Hello,
I recently installed Virtual VP v 1.1.2.15 Beta (I had thought I was downloading the “stable” version, but that’s not what I got when I clicked on that link), and the N8VBvCOM driver. VVP seemed to connect to my Davis Vantage Pro 2 weather station module just fine (it showed that it was downloading data from it). But when I tried to connect my Weather Link software (v. 5.7) to VVP (port 6,7, 8, or 9), I got a message saying “Weather Link tried to open a Com Port that doesn’t exist on this system. Please examine your Com Port settings”.
I’m not having any luck investigating this problem. A search of Windows Help doesn’t yield much of anything that’s relevant. I wondered if maybe there’s a conflict with Windows Firewall, though I didn’t receive any error message that Windows Firewall had blocked anything. I thought about trying to create a port exception in Widows Firewall, but Serial port wasn’t a choice for type of port to configure (only UDP or TCP).
Actually, after I posted the question about my difficulty with VVP, I did download the more recent version of the program, but it didn’t make any difference.
The Davis interface is via USB port. It uses comport 4. I don’t have enough much of an understanding of ports like this, but when I first opened Weather Link, there was an option for it to automatically detect the weather module, and it “found” it on comport 4.
It’s hard to say without getting more detailed information, but my first suggestion would be to uninstall and then reinstall the N8VBvCOM driver. To get a better understanding of what could be causing the problem, I would need to see the log.txt file. In windowsXP, it’s in the VirtualVP folder. In Vista, it’s buried under the Users/{username}/AppData folder hierarchy. If you can email me that log.txt file, that would help.
