Thanks, Paul. If the module only supports one way communication, then that's obviously not going to work.

I have a DSC security panel and will likely buy the Envisalink 4 to add networking capability to it. I haven't found any way online to connect a DSC system to the ISY994 other than DSC Link which requires a running computer 24/7. The Envisalink API is available online (http://forum.eyez-on.com/FORUM/download/file.php?id=194&sid=9c65577d45a7eda163feab0810be0da0). I'm an okay programmer but definitely not an expert. It looks like a fairly simple TCP connection to send commands and receive status information from the panel. I saw that there is a Networking module for the ISY994. Would it be possible to write code to link the two via this module? I don't own an ISY994 yet so I am somewhat unfamiliar with how programming it works. How difficult would that be to do? Are there any drawbacks to doing it this way? Thanks
