About This Guide

This guide contains detailed information and best practice recommendations about cabling, programming, and configuring the MLC 52 Series MediaLink Controllers and provides specifications and dimensions.

Throughout this guide the MLC 52 controllers are interchangeably referred to as “MLC 52,”

“MLC,” or “controller.”

About the MLC 52 Series MediaLink Controllers

The MLC 52 Series enable RS-232 or infrared (IR) remote control of a projector or other display device. They are economical, compact (one-gang or two-gang size), easy-to-use controllers for use with audio/video equipment in sites such as elementary or high school classrooms or small conference rooms. The MLC 52 acts as a universal remote control panel, providing control of the power, input selection, volume, and other functions of a display device. Device control is provided via the MLC front panel buttons or via a host computer or control system using RS-232 communication and the Extron Simple Instruction Set ™ (SIS ™ ) commands or the Extron MLC 52/DVCM 50 Configuration Program.

The MLC 52 can be configured using three different methods: z z z

The cabling, operation, and setup are identical for all MLC 52 models. All have the same button functionality.

Standard Features

z z

IR and RS-232 ports for universal display device control — The MLC 52 has a dedicated port for communicating with virtually any projector or display via infrared signal. The MLC 52 RS models also have ports for unidirectional RS-232 wired serial control. Projector control drivers can be downloaded from the Extron website

(

www.extron.com

) or can be created using the MLC 52 configuration program.

Discrete On and Off display device power controls — These controls simplify system operations and eliminate the need for a handheld display or projector remote control.

z z

Configurable, backlit buttons — The front panel buttons can be set up to control display device power, volume, input selection, or any other IR or RS-232 command function supported by the device. The buttons are backlit and can be custom labeled, offering easy operation in low-light environments.

Macro and toggle button modes — Each button on the MLC can be programmed to send out up to four IR or serial commands. You can set each button to issue all its commands with one press (macro mode) or to issue its commands one at a time, in sequence, with each button press (toggle mode). z z z

Front panel configuration port — This RS-232 serial port enables advanced configuration, driver downloads, and firmware updates to be performed from the front panel without the need to remove the controller from its mounting. The optional

Extron configuration cable (part number 70-335-01) can be used to connect the

MLC 52 to the RS-232 port of the computer.

Three configuration methods — The MLC 52 can be configured easily using the following methods: z z

IR learning — Allows the MLC 52 to be set up directly from the remote control of the display device without the need for software.

IR data transfer — Duplicates complete configuration information from one

MLC 52 model to another without cables or software.

z

Configuration software — Combined with one of the many IR or RS-232 drivers that are provided with the controller on DVD or available on the Extron web site, the Extron MLC 52 Configuration Program provides fast and simple setup.

Inactivity timer for display shutoff — Adjustable timer control provides automatic shutdown of the display device to conserve energy, prevent plasma burn-in, and extend projector lamp life.


z z z z z

Front panel security lockout — Front panel lockout (executive mode) can be implemented where the MLC 52 is installed in an unsecured environment and universal access is not desirable.

Flexible mounting options — With a standard electrical box or one of the included mounting brackets (“mud rings”), the MLC 52 can be mounted in a variety of locations, including walls and lecterns.

Volume control (VC) faceplates — The two-gang sized VC models each have a volume control knob in addition to the six control buttons. To use this knob, connect the MLC 52 to a power amplifier (purchased separately), such as the Extron MPA

Series Mini Power Amplifier that is also connected to the projector or display (see the

application diagrams

, later in this section). The volume control knob adjusts the volume on the amplifier. This option frees the two volume control buttons on the MLC to be used or reconfigured for other display device functions.

Section 508 Compliant — The MLC 52 meets or exceeds accessibility standards for Electronic Information Technology. For more information about the Extron Commitment to Accessibility, see the Extron Accessibility web page at

www.extron.com/company/article.aspx?id=accessibility

.

Power supply — A 12 V, 1 A, external universal ENERGY STAR

® qualified power supply, part number 70-775-01, is included and provides worldwide compatibility, low power consumption, and reduced operating costs.

NOTE: The Extron PS 124 and other Extron power supplies can also be used with the MLC 52.

Options and Accessories

z

MPA Series Mini Power Amplifier — Connect an MPA 152 (part number

60-844-01) to the volume control port of the MLC 52 VC models, and to your projector or display and speakers. This enables you to use the MLC volume knob to control the volume of the speakers via the MPA. z

Remote control — The optional IR 452 Remote Control and the optional IR Link and

IRL 20 signal repeaters provide infrared remote control of the MLC unit from up to

30 feet (9.1 m) away. The signal repeaters work with any Extron hand-held IR remote control.

