Applications
This section 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. In this section, three application examples are
described, along with their requirements for the MLC 52.
• Application 1: Using Multiple Sources with an MLC 52
• Application 2: Controlling Projectors that Require Power Off Confirmation
• Application 3: Controlling Projectors that Have Multi-coded IR Functionality
When setting up the front panel buttons for these applications, keep in mind the following:
• Switch modes: You can configure buttons to operate independently of each other
(single switch mode), or to function as a group (input mode). To set the button switch
mode, see Switch modes on page 27.
• IR command modes: In macro mode, one button press issues up to four
commands in succession at 1.5 intervals. In toggle mode, one button press issues
only one command. See Setting Up Button Macros Using IR on page 20 to set up
buttons using IR.
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).

Figure 29. Application 1: Projector with More Than Two Inputs
For best results, choose a projector that has dedicated audio and video input connectors
for each PC and each video source. Do not use a projector on which multiple video inputs
share one audio input.
