Introduction

About this Manual

This manual contains information about the Extron IR 452 hand-held infrared remote control and instructions on using it to control the MLC 52, the MLC 104, and the DVCM 50.

The terms "IR 452" and "remote control" are used interchangeably in this manual.

About the IR 452

The Extron IR 452 is a hand-held remote control that is used in conjunction with the Extron IRL 20 or the IR Link to control the MLC 52 MediaLink Controller or the DVCM 50 DVD/VCR Control Module, via infrared (IR) signals.

Communicating through the DVCM 50, the IR 452 can also control the MLC 104 via the IRL 20 or the IR Link. The IR 452 sends IR commands to the DVCM 50, which passes the commands on to the MLC 104 in serial form as Simple Instruction Set (SIS ™) commands.

Features

MLC 52 and DVCM 50 control — Provides IR remote control

of the MLC 52 MediaLink Controller and the DVCM 50 Control Module via the IR Link or IRL 20.

MLC 104 control — Provides IR remote control of the MLC 104

MediaLink Controller when used with the DVCM 50 control module and the IR Link or IRL 20.

DVD and VCR control — Provides IR remote control of a VCR

and DVD player when used with the DVCM 50.

Buttons — The IR 452 front panel contains buttons that

are equivalent to the buttons on the MLC 52 and the DVCM 50. These buttons can initiate all the functions available on the control modules.

Additional adhesive-backed button labels are provided,

enabling you to change the names of the buttons on the IR 452 overlay to match the way the buttons are labeled on the MLC 52 or MLC 104.

Using the IR 452

Setup and Operation

Operational Overview

The IR 452 can control the MLC 52 or the DVCM 50. It can also control the MLC 104 via the DVCM 50.

Button conﬁ guration on the control modules cannot

be performed from the IR 452. The commands must be programmed on the MLC 52 or DVCM 50 using the Windows-based conﬁ guration software or IR Learning.

Each button on the IR 452 front panel, when pressed, sends an IR signal to the IR Link or IRL 20 signal repeater. The IR Link or IRL 20 relays the signal to the MLC 52 or the DVCM 50. The IR signal activates the equivalent button on the MLC 52 or DVCM 50, causing the button to perform the function that was programmed to it (e.g., turning the projector on and off, selecting an input, or turning the projector volume up and down).

If an MLC 104 is connected to the DVCM 50, the signal sent from the IR 452 goes to the DVCM, which issues the appropriate

™

command to the MLC 104. The SIS command activates the

SIS appropriate button on the MLC 104, which communicates the command to the display device via RS-232.

Setting Up

Before you can use the IR 452 remote to control the MLC 52, the DVCM 50, or the MLC 104, you must do the following:

Program the buttons on the MLC 52 or the MLC 104

and/or the DVCM 50 with the commands you want them to issue. Refer to the appropriate product user's manual for programming procedures.

Make any needed changes to the button labels on the MLC

controller and/or the DVCM, if you have programmed any buttons to have functions different from their pre-installed labels.

Wire and install the MLC 52 or the MLC 104; the

DVCM 50, if applicable; and the IR Link or the IRL 20, following the directions in the appropriate product user's manual.

Enabling control of the MLC 104

The MLC 104 can be controlled by the IR 452 via the DVCM 50 in conjunction with the IR Link or IRL 20. To set up the MLC 104 for control by the IR 452, do the following:

1. Program the buttons on the MLC 104 and the DVCM 50

front panels with the desired commands. (Refer to the product user's manuals for programming instructions.)

2. Connect the DVCM 50 rear panel host port to the MLC 104

rear panel host port. (Refer to the DVCM 50 User's Manual for instructions and diagrams.)

3. Connect the IR Link to the DVCM 50 rear panel. (Refer to

the DVCM 50 User's Manual for instructions.)

4. Mount the MLC 104, the DVCM 50, and the IR Link or

IRL 20 on a wall or furniture as desired. (Refer to the mounting instructions in the product user's manuals.)

Changing button labels

You can use the Windows-based conﬁ guration software to program the buttons on the MLC 52 and DVCM 50 to be used for functions other than the pre-labeled ones. For example, you might want to use the two MLC 52 buttons that are pre-labeled Vo l  and Vol  for additional input selections or for Auto Image, instead of volume control.

To program the MLC 104 buttons, use the Global

Conﬁ gurator 2 (GC2) software. Visit the Extron Web site at www.extron.com for information on ordering this software.

If you reprogram an MLC or DVCM button for a function different from what its label indicates, you should also relabel that button to reﬂ ect its new function. When you relabel an MLC or DVCM button, you will also need to relabel its equivalent IR 452 button to match it.

With the IR 452, you receive a set of adhesive-backed labels, which you can use to relabel IR 452 buttons as needed. The ﬁ gure on the next page shows the button labels that are provided.

Afﬁ x the provided button labels to the IR 452 overlay

as needed to match the buttons on the MLC and/or the DVCM. (See Changing button labels, later in this chapter.)

Install the two provided AAA batteries in the IR 452. (See

Installing the batteries, later in this chapter.)

In order for the IR 452 to be able to control the MLC 52 or the DVCM 50, you must use the Windows®-based conﬁ guration software or IR Learning to program the MLC 52 or DVCM buttons with the functions for which their buttons are labeled. Refer to the product user's manual for button labeling information.

(You can program the buttons to perform functions other than those for which they are labeled. If you do this, you will need to relabel the buttons on the MLC and/or the DVCM, and on the IR 452, to reﬂ ect the programming.)

If you program the MLC 52 or DVCM buttons as labeled, pressing the equivalent IR 452 buttons issues the commands as described below.

Display power buttons — Pressing these two buttons sends IR

signals to the MLC 52 or MLC 104 (via the DVCM 50) to activate the buttons labeled On and Off.

