Hi,

With différent versions)

Somtimes thé PC restart alone...

I don't havé this problem with other application like ls viewer or sirfdemo

Only with Opencpn any one havé an idea ?

You are not alone. OpenCpn has had this problem for years, and no one has been able to figure out how to fix it. My solution was to run windows XP on my nav computers.

How....

Thank for you reply i Will try..
Did you now if this issue is with version of seven?

I started a thread on this topic about 1-2 years ago which ran to more than 100 posts. There wasn't an internal solution, ie changes to Windows or OpenCpn settings that worked.

But XPort, a freeware com port redirection program easily solved the problem. Google it up and dowload it. Redirect your current port to something unused like Com 1. Then set OpenCpn to com 1 and you will have a solid connection.

You have to rerun XPort after each reboot, but it is a small inconventience that really works.

Check your power saving settings for the com port, in Control Panel's Hardware Manager

Sorry but where is this settings ?

[SailFastTri]

START|CONTROL PANEL| choose POWER OPTIONS|for whatever plan you are using, choose CHANGE PLAN SETTINGS|choose CHANGE ADVANCED POWER SETTINGS| explore the tree to see if your USB ports are set to suspend, and change it so they don't.

You will find the same **** in Windows 8 (Eight) but obviously the default settings are not set to supend USB. At last it is so in the Win8 preview I have seen.
Normally an operating system is not allowed to shut down a device as long as traffic is seen on the device. But these tiny-soft people in Redmond knows nothing about operating systems...

I've tryed all your solution :
Xport and USB port power, for each it's working more longer ! 4h vs 20mn. So it's better but not ok....

Now i try with xport, usb power disabled and running opencpn in xp compatibility and with admin right (a lot of problem with vista and seven becom from permission problems...). I've started opencpn like that just now, i'll post the result in few hours...

David i don't find your thread about that? could you please post the link
thanks
