Possible Solutions
Check rotary switches on all
receivers on that bus to be
sure there are no duplicate ID
numbers.
Replace receiver with new
one until the old receiver
dries out. Seal any point
where moisture is entering
the receiver housing.
Reconfigure the bus run to
make sure receiver is within
900 m (3000 ft.) of the
transponder.
Check all splices to make
sure cables are tight and not
loose causing high resistance
open.
If power is present on BUS+
and PWR+, between 7.5 VDC
and 10.5 VDC on bus and
10.5 VDC and 13.5 VDC on
power replace receiver.
Go to the software dialog
Setup receiver configuration.
Increase jamming threshold
by one degree at a time until
jamming stops and receiver
returns to normal. If jamming
persists after increasing level,
relocate receiver or attempt
to identify and minimize the
jamming source.
