Communication Indicator
The Communication Indicator provides an indication of the success or otherwise of communication
with the display console, and of the running state of the computer program.
Carefully observe the Communication indicator and the display console at power on and through self-
test, and then use the following chart to help decide the course of action.
Communication Indicator Indications At Power On ACTION
From the moment the system power is applied, the
COMM indicator does not illuminate. During and
after the self-test period of eight seconds, the COMM
indicator remains off.
The computer is not running.
Check status indicators (D2 through D6).
Try to reset the system by powering off and on again.
Listen to the computer for the relays to click. If they do
not click, replace the System Chip
If not successful, replace the computer.
If the relays do click, replace Communication chips IC1,
2.
From the moment the system power is applied, the
COMM indicator does not illuminate. The display
console, which never goes to normal, continually reads:
“No Communication with MicroGuard.”
Communication with the display has not been made.
Is the display console connected?
Check connector and cabling to the display console.
At the moment power is applied, the COMM indicator
flashes briefly, then switches off. After a few seconds,
the COMM indicator starts to flash at a fast rate and
never stops.
This is the normal operation of the communication
between the computer and display console.