MLC 52 Configuration Software

The included MLC 52/DVCM 50 Configuration Program is used to configure the MLC buttons and ports via an RS-232 connection. This software, provided on a DVD that is delivered with the product, enables you to set functions for the front panel buttons and to configure the MLC ports in order to control devices via the MLC. The software works in combination with the IR or RS-232 drivers, also provided with the MLC on DVD or at

www.extron.com

. See “

Installing the Software from the DVD

” in the “Serial

Configuration” section to access this program.


Device Drivers

In order for the MLC 52 to control a switcher, projector, or other display device via IR or

RS-232 communication, it must have drivers loaded for the devices it will control. Drivers can be obtained in the following ways: z z

IR or an RS-232 driver files can be installed from a disc, downloaded from the Extron web site (

www.extron.com

), or downloaded from Extron via the driver subscription feature within the MLC 52 configuration program. The drivers are saved on your computer in a folder located at C:\Program Files\Extron\Driver2. You can then upload the desired drivers to the MLC via the MLC 52 configuration software.

IR commands can be captured from the IR remote control of a device through

IR Learning or IR data transfer to create a driver. When a driver is created, it can be added to the configuration program so that the commands can be used to configure

the MLC to control the device (see “

Configuring the MLC 52 Using IR

” in the

“Installation and Configuration” section).

a

IR Learner/Transmitter — These sensors allow for IR control of the MLC and for

IR Learning. The two LEDs (one for transmitting, one for receiving) send and receive IR signals, enabling the MLC to learn commands and clone configurations from another

MLC 52. The IR remote control must be pointed directly at these LEDs for best results.

The MLC can “learn” IR commands in order to control the display device. IR Learning of device control codes is necessary only if there are no RS-232 codes available for that device or if you need to customize the driver. See “

Configuring Using IR Learning

,”

later in this section, for the IR Learning procedure.

You can also perform IR learning via the MLC 52 configuration software. See the

MLC 52 Configuration Program help file for the procedure.

b

Enable Macro LED — The LED located immediately above or to the right of the four

green IR LEDs is labeled E, for Enable Macro. This LED lights amber when you place

a button in macro mode (see “

Setting Up Button Macros Using IR

,” later in this

section).

Switch 1: Enables IR learning.

Switch 2: Enables data transfer, such as cloning the current MLC configuration onto another MLC 52 (see “

Configuring Using IR Data Transfer (IR

Beaming)

,” later in this section).

Switch 3: Disables IR repeats during playback. For most applications, this switch is placed in the off position.

Switch 4 is not used. d

Volume control (VC models only) connector — Connect an amplifier such as the

Extron MPA 152 or a PoleVault switcher to this direct-insertion captive screw connector to enable the volume control knob on the MLC 52 VC front panel to raise and lower the volume on the display device via the amplifier or switcher.

NOTE: This port must be connected only to an Extron device such as a PoleVault

®

PVS switcher, an MP Series microphone-to-line preamplifier, or an MPA

Series audio amplifier. e

Display control and power connector — This shared six-pole, 3.5 mm captive screw connector is used for IR and RS-232 control of the display device and for DC power.

The MLC 52 can be programmed via IR by the following methods: z z

IR data transfer from an MLC 52 that has been configured

IR learning from your projector remote control


Configuring Using IR Data Transfer (IR Beaming)

You can configure your MLC 52 by transferring button configuration data to it from another configured MLC 52 via the two IR LEDs on the back panels of the MLCs. With this method, you replicate (clone) the other MLC configuration on your own unit without the use of software or cables.

The following transfers are allowed: z

From an RS model to another RS model z z

From an IR model to another IR model

From an IR model to an RS model

To transmit configuration data via IR, both the transferring and the receiving MLCs must be removed from the wall, electrical box, or furniture, and both must be powered on. The

MLC that is already configured can be powered by an external power supply, or it can share a power supply with the unit that will be configured.

4.

Hold the remote control of the display device between 4 and 14 inches (10 to 36 cm) away from the MLC and point it at the IR Transmit/Receive LEDs on the MLC. Within

5 seconds of pressing the MLC button (step 3), press the button on the remote whose function you want the selected MLC button to learn. When the IR command has been learned successfully, the IR learning LEDs blink in rapid progression from the top to the bottom, then back to the top.

NOTE: For repeating command codes, such as those that increment and decrement a function (for example, turning the volume up and down), hold the button on the projector remote control for at least 3 seconds.

