I have been given a Microvision Showwx+ projector which I would like to hook up to a video source. Mine only came with the Dock connector, so it will not work with any modern video outputs.
I know that there were cables manufactured for this product that accept composite and VGA signals.
The connector on the device appears to be a Optoma Technology Universal (24pin) (pictured here https://static.bhphoto.com/images/images500x500/Optoma_Technology_BC_PK3AVGX_Universal_24pin_to_VGA_1278082015000_699641.jpg )
I have been unable to find a wiring diagram/pinout for this connector. Any advice on how to go about figuring out which wires are carrying video signals?
