Setting External Alarm Inputs
The IDU-C, IDU-R, IDU-E-AL and the new style IDU-E have four external
alarm inputs and four external alarm outputs in the form of dry-contact
relays. The Alarm interface is located on the front panel of the IDU-C and is
a 25-pin D-type female connector. See
Appendix B
, for wiring specifica-
tions and pinout. You may enable or disable each of the alarms and config-
ure the alarm description text appearing in the alarm trap message. The
ODU sends the alarm within less than a second from actual alarm trigger.