If no IR command is detected within 5 seconds, the LEDs and the front panel button

time out and stop blinking. z

If the IR code was learned, the rear panel LEDs blink rapidly in succession from the top down, then back up to the top.

z

If the IR code was not learned, the rear panel LEDs blink in random order.

5.

If you do not want to program additional commands on the button, repeat steps 3 and 4 for the next button that you want to program.

If you want to program another command to the same button, press the button again

(you can program up to four commands on one button). The next IR learning LED on the rear panel begins flashing (for example, if you have already programmed two commands on this button, the third LED from the bottom flashes).

6.

When you are finished programming buttons on the MLC, set configuration switch 1 on the rear panel to Off (down).

7.

Press the buttons that you configured to verify that the commands you entered have been learned. If you have an IR Emitter connected on the IR output, it should blink

(see “

Wiring for IR Control

,” earlier in this section).

Removing IR Commands from a Button

If you want to delete a command that has been programmed onto a button, you must remove all the commands programmed to that button, as follows:

1.

While the MLC 52 is powered on, set configuration switch 1 to On (up).

2.

Press the button for which you want to delete commands, then within 2 seconds press the same button again. The IR learning LEDs turn off.

3.

Verify that all commands were erased from the button by pressing the same button again. If the commands have been erased, only LED 1 (the bottom LED) blinks; the other LEDs remain off.

4.

When finished removing commands, set switch 1 to Off (down).

Setting Up Button Macros Using IR

Buttons function in either toggle mode or macro mode. By default, all the buttons

(except the On and Off Display buttons) are in toggle mode. This means that each press of the button issues one command — the next in sequence of the four commands programmed to the button (each button can store up to four commands).

In macro mode, a single press of a button issues all the commands (up to four) that have been programmed on that button, in the order they were programmed, at 1.5-second intervals. An example of a button macro application would be turning on multiple projectors or displays by pressing one button, one time.


To program an IR macro for a button:

1.

Ensure that power is applied to the MLC 52.

2.

Set configuration switch 1 on the rear panel to On (up). All front panel buttons light dimly.

3.

Program the buttons with the desired commands. See “

Configuring Using IR

Data Transfer (IR Beaming)

” or “


,” earlier in this chapter, for programming procedures.

NOTE: You must program the commands onto the button prior to setting it for macro.

4.

To put the button in macro mode, press and hold it for 3 seconds. The orange LED on the back panel, labeled “E” (see figure 18) flashes rapidly five times, then turns off, indicating that the button is now configured for macro mode. Release the button. The next time that the button is pressed while configuration switch 1 is in On position, the orange “E” LED lights, indicating that the button is in macro mode.

To take a button out of macro mode, press and hold the button for 3 seconds. The orange “E” LED turns off.

5.

Set configuration switch 1 to Off. Verify that the commands have been properly learned by pressing the button you programmed. The commands should be issued in succession at 1.5-second intervals.

NOTE: A button is able to learn commands while in macro mode if any of its four command memory blocks are open (not yet programmed with a command).

Configuring a Single Button for Input Source Selection Using IR

If you want to use only one button to select your input sources, you must program the button with one command for each source (up to four). Only one button needs to learn IR commands; and it has enough memory blocks to learn four input selection commands. To use this programmed button to select an input, press it repeatedly to cycle through all the inputs until you reach the desired one.

To program a single button to select multiple inputs:

1.

Disconnect power from the MLC 52.

2.

To make the one programmed button easily recognizable, replace all but one of the input (Video, PC, DVD, and VCR) button labels with a provided Not Used label, or remove the input labels and leave the buttons blank.

3.

Apply power to the MLC.

4.

Set configuration switch 1 to On (up). The front panel buttons light dimly.

5.

Press the MLC button that will store the input selection IR codes. The button blinks for 5 seconds, during which time it is able to learn codes. On the rear panel, the first (bottom) IR learning LED starts flashing.) If a command is not entered within

5 seconds, the button and LED stop blinking, and you must press the button again to put it in back in learn mode.

6.

Within 5 seconds, press the display device remote control button from which the MLC button will learn the first input selection command. If the command has been learned successfully, the Learning LEDs on the rear panel blink in rapid progression from the top LED to the bottom, then back to the top.


7.

To program a second input selection command on the same button, press the button again. The button and the second rear panel IR learning LED begin to blink. On the remote control of your display device, press the next button whose function you want the MLC button to learn.

8.

Repeat the procedure described in steps 5 and 6 for additional commands you want to add to the button you are programming. Each MLC button can be programmed with up to four commands.

9.

When finished programming the input selection button, set rear panel DIP switch 1 to Off (down). Verify that the button has been programmed correctly by pressing it repeatedly to cycle through the inputs.

