Hi,
We've got a vantage pro2 weather station hooked up via USB to a linux box with a 2.6.15 kernel.
We can see and query the vpro2 machine via vpconfig, but we're seeing the above record over and over, and no historical records are coming in (although we are getting regular input, it appears.)
Hrm, right now I'm getting this:
| Quote: | [root@xxxxxx wview]# /usr/local/bin/vpconfig /dev/ttyUSB0 show
vpifGetRXCheck failed - aborting
|
hrm...well, when it was working we were getting | Quote: | Mar 30 11:08:50 ubcfarm wviewd[5659]: <1284429449> : vproRunState: retrying arch
ive record...
|
and not getting any archive records.
Help! |

Serial interface is not right. USB-to-serial convertors/drivers do not all work properly - you didn't mention which one you have. I have great success with a generic (ebay) PL-2303 based convertor. The CP2101 seems to work pretty well (Mac version of WL comes with this).
One guy about a month ago was having problems with a Keyspan and switched to a PL-2303 chip and became very happy.
I cannot stress this enough (but it has been noted several times before):
vpconfig is a first-line test, it does not prove the serial interface is good. The VP protocol is a mixture of ASCII and binary and vpconfig does not prove compliance. Not being able to obtain archive records is a tell-tale sign of a bad serial interface.

It's not a serial-to-USB, it's a direct USB (I believe).
Thanks for the response! |

This might not be relevant, but I get the 'vpifGetRXCheck failed - aborting ' message if I run vpconfig whilst wview is running, i.e. if the port is already in use.

The VP USB interface data logger has a CP2101 USB-to-Serial chip inside the data logger module. It is in fact logically no different from having a serial VP and using your own USB-to-Serial convertor. It still requires a USB-to-Serial adapter driver for windows or unix.
