ChaPter 1 IntroDUCtIon
The RX370p is a smart antenna that tracks GPS and SBAS (WAAS and EGNOS) signals. The RX370p provides
sub-meter performance with 4.9 ft (1.5 m) accuracy 95% of the time. It utilizes COAST TM technology during
differential outages. The RX370p is also capable of using e-Dif ® and L-Dif ® technology.
featUres
The RX370p has several new features that will enhance the product’s performance.
The primary features include:
• 2 RS232 serial ports
• LED
• Radar-simulated pulse output
• CAN communication
LED
The RX370p 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 RX370p 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 RX370p features Controller Area Network (CAN) to handle communication between CAN-based devices. The
RX370p 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.
