7.3 Test

Mode

Reference Drawing:
Insert; CompuLink Interface ...............................................Drawing A-164750

The console has built in test functions for the data input and the scoreboard output.
These tests will help isolate system problems and verify proper operation.

To test the scoreboard output, press the <

ALL ON

> test and the <

NUMBER TEST

>

keys. When pressed, these keys will put the specified pattern on the scoreboard.

To test the data input, use the <

LOOPBACK…

> test keys. Refer to Drawing A-

164750. Pins 2 and 3 of J6 on the All Sport 5100 console will need to have an
electrical connection made between them. To make this connection, place a bent
paper clip or a similar wire from pin 2 to pin 3 of J6. When this is done, pressing any
of the loopback keys will send that data out on pin 3 of J6 on the console. The data
should show up on the scoreboard. If this test works, then the data input on the
console is functional.
