Here is a quick startup note which may help you along.
OK, first lets get GPS
. Use the Settings icon (looks like a wrench).
Select the NMEA
Data Source drop-down box, and choose the port where your GPS
If you are using a standard serial
port, then choose the proper physical port number to match. If, on the other hand, you are using a USB GPS, then you will select the virtual serial
port which was created by your GPS device driver. You may need to try several selections to find the correct port.
(Hint for XP/Vista: Using the Device Manager, look for a serial port which appears and disappears dynamically as you plug
and unplug the USB GPS cable. This is your virtual GPS serial port.)
In either case, if the GPS is connected, powered up, and recognized, then opencpn
will show a pale green background in the upper right window of the toolbar which displays the current
If no GPS is present or recognized, the chart identification window will have a pale red background.
Opencpn automatically configures baud rate, bits, parity, etc.These do not need to be separately specified.
Next, load some charts.
Again, start Opencpn, and use the Settings ("wrench") icon.
Choose the tab marked "Charts".
Use the top window pane to locate and highlight the directories containing your charts, one-by-one. When you have a chart directory highlighted, chose "Add Selection". The directory you selected will appear in the bottom window pane, and be added to the opencpn chart database.
When you have finished selecting and adding chart directories, choose "OK".
Opencpn can share chart directories with any other installed chart navigation
system. There is no need to make a separate directory for opencpn charts.
Finally, choose the green cross in the opencpn toolbar. This action will center the chart display on your current
GPS location, while engaging "Auto Follow" mode for navigation
I hope these rudimentary instructions will help you get started.
