Connections
• There are three main connections that will be used any time the RTrak-Lite is in full
operating mode: Power, GPS Antenna and Radio.
Power
The RTrak-Lite can be powered with any 9-20 VDC source. This makes it perfect for
use in a vehicle, boat or just about any other mobile form of transportation. The power
jack is a standard coaxial 2.1mm I.D. jack with a positive center (tip) polarity
The included lighter cable is perfect for most vehicle applications. In portable or human
power applications, such as a bike or hiking, a battery pack may be used to power the
tracker. A 12VDC gel cell or similar Lithium-Polymer style battery would be sufficient.
GPS
The GPS connection is a standard polarity, SMA female RF connector suited to mate
with the included GPS active patch antenna. Be sure to tighten antenna connector finger
tight. DO NOT use a wrench to torque the connector tight. This is not needed and risks
damage to the connector or main RTrak-Lite board.
Radio
The radio interface is a standard RJ-45 ethernet style connector. All required signals to
connect the tracking to any VHF/UHF FM radio are available at this connector. A
interfacing cable with a pre-installed RJ-45 connector and bare wire ends is included with
the tracker package. For a pinout, please see Appendix A.
Programming Port
The programming port is a stereo 2.5 mm jack used only when the RTrak-Lite needs to
be configured for operation. This is a self-isolating jack that is engaged only when the
programming cable is inserted. Failure to remove this cable during normal operation will
block GPS data from getting to the on-board OpenTracker. The cable must be removed
to restore this internal connection.
