Accessing the Auxiliary I/O interface on the
redundancy controller
Remote control and monitoring of the redundancy switching
system is accessible via the 19-way Auxiliary I/O connector
on the redundancy controller.
To use this 19-way connector, you need a 19-way
Mil-C-26482 series plug, part number MS3116J14-19P.
Figure 14 on page 52 shows the monitor and control interface
at the Auxiliary I/O connector of the redundancy controller.
Contacts are shown in their de-energised state.
Relay contacts indicate the following faults and operational
status of the redundancy system (the four relay contacts share
a common contact connection):
• Stream 1 Fault
• Stream 2 Fault
• Stream Selected
• Redundancy Controller Fault
Inputs are provided to allow remote control via contact
closures:
• control source
• Auto or Manual Mode
• stream selection
The RS485 connections parallel the two BUC RS485
interfaces to enable remote control of both BUCs using a
Remote Controller 6570, or using serial commands with a PC
running terminal-emulating software.
