50.1
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.

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.

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.
