RX375P
ChapteR 1 IntRoDUCtIon
The RX375P is a smart antenna that tracks GPS and SBAS (WAAS, EGNOS, and MSAS) signals. The RX375P provides sub-meter performance
with 2.0 ft (60 cm) accuracy 95% of the time. It utilizes COAST TM technology during differential outages. The RX375P is also capable of using
e-Dif ® and L-Dif ® technology.
featURes
The RX375P has several features that will enhance the product’s
performance.
• Two RS232 serial ports
• One Tri-colored LED
• Radar-simulated pulse output
• CAN communication
• Centimeter-level accuracy using Crescent technology in a rugged,
all-in-one enclosure
• RTK baselines of up to 5 km
• Supports CAN, NMEA 0183, NMEA 2000*, binary for
communication with external devices
* To use the A101 in a NMEA 2000 network requires NMEA
certification and a NMEA2000 adapter cable
• Wide operating voltage range of 7-32 VDC, providing high
transient protection for any power source
• Integrated 2D tilt sensor enables offset corrections
• 1 PPS timing output
LED
The RX375P uses one tri-colored LED:
• Red indicates the power is on
• Amber indicates a GPS lock
• Flashing Green indicates DGPS is being acquired
• Green indicates a DGPS solution
Radar-Simulated Pulse Output
The radar-simulated pulse output provides accurate ground speed. The
RX375P uses pin 12 for the speed out pin. Pin 12 will output a square
wave with a 50% duty cycle. The frequency of the square wave varies
directly with speed. 94 Hz represents a speed of 1 meter per second,
or a 28.65 pulse per foot traveled.
NOTE: Pin 12 does not have any form of isolation or surge protection.
It is STRONGLY RECOMMENDED to incorporate some form of
isolation circuitry into the supporting hardware if Speed Radar
Pulse output is to be utilized.
CAN
The RX375P features Controller Area Network (CAN) to handle
communication between CAN-based devices. The RX375P supports
a selection of NMEA 2000 messages that can be broadcast on a
CAN bus. The following table provides a listing of the NMEA 2000
commands that are used.

ChapteR 2 InstallatIon
pRepaRatIon
Before beginning the installation, thoroughly clean the mounting area.
Park the vehicle on a clean, level floor with adequate clearance to work around.
Do not attempt to loosen or attach any fittings while the engine is running.
Photos and illustrations may vary form the actual components provided. This may be due to different installation options, operation modes or
production models.
Always try to use original parts. Built to the highest standards of safety and reliability, TeeJet Technologies parts are to be used for this system
as others might jeopardize the safety and function of the system. TeeJet is not responsible for any redesign or adaptations of the RX375P. Any
changes to the RX375P voids the company warranty.
