5.3 NGM PCB LEDs Check
Note: Refer to the NGM Support Tool manual
997-547 for further information about
these LEDs.
5.3.1 Software Running
LED 8 should flash approximately 2 times per
second to indicate that the software is running.
Each flash indicates that the software has
completed 50 cycles of its internal routines.
LED 9 flashes 0.2 seconds ON 5 seconds OFF
to indicate that the Secondary CPU is running.
5.3.2 Network Messages
LEDs 1 to 6 flash briefly every few seconds
(possibly up to 60 seconds, typically 5 to 10
under quiescent conditions, dependent upon
the number of nodes). LEDs 1 to 3 indicate
Channel 1 communications, and LEDs 4 to 6
indicate Channel 2 communications. No activity
or long flashes (2 seconds on, 2 to 10 seconds
off) indicate that the channel is not operating.
The long flashes indicate that the NGM PCB is
attempting to re-establish communication with
the other end of the link.
