About This Guide

This guide provides detailed information and best practice recommendations about cabling and conﬁguring the Extron® MLC 62 Series MediaLink Controllers, and reference information about speciﬁcations, dimensions, and programming of the controllers.

Throughout this guide the MLC 62 controllers are interchangeably referred to as “MLC 62,” “MLC,” or “controller.”

About the MLC 62 Series MediaLink Controllers

The Extron MLC 62 Series MediaLink Controllers are panels that control a wide range of audio/video systems in any classroom, meeting facility, or auditorium via RS-232 or IR control. They act as extended remote control panels, featuring eight (optionally six) labeled backlit buttons that can be conﬁgured to control power, input switching, and volume on a display device or switcher. If desired, you can replace these buttons with ones having different labels, which also are provided with the controller. The buttons can be conﬁgured via the MLC 62 Windows®-based conﬁguration software.

All models can control a projector, display, or switcher via IR. In addition, the MLC 62 RS models can control display devices, switchers, and various other items such as lights, a projector lift, or a motorized screen via RS-232, IR, relays, or digital input.

The MLC 62 controllers are housed in secure, compact, one-gang sized enclosures, which can be mounted on a wall or furniture, with or without an electrical junction box or mounting bracket.

MLC 62 Models

The MLC 62 Series MediaLink Controllers include the following models: MLC 62 IR D — US model. Controls devices by IR only; has a one-gang Decora® faceplate

and ﬁts in a one-gang US electrical box. MLC 62 RS D — US model. Controls devices by RS-232, IR, relays, and digital input; has a

one-gang Decora faceplate and ﬁts in a one-gang US electrical box. MLC 62 RS EU — European model. Controls devices by RS-232, IR, relays, and digital input;

has a one-gang Jung frame and ﬁts over a standard one-gang EU electrical box. MLC 62 RS MK — UK model. Controls devices by RS-232, IR, relays, and digital input; has a

standard MK sized frame and ﬁts into a standard one-gang MK electrical box.

Extron MLC 62 Series MediaLink Controllers • Introduction 1

The four MLC 62 models have the same button functionality and use the same conﬁguration software. All models can be controlled by pressing the front panel buttons or via a host device using RS-232 communication and simple ASCII commands (Simple Instruction Set, SIS™). They differ from each other in the following ways:

 The MLC 62 IR D rear panel does not contain the Relay, Digital Input, or RS-232

display ports that the RS models have.

 Some front, side, and rear panel connectors are located in different places on the

three RS models. (See “Panels and Connectors” in the “Features, Cabling, and Operation” section.)

Features

Some of the features of MLC 62 include:

 Customizable buttons — Eight buttons are standard on the MLC 62 and are

prelabeled for power on, power off, volume up, volume down, and input selections. An additional set of prelabeled buttons is included, enabling the controllers to be customized to suit the application.

 Button backlighting — The front panel buttons are backlit to facilitate use in

low-light environments.

 Alternative six-button conﬁguration — For applications in which only a single

function is necessary for an input device, the standard eight-button faceplate can be replaced with a six-button one. Each pair of source selection buttons can be changed to a long, single function button.

 IR and RS-232 ports — The MLC 62 RS models have a dedicated serial port for

communicating with most types of projectors or ﬂat panel displays via unidirectional RS-232. They also have an IR/S port, which enables IR or RS-232 control.

The MLC 62 IR D has only an IR port, which is used for IR communication only. IR and RS-232 display control drivers can be downloaded and used to conﬁgure the

controller.

 Relays (RS models) — Two relay ports enable control of room devices such as lights,

motorized screens, and projector lifts.

 Digital Input (RS models) — A Digital Input port enables monitoring of a switch or

sensor to control devices.

 IR Learning — The MLC 62 can be conﬁgured by IR learning, using the remote

control of a switcher or display device to create a driver that enables the MLC to control the device.

 Device drivers — A wide variety of Extron certiﬁed, ready-to-use device drivers are

available via the MLC 62 conﬁguration software, the provided MLC 62 software disk, and the Extron Web site (www.extron.com).

 USB conﬁguration port — The MLC 62 can be conﬁgured via a USB mini B port,

located on the rear or side panel (depending on the model). This port can also temporarily provide power to the MLC during conﬁguration.

 Volume adjustment buttons with LED level indication — Individual up and down

buttons for audio level control with ﬁve LEDs that indicate current audio settings.

 Macro capability — Each button can be conﬁgured to execute multiple actions

through the serial or IR control ports. For example, a button can be conﬁgured so that a single press triggers commands to

turn on a display, select the RGB input of the display, and trigger a relay.

 Toggling — Buttons can be placed in toggle mode, which adds ﬂexibility by enabling

two different sets of commands to be executed with alternating presses of the button.

 Built-in speaker — A speaker provides audible feedback when buttons are pressed

to conﬁrm user actions.

 Inactivity timer for display shutoff — An adjustable timer controls automatic

shutdown after a speciﬁed period of inactivity.

Extron MLC 62 MediaLink Controllers • Introduction 3

 Front panel security lockout — If the MLC 62 RS D is installed in an unsecured

environment where easy access is not desirable, a security lockout feature can be implemented to lock out all front panel controls.

 Activity LED — An LED on the MLC front panel lights red, green, or amber to

indicate button presses, the transfer of data, front panel lockout, and other actions.

 Section 508 Compliant — The MLC 62 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.

MLC 62 Conﬁguration Software

The included MLC 62 Conﬁguration Program is used to conﬁgure the MLC buttons and ports via an RS-232 or USB 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 Conﬁguration Software” in the “Software-

based Conﬁguration” section to access this program.

