As long as you tell us what projector you are using with this we will program the RS232 for you and supply a lead or around 2M from the breakout box to a serial female to connect to your projector.
Power to the breakout box in the ceiling means no unsightly plug reducing voltage that has to go into the back of a dado trunking and less chance of the users turning off the power by mistake. Power to the panel is via the supplied 10m long RJ45lead.
Programming yourself: You may download the software free of charge from the download link below. It is very easy to input any RS232 codes you wish.
If you want to use the closed contact option with any other make of screen then this will work as we can supply a lead with the common, drop and retract marked for easy connection. If you have a screen with four core wire and wish to connect to this then you can buy a Sapphire RFR packs to replace the control box on your screen. It will then work with our system.
