<p class="MsoNormal">*nod* ... correct, I knew that when I bought it, but didn't think this all the way through (as usual!!!). I do have a URI and URIx but really liked the repeater maker interface so I picked one (along with others) up at Dayton this year
to give them a try. <o:p></o:p></p>

<p class="MsoNormal">What I'd like to do is drive a relay board to switch a fan on if the receiver is active or there is traffic coming in to the node, being connected to another station or hub for example. I read over the GPIO and event management subsystem
documentation, and it looks like that's what I need, but I don't have a parallel port nor can I tap the GPIO's on my interface easily (or even know if they can be used as per the above). <o:p></o:p></p>
