Adding Extra VGA connector to Dell 3400MP Projector

Since M1-DA to VGA cable is quite expensive, we have decided to add extra connector to our Dell 3400MP Projector so we could just use common male to male VGA cable.

1st thing to do is to know the connector pin-out. For VGA connector we have 15-pin connector.

Cable = MALE and Projector = FEMALE.

Next, the M1-A connector (AKA M1-P&D Plug) A lot of pin. :-)

Cable = MALE and Projector = FEMALE.

Internet research tell me that only 7 connections are needed in order to make this work as below
