Hi |Emma,

sounds like there is a problem with the COM ports. I always connect my AIS and GPS to the the same USB sockets on the computer. The mesage you are getting is one I see sometimes if either the AIS is not connected at all or if it is connected via a different USB socket.

Regards

Ed

Hi Edsailing,
somewhere in this cruising forum I read that you have experience with AIS connection to Open CPN with the Nasa AIS Engine.
I just installed Open CPN. The connection with the GPS was ready in notime.
But the connection to AIS does not work.
May I explain the situation first?
I work with a laptop with XP. The connection between the the AIS engine en the laptop is vis a serial-to-USB cable (Tweex).
When I connect via the buttons on top of the Open CPN screen tha system says: "Cannot open AIS port COM". Suggestion: try to close other applications".
Well, I am shure that is the right Com-port and no other applications than Open CPN are active.
Are you able to help me with this problem?
Kind regards,
Wim Havers