Device Drivers

The MLC 62 can control a switcher, projector, or other display device via IR or RS-232 communication. The MLC must have drivers loaded for the devices it will control in order to send commands to those devices. Drivers can be obtained in the following ways:

 IR or an RS-232 driver ﬁles can be installed from a disk, downloaded from the Extron

Web site (www.extron.com), or downloaded from Extron via the driver subscription feature within the Windows-based conﬁguration program. The drivers are saved on your computer in a folder located at C:\Program Files\Extron\Driver2. You can upload the desired drivers to the MLC via the MLC 62 conﬁguration software.

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

IR Learning via the MLC 62 conﬁguration program to create a driver that the MLC can use. 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 Using IR Learning” in the “Software-based Conﬁguration” section.)

Features

Activity LED — This bicolored LED lights green when the MLC front panel buttons

are pressed. It lights red while the front panel is disabled (executive mode) and blinks red while the display device is powering up and down.

Display power On and Off buttons — After conﬁguring these buttons, use them

to turn the connected display device or switcher on and off. The face of the On button contains a nub, which helps you to identify the button by touch. When the On button is pressed, it blinks rapidly while the connected device is warming up. When the Off button is pressed, it blinks slowly while the device is cooling down. When this delay period has elapsed, the power button that was pressed remains brightly lit.

By default, only one of these two buttons can be selected (active) at once. Using the

MLC 62 conﬁguration software, you can associate other functions and relays with each of these buttons.

Volume buttons and LEDs — Use these buttons to adjust the audio volume. Each

Volume button flashes when pressed and continues to flash while being held. The volume indicator LEDs above the buttons give indications of change to the volume

level as follows:

 When the RS-232 or IR/S port has been conﬁgured with a serial driver that

contains a volume table, the ﬁve LEDs light in order from left to right to show volume level increments.

 If the current driver does not contain a volume table, the ﬁrst two LEDs on the left

blink each time the Volume Down button is pressed, and the last two LEDs on the right blink each time the Volume Up button is pressed, indicating a volume level decrement or increment.

Extron MLC 62 MediaLink Controllers • Features, Installation, and Operation 10

Input selection buttons — These buttons can be used to select the desired audio

or video input for the connected device or for a variety of other functions. By default they are set up as follows:

 RS models: Three of these buttons are set to input mode, meaning that they are

a mutually exclusive group — only one of the buttons can be selected at a time. The selected button lights brightly and remains lit when selected. All other input buttons remain dimly lit. The fourth button, labeled Mute, is set in Toggle mode and is not grouped with the others.

 MLC 62 IR D: Two double-sized buttons are grouped in input mode and are

mutually exclusive.

This button behavior can be changed via the conﬁguration software. See “Setting

the button modes” in the “Software-based Conﬁguration” section or refer to the

MLC 62 conﬁguration program help ﬁle, for more information.

Reset LED — Indicates the status of a reset in progress.

Reset button — Press this reset button to initiate factory ﬁrmware or conﬁguration

resets. (See “Resetting the MLC 62 Using the Reset Button,” later in this section.)

USB conﬁguration port — Connect a USB cable (USB A to mini B) between

your computer and this port to conﬁgure the MLC via the conﬁguration software and to update the ﬁrmware. This port can also provide power to the MLC during conﬁguration.

NOTE: Do not use this port as the permanent power source for the MLC. It

should be used for power only during button and port conﬁguration.

 On the MLC 62 D models, the USB port is located at the right edge of the front

panel behind the wallplate. To access this port after installation, you must remove the wallplate from the unit.

 On the MLC 62 RS EU and MK, the USB port is located on the left side panel. To

access this port after installation, you must detach the MLC from the installation

h i

surface.

DIP switches — Reserved for future use

IR Learning sensor — This sensor enables the MLC to learn IR commands from the

hand-held remote control of a display device or switcher. The IR-learned commands are used to create an IR driver, then conﬁgured to be played back with any button press. See “IR Learning,” later in this section.

NOTE: Before performing IR Learning to create a driver, check to see if an Extron

driver exists for your device.

j On button Identiﬁcation nub — The face of the power On button contains a raised

nub that helps you to identify the On button by touch when lighting is dim.

Extron MLC 62 MediaLink Controllers • Features, Installation, and Operation 11

Buttons

The MLC 62 Series controllers have backlit, prelabeled buttons. The front panel button illumination provides status on what the MLC 62 is doing. The buttons are lit while the MLC has power. When a button has been pressed and is active or on, it lights brightly. While a button is inactive or off, it is lit dimly.

When buttons are grouped together, only the button that is pressed lights brightly. The other buttons in the group remain dim. (See “Setting the button modes” in the “Software-Based Conﬁguration” section for information on grouping buttons.)

The buttons can be removed and replaced with buttons with different labels. They can then be conﬁgured with the functions that their labels represent. See “Conﬁguring

the Front Panel Buttons” in the “Software-based Conﬁguration” section or refer to

the MLC 62 conﬁguration program help ﬁle for detailed procedures for conﬁguring the buttons.

Each Display On/Off and input selection button can be set up to perform a sequence of several functions, which can be combinations of the following options:

 A driver operation — Execute an RS-232 or IR control command that is part of a

device driver (for a projector, VCR, DVD player, switcher, and so forth)

 A relay operation — Execute a relay command to a room device such as a motorized

screen or a projector lift.

 Setting a time delay — Insert delays between executed commands.  Setting the button ﬂashing rate — Specify fast or slow ﬂashing of a front panel

button and the number of seconds the button ﬂashes.

NOTE: While a button is ﬂashing, all front panel buttons are disabled.

 A user-deﬁned RS-232 operation — Issue a non-driver-associated RS-232 command

(one that you programmed separately), such as an SIS command, via the IR/S or the RS-232 port.

 Button emulation — Initiate a series of button functions with a single press of a

button.

