Has anybody integrated an Epson EB-2155W projector using a network connection successfully? It has SDDP but as soon as the projector is turned off, the network is no longer detected so it doesn't receiver the on command. Any ideas how to get around this? 

Should be a setting within the menu of the projector.  Communication on Power Off, I believe is the term.  You need to select yes, and then serial and network stay alive when powered off.

I'm going by other Epson models I've dealt with and not that particular one, mind you.
