Configuring the A325
You can configure the A325 through the serial port using Hemisphere GNSS commands. For
example, you can:
•
Select one of the two on-board applications
•
Select the baud rate
•
Select which NMEA 2000 data message to output on the dual serial ports and the
update rate of each message
Note:
Use the $JSAVE command to save changes you make to the A325’s configuration
for the changes to be present in subsequent power cycles.
For information on Hemisphere GNSS commands refer to the Hemisphere GNSS Technical
Reference (go to
