this is from the NCD site: http://assets.controlanything.com/Software/labview/RelayDriver.vi maybe you can adapt this to what you need?  It looks very similar...

I suspect you need a termination character...

Hi, billko, 

where did you find the command set [254 108 0] to switch relays? I cannot find them. If you could provide the source, it will be greatly appreciated.

Sorry, I didn't get them from anywhere.  I wasn't the original poster.  I only provided a link to the communications VI.

I know this post was from last year, but did you resolve the issue? I am having the same issue. Trying to switch relays from LabVIEW, but don't know what command set to send to the WiFly by TCPIP.

If you were speaking to me, I wasn't the one with the problem.  I don't know if the original poster solved the issue or not.  There must be some documentation floating around on the internet somewhere - I hope!

Sorry i can't help you.

Maybe those two links will put you in the right direction.
