatible as required by the computer. Hence these signals are converted to 0-5 volt using two resistor packs of Ik & 330 ohms. The output of potential dividers is fed to line receiver/driver buffers, 74LS244 (U6 & U12) for further use,
32 TIMER
Not relying on the PC system clock that varies from 4.77 MHz to more than 433 MHz depending upon the make and model being used, a 2 MHZ {as basic requirement of 8253-5) crystal is used to generate basic clock for the counter/timers. A 2 MHz clock is divided by 2000 to obtain a square wave of 1 kHz, This square wave output is obtained from counter 2 of U2 that is programmed to function as divider for the incoming clock. The gate 2 of U2 is enabled permanently by pulling it up to 5 volts supply. The counter 1
3 acts as a timer in mode 0. It is loaded with an initial value in milii seconds. The gate I is enabled by software. The OUT 1 is active low until counter 1 contents are made not equal to zero. The OUT 1 signal is inverted and used to enable the gates of various counting channels. When the counter-1 is decrement to zero, the OUT 1 changes its state and disables all the counting channels. The 2 MHz clock can be divided any suitable number by software to obtain a timer resolution from 0.5 us to 32.7 mS.
3.3 COUNTER
The interface has 10 counting channels. All the counters are loaded with FFFF hex initially and each counter starts in count down mode when its gate is enabled. After the specified elapsed time as discussed above, the respective gates are disabled. The counts from various channels are read by software. The present leading is subtracted from the initial value FFFF hex to find the actual events recorded by each channel
3.4 ADDRESS SELECTABLE LOGIC
In MCCS-1 module has limited design features of fixed address. We faced two main problems. The first thing is that the module can be used only for seven channels with no multiple modules and secondly only one device of same address of 300Hex can be used The address selectable logic is introduced in MCCS-2 module to overcome these problems. The 3-£o-8 line decoder 74LS138 on the board serve as address decoders. One function of an address decoder is to produce a signal, which enables the peripherals for a particular address. A second related function of an address decoder is to make sure that only one device is enabled at a time to put data on bus lines. To enable address decoder, G2 signal an address selectable logic is used. Figure (3.4) shows that 8-bit Magnitude Comparators 74LS682, perform comparisons of two eight-bit binary or BCD words and provide P=Q output. In our case Qs inputs, from data switch and other inputs Px, (Address bit 5 to address bit 9 ) is from Octal Buffers/Receivers non-inverted 3-state outputs 74LS244 are feeding to 74LSG82 the P=Q output of this chip is used to enable decoders.

3.5 BASE ADDRESS SWITCH
The MCCS-2 is configured for a base address of 300 Hex (768 decimal). If this base address is already occupied, we can change the Base Address switch setting as shown Figure 3.5. It is essential that each peripheral device, such as MCCS-2, be assigned a unique Base Address (Table-1) with in the range of 300 to 360 I lex (768 to 864 Decimal) and the address is on a 16-byte boundary.

3.6 BUS INTERFACE
The interface with the PCs I/O channel is through buffers/drivers 74LS244 ( U21 and U22) for address and control signals. The data transfer to/from computer is through transceiver 74LS245 (U23). The interface is configured as I/O mapped registers. The address map is shown in Table 2,
3.7 STATUS MONITORING
Data acquisition is done on polling basis by monitoring zero bit of status register at I/O port address of (Base Address+28) hex. When the status bit is raised to logic 1 the data is available from all the ten channels. The 10R signal and porl address (Base Addrcss+28) hex selection line Is logically ORed to enable one half of tristate buffer 74LS244 (U5),

5. INSTALLATION
The interface card (MCCS-PC) may be installed in any IBM ISA, MCA, and EISA bus architecture 1/0 slot available on the IBM-PC motherboard. The interface box (MCCS-BNC) contains ten 50 ohms BNC connectors for getting inputs from ten SCA channels. The (MCCS-BNC) module and (MCCS-PC) are connected using twisted pair ribbon cable and D-type connectors as shown in Fig. 5. The interface card {MCCS-PC) can be assigned a unique base address with in range of 300 Hex to 360 Hex (768 to 864 decimal). At the time of installation, the address of multiple modules can be found as shown in Table-1.

10 After receiving the above information, [he package will execute a Self-Test explained later. If self-test fails, the package will give error message and the system will return back to main NENU. However if self-test is successful, the package will ask the file name in which the data will be stored. If no file name is entered, "MCCS. 000" is taken as the default file name. The screen display will be
Self test in progress
Test Successful Give file name [MCCS.O0O|= File Already Exist Overwrite! Y/N| If no than Give file name |MCCS.000|=
During data acquisition, the information about events in the configured channels, the number of times the data has been collected and file name are displayed on the screen. Alter completion of the data collection, a musical tunc is played along with the necessary information displayed on the terminal. The program will return to (he mam menu after some delay.
6.2 DATA FILE
The data is stored on the hard disk in a sequential ASCII data file. The format of the file is as follows:
Record Name Description Number L CHN The number of acquisition channels. 2, NREAD Number of times the data is collected 3, DTM1E Data acquisition lime in sec 4. DATE Date of the day 5. TIME Si ailing lime 6. STATUS OF " 1 " means the channel is configured. CHANNELS. " 0 " means the channel is not configured. 7. DATA NREAD " records, each record contains counts from all the seven channels.
The data is stored on the disk in file name given by the user however the default data file is MCCS.000,
II 6.3 SELF TEST
Since the counting channels are 16 bit registers, ihey can record only up to 65535 counts. If the events arriving in specified time are more than the above figure, die registers are re-initialized to the maximum value and start counting down. This would give erroneous information. In order to overcome this problem, a self-test routine has been added in the package to record the events for 500ms. The events recorded are scaled up to the time given in seconds in order to determine the probable expected events in the given time.
The test will give a fatal error message if any counting channel is expected to receive more than 65535 events in the specified time and die user is requested to change the data acquisition time before proceeding further.
The self lest may not give accurate indication of number of counts because the nuclear disintegration per second are random in nature. However it gives an estimate of the number of events expected,
6.4 ANALYSIS
This part of the package is left for the users To perform analysis according to their requirements. However graphic routine is included for NPD. This routine displays graph of count versus detector position.
a 7-0 CONCLUSIONS AND SUGGESTIONS
The interface MCCS-PC module is designed keeping in view the requirements of Radiation & Isotopes Application Division and Neutron Counting Channel in Reactor Experiments of NPD. It is a genera I-purpose module and can be used anywhere for counting the events provided the output of counting system is in the form of logic pulses.
The Interface card may be considered funcliouully equivalent lo Counter/Timer (ORTLC 771 with buffered memory option) and NIM-RIN primer. The ndded ;idv;iuiage of more precise control of a resolution of 0.5 uS is achievable.
It has one limitation of using 16 hil counter registers and can record up to 65535 events. However this limitation can be overcome, if required, by cascading various counters in hardware.
The computer technology is improving very rapidly and I/O slots or lius are also changing. The DAQ boards designed iov ISA, MCA OR EISA bus cannot use with the PC having slots PCI or PCMCIA Same problem is faced using a Lap Top computer. To overcome this problem the study of different solutions i.e. a Parallel Port and Serial port (RS 232 Standard) Data Acquisition Systems is carrying on. The new dedicated system will be expected to be useful for field experiments in remote areas.