Extron MLC 62 MediaLink Controllers • Features, Installation, and Operation 20

Wiring the Digital Input Port (RS Models Only)

Two-position Switch

The Digital Input port on the MLC 62 rear panel lets you connect a switch or sensor to control other devices in the room that are connected to the MLC serial, IR, and relay ports. This port measures two states — high and low — of the connection between the switch or sensor and the connected device. The port accepts 0 to 24 VDC input. The threshold voltages are as follows: a voltage below 1.0 VDC is measured as logic low, and a voltage above 1.5 VDC is measured as logic high.

There is also an internal, +5 VDC, selectable, pull-up resistor for this circuit. If a connected device does not have its own power source and will be powered through the controller, conﬁgure this port (via the MLC 62 conﬁguration software) with Input with Pullup as the digital input mode. If the connected device provides its own power, select Input for the digital input mode. (See “Assigning commands to the Digital Input port” in the “Software-based Conﬁguration” section or refer to the MLC 62 conﬁguration program help ﬁle to select the digital input mode.)

In addition, you can program actions on this port, so that each time a high or low state is detected, one or more functions are performed. An example of this is front panel lockout, or executive mode. (See “Locking the front panel from the Digital Input port” or refer to the conﬁguration software help ﬁle to conﬁgure the Digital Input port.

The Host/Conﬁg port provides an alternative connection by which the MLC 62 can be conﬁgured and controlled from a host device or computer. (The primary means of conﬁguring the MLC is through the USB port; see “Conﬁguring the MLC via the USB

Port,” later in this section.) In addition, SIS commands can be issued through this port

from the computer to control the MLC (see the “SIS Control” section). The RS-232 protocol for this connection is 9600 baud, 1 stop bit, no parity, 8 data bits, no

ﬂow control. Use a female 9-pin to bare wire RS-232 cable or a universal control cable (UC 50',

UC 100', or UC 200') to connect a Windows-based PC or an RS-232 control system to the MLC via this 3-pole, 3.5 mm captive screw connector as follows:

1. Wire the RS-232 cable to one of the 3-pin captive screw plugs provided with the

MLC 62, as follows:

 Receive wire to pin 1, which plugs into the Tx (transmit) port  Transmit wire to pin 2, which plugs into the Rx (receive) port

 Ground wire to pin 3, which plugs into the _ (ground) port

Mounting the MLC 62 EU in a Raceway Using Spacers (Optional)

If you are experiencing difﬁculty with the MLC 62 EU staying in place when installed in a cable raceway, this may be due to a gap between the metal mounting bracket and the wall frame.

When this gap exists, the tabs on the sides of the MLC do not reach the metal mounting bracket and the MLC does not snap completely into the wall frame.

You can remedy this situation by installing a spacer (provided with the MLC 62 EU) between the metal mounting bracket and the rim of the junction box. This spacer appears very similar to the metal mounting bracket, except that it has holes instead of slots for the mounting screws, it is engraved with the words “Optional Spacer” and “Place behind bracket,” and has a slightly larger center opening than the mounting bracket.

NOTE: Do not attempt to use the spacer in place of the metal mounting bracket.

Because of its larger opening, the spacer will not hold the MLC 62 EU in place in the wall frame.

To mount the MLC 62 EU to a raceway using the spacer:

1. Mount the electrical box in the raceway.

2. Attach the spacer to the electrical box using two of the included screws in the holes

at the top and bottom of the spacer. Leave the screw heads protruding approximately 1/8 inch from the surface of the spacer.

Extron MLC 62 MediaLink Controllers • Features, Installation, and Operation 29

3. With the “Front” label toward you, place the metal mounting bracket onto the spacer

Creating an MLC 62 Conﬁguration — Getting Started

To use the MLC 62 to control devices, you must create one or more conﬁgurations for it, using the MLC 62 conﬁguration program. A conﬁguration is a set of speciﬁcations for button command assignments and port parameters that enable the MLC 62 to control your display device or switcher.

After you have downloaded and installed the software and device drivers, perform the procedures described on the following pages to create MLC conﬁgurations.

NOTE: Conﬁgurations can be created away from the job site and without the MLC

being connected to the computer.

Overview of Steps to Create a Conﬁguration

This section lists the major steps to creating a conﬁguration. The procedures for each step are described later in this section. For more details of each procedure, refer to the MLC 62 conﬁguration program help ﬁle.

Start a new project. To get started using the MLC 62, you need to start a new

project, to which you will add one or more conﬁgurations for your MLC. See “Starting a New Project,” below.

Conﬁgure the IR and/or serial ports. See “Conﬁguring the IR and Serial Ports.”

Conﬁgure the front panel buttons. See “Conﬁguring the Front Panel Buttons.”

Set up relays, if desired. See “Adding relays to buttons.”

Conﬁgure the Digital Input port, if desired. See “Conﬁguring the Digital Input

Port.”

Save and upload the conﬁguration to the MLC. See “Uploading a

Conﬁguration to the MLC.”

Starting a New Project

An MLC 62 project is a ﬁle (with a .mlp extension) that contains port and button conﬁgurations for one or more MLC 62s. A conﬁguration must be created within a new or existing project. A project can be saved, copied, and edited (for example, by adding or changing conﬁgurations within it). You can also create a conﬁguration and add it to an existing project.

You can start a new project either when ﬁrst opening the MLC 62 software or while the software is open and another project is active.

NOTE: Only one project can be active at a time. Opening a new project closes the

current one.

1. Open the MLC software by selecting the MLC icon from the Start menu your

computer desktop. By default, the software is located at All Programs\Extron Electronics\MLC 62\MLC 62. The Start Options window opens in front of the MLC 62 window.

2. On the Start Options window, select the Create a New Project radio button.

3. Click OK. The Add Device dialog box opens.

conﬁgurations, organize them, and save them all as a single project ﬁle.

bThe Front Panel tab enables you to conﬁgure the buttons and assign all

commands to them.

