Rear Panel Controls and Connectors
The rear panel includes Phoenix type connectors for 16 mono channels of
balanced audio outputs, parallel control inputs, configuration DIP switches,
microphone phantom power dipswitch, serial control connector, 6-pin mini-
DIN GPS connector, RJ45 network jack, stereo line inputs, 5-pin XLR
microphone connector, and the power input jack:
Audio Outputs
Phoenix type screw terminals supply analog line-level balanced audio
suitable for connection to a multi-channel amplifier or powered
loudspeakers.
Discrete Control Inputs
Sixteen discrete inputs can be programmed in a variety of ways to operate
the unit. Please refer to the TraXX Configuration Software section for
programming details. Each input can be individually configured for either
contact closure or voltage input operation.
By default, the rear control inputs are configured to play files 1-16 to
channels 1-16. For instance, input 3 will play file 3 to channel 3 when
triggered. With the default input configuration, files will play and loop for
as long as the input is maintained.
RS-232C Serial Connector
A serial cable is
provided with each
ProTraXX.
This input is a standard DB-9 male RS-232C connector, intended to be
connected to a PC or control system using a straight-through (not null-
modem) 9-pin cable. The pinout appears below. Please refer to the
Serial
Protocol
section for a list of control commands.
