12.7 NMEA DATA PAGE
The NMEA Data page is very useful to see if an external device (for example a Depth
Sounder) is transmitting NMEA sentences to the CP590. This page can also be used to see
if the GPS Chart Plotter NMEA output is being loaded down by a external NMEA device the
CP590 is connected to (VHF Radio connected but the Radio is not receiving a GPS Position.
Usually the VHF Radio will be connected to the Green and Brown wires). To check and see
if the CP590 is transmitting the 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. Connect the Blue Wire on the CP590 to the junction of the Brown wire and the VHF wire.
The display should look similar to the right side of the figure below:

6. To unfreeze the data, [ENT] must be pressed again.