When the MLC On and Off buttons are programmed as labeled, the IR 452 Power On and Power Off buttons turn the projector or other display device on and off.

Mute On and Mute Off buttons — These buttons are not

direct equivalents of any buttons on the MLC 52 or MLC 104. However, you can use your MLC's conﬁ guration software to program the MLC to mute and unmute the video and/or audio on the display device when these IR 452 Mute buttons are pressed.

When the DVCM 50 TV/VCR button is programmed as labeled, or the command is programmed to an MLC 52 memory block, pressing the IR 452 TV/VCR button switches the VCR between TV and VCR modes.

Channel button — Pressing the up- or down-arrow on this

rocker button sends an IR signal to either of the following:

•

The MLC 52 to activate the memory block to which the channel switch command has been programmed

•

The DVCM 50 to activate the buttons labeled Tuner

and .

The MLC 52 or DVCM 50 must be in VCR mode. If

they are in DVD mode, this button has no effect. See

Selecting DVD or VCR mode, later in this chapter.

When the DVCM 50 Tuner Up and Down buttons are programmed as labeled, or the command is programmed to

an MLC 52 memory block, the IR 452 Channel Up and Down

arrow button changes the TV channel to the next higher or

lower channel number.

Front Panel buttons — Pressing these buttons (located in the

Front Panel section of the IR 452) sends IR signals to the MLC 52 or to the MLC 104 with the DVCM 50, to activate the buttons on the MLC's front panel.

The following table shows the functions performed on the MLC 52 and the MLC 104 (with the DVCM 50) when the IR 452 Front Panel buttons are pressed (if the MLC buttons are programmed as pre-labeled).

DVD control buttons — When the DVCM or MLC 52 is in

DVD mode, pressing each of these buttons sends an IR signal to the DVCM 50 to activate its button with the same label, or to the MLC 52 to activate its memory block programmed with the button's command.

VCR control buttons — When the DVCM or MLC52 is in VCR

mode, pressing each of these buttons sends an IR signal to the DVCM 50 to activate its button with the same label, or to the MLC 52 to activate its memory block that has been programmed with the button's command.

DVD and VCR (mode selection) buttons — Pressing either of

these buttons sends an IR signal to the DVCM 50 to activate the equivalent mode selection button, or to the MLC 52 to activate its programmed memory block. This causes the DVCM or MLC 52 to switch to the selected mode.

For example, if you press the DVD button on the IR 452, the DVCM or MLC 52 switches to DVD mode. (If it is already in DVD mode, pressing the IR 452's DVD button has no effect.)

Selecting DVD or VCR mode

The DVD and VCR buttons on the IR 452 are different from its other buttons in that each contains a permanent mode switch command. This command is sent to the DVCM 50, which activates its equivalent button, or to the MLC 52, which activates its programmed memory block, every time the button is pressed. Regardless of any programming done to the DVD and VCR buttons on the DVCM 50, pressing these IR 452 buttons always causes the DVCM or MLC 52 to switch to the mode of the button that was pressed.

If the DVCM 50 or MLC 52 is in VCR mode and you press

• the IR 452's DVD button, the controller switches to DVD mode. (If it was already in DVD mode, no switch occurs.)

If the DVCM or MLC 52 is in DVD mode and you press

• the VCR button on the IR 452, the controller switches to VCR mode. (If it was in VCR mode, no switch occurs.)

If additional commands have been programmed on the

DVCM 50's DVD or VCR button, these commands also are issued when the IR 452 DVD/VCR button is pressed.

To issue a command from the IR 452 to a DVD player or a VCR, you must ﬁ rst press the button to select the appropriate operating mode, as described below.

Controlling the MLC 104

The IR 452 can control an MLC 104 through a DVCM 50 that is connected to the MLC rear panel host port.

Refer to the DVCM 50 User's Manual for wiring

instructions.

IR 452 to MLC 104 communication process

The following occurs when you press a button on the IR 452:

1. An IR signal goes from the button to the IR Link or IRL 20,

then to the DVCM.

2. The DVCM interprets the IR signal and responds to it by

sending the appropriate SIS command to the MLC 104.

You do not need to program any buttons on the

DVCM 50 for it to interpret the signals it receives from the IR 452.

Muting and unmuting

The MLC 104 does not have buttons that control muting and unmuting on the display device. However, you can program Mute On and Mute Off commands onto the MLC 104 using the Global Conﬁ gurator (GC2) software. (Visit the Extron Web site at www.extron.com for information on ordering the GC2 software.)

Depending on the feature set of your display device, you can program the MLC 104 to mute/unmute the video, audio, or both.

To use the IR 452 to control muting/unmuting, press the Mute On or Mute Off button in the Display section. Pressing these buttons causes the DVCM 50 to send an SIS command (1M for Mute On button or 0M for Mute Off button) to the MLC 104, causing it to mute or unmute the display device.

Volume control on the MLC 104

To control the volume on the MLC 104 using the IR 452, press the rocker button in the Display section. Pressing the up- or down-arrow on this button causes the DVCM 50 to send a +V or –V SIS command to the MLC 104, which responds by increasing or decreasing the volume on the display device.

Remove the Volume label from the sheet of labels provided with the IR 452, and afﬁ x it above the arrow rocker button on the IR 452 front panel as shown in the illustration below.

For example, the ﬁ rst row of the table above shows that when you press the Power On button in the Display section of the IR 452, the signal sent to the DVCM 50 is interpreted as the SIS command 1P. This command is sent to the MLC 104 to activate the button that is labeled On (in the Projector section). The MLC 104 responds by issuing the command to the projector to turn on.

Once you have programmed and labeled the buttons on

the MLC 104, you should relabel the IR 452 buttons to indicate the commands they will initiate on the MLC 104.
