Data download problem with WMR200

Hi All,

I have the same problem. Everything was working with the betas (e.g. 1006) but with 1017 I started getting this error. I may be a little unique in that I'm running the Cumulus workstation as a Windows XP virtual machine on ESXi 3.5. Since ESXi doesn't allow USB connections (or serial for that matter) I have an SIIG USB over IP 1-Port USB server to present the USB port as a network device.

I've attached the log.

I moved your post from the thread you posted in, as you don't have a Fine Offset station.

Your station isn't playing nicely. It says it has a history packet available, but when Cumulus asks for it, it doesn't send it; instead it sends a temperature packet and a wind packet, and then a packet with a CRC error, and then goes quiet. Some sort of communication problem, I guess.

Okay, I'll check on the USB over IP software and the device to see if there is anything "quirky" happening. There was a few .NET framework patches that came down that might have impacted the USB driver software.

I'll post an update.

Hmmm... Seems to be working now but I had to revert to Cumulus 1.9.2 Build 1006.

I'm also seeing in the logs the following:
10/7/2011 09:48:25.235 : WMR200: Out of sync; discarding

I'm also seeing a fair number of this type of errors:

I am getting the data now without any errors or drops.

Any ideas?

Mike

The 'out of sync' and 'Invalid CRC' messages are both indications that Cumulus is receiving garbage data.

Hmmm... I'll have to get another (better) USB over IP adaptor and see if that changes anything. I've also changed the host software to see if anything changed but no luck.
