2.9 NMEA DATA PAGE
The NMEA Data Page is very useful to see if an External device (example: Depth Sounder)
is transmitting NMEA sentences to the GPS chart plotter. This page can also be used to see
if the GPS chart plotter NMEA output is being loaded down by an external NMEA device.
Example:
Autopilot connected but the CPV550 but is not receiving NMEA data.
Usually the Autopilot will be connected to the yellow wire.
To check to see if the GPS chart plotter is transmitting the Autopilot sentences:
1. Press [MENU]. Move the ShuttlePoint knob to highlight
NMEA DISPLAY and press
[ENT].
2. Move the ShuttlePoint knob to highlight
DATA and press [ENT].
3. The
NMEA DATA page is shown.
4. Connect the Blue Wire on the GPS chartplotter to the junction of the yellow wire and the
autopilot. The display should look similar to the picture below.
5. If no data is shown press the [ZOOM] and move the knob on right side up to change
port.