Extron MLC 62 MediaLink Controllers • Software-based Conﬁguration 45

The following is displayed on the MLC 62 window:

 The device conﬁguration name appears in the conﬁguration tree in the left pane,

with the names of the two ports (“Display” and “Serial” or “IR”) to which a device can be connected and controlled via IR or RS-232.

 The Front Panel tab is displayed in the main section of the window and contains

a diagram representing the front panel of your selected MLC. (If this tab appears blank when opened, click on the name of the MLC device conﬁguration in the left pane to display it.)

NOTE: For identiﬁcation purposes, the buttons in the diagram are numbered

1 through 8, from left to right in each row. When two buttons are combined into one, as in the six-button conﬁguration, their identiﬁcation numbers are combined as well. In this manual, a combined button is identiﬁed by both numbers; for example, when buttons 5 and 6 are merged, they become button 5/6.

 In the title bar, the project name is shown as “Unnamed Project*.” (The asterisk

following the name indicates that the project has not been saved since changes were made.)

7. Save and name your project as follows:

a. From the File menu, select Save As... .

b. On the Save As window, give your project ﬁle a name and save it to the desired

location on your computer.

NOTE: Your project is saved as a ﬁle with the extension .mlp.

8. Proceed to conﬁgure the MLC buttons and ports as described in the following

sections.

Extron MLC 62 MediaLink Controllers • Software-based Conﬁguration 46

Conﬁguring the IR and Serial Ports

The MLC 62 can control devices or switchers via two rear panel ports (the IR/S and RS-232 ports) on the RS models or via one port (the IR port) on the MLC 62 IR D. Use the MLC 62 conﬁguration program to add the desired drivers to each IR or serial port to which a device (for example, your display or switcher) is connected.

To conﬁgure a port, follow these steps and refer to the illustration below.

1. If you have not already done so, download the drivers for the devices you will be

connecting to the MLC.

2. On the device conﬁguration tree on the MLC 62 window, select the port to

which your device will be connected (ports are listed below the names of their conﬁgurations).

For RS models, it is recommended that you start with the Display port (labeled “RS-232” on the rear panel).

When you click on a port name, the Port Conﬁguration screen is displayed in the right section of the MLC 62 window. You can also click the Port Configuration tab to display it.

Figure 51. Port Conﬁguration Tab

Extron MLC 62 MediaLink Controllers • Software-based Conﬁguration 47

3. RS models only: (Optional) If you selected Serial Port (representing the IR/S port

on the rear panel) in step 2 and want to conﬁgure the IR/S port for IR, select IR Port from the Port Type drop-down menu. When you select the IR Port option, Serial Port changes to IR Port on the device conﬁguration tree.

NOTE: If the device conﬁguration you are creating is for IR only or if you selected

Display Port (representing the RS-232 port on the rear panel) from the device conﬁguration tree, the Port Type menu is unavailable.

If you selected the Serial (IR/S) port in step 2, the Port Type menu has two options: IR Port and Serial Port. (Serial Port is the default.) If you will be using IR communication with the device connected to the IR/S port, select IR Port from this menu. When you select the IR Port option, Serial Port changes to IR Port on the conﬁguration tree.

4. (Optional) Set the driver display ﬁlters. If you want to display only a selected portion of

the available drivers, set ﬁlters for this ﬁeld by making selections from the drop-down menus in the Driver Filters section:

 Device Type — Select the type of device the MLC will control from the port

being conﬁgured (for example, DVD, switcher, or Video Projector). Only drivers of the selected type are displayed in the Available Drivers ﬁeld. Select Any Device Type to display all device types for which you have drivers.

 Manufacturer — Select the manufacturer of the device that will be connected

to the port (for example, 3M, Sony, or Leica). Only drivers made by the selected manufacturer are displayed in the Available Drivers ﬁeld. Select Any Manufacturer to display drivers from all manufacturers.

 Version — Select Latest Version to display only the latest version of device

drivers, or Any Version to display all versions of drivers. After you make each menu selection, all drivers downloaded in step 1 that meet

your selected criteria are displayed in the Available Drivers ﬁeld to the right.

5. In the Available Drivers window, select the driver for the device that will be connected

to the port.

6. Click Add Driver. The name of the selected device driver is displayed in the Added

Drivers ﬁeld. To delete a driver from the Added Drivers ﬁeld, select it in the ﬁeld, then click the

Remove Driver button.

NOTE: Only one driver can be added to a serial port. An IR-conﬁgured port may

have multiple drivers assigned.

7. Serial connection only: From the Baud Rate, Data Bits, and Parity drop-down

menus in the Serial Port ﬁeld, select the port parameters required by your device for connection to the MLC.

To obtain this information, if needed, click the View Comm Sheet button. A PDF document opens, giving information about the selected device driver. (The port conﬁguration information is on the last page under “Serial Communication.”)

NOTE: If Display Port was selected from the conﬁguration tree in step 2, these

parameters are automatically set.

8. If you have conﬁgured the port for IR, repeat steps 5 and 6 to add more IR drivers if

desired.

Conﬁguring the Front Panel Buttons

The Front Panel tab on the MLC 62 window enables you to conﬁgure the buttons on the MLC 62 front panel. By clicking on a button, then making selections from the available menus, ﬁelds, and sub-tabs on the Front Panel tab, you can conﬁgure the corresponding button on the MLC front panel.

Default button conﬁgurations

The MLC 62 conﬁguration software provides a default button conﬁguration, which is displayed in the diagram on the Front Panel tab when you ﬁrst open a new project. In this basic conﬁguration, the buttons in the diagram are labeled to match the physical buttons installed in the MLC at the factory. The screen buttons are also colored to indicate the grouping modes in which the front panel buttons are preset. Depending on the model you selected, the default conﬁguration contains some commands assigned to certain buttons.

