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?

  • \$\begingroup\$ why do you need the pinout of the 24pin plug? .... do you have a connector that plugs in? \$\endgroup\$ – jsotola Mar 20 at 4:59
  • \$\begingroup\$ Sorry for the late reply. I do have one input cable, it connects from an iphone dock connector (the old one) to the device. I'm not sure if the video formats outputted by the old iphones/ipads are composite (what I want). \$\endgroup\$ – Owen Chiu Mar 24 at 2:55
