Autopilot Output Device Open Failed

Dotdun/George....

I think it is a bug. Seems like an internal race condition between the NMEA input port setup, and the A/P output port setup. Never seen before.

I'll look into it.

Great Dave, Thanks. It was quit a hassle to get it clear, and I'm happy with the support I got to find it and mark it as a bug.

If there is anything you would me to test on this one, please let me know. Still have 2.5.0 and 3.0 installed on my Windows7 laptop.

I have been trying to get my autopilot to follow a route from OpenCPN also and have not had any luck. In going through the log file I discovered a similar failure ... Here is a log file:

I use a usb bu-353 puck gps.

Ais input is from VHF radio through usb to serial connection.

It seems to input nmea data through the serial cable, should it output data through the same cable? (Different pin of course!)

I have tried every imaginable wiring combination with no luck!

Is this a related problem or do I have something else wrong?


Thanks for the support of a great program.

Thanks, Steve

Steve...
Your problem is that you obviously try to send the data for the autopilot to your AIS/VHF. Is it what you want to do?

I was hoping I could use the same usb-serial connection to output to the autopilot. The AIS is inputting to the computer OR the computer is outputting to the autopilot, I can make either of them work... Just not both at the same time!
I seem to remember reading somewhere that GPS and autopilot could only be on com 3... Is this correct? If so it would not be possible to have both a usb-GPS and a autopilot connected at the same time correct?

Thanks, Steve

Steve,

How many usb-ports you have on your laptop? The setup that might work for you, selelct the usb port that has the AIS connected to, select AIS shared in the gps setting and select your other usb port for the autopilot.

Steve...
GPS, AIS or autopilot can be on any COM port and can be connected at the same time. What currently can't be done is having AIS and autopilot on the same port. It would also usually make little sense as AIS is running at 38400 bauds while autopilots usually want 4800. Having a USB GPS puck and autopilot on the same port is also hardly imaginable as you would not be able to do the wiring (the USB to serial converter is integrated into the GPS puck). In your situation, the solution probably is to get another USB to serial converter/cable (and in case there are not enough USB ports on your machine also an external USB hub) to connect to the autopilot.

Thanks Pavel, The more i research this I think you have found the solution. I was hoping to only use one serial > usb cord but if this works it will be fine!