Button modes, commands, and labels can be changed as desired to create new MLC 62 conﬁgurations. When you upload a conﬁguration to the MLC, the front panel buttons are grouped as speciﬁed and perform the commands assigned in the new conﬁguration.

Command types for the buttons

The following types of commands and functions can be added to the buttons via the sub-tabs on the Front Panel screen. Refer to the MLC 62 conﬁguration software help ﬁle for details on each type of command and the procedure for assigning it.

 Driver commands — The Driver sub-tab lets you specify the commands that will

be issued from the selected port (IR, IR/S, or RS-232) to the connected display device or switcher when the button is pressed on the front panel. (See “Assigning driver

commands to buttons” on the next page.)

 Relays — The Relay sub-tab lets you specify the relay commands that will be issued

from the Relay port(s) when the button is pressed. Devices connected to the Relay port could include a projector screen that is to be raised and lowered, room lights that are turned on and off, or a low-voltage controller (LVC) to which a device is connected. (See “Adding relays to buttons,” later in this section.)

 Time delays — The Time Delay sub-tab lets you insert a delay of a speciﬁed

number of seconds between functions when multiple commands have been assigned to the button. You can set the amount of seconds that the MLC waits after issuing a command before it issues the next one. The delay period can be from 0.5 to 90 seconds in 0.5 second increments.

 User Deﬁned commands — The User Defined sub-tab lets you enter commands

in ASCII or hexadecimal, including SIS commands, to assign display functions that are not pre-deﬁned in your device driver. (Refer to the user manual for the display device or switcher to ﬁnd out what commands are supported.)

 Actions — A Button Selection action emulates a button press on the MLC 62 front

panel, causing all functions programmed to the button to be performed. The Actions sub-tab lets you add all the commands assigned to another front panel button to the button you are conﬁguring, emulating a press of the other button. Actions are available for each of the MLC buttons. When you add an action to a button and press it, all the functions programmed to that button are performed, followed by all the functions on the button whose action you added.

Extron MLC 62 MediaLink Controllers • Software-based Conﬁguration 49

 Button ﬂashing — The Flash sub-tab lets you add a ﬂash period with a duration

of 1 to 120 seconds to the button. You can also specify whether the button ﬂashes rapidly or slowly during this delay period. During the ﬂashing period, all front panel buttons are disabled and do not respond to pressing.

NOTE: You cannot add ﬂash commands to a power button on this tab. To adjust

the length of time the power buttons ﬂash during power-up and powerdown, see “Selecting display power settings,” later in this section.

Assigning driver commands to buttons

After you have selected a driver for your display device or switcher that will be controlled by the MLC 62, you are ready to assign the commands that are available with that driver to the buttons on the MLC 62 front panel. The Driver sub-tab on the Front Panel tab contains a list of the commands available with the driver. From this ﬁeld, you select commands to assign to the buttons.

Figure 52. Adding Commands to a Button

Extron MLC 62 MediaLink Controllers • Software-based Conﬁguration 50

If you selected the Display (RS-232) port and want to keep the auto-ﬁlled commands, you need to add commands only to the last four buttons (by default conﬁgured as input selection buttons and labeled PC, Video, Laptop, and Mute). If you have selected the IR or Serial port, or if no power or volume commands are available with your driver, you need to conﬁgure all of the buttons.

NOTE: Relay 1 Pulse (1 second) and Relay 2 Pulse (1 second) commands are

automatically added to the power On and Off buttons, respectively, on the RS models. This is a common conﬁguration that can be used to raise and lower a motorized screen that is connected to the Relay port.

To add driver commands to each button, follow these steps and refer to the illustration on the previous page:

1. Click the Front Panel tab to display the diagram of the front panel buttons.

2. Click on the button to be conﬁgured. The following occurs on the screen:

 A yellow box surrounds the selected button. (In the example on the previous

page, the display power On button was selected.)

 The ﬁelds in the Button Settings section change to reﬂect the current settings for

the selected button.

3. On the Driver tab in the Button Operations section, click the + sign in front of the

driver name to expand the menu and view the commands available with that driver.

4. On the Driver sub-tab, click on the name of the command to be programmed onto

the selected button. In the example above, the Power On command was selected for the On button.

5. Click the green right arrow between the two Button Operations ﬁelds. The selected

driver command is displayed in the current commands ﬁeld, to the right of the Driver sub-tab.

When a command is added to a button, a red triangle covers the upper-left corner of the button on the screen.

In the example on the previous page, the Mute button is set up as a toggle (indicated by its division into two different colored sections). When you click on it, two ﬁelds, labeled Toggle On and Toggle Off, appear in the current commands ﬁeld.

Figure 53. Driver Sub-tab and Current Commands Fields for a Toggle Button

To add commands to a toggle button, repeat steps 3 and 4 for each of these ﬁelds to add different commands to them. (See “Setting the button modes,” later in this section, for instructions on creating a toggle button.)

6. If desired, repeat steps 3 through 5 to assign more commands to the button. You can

add multiple commands to any button, including each portion of a toggle button. After the conﬁguration has been uploaded to the MLC, when you press the button the commands are performed in the order they appear in the Button Operations ﬁeld.

Extron MLC 62 MediaLink Controllers • Software-based Conﬁguration 51

Removing Commands

To remove a command from a button:

1. In the current command display ﬁeld, click to highlight the command that you want to

remove.

2. Click the Remove button above the current command ﬁeld.

Reordering Commands

When a button has multiple commands assigned to it, you can specify the order in which the commands are performed, as follows:

1. In the current command display ﬁeld, select the command that you want to move.

2. Click the green Move Up or Move Down arrow button above the current

command ﬁeld to move the selected command higher or lower on the list. The commands are performed in the order they are listed in this ﬁeld.

