It's not a bad thing to be talking about it here. When Shell hooked up the 240V she toasted a bunch of items on the computer side of things but only took out the RS485 receive chip on the Mega60. The chip was socketed and easy to swap out. IF she'd been using an isolated dmx dongle at the time she wouldn't have killed the dongle and motherboard like she did. Isolated DMX lines save heartache and they deserve a mention all over the place.
