We have a couple of 4100MPs and are looking for the correct cable to use the 12V relay interface to control our powered screens.  Our screen vendor got us the 12V relay modules for our screens but the cable that is supposed to go to the projector is just two bare wires.

 

Does Dell sell a cable with the correct connector for the 12V interface or is there a doc with the spec (connector size and pinout) so that we can get one made?

 

Thanks!