Automatic button settings for the Display port (RS models only)

If you select the Display port to conﬁgure, the software automatically adds the following commands (if available with the selected driver) to the power On, power Off, and Volume buttons.

 Power and volume commands are added to the MLC front panel Power and Volume

buttons. The diagram on the Front Panel tab reﬂects these changes.

 Warm-up and cool-down periods are speciﬁed for projectors and displays. (See

“Selecting display power settings,” later in this section.)

 The Serial Port settings are selected from the Baud Rate, Data Bits, and Parity menus

(serial conﬁgurations only).

This sets up a commonly-used conﬁguration. If desired, however, you can remove any of these commands and replace them with others, as described below.

Setting the button modes

Button modes determine how the buttons respond when pressed or how they are grouped to function together. The button color on the Front Panel tab indicates the current mode of the button. The following button modes are available:

 Power On and Power Off — Gold

Groups two buttons to be mutually exclusive. If you press a button in Power On or Power Off mode on the physical front panel, it lights brightly while the other button dims and becomes inactive.

 Volume — Green

Repeatedly pressing or pressing and holding a physical button in Volume mode increases or decreases the audio volume on the display device in increments speciﬁed in the device driver. Only the Volume buttons can be in Volume mode, and they cannot be changed from this mode.

 Input — Cyan

All buttons in this mode form a mutually exclusive group. When you press a button in Input mode, it activates and lights brightly while all other buttons in input mode become inactive and dim.

 Toggle — Gold and pink

In this mode, two commands (or command sets) are programmed to the button. Repeated presses of the button on the front panel switch back and forth between the two commands.

Extron MLC 62 MediaLink Controllers • Software-based Conﬁguration 52

 Single switch — Silver

The button functions independently of all other buttons. A single press issues a single command.

 Single power — Gold and orange

In Single Power mode, the button toggles between issuing a power on and a power off command. This mode is similar to Toggle mode, except for warm-up and cooldown periods, during which the button blinks. Only one button at a time can be set to Single Power mode, and only if no other power buttons have been deﬁned.

 Group1 — Blue; Group2 — Pink

Buttons in either of these modes function the same as in Input mode. Use these modes if you want to form groups of buttons in addition to your Input mode group.

For more detailed information on button modes and their uses, refer to the MLC 62 conﬁguration software help ﬁle.

Default button mode settings

For the default conﬁguration, the button modes are set as described below. To save time when getting started, it is recommended that you assign commands that are appropriate for the current mode of each button. For example, if you assign an Input Video command to the blue Video button (which is in input mode), you ensure that only the video input is selected when you press that button, and you do not have to change the button mode or label.

 On and Off buttons (buttons 1 and 2): Set to Power On and Power Off modes

(gold).

 Vol- and Vol+ buttons (buttons 3 and 4): Set to Volume mode (green).  PC, Video, and Laptop buttons (buttons 5, 6, and 7): Set to Input mode (cyan).  Mute button (button 8): Set to Toggle Switch mode (gold and pink)

Selecting the button mode

If you want to change the mode of a button in order to assign the desired commands to it, follow these steps:

1. Select the Front Panel tab.

2. On the front panel diagram, click on the desired button.

3. From the Button Mode drop-down menu in the Button Settings ﬁeld, choose the

mode for the selected button. The button changes to the color of the mode you selected. (See the illustration on the next page.)

Extron MLC 62 MediaLink Controllers • Software-based Conﬁguration 53

Figure 54. Button Mode Menu on the Front Panel Tab

Other button settings

The Front Panel tab also provides the following settings for the buttons. Refer to the MLC 62 conﬁguration software help ﬁle for detailed procedures for changing these settings.

 Button Text — Enter a label name for the selected button.  Repeat Rate menu — If you press a button and hold it, the MLC continually repeats

the command(s) programmed to that button in sequence, for as long as you hold the button. From this menu you can select the number of seconds that the MLC waits before repeating the command(s).

 Button Layout — Click Combine to create a single long button from the selected

button and the one next to it. Click Separate to create two buttons from a combined one. (Only buttons 5 through 8 can be combined.)

 Reset — Click Reset to return all settings you have entered on the Front Panel tab to

the default conﬁguration.

Adding relays to buttons

In addition to driver commands, you can add relay commands to the front panel buttons to control devices (such as room lights or a motorized screen) that are connected to one or both of the MLC relay ports. When a button containing relay commands is pressed, the relay state is changed, causing the device connected to the relay port to perform its function (turning on or off, raising or lowering, and so on). (If a button containing relay commands also contains driver commands, those commands are performed as well when the button is pressed.)

The following modes are available for the relay ports:

 On — Acts as normally closed.  Off — Acts as normally open (default).  Toggle — Changes the relay back and forth between closed and open states with

each button press.

 Pulse — Closes the relay for a speciﬁed number of seconds with each button press.

For convenience, the default button conﬁguration includes relay commands added to the display power On and Off buttons (a common motorized screen relay setup). These relays could be used, for example, to lower or raise a motorized screen whenever the projector power is turned on or off.

Conﬁguring the Digital Input Port

The Digital Input port on the MLC 62 rear panel lets you connect a switch or sensor to control other devices that are connected to the MLC serial, IR, and relay ports. On the Digital Input tab, you can assign commands to the high and low states of the Digital Input port. When the switch or sensor connected to the port is activated (for example, motion or temperature change is detected, a switch button is pressed, or a key is turned), the port crosses the threshold into its other state. This triggers the MLC Relay, Display, or Serial port to issue speciﬁed commands to the devices connected to them. The connected devices then perform actions in response to these commands. (Conﬁguring the Digital Input port is optional.)

Example: You could conﬁgure the Digital Input port so that when a button is pressed or a key is turned on a connected switch, the projector (connected to the Display or Serial port) powers on, the room lights (connected to one of the Relay ports) turn off, and the motorized projector screen (connected to the other Relay port) lowers.

