This is a standard RJ-45 jack used to connect the ProTraXX to a network.
Control (UDP), file transfer (FTP), and time (NTP) protocols are supported.
Network settings can be configured using the front panel menu.
Configuration DIP Switches
Four small DIP switches near the power connector are used to configure the unit.

Ground Lift (DIP 1)
The Ground Lift feature can sometimes help in situations where audio hum
or other noise is being caused by potential ground loops. A Ground Lift
disconnects the internal ground from the ProTraXX’s metal chassis, reducing
the chance of ground noise affecting the ProTraXX’s electrical systems (i.e.
audio outputs/inputs, etc.). This feature is configured using switch #1 on the
bank of DIP switches. By default, this switch is set to the OFF position
which grounds the ProTraXX to its chassis. You can implement a ground lift
by setting this switch to the ON position. After that, the ProTraXX’s ground
will be isolated from the chassis.
Unused (DIP 2)
This dipswitch is unused on ProTraXX.
Firmware Recovery Mode (DIP 3, Unlabeled)
This switch puts the ProTraXX in a recovery mode in which you can update
the firmware. Use this mode to update to a working firmware version if a
regular firmware update fails (due to power failure during update, corrupt
firmware file, etc.)
