3.3.3 Isolated audio and key line connections
Two 5-way connectors provide a duplicated interface for
isolated audio and control lines for connection to other
third party equipment operating alongside the RJ45
connections. These interfaces can be used to replace
the RJ45 connections provided they are connected to
an IO Tu unit’s audio input, usually when installed in a
separate cabinet with PABx equipment.

3.3.4 Power connections
The Sonix Pbx is powered via a 2-core 48 V dc input
on the rear of the unit. This input should be connected
to the managed 48 V dc power output from the Sonix
PM10 power management unit.
Note: As these cables are power feeds they should
be routed within the PA/GA system in a way so as to
avoid contact with signal or audio cables and other high
voltage cables.

3.3.5 General fault output connections
The general fault output is a low voltage, volt free
contact output. The output can be set in configuration
to either normally open or normally closed. It is
recommended that the output is set to normally closed
so a loss of power to the unit will be detected.
