Extron electronic MLC 52 manual Programming Buttons for an IR Controlled System

The MLC 52 is configured differently depending on the type of projector remote control that will be used and on whether the MLC will use IR or RS-232 projector control. Because each button on the MLC 52 can store up to four commands per button, the PC and Video buttons should be programmed as shown in the illustrations below and on the following pages.

•IR control: If the projector will be controlled by the MLC 52 using IR, its IR remote control has one of the following types of button configurations for video selection:

•Projector remote control type A: A different remote control button is used for each video input source. Each button selects the input source with the signal type that matches the button label (for example, the RGB1 button might select the laptop computer while RGB2 selects the desktop PC.)

•Projector remote control type B: One remote control button is used for all video formats (RGB, S-video, and composite video). This type of button must be pressed repeatedly to toggle through all the inputs with the same format.

•RS-232 control: If the projector is to be controlled by the MLC 52 RS via RS-232 commands, the projector typically has a discrete (specific) command for selecting a particular video input. That is, the projector does not have an RS-232 command to toggle through its video inputs.

The illustrations on the following pages show the commands to program to the memory slots on the MLC input selection buttons from the two types of projector remote controls when the projector is controlled via IR. Determine which of these two types most resembles the hand-held remote control of your projector, then select the appropriate instruction set from the following sections to program IR commands to your MLC 52.
