Auxiliary I/O interface of the redundancy controller
The Auxiliary I/O interface of the redundancy controller
enables you to perform the following functions remotely:
• monitor operation of the redundancy switching system
using the isolated relay contacts
• switch streams using external signals
Most of the remote control functions are achieved by
grounding the appropriate control signal to 0 V.
For details about the Auxiliary I/O interface of the redundancy
controller see page 51, Accessing the Auxiliary I/O interface
on the redundancy controller.
NOTE
The redundancy controller does not have a
serial remote control facility. However, serial
remote stream switching and monitoring of the
redundancy system alarms are available using
the BUC command set via either of the BUC 1
Serial/BUC 2 Serial connectors.
