What to do
Ensure IRIG-B cable is
connected, check cable
functionality (i.e. physical
damage or perform
continuity test), ensure
IRIG-B receiver is
functioning, and check
input signal level (it may
be less than specification).
If none of these apply,
contact the factory.
Set the date and time in
S1 RELAY SETUP.
If alert doesn't self-reset,
then contact factory.
Otherwise monitor
recurrences as errors are
detected and self-reset.
Check Ethernet cable and
Ethernet connection.
Check health of the
network. Check status of
external routers and
switches. Check that IP
settings are not 0.0.0.0
Increase ventilation to the
surroundings.
Replace the rear
communications
daughter board with the
correct board.
Contact factory.
Validate the RMIO Module;
check CANBUS
communication.
