Vaisala WXT520 connection


khkim Feb 17, 2010 01:01 AM

Hi,

I have a Vaisala WXT520. In order to connect with CR10X, I am trying to program using Edlog 32 in LoggerNET with reference a manual, 'http://www.campbellsci.com/documents/manuals/wxt520.pdf'

But, I could not connect WXT520 with CR10X. Would you please check my CSI code.

Thanks for your support.

The following code is the CR10X program.

I suspect it is a configuration or timing problem. One easy thing to try is slowing down your execution interval to 15 seconds.

How do you have the WXT520 configured? Check its address, that it is SDI enabled and what the update intervals are.

Check wiring. Is the brown wire in 12V and not SW 12V?

Let us know what you find.