Setting Up an MLC 52 VC Model with an Extron Amplifier

If you have an MLC 52 IR VC or an MLC 52 RS VC model, it can be connected to an optional Extron amplifier, such as the MPA Power Amplifier Series, the MLP Preamplifier series, or a PoleVault ® PVS switcher. The dedicated volume control knob on the VC controllers controls the audio output of an Extron MPA 152 or MPA 401 power amplifier, an MP series preamplifier, or a PoleVault PVS switcher, to which speakers for the system are connected.

Wiring the VC Port

To set up this configuration, wire the volume control port to the amplifier as shown in the following diagram. Set up the volume control, following the instructions in the amplifier user guide.

NOTE: Audio is now controlled from the MPA instead of from the projector. For best results, ensure that the audio volume of the projector is set to maximum

(assuming that the monitor output for audio is variable).

Configuring the MLC 52 IR VC and MLC 52 RS VC Vol Buttons

By default, the MLC 52 has two buttons on the front panel programmed for volume control (Vol

>

and Vol

<

). However, on the MLC 52 VC models, these buttons are not needed for volume control and can be programmed for other uses. To reprogram the Vol buttons, you can use IR Learning (see “


,” earlier in this

section) or the MLC 52 configuration program (see the program help file).


After the system has been cabled, configured, and tested, the MLC can be installed in the wall or furniture. Follow the instructions appropriate to the mounting option you selected.

Preparing the Site

NOTE: The installation of the MLC 52 must conform to national and local electrical codes and to the equipment size requirements.

Installation using a UL listed wall box is recommended for most mounting options, but for US models a mounting bracket can be used instead. To cut a hole in the mounting surface for the controller, use the dimensions from one of the rough-in templates provided

under “

Templates for the MLC 52 and MLC 52 VC (US Models)


Information” section as a guide to measure and mark the hole. The templates provide measurements for installing the MLC with either an electrical box or a mounting bracket.

CAUTION: The templates are not to scale and are provided for reference only.


z z z z z

The standard US MLC 52 model includes a one-gang plastic faceplate, which can be installed on a standard one-gang US electrical box that is at least 1.75 inches deep.

Mounting brackets (“mud rings”) are also included.

The US MLC 52 VC model includes a two-gang plastic faceplate, which can be installed in a standard US two-gang electrical box. Mud rings are also included.

The MLC 52 EU and MLC 52 VC EU models have 2-gang plastic or brushed aluminum faceplates that can be installed on standard two-gang European electrical boxes.

The standard MLC 52 MK model includes a one-gang plastic or brushed aluminum faceplate, which can be mounted on a 47 mm deep single MK electrical box.

The MLC 52 VC MK model includes a two-gang plastic or brushed aluminum faceplate, which can be mounted on a 47 mm deep double MK electrical box.

NOTE: EU and MK models must be mounted in an electrical box.

To prepare the site:

1.

Choose a location that will allow cable runs without interference. Allow enough depth for both the wall box and the cables. You may need to install the cables into the wall or furniture before installing the controller. If using an electrical box to wall mount the controller, locate a stud to which the box will be attached.

2.

Measure and mark the portion to be cut out of the mounting surface.

For US models, use the appropriate template and faceplate dimensions provided

“

Templates for MLC 52 and MLC 52 VC (US Models)


Information” section as a guide to measure and mark the area to cut out. If you are using a mounting bracket, see the template that came with the bracket.

3.

Cut out the opening in the wall or furniture.

Mounting the MLC to an Electrical Box

You can mount the MLC 52 in an electrical box or a mounting bracket. (For information

on mounting the electrical box itself, see “


” in the

“Reference Information” section. To attach a mounting bracket to a wall or furniture, see the instructions provided with the bracket.)

CAUTION:

If using an electrical box, ensure that it is grounded properly.

1.

If you want to install a different faceplate, attach the MLC to the desired faceplate using the provided screws (see “


,” earlier in this section).

2.

Disconnect power at the source and connect all cables to the MLC.

3.

Insert the MLC into the wall or furniture.


4.

Secure the MLC to the wall box or mounting bracket with the provided machine screws (as shown in the following illustrations), or attach it directly to the furniture with wood or metal screws.

NOTES: If the MLC (and the IR Link, if applicable) is not mounted to a grounded metal wall box:

• Ground each faceplate directly to an earth ground, or

• Tie each faceplate to its circuit board and power supply via a ground

pin on one of the connectors.

