Special Applications
This chapter describes some special types of applications that represent unique
conditions. For the MLC 52 to operate properly in these situations, it is important
that the controller be configured correctly. On the following pages, three
application examples are described, along with their requirements for the MLC 52.
Application 1: Using Multiple Sources with an MLC 52
Following is an example of an application in which the system contains more than
two inputs. This system has two PC inputs (a laptop and a desktop) and two video
inputs (a VCR and a DVD).

Application 1: Projector with more than two inputs
For best results, a projector that has dedicated audio and video input connectors for
each PC and each video source should be chosen. Do not use a projector on which
multiple video inputs share one audio input.

IR control:
If the projector is to be controlled by the MLC 52 using IR, its IR
remote control will have 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’s label (e.g., the RGB1
button may select the laptop computer; RGB2, the desktop PC.)
Projector remote control type B:
One remote control button is used for
each video format (RGB, S-video, and/or 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. See chapter 5, S
erial
Communication
, for procedures for RS-232 programming.
