Recommendations for Connecting to Other Devices
When interfacing to other devices, ensure the transmit data output from the
V102 is connected to the data input of the other device. The signal grounds
must also be connected.
There is likely little reason to connect the receive data input of the V102 to
another device unless it is able to send configuration commands to the V102.
Since the V102 uses proprietary NMEA 0183 commands for control over its
configuration, the vast majority of electronics will not be able to configure its
settings unless the other device has a terminal setting where you can
manually issue commands.
Default Parameters
Table 2-2 and Table 2-3 provide details on the default port settings, available
baud rates, differential age, elevation mask, and default differential mode.
Note: Use the $JSAVE command to save changes you make to the V102’s
configuration for the changes to be present in subsequent power cycles.
