Com port problems

Post by eivindcom » Mon 20 Feb 2017 10:44 pm


I am trying to make Cumulus MX work with a Davis VP2 with a Belfryboy USB clone. It runs for a few minutes, updates ok and seam to work. Then some COM port problems happens. I have attached the diganostic file, any ideas?

At the end it looks like an unauthorized error is thrown. Are you running the program as administrator?

The logger stops sending archive data, and then when MX tries again, this error occurs:

En enhet koblet til systemet virker ikke.

"A device attached to the system is not working."

So some kind of issue has occured with the logger or perhaps more likely, the USB adapter, as the next error is:

Ingen tilgang til porten. - No access to the port.

Hi Eivind,
did you solve this problem?
Is the BelfryBoy datalogger a stable solution?
