Monitor Module
The optional Monitor Module provides down stream routing of Output Monitor from each Output ‘Fin’, the
Input Monitor form the Crosspoint and the Monitor Loop Input to eventually produce the Monitor Output.
These Signals are also routed to an EDH monitor for signal integrity checking; the results of which are
passed back to the Control System.

The monitor module Output Monitor BNC is switched from the main processor and control system by
sending serial control messages in the same way as for normal outputs. Before this will work the router must
be configured to say what destination number the monitor BNC will respond to, using the telnet command
commssetup
. This is usually a number outside the normal destination range of the router. Serial messages
to the destination then use the source number to select which output is to be monitored.
The automatic signal detection using the EDH monitors is controlled from the Ethernet Telnet commands
such as
monallip
and
monallop
and these are detailed in Appendix A.