Do not tie a product faceplate to both a separate earth ground and the circuit ground (via a connector pin). If you tie a product to two different ground sources, you may introduce ground loops or other groundingrelated problems into the system.

Wall opening is flush with edge of box.

Selecting Inputs

Operating the MLC 52 Using IR Remote Control

Resetting

Locking the Front Panel (Executive Mode)


The MLC 52 front panel contains six buttons, each of which can be programmed with up

to four IR or RS-232 commands or functions. It also contains a configuration port, through which the MLC 52 can be connected to the RS-232 port on a computer to program the

MLC buttons, update firmware, and save the current MLC configuration to the computer hard drive.

The MLC 52 VC models each have an integrated volume control knob. On these models, the two buttons normally used for volume control on the standard MLC 52 models can be programmed to control additional outputs or other projector or display functions.

Buttons on the Front Panel

The front panel backlit buttons light amber when the MLC 52 is powered on. Buttons that are not currently selected and active are lit more dimly (25 percent brightness) than the selected ones (100 percent brightness).

When the MLC is delivered, the buttons are labeled. (You can relabel them by replacing the labels with others provided with the MLC (see “


” in the

“Installation and Configuration” section). You can program commands onto these buttons

(up to four commands per button) using IR Learning, the MLC 52 configuration software via the configuration port, or IR data transfer from a configured MLC 52.

Switch modes

Depending on the driver that you load to your MLC (see “

Loading Extron Drivers

” in the “Serial Communication” section), each of the buttons is preconfigured in one of the following switch modes: z z

Single switch mode: In this mode, the button operates independently of the other buttons. Pressing a button in this mode does not affect any other button.

Input mode: Buttons in this mode are grouped together so that only one of them can be active at a time. When one button is pressed and activated, it becomes fully lit, while the other (inactive) buttons are dimmed to 25% brightness. When you press one of the buttons on the front panel that are in input mode, all other buttons in input mode become inactive.

z

Volume mode: This mode is available only on the standard (not VC) MLC models, and only for the two buttons that are labeled Vol

>

and Vol

<

. When an RS-232 driver that contains a volume table is part of the configuration, pressing a button in volume mode accesses the volume table of the driver. Press and hold the appropriate button to raise or lower the volume of the projector or display by the amount specified in the volume table. When the MLC is in volume mode, the button labeled Vol

>

always increases the volume; Vol

<

lowers it.

of the volume button has no effect. You must press and hold the button to increase or decrease the volume.

Display power buttons — The display power buttons turn power to the projector or display on and off. Because the display device can be only on or off at a given time, these buttons are programmed in an exclusive switch group. (A 2-second hold requirement can be enabled or disabled via the configuration software; see the configuration program help file for the procedure.) b

Input selection buttons — These buttons are preprogrammed to select input sources. By default, they are in input mode; that is, only one of them can be selected at a time. If you want these buttons to operate independently of each other, use the

MLC 52 configuration software to remove the group configuration from them.

c

Configuration port — Connect this port to your computer RS-232 port to configure and communicate with the MLC. Through this port, the MLC receives commands issued via the configuration software on your computer.


Use a 2.5 mm TRS to 9-pin D-sub connector cable to connect the MLC to your PC via this 2.5 mm female TRS connector.

NOTE: This cable is an optional accessory that can be ordered from Extron (part number 70-335-01).

d

Volume adjustment buttons — (Standard MLC 52 models only) These two buttons are used to adjust the volume of the projector or display up and down.

If your A/V system does not require the volume up and down function (for example, if the MLC is configured with the VC faceplate containing the volume control knob), you can reprogram these buttons for input selection or additional display device functions

(see the MLC 52 configuration program help file for reprogramming instructions).

e

Volume control knob — (MLC 52 VC models only) The volume control knob on the

VC models enables you to adjust the volume of the display device via an Extron device such as an MPA series power amplifier, an MP series preamplifier, or a PoleVault PVS switcher.

NOTE: Use only Extron devices with this port.

Powering the Display Device On and Off

The display power On and Off buttons on the MLC 52 front panel are used to turn the projector or other display device on and off.

Powering On

Press and release the MLC 52 On button to power on the display device. The On button blinks for 4 seconds, then remains steadily lit.


Powering Off

To turn the projector or display off, press the Off button. The button blinks for 4 seconds, then remains off.

NOTE: A 2-second hold feature, requiring you to press and hold the Off button for

2 seconds in order to turn off the display device, helps prevent accidental powering off of the projector or display. This feature can be disabled and enabled through the configuration software. See the MLC 52 Configuration

Program help file for further information.

