Don't be sorry Don; the problem is my abject incompetence.

I'm going back to paper charts.

Steve (totally confused).
It's coming to that. Enjoy your paper charts while you can. NOAA has made pretty clear their intention to phase out paper charts and replace them with vector charts (ENCs). Looking at how long it took to phase out LORAN, though, I wouldn't be too worried about the paper charts.

To work with any computer program, but especially an open source project like OpenCPN, a fair amount of technical knowledge is needed. One of the great things about this forum is there are lots of people here who will help you acquire as much of that technical knowledge as you need and have the patience to learn. Keep working on getting those western Caribbean charts and you'll find you know a lot more about computers than when you started.

What very polite way of not answering "YES" to my initial question. Fabbian, your diplomacy is much appreciated.

Steve.

Steve..

The charts cover very local areas and you have to zoom in sufficiently to the name of the port they cover before they activate. Use the OpenCPN feature 'Show Chart Outlines' in the Toolbox to see the red frames containing the chart areas. Go to 'Charts' and click the 'Full database rebuild' and then OK.

On a different note, seasoft has gone off line. Any other reliable sources out there as I forgot the download pages they were linked too, you know the ones that took for ever and were time limited? Feel free to contact me directly if this is not an appropriate question.

Thanks Tore,

I'll try that. I'm not sure this copy of Opencpn isn't isn't a bit corrupted; now it's not recognising my Garmin handheld...

Steve.

Simple steps you can take to check things out;
1. Attach the garmin to your computer and see if it is recognized
2. Check to see under what com device its registered if it has a serial adapter and if USB no issues.
3. Run a different program, perhaps one of garmins software offering and see if it recognizes your device. If so then
4. Check the settings in OpenCPN under tools to make sure you have set the device up properly in OpenCPN.
5. Check to make sure your garmin is talking NMEA and not garmin proprietary protocal or other.

Give her a shot and see what happens.

1 How do I know that my computer has "recognized" my garmin?
2 What is a "com device"?
3 I have no other programs that might interface with gps.
4 What are the correct settings in Opencpn?
5 How do I know what my garmin is talking, it doesn't say anything to me...?

Steve.

Even in Cartagena there must be a wizzkid around to help you a bit.
Asking a few neighbouring yachties maight save you a lot of time.

Anybody know where I can find an explanatory list of nemonics used in OpenCPN's vector chart section 'Mariners standard'. I want to adjust the displayed CM93 chart to only show the coloured sea background,soundings and navigation marks.

Steve.
1. When you connect your Garmin GPS to your USB port you can open Device Manager (using Control Panel). Find "Ports (COM & LPT)" on the list. Click the "+" sign to the left of that item to see the entries for that category. If the computer has recognized your GPS you should see it listed.

2. A "COM device" is a communications device. It refers to anything which is connected to the computer via a serial port. Serial ports were called "com" or communications ports because in the early days the most common devices connected to them were modems, used to allow computers to communicate with one another over telephone lines.

3. You're probably right, but if you find your GPS listed under Ports in Device Manager but you still can't get OpenCPN to communicate with it revisiting this issue might be advised.

4. Open the toolbox in OpenCPN. Select the "GPS" tab. The NMEA Data Source field should list the com port which was associated with your GPS in the Device Manager Ports list. If not, click the little triangle at the end of the field to see the list of ports OpenCPN knows about and choose the one associated with your GPS. Com ports are identified by number, so if your GPS shows up in Device Manager associated with COM7 you'll want to choose COM7 from the list in OpenCPN. The NMEA Baud Rate field should be set to 4800. For diagnosing problems, check the "Show GPS/NMEA data stream window".

5. Most Garmin GPS receivers allow you to set interface options. Choose NMEA rather than GRMN. That will cause the GPS to send NMEA sentences to OpenCPN rather than using the proprietary GRMN format which OpenCPN can't process. If you checked the "Show GPS/NMEA data stream window" you'll be able to see the text coming from your GPS in a little window that OpenCPN puts on the screen. As you watch that data stream you'll probably recognize a few items as latitude, longitude, course over ground, speed over ground, and so forth. Usually all you're looking for it evidence that readable data is flowing from the GPS to the program.

Tore, I agree with you that almost all the abbreviations used on the Toolbox/VecorCharts page are so secretive that even with Google you don not find out their meaning.
I also do not know what almost any of the *mariners standard* items mean. Also Scamin, ATON labels and Meta objects are incomprehensible items to me. With trial and error I got what I wanted (but thus do not know for sure what I have).

Maybe someone has the secret rosetta stone for the translations ??? Anyone please?

Good luck

Peter
