2. (1) 2 channel oscilloscope with 2 suitable probes
 
3. (1) Computrol Model 14-0003 Comtrol 1 Remote Tester with extender board and power lead
 
4. (1) Coaxial cable with male PL-259 connector at one end, and male BNC connector at the other end
 
5. (1) Frequency counter capable of measuring frequencies in the kilohertz range, with suitable test cable
 
6. (1) 30-0020 assembly to be tested
 
7. (3) Miniature banana plugs with wire loops attached, suitable for attaching probes
 
8. (1) Rusco Model RS-30 card reader with power supply and 4 peripheral connectors attached to the data cable, such that each connector wires the reader to a different port
 
9. (1) Keycard compatible with the Rusco RS-30 card reader
 

TEST SETUP

Set up the equipment in Item 1 of the "Equipment Required" section according to the "Initial Hookup of Multiplex Test Set and Cage" in the Installation and Operation Guide for the Computrol Model 14-0003 Comtrol 1 Remote Tester, Document Number 90-0025. Make sure the power to the card cage is turned OFF.

1. Plug the extender card with the power cable for the Comtrol 1 Remote Tester (item 3) into any FIM slot in the card cage (item 1.) Connect the white power connector to the corresponding connector on the tester (J2.)
 
2. Connect the end of the coaxial cable (item 4) with the male PL-259 connector to the female PL-259 connector on the tester (J1.)
 
3. Connect the other end of this connector to P1 on the card cage. It may be necessary to remove one or more cards to reach this connector.
 
4. Set the 14-0003 Comtrol 1 Remote Tester as follows:
 
a. Once/Cont switch to Cont
 
b. AR0 to AR5 to the binary representation of the address of the first channel of the card reader board
 
c. AR6 to AR10 to the binary representation of the Common Logic Board address
 
d. SS1, SS2, and DAACK low (off)
 
e. DR0 through DR15 low (off)
 
f. Set the rotary switch to the DFM position
 
5. Connect the trigger of the oscilloscope to the jack on the remote tester labeled TTM* using one of the miniature banana plugs (item 7.)
 
6. Connect the ground of the scope lead to the jack on the tester labeled GND using another one of the miniature banana plugs.
 
7. Connect channel 1 of the oscilloscope to the jack on the tester labeled MON using the third miniature banana plug. Connect the ground of this scope lead to the GND jack on the tester.
 

ADJUSTMENT PROCEDURE

1. Plug the 30-0020 Card Reader interface to be tested into the extender card.
 
2. Connect the frequency counter (item 5) to TP1 on the Card Reader Interface board. Connect the ground lead of the cable to TP2.
 
3. Set the frequency counter range and function to measure 4800 Hz.
 
4. Turn on the power to the card cage.
 
5. Vary R19 until a reading of 4800 Hz is obtained.
 
6. Disconnect the frequency counter and power off the card cage.
 

TEST PROCEDURE

1. Connect the card reader (item 8) to the peripheral connector on the card reader interface using the connector wired for channel 1 operation.
 
2. Turn on the power to the remote card cage and to the card reader.
 
3. Set the oscilloscope to trigger on the rising edge of TTM*, such that the receive message is visible on channel 1 of the oscilloscope.
 
4. Observe the data portion of the received data message on the scope. Insert the badge into the reader, and observe that the data portion of the received data message changes to match the card data being read. (It will probably not be possible to verify the data bit-for-bit. This test is intended only as a rough guide to the operability of the unit. When replacing the card reader interface in the field, each card reader connected to the board should be verified to allow access to the proper individual. This will ensure the data being passed to the computer is correct.)
 
5. Set the Once/Cont switch on the remote tester to ONCE.
 
6. Set the DAACK switch on the tester to 1 (on.)
 
7. Press the momentary switch adjacent to the Once/Cont switch
to DAACK the card reader channel.
 
8. Verify that the received data signal on the scope returns to its previous state.
 
9. Connect the card reader (item 8) to the peripheral connector on the card reader interface using the connector wired for channel 2 operation.
 
10. On the remote tester, set AR0 to AR5 to the binary representation of the address of the second channel of the card reader board.
 
11. Observe the data portion of the received data message on the scope. Insert the badge into the reader, and observe that the data portion of the received data message changes to match the card data being read.
 
12. Set the Once/Cont switch on the remote tester to ONCE.
 
13. Set the DAACK switch on the tester to 1 (on.)
 
14. Press the momentary switch adjacent to the Once/Cont switch to DAACK the card reader channel.
 
15. Verify that the received data signal on the scope returns to its previous state.
 
16. Repeat steps 10 through 16 for channels 3 and 4 of the card reader, using the appropriate peripheral connectors on the card reader cable, and the correct settings for AR0 through AR5 on the remote tester.
 
17. When the tests are complete, power off the card reader and the card cage.
 
18. Disconnect the card reader from the Card Reader Interface and remove it from the extender.
