Erik,
I'm taking a stab in the dark here. But you probably have to tell the WXT5
to provide output in the format you want which I assume is ASCII and it's
currently set to NMEA 0183.
Check the
manual
https://www.vaisala.com/sites/default/files/documents/WXT530-User-Guide-in-English-M211840EN-E.pdf
Page 157.
- Problem
Data messages are not
in expected format.
- Possible causes
The communication protocol may not be the one you want.
- Action(s)
Check the communication
protocol of the device by using the
Vaisala Configuration Tool or any
terminal with command aXU,M!
(SDI-12) aXU,M<cr><lf> (ASCII/
NMEA) and change it if needed
Hope this helps you. I used to these issues when I was surveying cable.
