CONSOLE I DIAGNOSTIC TESTS
The Postpay-Prepay Console I can perform a number of diagnostic tests to check the operation of
various components within the unit. Tests can be performed while connected to the site controller
or totally independent of it.
Start Diagnostic Mode (With Site Controller)
1. Insert the Supervisor key and turn it on.
2. At the COMMAND prompt, type 9 and press ENTER.
3. Select the desired test through the numeric keypad. The test selected will continue until it
completes or the 0 key is pressed.
End Diagnostic Mode (With Site Controller)
1. Press ENTER while the self-test menu is displayed.
2. Turn off and remove the Supervisor key.
Start Diagnostic Mode (Without Site Controller)
NOTE: If your Console I has a Console II program (V5.2 or above) use the diagnostic tests for
Console II.
1. Turn off power to the console. Remove the four screws from the bottom of the console and
carefully separate the upper housing from the lower housing.
2. Change switch SW3-4 on the CPU PCB to the closed position and turn on power to the
console. The console performs its own stand-alone self-test. The display shows the current
version level of the console and the self-test menu appears.
3. Select the desired test through the numeric keypad. The test selected will continue until it
automatically ends or until the 0 key is pressed.
End Diagnostic Mode (Without Site Controller)
1. Turn off power to the console and change switch SW3-4 on the CPU PCB to the open
position.
2. Carefully set the upper half of the console on the lower half and replace the four screws in
the bottom of the unit. Turn on the power.
Diagnostic Tests
0 - Display Version Number: Press the 0 key. The console redisplays the software version
number.
1 - RAM Test: Press the 1 key. The RAM test checks the RAM on the CPU PCB and reports the
results immediately. This test will exit to the self-test menu after a short wait. If this test fails, the
CPU PCB must be replaced and no other tests are valid.
2 - ROM Test: Press the 2 key. The ROM test checks the ROM (program) on the CPU PCB and
reports the results immediately. This test will exit to the self-test menu after a short wait. If this
test fails, the CPU PCB must be replaced and no other tests are valid.
