Configuration DIP Switches
Four small DIP switches on the side of the unit are used to configure various
hardware related settings.
NOTE: For units that are being installed in equipment racks, it’s a good
idea to configure the DIP switches before installing the rack mount kit.

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 RideTraXX‟s metal chassis,
reducing the chance of ground noise affecting the RideTraXX‟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 RideTraXX to its chassis. You can
implement a ground lift by setting this switch to the ON position. After that,
the RideTraXX‟s ground will be isolated from the chassis.
Input Mode (DIP 2)
This switch configures the discrete control inputs for either dry contact
closure operation or voltage input operation. For voltage input operation, the
input voltage should be at least 12VDC and not more than 24VDC. See the
Discrete Input Control
section of this manual for more details.
Firmware Recovery Mode (DIP 3)
This switch boots the RideTraXX in a recovery mode in which you can
update the firmware in the case the unit is unbootable. 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.)
