Help! VirtualVP V1.2.3 hanging "Could not read archive page nn"
« on: December 13, 2009, 06:07:24 AM »
It started a bit ago.. the connection to the Davis VP1 console (serial -> Belkin serial/USB port) would suddenly stop working.  It thought it might be my B&B 9POP4 serial optoisolator, but that's been replaced.

On startup of VirtualVP 1.2.3, the 'Reading Archive data' screen pops up, indicates 96% reception, has 5 bars filled in, and just stops.   I've deleted the archiveCache.dat and archiveCache.dat.tmp files, with the same result.

Also tested with WeatherLink directly connected (not through VirtualVP) and it reads the datalogger fine.

The log.txt for VirtualVP shows

Just the obvious questions, not that I can help but might assist with trouble shooting.

What OS
Virus Scanner running?

What happens if you clear the VP data logger?

Windows XP Pro SP3 latest patches
AV - McAffee

It seems that direct connect from WeatherLink 5.9.0 to the station also fails after a while with a 'Computer gave up waiting for a response from the station.  Check port settings and connections."

This happens with or without the optoisolator installed.  Without the optoisolator, I get a 112/114 mph wind reading due to a ground-loop .. hence the need for the 9POP4 optoisolator :)

I'm wondering if the datalogger in the VP could be failing somehow.. it is 5 yrs old and has been in continuous service.
I'm lothe to just reset the datalogger (thereby causing a 'hole' in my WD data), but I'd appreciate any other guidance folks may have.

I'm still using VP 1.1.4  Guess I am behind a bit.

All you need is Time, Aptitude and Desire ... and you can build just about anything...

I would try a complete power down and removal of the data logger for a while
to reset it

when re powering it up, then you will need to set the time/date, 1 minute logging interval

yes you will then miss data for that period of time though

also try just running WD , i.e not through virtualvp, as a test?

has the console had a firmware update recently?

The 5.9.0 version of WeatherLink seems to have much tighter timeout values. The error WeatherLink is showing is what it shows when it keeps timing out. If both WeatherLink and VVP are having communication issues talking to the datalogger, I would look first at your connections. You probably know the routine, but try unplugging and replugging both ends of the serial connectors several times.

I'm not familiar with the optoisolator. Is that a new addition, or have you had that on and had everything working before?

Did this start with v.1.2.3?

I would try a few things before resetting the archive and losing that data.

Can you email me a copy of the archiveCache.dat file?

I spent a fair amount of time trying to accomodate WeatherLink 5.9's less forgiving timeouts, and had it working well in my tests, so I thought I had succeeded. There are a few things you can try. One is trying 5.9.1, a beta version of WeatherLink that is supposed to fix some of the problems in 5.9.0. Another is to try configuring WeatherLink to talk to VirtualVP via IP instead of a com port. In my testing it seemed that WeatherLink allowed much more generous timeouts for IP connections than for serial connections. The third, though admittedly less desirable thing to try is running the previous version of WeatherLink (5.8.x) which doesn't seem to have the timeout issue.

Hi Steve

I unistall all and reinstall again. It the beginning seemed Ok but after some tasks started again.

Espesially when i use Toms WXSIM weather programm. In away creates a problem to Virtual VP.

But i guess not only his software.  I guess that maybe any programm that runs behind it and the performance of the cpu goes very high..or if at the same time you do other work also

In my other pc in a remote location , i have just the alert about ...VPconsole Far too long since last loop 5,531 last command Live sensor data....but other than that it works ok. In that pc i am running also 3 web cameras with the Blue Iris software and the CPUs performance is high also

On the other hand maybe its not very convinient just to have a pc dedicate for weather also.

Maybe you can find a away so Virtual VP wont hang up so easily...

Thanks

Nikolas
