Sorry I haven't responded sooner but the Ethernet crossover cable just arrived in the mail however I am still unable to get into the administrative console. Any further suggestions?

Pretty sure it was 255.255.0.0

I recently started having some issues with lighting commands not firing with my ElkM1G panel. I was messing around in the ISY99i console and merely changed the internet (I believe subnet mask). Now after exiting the console I can't seem to get back into it. Help would be appreciated.

I have several KeypadLink's and I would like to program a single button on each to turn on/off all outside lights to be used in a emergency situation. Is there a way to do so? I get hung up on naming responder/controller exactly what is the difference? Embarrassed for having to ask.