Switches and Sensors

Most types of switches and sensors can be connected to the Digital Input port. Switches can be any type; for example, a key that turns, one or two buttons, or a rocker. Switch operation can be momentary (the action is performed only while the switch is held) or latching (the switch remains in the position to which it was set and the action continues until the switch is put in its other position). Sensors can include motion sensors, temperature sensors, current sensors, and so forth.

Port states

The Digital Input port has two pins, between which a circuit is either formed (closed) or broken when the switch or sensor connected to the port is activated. When a circuit is formed between the two pins of the Digital Input, the port is in a low state. The changing of the port from a high state to a low state triggers the MLC to issue all commands that have been speciﬁed for the Digital Input port low state to the devices connected to those ports.

 In Input with Pullup mode: When you press, turn, or ﬂip the switch again so that

the circuit between the two pins of the Digital Input port is broken (becomes open), the port changes to its high state. The change from the low state to the high state triggers the other MLC commands speciﬁed for the port high state on connected devices.

 In Input mode: To change back from a low to a high port state, a voltage of 1.5 V to

24 V must be applied to the two pins.

Command types for the Digital Input port

The following types of commands can be added to the Digital Input port via the sub-tabs on the Digital Input screen. Refer to the MLC 62 conﬁguration software help ﬁle for details on each type of command.

 Driver commands — The Driver sub-tab lets you specify commands that will be

issued from the IR, IR/S, or RS-232 ports to the connected display device or switcher when the Digital Input port detects a change in its state. (The MLC issues commands in response to the change of port state in the same way it does when a front panel button is pressed.)

 Relays — The Relay sub-tab lets you specify relay commands that will be issued

from the Relay ports when a change in state is detected. Devices connected to the Relay port could include a projector screen that is to be raised and lowered, room lights that are turned on and off, or a low-voltage controller (LVC) to which a device is connected.

Extron MLC 62 MediaLink Controllers • Software-based Conﬁguration 56

 Time delays — The Time Delay sub-tab lets you insert a delay of a speciﬁed number

of seconds between functions when multiple commands have been assigned to the port. You can set the amount of seconds that the MLC waits after issuing a command before it issues the next one. The delay period can be from 0.5 to 90 seconds in 0.5 second increments.

 User Deﬁned commands — The User Defined sub-tab lets you enter commands in

ASCII or hexadecimal, including SIS commands, to assign display functions that are not pre-deﬁned in your device driver. These commands can be entered in either or both Trigger ﬁelds to apply them to the high or low state of the Digital Input port. (Refer to the user manual for the display device or switcher to ﬁnd out what commands are supported.)

 Actions — The Actions sub-tab lets you add all the commands assigned to a front

panel button to either of the Trigger states of the Digital Input port, emulating the press of another button. When the Digital Input port detects a change to its high or low state, all functions programmed to the speciﬁed button are performed the same as they would be if the actual button on the front panel were pressed.

NOTE: Placing the MLC in executive mode (front panel lockout) is an

action available via this sub-tab. See “Locking the front panel

from the Digital Input port,” later in this section, or refer to the

MLC 62 conﬁguration software help ﬁle for procedures.

Assigning commands to the Digital Input port

On the Digital Input tab, you can select commands or actions that will be triggered when the port detects a change from the high to low state, and other commands that will be triggered when a change from the low to high state is detected.

Figure 56. Adding Commands to the Digital Input Port

Extron MLC 62 MediaLink Controllers • Software-based Conﬁguration 57

To add commands to the Digital Input port:

1. Connect a switch or sensor to the Digital Input port. See “Wiring the Digital Input

Port” in the “Features, Installation, and Operation” section for more information

about connecting to this port.

2. On the MLC 62 window, select the Digital Input tab.

3. Select the digital input mode from the drop-down menu at the top of the Digital

Input tab. Options include:

 Input with Pullup — If the switch, sensor, or other device connected to the

Digital Input port does not provide its own power or is a completely mechanical device, placing the port in Input with Pullup mode enables the MLC Digital Input port to pull up to TTL (approximately 5 V) when the contacts are open. The MLC provides approximately 4.5 V of power.

 Input — If the connected device provides power in the range of 0 V to 24 V, the

port can be placed in input mode.

4. In the Input Operations ﬁeld, select the sub-tab (Driver, Relay, Time Delay, User

Defined, or Actions) containing the commands that you want to assign to the two

states of the Digital Input port, to be initiated by the connected switch or sensor.

5. If the display device is connected to the IR/S port and the port is conﬁgured for IR, it

can have multiple drivers. All added drivers are listed on the Driver sub-tab. Select the driver for your connected device, then either click the + sign in front of its name to view its commands or proceed to step 6.

6. On the selected sub-tab, click on a command or action that you want to assign to one

of the port states.

7. Click one of the green right arrow buttons located to the right of the sub-tab to place

the command in one of the Trigger ﬁelds:

 Click the arrow button beside the Trigger: High to Low ﬁeld (bottom) if you want

the selected command to be issued when the port state changes from high to low.

 Click the arrow button beside the Trigger: Low to High ﬁeld (top) if you want the

selected command to be issued when the port state changes from low to high.

The command appears in the Trigger ﬁeld for which the arrow button was clicked.

8. Repeat steps 4 through 7 as desired to add more commands to the Trigger ﬁelds.

NOTE: The Trigger ﬁelds list all commands that have been assigned to the high

and low states of the port. When the switch or sensor triggers a change to the state of the Digital Input port, the functions assigned to one of the states are performed in the order that the commands are listed in the Trigger ﬁeld.

Example: If the room lights are currently on and you want them to be off when the projector is being used, you could assign the following commands to the Trigger: High to Low ﬁeld (shown in the illustration on the previous page):

 A Power On driver command to turn on the projector, and  A Relay 1 Off command to turn off the room lights (which are connected to the

Relay 1 port via a low-voltage controller).

