Alrighty, EISY is my only choice. That gives me something to look at and see what it can do.
As for the '994, I am willing to poke at it a bit and see if it will do anything. I know the ethernet switch it was connected to was killed in the strike, as was the 2413s. Another nearby device had its ethernet port fried, but worked otherwise.
Our 994 powers up, but the ethernet port never shows link or activity (like no cable connected). Replaced the ethernet cable to no avail. The lights on the 994 "look like normal on startup", but end up with power LED steady on, memory and error LED flashing at 1hz. I do have backups of the ISY settings. The replacement 2413s appears to be ok, except I can't get into the ISY to verify more than the PLMs LED comes on.
