a.Gather all the cables from the speakers, A/V wall plates, MLC 104 IP Plus controller, and any installed optional devices that have been run to the switcher location, and pull them down through the ceiling hole and the pipe. These cables are:

•the MLC power/RS-232 cable

•the CAT 5 input cables from the wall plates

•the speaker cables

•the MLC to projector (IR/RS-232 projector control) cable

•any optional device cables (e.g. Aux audio input Priority Page Sensor Kit, VoiceLift etc.)

c.Connect the output video signal cables (VGA and RCA) to the switcher and pull the loose ends down the pipe so that they hang out the pipe with the IR/RS-232 projector control cable. These cables connect to the projector later.

NDo not thread any high voltage power cabling, such as power supply or projector power cords, through the projector pipe. This violates National Electrical Code.
