Worked with Mike, via e-mail to isolate the problem. It turns out that I have a defective unit. When cycling the power (rebooting) none of the lights on the unit ever come on (tx, rx, etc). I have contacted Smarthome for a RMA number to return for replacement. Thanks to all of you that replied.
I would also like to thank Mike for such a quick response the PM tha I sent him. He had the trouble isolated in about 3 emails and about 20 minutes total. I guess it was a wise choice to get the ISY. One of the main reasons I opted for one was because of all that I had read about the excellent tech support.
I will post again when I get my replacement.
Thanks again,
Wayne