Selecting Inputs

The four buttons below the On and Off buttons on the front panel can be configured to select inputs on the display device. The PC and Video buttons have been preconfigured to select inputs — a desktop or laptop computer (PC); a VCR or DVD (Video).

Using IR learning, IR data transfer, or the MLC 52 configuration software, you can reconfigure these buttons and add commands to them to select other inputs if desired.

The two volume (Vol) buttons on the standard MLC can be configured to select inputs as well, if you do not need them to control projector or display volume. Up to four commands can be programmed on any button. See the MLC 52 Configuration Program help file for information on configuring MLC buttons.

Input Selection Buttons on the MLC 52 Front Panel

To select an input, press and release the appropriate input selection button. The command that was programmed in the first memory block of the button is executed. z

All buttons are lit at 25% intensity while the MLC receives power. A selected (active) input button lights more brightly than the other buttons. z z

If there is more than one input selection command programmed in the button memory blocks, you can execute the commands in memory blocks 2, 3, and 4 by pressing the button a second, third, and fourth time.

For example, if you have programmed memory block 1 on the Video button for a

VCR, and block 2 for a DVD player, you would press and release the Video button once to select the input to which the VCR is connected on the display, then a second time to select the DVD input. (Pressing it a third time reselects the VCR, and so on.)

If an input selection button is in macro mode, pressing the button once executes all the commands stored on that button, in memory block order (the command in

memory block 1 is performed first, then block 2, and so on). See “

Setting Up Button

Macros Using IR

” in the “Installation and Configuration” section.


Operating the MLC 52 Using IR Remote Control

The optional hand-held IR 452 remote control sends infrared signals to an MLC 52 via an optional IR Link or IRL 20. In conjunction with the MLC 52, it can be used to operate your projector, display, and input devices. The remote control is configured with commands for a variety of device functions (for example, VCR On, VCR Off, Stop, and Pause).

These commands can be programmed onto the MLC buttons only via the configuration software. (See the configuration program help file.)

NOTES: The IR 452 cannot perform the volume knob function on the MLC 52 IR VC or the MLC 52 RS VC. All other functions on the IR 452 are available on the

MLC 52 VC models.

Setup operations cannot be performed from the IR 452 remote control.

The IR 452 remote control requires the optional IR Link or IRL 20 in order to send commands to the MLC, which in turn issues the commands to the input or output devices.

1.

Wire the IR Link or IRL 20 to the MLC 52 and mount it. (See “


” or

“


” in the “Installation and Configuration” section for instructions.

See the IR Link or the IRL 20 user guide for mounting instructions.)

2.

Using the MLC 52 configuration software, program the desired buttons on the

IR 452 with the commands available with the currently loaded driver. (See the

MLC 52/DVCM 50 Configuration Program help file for the procedure.)

3.

To operate a device using the IR 452 with the MLC, point the remote control directly at the IR Link or IRL 20 signal pickup window.

4.

The IR 452 has a range of approximately

30 feet (12 m) within 40 degrees on either side of the axis (see the illustration at right).

Buttons on the IR 452 Remote Control

The buttons on the optional IR 452 Remote Control duplicate the MLC 52 front panel controls for normal operation. The MLC responds to commands from the

IR 452 as if the corresponding button were pressed on the controller.

The IR 452 Display Power On and Power Off buttons and the VCR and DVD control buttons cannot control a device through the MLC until commands have been stored in the MLC memory. The IR 452 VCR buttons control the first (lowest address numbered) VCR connected to the MLC, while the DVD buttons control the first (lowest address numbered) DVD connected to the MLC.

Commands are transmitted from the MLC control connector (via hard wiring) and IR ports (via IR emitters) when the corresponding button is pressed on the IR 452 or on the controller front panel.

Locking the Front Panel (Executive Mode)

To prevent access by unauthorized users, or accidental presses of the button issuing unwanted commands to devices, the front panel controls can be locked using executive mode. When the MLC 52 is in executive mode, all front panel functions are locked, so that pressing the buttons has no effect.

If a button is pressed while the MLC 52 is in executive mode, all the front panel buttons blink, indicating that the front panel is locked.

To place the MLC in executive mode:

1.

Power off the display device. Executive mode cannot be enabled if the device is on.

2.

On the standard MLC 52 models, press and hold the Vol

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.

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 on the following pages.

z z

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: z

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; RGB2, the desktop PC.) z

Projector remote control type B: One remote control button is used for all video formats (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.

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.

