Configuring the Receiver 4
Configure the Port Input/Output communication settings for
communicating with the Autopilot system, other external hardware
devices, and software programs. Table 4.1 describes the input settings.
The default port settings are:
Note – The AgRemote utility, when connected to an GPS 5200 receiver
receiver, automatically resets the receiver port communication settings to
8-O-1 TSIP 115 K. This enables optimal communication with an office
computer. If the receiver is to work with an Autopilot system, however, the
receiver port communication settings must be 8-N-1 TSIP 38.4 K. To work

Setting Description
None Inputs nothing to the receiver.
TEXTB The receiver can accept ASCII data from an external device, such as a chlorophyll
meter, on Port A, merge it with NMEA GPS data, and output the combined data on
Port B. The incoming data must be limited to 66 ASCII characters and terminated by
a carriage return and line feed (hex characters 0x0D 0x0A). The NMEA string
outputs as $PTNLAG001,*<2 digit checksum>.
For the receiver to output the combined NMEA string, NMEA must be selected as
the output protocol on Port B.
TEXTA See the description for the TEXTB setting (above). TEXTA input outputs text on Port
A. The default port settings are 8-N-1 TSIP 38.4 K. These may vary by product.
RTCM The receiver can accept RTCM data from an external DGPS device, such as an
external radio.
TSIP The receiver can accept or output TSIP data packets from the port when using the
optional AgRemote program or using the AgGPS 170 Field Computer.
RtkLnk The receiver can accept real-time corrections (CMR data) from an external device
such as a Trimble radio.
