Possible Solutions
If powered by Power over
Ethernet (PoE), check that
the Cat5e cable or the power
sourcing equipment (for
example, the network switch
supplying the PoE) is not
faulty.
If powered by DC input,
check power for 10.8V DC to
13.2V DC. If lower than 10 V
or no voltage present, check
wiring on power side of SE
receiver, repair or replace
cable.
If power is present and SE
coordinator is not
responding, replace SE
coordinator.
Seal housing where moisture
is entering enclosure. Replace
SE coordinator until the old
one dries out.
Check all splices to make
sure cables are tight and not
loose causing high resistant
open.
If power is present and SE
coordinator is intermittently
not responding, replace SE
coordinator.
Replace the SE coordinator.
Check that addresses of SE
coordinator and the SE
receivers are correct. If
addresses are correct,
replace SE coordinator.