MLC 52 MediaLink Controllers • Special Applications 37

Projector remote control type A (application 1)

This remote control has a discrete button for each input. Two buttons are designated for

RGB inputs, one for S-video, and one for video (composite). z

Use IR learning to program the command from each of the projector remote control

RGB input selection buttons onto the MLC PC button.

z

Use IR learning to program the commands from the projector remote control Video and S-video buttons onto the MLC Video or blank (VC models) button.

(See “


” in the “Installation and Configuration” section

for the IR learning procedure.)

The MLC now has two commands each on the PC and Video or blank (VC models) buttons. This enables you to switch between the two PC inputs by repeatedly pressing the PC button, and between the two composite/S-video inputs by repeatedly pressing the

Video or blank button.

Control Type B


Programming buttons for multiple inputs on an RS-232 controlled system

If the MLC 52 RS will control the projector via RS-232, the projector remote control does not need to be involved. Program the MLC buttons directly via the front panel configuration port using the configuration software (see the configuration program help file for instructions on programming RS-232 commands to MLC buttons).

1.

Program commands 1 and 2 on the PC and Video buttons with the projector RS-232 command for discrete input selection.

2.

The MLC now has two commands each on the PC and Video buttons. Press these buttons repeatedly to switch between the two input selection commands that you entered on each button.

Application 2: Controlling Projectors that Require Power Off

Confirmation

Some projectors controlled via IR require the Power Off button on the hand-held remote control to be pressed twice to turn off the projector. These projectors usually present a prompt (similar to the one shown below) on the image, instructing you to press the Power

Off button again to confirm your intent to power off the projector. (If the projector is controlled via RS-232, this prompt is usually not displayed.)

Turn Power OFF?

“E,” flashes rapidly five times, then turns off, indicating that the button is now configured for macro mode.

5.

Set configuration DIP switch 1 on the MLC rear panel to Off (down).

Now, with one press of the MLC Off button, you can issue the command to projector off and respond to the projector confirmation prompt. The commands are issued in succession at 1.5-second intervals.

Application 3: Controlling Projectors that have Multi-coded IR

Functionality

Certain projectors, such as Philips projectors, have multiple IR codes for the same function.

Projectors with multi-coded IR functionality issue two commands for each IR remote control button. Command “A” is initiated by the first press of the button; command “B” is initiated by the second press. Because the buttons on the MLC 52 can store up to four commands, it is ideal for projectors of this type.

If controlled via RS-232, projectors that have multi-coded IR functions typically have a specific RS-232 command that selects or performs each desired function. Therefore, there is no command “A” or “B” for RS-232 control.

Configuring the MLC 52 for Multi-coded IR Functionality

This section provides instructions for using IR learning to program multiple input selection commands onto the MLC 52 buttons from two common types of hand-held projector remote controls that have multi-coded IR functionality.

NOTE: For best results, select a projector that has a dedicated audio and video input for each source used in the system. Video and audio should not share an input.

Loading Extron Drivers

Extron drivers are control files (libraries) of Extron-created projector or display commands that are specific to a particular display device. There are different sets of drivers for serial

(RS-232) and for IR control.

Before you can use the software to configure the MLC buttons, the IR, serial, or both driver packages must be loaded onto your computer. You must then load the driver for your display device to the MLC in order to configure the MLC to control the device.

NOTES: The MLC 52 is compatible with IP Link IR drivers found in the IPL Driver

Package, version 6 or higher.

Use preconfigured control files (drivers) whenever possible. If no driver is available for the display that you want to control, it is possible to create your own driver via IR Learning (see “

Configuring Using IR Learning”

in the

“Installation and Configuration” section) or using the MLC 52 configuration program (see the configuration program help file).

CAUTION: Loading a new driver causes the existing configuration on the MLC to be overwritten. If you know that you will want to use the previous configuration again, be sure to save it when the screen prompts you.

Loading the serial (RS-232) drivers

When you install your MLC 52 configuration software, the installation program loads the Extron serial drivers onto your computer at the following location, unless you specify otherwise:

By default, the drivers that you download are stored in the Driver2 folder on your computer at: z z

Windows XP — C:\Documents and Settings\All Users\Shared

Documents\Extron\ Driver2

Windows 7 and Vista — C:\Users\Public\Documents\Extron\Driver2

RS-232 drivers must be loaded or selected before you can choose RS-232 commands to program the buttons. (See the MLC 52 configuration program help file for more information.)


Downloading IR drivers from the DVD

The software DVD provided with the MLC 52 contains a set of device drivers that are also available from the web. To load the drivers from the DVD to your computer:

Using SIS Commands

Simple Instruction Set (SIS) commands can be entered on your computer, using a utility such as Extron DataViewer or HyperTerminal, to find out more information about the

MLC 52.

