Configuring input/output communication
The port input and output settings appear in the first screen. In
Figure 5.2, the port is set to accept TSIP inputs at a baud rate of 115,000
with a parity of 8-Odd-1. The outputs are TSIP, also at a baud rate of
115,000.
Figure 5.2 Communication settings
To communicate with the AgGPS Autopilot, EZ-Guide Plus, or EZ-Steer
systems, or with external hardware devices and software programs,
configure the port input/output settings. Table 5.1 describes the input
settings.

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,<up to 66 ASCII characters>*<2 digit
checksum><CR><LF>. 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.
