Hmm I have several sites where we have various VPL projectors that are hooked up 232 (because we need the user picture position presets for aspect ratio settings), and they are also connected ethernet for OVRC monitoring and FW updates. Havent seen the control break on any of them. Using the VW1000ES 1.0 module as well but I see we also changed the polling in it to poll only the necessary items, as it has tons of useless polling in it that just isnt needed.?
