12. Using your FX324 MAP in Slave Mode

Slave Mode allows you to use your FX324 MAP as a repeater when its
NMEA input is connected to the NMEA output of another device (GPS,
PC, Navigation System, etc.).
When the slave mode is active, the FX324 MAP uses the waypoints
received through its NMEA input to automatically activate its GoTo
function while continuing to calculate its position using its antenna.
In order to function in slave mode, the following conditions must be met:
- The slave mode must be active in the FX324 MAP:
Menu ADVAN. Tab
- The FX324 MAP serial input must be programmed in NMEA 183 format:
Menu SETUP Tab
- The FX324 MAP serial input must be directly connected to the NMEA
output of the master GPS.
- The master GPS must send the active waypoint through its serial output
in BWC sentences (NMEA 183 1.5, 2.0 or 2.3 standard).
See Digital Output and NMEA Digital Input.
If the formats and connections are correct the name of the waypoint
received is displayed on the GoTo screen. All the navigation information is
then calculated with respect to this waypoint.
The starting position used to calculate the cross track error and the
velocity to destination is your current position at the time the FX324 MAP
receives the waypoint from the master GPS for the first time.
The position of the waypoint received is recorded in the list of waypoints
under the displayed name. Your FX324 MAP will automatically follow and
record all of the other waypoints received.
Note: When the slave mode is active, the GoTo function is only active
for the waypoint received through the NMEA input. It is no longer
possible to activate another waypoint or route.
To return to a normal function mode, you must put the device back into
master mode:
Menu ADVAN. Tab
