wired multi-projector remote - sanyo projector

We have three projectors in the church.
There are two in the front, one as a nominator on the wall in the back).
Since they are all Sanyo projectors, our chief technicians have set up a system that allows us to control them from the media booth.
Since the projectors all use the same remote control, simply turn on one of them and weld a small headphone jack to the location where one of the infrared LEDs is connected to the board.
There are wires from the media booth to every projector.
At the end of the media Booth of The Wire there is a headphone plug for connecting to the remote control, at the other end of each projector, an infrared LED is installed behind the projector so that it can shine to the remote receiver.
Since these are installed on the ceiling, I don't have a photo.
The original plan was to connect each wire to the remote control when the projector needed to be turned on or off, but in order to lift it to a higher level, the technician built a small switch box.
Basically, this is a five-position switch that connects the contacts entered by the remote control to the wire of the projector (s)at the:1. rear2. left front3. right front4. front (both)5.