Host-to-Controller Communications

SIS commands consist of strings of one or more characters per field. No special characters are required to begin or end a command sequence. When the MLC determines that a command is valid, it executes the command and sends a response to the host device.

Most responses from the MLC 52 to the host end with a carriage return and a line feed

(CR/LF = ]), which signals the end of the response character string.

Controller-initiated messages

When a local event such as a front panel button press takes place, the MLC 52 responds by sending a message to the host, indicating what selection was entered. No response is required from the host.

The MLC sends the following copyright message only when it first powers on.

(c) Copyright 2005, Extron Electronics, MLC 52, Vx.xx, 60-100n-nn where Vx.xx is the firmware version number and n is the MLC 52 model number.

Error Responses

If the MLC 52 is unable to execute a command it receives because the command is invalid or contains invalid parameters, the controller returns an error response to the host. This response consists of the letter “E” followed by a number and a carriage return with a line feed. The following error response codes can be returned:

E10 – Invalid command or parameter

E14 – Not valid for this configuration

Using the Command/Response Table

The command/response table on the following pages lists valid ASCII command codes, the responses of the MLC to the host, and a description of the command function or the results of executing the command. The ASCII to Hex Conversion Table below is for use with the command/response table.

If you want to install the MLC 52 or MLC 52 VC (US models) in an electrical box (in a wall or in furniture), install the box as described below.

NOTE: These instructions are for US models only. To mount an electrical box for an EU or MK model, follow the directions provided with the box by its manufacturer.

1.

See the appropriate template diagram in “

Templates for MLC 52 and

MLC 52 VC (US Models)

,” later in this section, to find out the dimensions of the opening required for the size of the wall box that you are using. If you are using a mud ring with the wall box, see the templates provided with the bracket.

2.

Using a ruler or tape measure and a soft pencil, draw guidelines on the installation surface (wall or furniture) in the desired orientation and location where the opening for the bracket or wall box will be cut.

CAUTION: The template diagrams in this guide are not to scale. Do not trace them or use them as patterns on the installation surface. Use these diagrams only for reference to obtain the dimensions of the hole that needs to be cut. Use a ruler to measure and draw the cutting guidelines.

3.

Cut out the wall or furniture material inside the marked area.

4.

Check the opening size by inserting the wall box or mounting bracket into the opening. The equipment should fit easily into the opening. Enlarge or smooth the edges of the opening if needed.

5.

Feed cables through the electrical box punch-out holes, and secure them with cable clamps to provide strain relief.

6.

Exposed cable shields (braided or foil) are potential sources of short circuits. Trim back or insulate shields with heat shrink.

WARNING: To prevent short circuits, cut back the outer foil shield to the point where the cable exits the cable clamp. Both braided and foil shields should be connected to an equipment ground at the other end of the cable.


7.

Insert the electrical box into the opening, and attach it to the wall stud or furniture with nails or screws, leaving the front edge flush with the outer wall or furniture surface. The following illustration applies to all sizes of electrical boxes.

Wall Stud

Cable

Cable Clamp

Screws or Nails

Wall opening flush with edge of box

Figure 54.

Attaching an Electrical Box to a Wall Stud

z z z

If you are attaching the wall box to wood, use four #8 or #10 screws or 10-penny nails. A minimum of ½ inch (1.3 cm) of screw threads must penetrate the wood.

If you are attaching the wall box to metal studs or furniture, use four #8 or #10 self-tapping sheet metal screws or machine bolts with matching nuts.

If you are using a mounting bracket (mud ring) with the electrical box, follow the directions included with the bracket to attach the clips that fasten the bracket to the wall or furniture.

8.

If desired, replace the faceplate or button labels on the MLC. (See “

Replacing the

Faceplate (US Models Only)

” or “


” in the “Installation

and Configuration” section.)

9.

Cable and test the MLC before fastening it into the wall box, mounting bracket, or furniture.


Templates for MLC 52 and MLC 52 VC (US Models)

Use these rough-in templates as guides to measure and mark the hole in the wall or furniture through which the MLC 52 will be mounted. The templates provide measurements for installing the controller with either an electrical box or a mounting bracket. (You do not need the templates if you are mounting the panel using an external mounting option.)

NOTE: These templates are for US models only.

The MLC controller requires a depth of at least 1.25 inches (3.2 cm) inside the wall or furniture.

CAUTIONS: These templates are not to scale and are provided for reference only.

If you use a wall box or mud ring, connect it to an earth ground. If you do not use a grounded wall box or mud ring, ground the faceplate to an earth ground, or tie it to the circuit ground via a ground pin on the circuit board.
