Meaning and Response
RTS
(DS7)
Request-To-Send signal active; enables transmission on PeerWay.
TXD
(DS6)
Transmitting to the PeerWay.
BUS ACTIVE
(DS5)
Card active; Data is being transmitted or received through the
Coordinator Processor.
+5 V FAULT
(DS4)
PeerWay buffer voltage comparators sense that the main regulator is
out of operating tolerance (high or low).
FUSE BLOWN
(DS3)
Replace Fuse F1 (Supplies power to the PeerWay Buffer Power
Regulator).
STATUS FAULT
(DS2)
The status timer has timed out, indicating the RTS Signal has been
enabled too long and the jabber-halt relay has opened. The RTS
signal is forced OFF to keep the node from interfering with the
PeerWay. The fault could be the status timer in the PeerWay Tap, the
RTS signal on the Coordinator Processor, the Tap Board connection,
or loss of the onboard clock, which is a PeerWay Buffer or Coordinator
Processor problem.
STATUS GOOD
(DS1)
The timer on the PeerWay Tap is in its normal operating m ode.
