Expansion Module Operation

After applying power to the expansion modules, the transmitting (TX) and receiving (RX) LEDs
blink when communication occurs between devices. The following table describes LED activity
and indicators.

1. Verify that the expansion modules are powered.
2. Visually verify that all modules are communicating (both the TX and RX lights are blinking).

Sequence on power-up: Illuminates red,
then green.
Sequence on power-up: One short blink
upon power-up or during memory test; will
remain green if memory test fails. When the
service LED is pressed, the module will
continue to use its normal node number for
communication. However, it will communicate
node 0 if possible (this does not affect
operation).
