Preparing for the Tests
Perform the steps below before starting the system test:
1. Place the CPU board jumpers and switches to the factory-set positions. Refer to the
processor manual for jumper and switch settings. The numbers in parenthesis refer to
the pins onto which to install the jumper, (e.g. J1 (3-4) indicates the jumper is on
pins 3 and 4 of J1).
2. Plug the female end of the AC power cable into the rear of the computer module and
the male end into a properly grounded outlet.
3. Connect the video cable to the 15-pin connectors on the monitor module and on the
processor card in the computer module.
4. Connect the Host/LED 15-pin cable between the Host/LED ports on monitor and
computer modules.
5. Attach the monitor power cord from the monitor to the power receptacle on the back
of the computer module.
6. Connect the serial loopback connector(s) and the printer cable to the appropriate
connectors and connect a PC/AT keyboard to a keyboard connector on the monitor
module. Figure Chapter 2 -1 illustrates the wiring necessary for the loopback con-
nection.
