ARC Diagnostics
There are two board level diagnostic tests available that are enabled by setting the ADDR switch. The
top cover must be removed from the ARC module to allow the test LEDs to be observed.
VOX Input Test
When ADDR switch is set to “A,” followed by a board reset, the LCD will show DIAG:
VOX
I
NPUT
.
This indicates that the ARC board is in diagnostic mode for the VOX1 and VOX2 inputs.
When audio is detected on VOX1, LED 3 on the PCBA illuminates. LED 3 turns off when audio is no
longer detected at the VOX1 input. Likewise, when audio is detected on VOX2 input, LED 4
illuminates. LED 4 turns off when audio is no longer detected at the VOX2 input.
Input/Output (Switch B)
When ADDR switch is set to “B,” followed by a board reset, the LCD will show DIAG:
I/O. This
indicates that the ARC board is in the diagnostic mode for testing the inputs and outputs.
When Input 1 is activated, Output 1 will be activated. When Input 2 is activated, Output 2 will be
activated, etc. This sequence is true for Input 1 through Input 8.
