I have a problem communicating GPS info from my 270ML to the chart plotter (a PC)When first connected it gets a GPS fix but looses this after a minute or so. Then at occations I get a new fix, which disappears rapidly.
The error message in the chart program is The program receives a telegram which is longer than the specification for NMEA 183
Anyone able to give me some guidance?

Assuming you have GPS input to your 1732 (i.e. GP310/320 sensor), you'll need a 7 pin NMEA data cable (000-154-028) wired to a D-sub 9 pin (serial) plug. The shield goes to pin 5, blue to #3, & white to #2. Jumper pins 7 & 8 together. The 7 pin cable goes to Data port 3 of the 1732.
yesss! On the top line, click on " view", then click on " on water mode"
you will then have all the navigations needed for running your boat...better yet, click on "sphere" on the bottom line and see your boat showing your displacement on the chart...I love it !!!
Check to see if this is a power issue by connecting to shore power and fully charging your batteries overnight with instruments off. While still connected to shore power, with batteries fully charged, turn on C80 navigation system. If the loading screen comes on and does not reset, then try holding down the button immediately to the right of the red power button for at least 3 seconds to see if the system re-boots.
I think you have a C- Map card (black colour)clean the contacts with a contactcleaner if it not works try the card somewhere else
The C-Map card have problems that they work for a while and than stops inside the card a some memorychips and they losing contact
There is a feature in these chartplotters called "Plotter Mode" that is often misunderstood and causes the exact problem you describe.
Press menu.....chart setup.....and scroll to the bottom until you see Plotter Mode in the list of options. It should be set in the OFF position.
If you have more than one display networked onboard check the setting in each one invividually.
What Plotter Mode does is allows the chartplotter system to access range scales not supported on the chart. It is not normally used for map-based navigation but more so for chartless electronic plotting (it can display routes, waypoints and track-recorder breadcrumbs.) open-ocean cruising, or for ultra-precise GPS operations (like a precision anchor drop, finding a very specific location etc. When plotter mode is on you can zoom in to a very, very small working area. The indicator it is enable is the cross-hatch background on the screen, the lack of map information, and the NO CHART DATA watermark on the screen.