When the switch or sensor is triggered to change the Digital Input port state to low, this state change causes the switch to turn the lights off and the projector on.

Locking the front panel from the Digital Input port

To lock and unlock the MLC front panel using the MLC 62 conﬁguration software, modify the current conﬁguration by adding Enable Front Panel and Disable Front Panel actions to the Digital Input port. For this method, a switch or sensor must be connected to the Digital Input port. When the switch is activated or the sensor detects the condition that causes it to trigger a front panel lockout, the MLC goes into executive mode. When the triggering condition changes or the switch is activated again, the front panel is unlocked.

To conﬁgure the Digital Input port to lock and unlock the front panel when triggered:

1. Connect a switch or sensor to the Digital Input port. See “Wiring the Digital Input

Port (RS Models Only)” in the “Features, Installation, and Operation” section, for

information about connecting to this port.

2. Open the MLC 62 conﬁguration program and select either the current conﬁguration

or one that you plan to upload to the MLC.

3. On the MLC 62 window, select the Digital Input tab.

Figure 57. Adding Executive Mode Actions to the Digital Input Port

4. In the Input Operations ﬁeld, select the Actions sub-tab.

5. On the list of actions on the Actions sub-tab, click Disable Front Panel.

6. Click the green right arrow button between the Input Operations ﬁeld and the

Trigger Low to High ﬁeld. “Disable Front Panel” is displayed in the top Trigger ﬁeld, preceded by “Action:”. (Alternatively, you can drag the Disable Front Panel action from the Actions sub-tab to the Trigger: Low to High ﬁeld.

7. Select Enable Front Panel from the Actions sub-tab.

8. Click the green right arrow button beside the Trigger: High to Low ﬁeld (bottom), or

drag the Enable Front Panel action to the Trigger: High to Low ﬁeld.

9. Save the conﬁguration and upload it to the MLC. (See “Conﬁguration File

Management Procedures” and “Uploading a Conﬁguration to the MLC,” later

in this section.)

Specifying Advanced Conﬁguration Settings

The Advanced Configuration tab provides some additional settings for the display device and the MLC. Make changes to these settings as desired.

Figure 58. Advanced Configuration Tab

Selecting display power settings

In the Display Power Settings section of the Advanced Conﬁguration tab, you can specify certain parameters for powering your display device on and off. These settings are normally speciﬁed within the driver; however, you can make changes to the following settings.

 Auto shut-off display power after being inactive for: — From this menu, select

the number of minutes the MLC will remain idle (with no front panel buttons pressed) before it sends a power off command to shut down the display. The range is none (—) to 480 minutes.

 When powering up, delay for: — From this menu, select the number of seconds

the display device takes to warm up after the MLC Power On button is pressed. The range is none (—) to 300 seconds. The MLC Power On button blinks rapidly during this warm-up period.

NOTE: If the display device is connected to the Display port, the warm-up and

cool-down delays are automatically ﬁlled in when the device driver is added during port conﬁguration (if these functions are available with the driver).

 When powering down, delay for: — From this menu, select the number of seconds

the display device takes to cool down after the MLC Power Off button is pressed. The range is none (—) to 300 seconds. The MLC Power Off button blinks slowly during this cool-down period.

 Disable buttons when Display Power is Off — Select this check box to disable

all the MLC front panel buttons except the Power buttons when the display device is powered off.

 Enable 2 second hold on Power Off — Select this check box to require that the

MLC Power Off button be held for 2 seconds in order to power off the display device. After 2 seconds, the Power Off command is sent, the button begins to blink slowly, and the device starts to power down.

Extron MLC 62 MediaLink Controllers • Software-based Conﬁguration 60

Specifying the volume table resolution

If the display device connected to your MLC 62 has a volume table in its driver, the display volume is increased or decreased by increments speciﬁed in the volume table each time a Volume button is pressed or pressed and held. You can conﬁgure the MLC to skip speciﬁed volume increments, essentially reducing the number of steps in the volume table, when the MLC buttons are pressed or held. This enables you to raise and lower the volume at a faster rate.

To select volume table increments to skip:

 From the Volume Table Resolution menu, select which volume increment

commands you would like the MLC to skip when raising or lowering the volume. For example, if you select skip 1 command play next, the MLC would increase the

volume by every other increment in the volume table.

Enabling and disabling the button press beep

The MLC 62 can be conﬁgured to emit an audible beep whenever a front panel button is pressed or otherwise activated. To enable the button beep:

 Select the Beep when button is pressed check box at the bottom of the

Advanced Configuration tab.

 To disable the beep, deselect the check box.

Conﬁguring Using IR Learning

If no Extron driver is available for your display device or you would like to add some functions to the device driver you have, you can use IR Learning to create a new driver or to edit an existing one, using the remote control of the device.

SIS Control

The MLC 62 can be remotely controlled via a host computer or other control device that is attached to the MLC rear panel Host/Conﬁg port. You can issue Simple Instruction Set (SIS) commands to the MLC via the RS-232 or USB interface of your computer or control device with a communication software program such as HyperTerminal or DataViewer. This section contains a list of the SIS commands available for the MLC 62 and describes procedures for issuing them. The following topics are covered:

 Host-to-Controller Communications

 Using the Command/Response Table

 Command/response Table for SIS Commands

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 62 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 62 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 2010, Extron Electronics, MLC 62, Vx.xx, 60-100n-nn where Vx.xx is the ﬁrmware version number and n is the MLC 62 model number. This message does not appear with a USB connection.

Error Responses

If the MLC 62 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 E13 – Invalid value (out of range) E14 – Not valid for this conﬁguration E22 – Busy

Extron MLC 62 Series MediaLink Controllers • SIS Control 83

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.
