Rear Panel Connections
Network Ports
The Mix Engine has 2 network ports; the primary port is the AoIP port and
is mainly used for the transport of audio - between the Mix Engine and the
MPPRs, and between the Mix Engine and the Main Studio Mixing Desk. This
network will also provide connection for discovery of devices and Ember+
control, status and metering information.
The control port will provide webserver access to settings. This port is
intended to run on a physically different network, so engineers/operators
can interrogate/set device parameters on the system without their network
overhead impacting on the AoIP network. The webserver can also be
accessed via the AoIP port.
Standard GPIO Connector
This is a 15-way female ‘D’-type connector which has 10 ports with user
assignable direction & function, and a voltage free relay switched output
with normally open and normally closed contacts. The Technician and
Presenter Units have a single connector, and the Mix Engine has two of
these connectors, allowing 20 x GPIO and 2 x relay closures.
When the pin is defined as an input then the pin should be pulled to ground
to activate it. When the pin is defined as an output then when the output is
active the pin will be pulled to ground – and is capable of sinking 20mA.
