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

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.

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.
