Introduction

About This Manual

This manual provides detailed information and best practices recommendations about cabling and configuring the Extron MLC 104 Plus Series MediaLink® Controllers, and reference information about the controllers’ specifications, dimensions, programming, and special applications.

It does not contain instructions on the most basic setup steps: those are covered in the MLC 104 Plus Series Setup Guide, which describes how to set up the hardware, how to use the Global Configurator (GC) program to download drivers, add A/V devices to a GC configuration, configure the front panel buttons, set a shutdown schedule, and set up e-mail alerts to flag a projector disconnection or warn that lamp hours are exceeded.

NMLC 104 Plus requires GC version 2.50 or higher. The IP models work with GC version 2.2 or higher

About the MLC 104 Plus Series MediaLink® Controllers

The MLC 104 Plus Series MediaLink Controllers are capable of controlling a projector and various other items such as lights, a projector lift, or a screen motor. Throughout this manual they are also referred to as the MLC 104, MLC, or “controller.” All models offer RS-232 and IR-based projector (display) control; digital inputs and outputs for controlling items such as a projector lift, motorized projection screen, and lights; and RS-232 remote control of an Extron switcher.

MLC 104 Plus Series features

All models can be configured and controlled via a host computer using RS 232 communication, and the MLC 104 IP Plus models can also be configured and controlled via IP Link™ Ethernet control. Setup and control can be accomplished by simple ASCII commands (Simple Instruction Set, SIS™) or via the included Global Configurator program. The software offers many more setup options than does SIS programming.

All models offer front panel controls. The optional IR 402 remote control (which requires an optional IR signal repeater) and optional SCP 104 Series hardwired control pads can be used with the MLC, and they mirror the MLC’s front panel controls. Additionally, the MLC 104 IP Plus DV+ includes an IRCM-DV+ control module (for DVD and VCR control) installed in the faceplate.

Additional features for IP models

Via Ethernet/IP communication the MLC 104 IP Plus models can make use of the controller’s embedded Web pages, which include online diagnostics and

monitoring of basic control features. As an integrated part of the MLC 104 IP Plus, IP Link provides the following advantages:

Global compatibility — The MLC uses standard Ethernet communication protocols, including ARP, DHCP, ICMP (ping), TCP/IP, Telnet, HTTP, and SMTP.

Embedded Web page serving — The MLC 104 IP Plus offers up to 7.25 MB of flash memory for storing Extron and user-supplied Web pages, configuration settings, and device drivers. Data in flash memory is served at a transfer rate of 6 Mbits per second.

Multi-user support — Up to two hundred (200) simultaneous connections enable each IP Link device to support many concurrent users and improve system throughput by sending information in parallel.

Management ability via Global Configurator 2.2 and higher — The included software and the GlobalViewer Web pages associated with it allow you to control, monitor, and schedule various functions of products connected to IP Link products such as the MLC.

1-2 MLC 104 Plus Series • Introduction

E-mail notification — The MLC 104 IP Plus can be set up to send an e-mail when the projector has been disconnected or the projector’s lamp has been used for a designated number of hours.

Controlling other devices

The MLC 104 Plus Series offers two methods of projector or display control: RS-232 or infrared (IR). The MLC can learn IR signals from remote controls to communicate with sources such as VCRs and DVD players. Users can create their

own device drivers (IR or RS-232) or go to the Extron Web site (www.extron.com) to obtain device drivers.

A typical application for an MLC 104 IP Plus MediaLink Controller

Projector Control

The MLC can control a projector or other display device by using IR or RS-232 control. The MLC must be configured for projector control in one of the following ways before it will send commands to the projector:

•An IR or an RS-232 driver file can be installed from a disk, downloaded from the

Extron Web site (www.extron.com), or downloaded from Extron using the driver subscription feature within Global Configurator. The driver is saved to a folder within C:\Program Files\Extron\Driver2, and it is uploaded to the MLC via Global Configurator.

•RS-232 command strings can be entered directly from a host computer using

Extron Global Configurator software.

•IR commands can be entered directly from an IR remote control through IR learning and the Extron IR Learner software to create a driver that the MLC can use. IR learning is convenient for installing new or updated commands into the MLC in the field.

How the MLC 104 Plus Series Controllers Work: MLC Components and Interactions

Unlike the Extron MLC 206 Series MediaLink Controllers, the MLC 104 Plus Series requires and uses event files to perform all functions except basic input switching and volume control. The event files define, monitor, and govern how an MLC 104 Plus Series controller works. Below are example diagrams of how the MLCs interact with accessories, event scripts, drivers, ports, and input and output devices.

ports, configured buttons and digital inputs or outputs, and set up IP addresses and functions), that information is saved to a project file that is uploaded into the MLC.

The configuration information is used to create the “main event” (0.evt) script file that defines the MLC’s operation. The main event file also controls and monitors ports, optional SCP control panel(s), and changes made at the MLC’s front panel (FPC, front panel control).

Each button on the MLC and on any connected SCPs has two switch numbers assigned to it: one for the button press, one for release. Scripts are compiled to generate the main event file to monitor any button press or release and to generate the actions (issuing commands, triggering relays, switching inputs) associated with the buttons.

Optional Control Modules and IR 402 Remote Control

The MLC can “learn” IR commands from a VCR’s, DVD’s, tape deck’s or other device’s remote control, allowing you to create an IR driver file that can be incorporated into the MLC’s event scripts. A command can be associated with each of the buttons on an optional infrared control module (such as the Extron IRCM VCR, CM-5BB, CM-9BLB, or IRCM DV+) in order to allow limited control of source devices.

A total of four control modules (a maximum of four control module addresses) can be installed with this MLC. Refer to the Control Modules User’s Manual and the

IRCM DV+ Control Module User’s Manual for installation details and read the Global Configurator Help file to learn about configuration. See chapter 4 of this manual for special SIS commands for the IRCM-DV+.

Buttons

The MLC 104 Plus Series controllers have backlit buttons. The functions, events, and scripts associated with these buttons are available with all models. Pressing the corresponding button on the Extron IR 402 remote control or an Extron SCP 104 keypad will cause that button’s functions to be executed exactly as if you had pressed a front panel button.

By default all buttons illuminate brightly when selected (active), and light dimly when deselected. The button caps are removable so the button labels can be changed.

Each Display On/Off, Function/Room, and Input 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, audio source, etc.)

•a time delay operation—insert delays between executed commands

•a button light operation—change a front panel button’s brightness, color, or flashing

•a digital input/output operation—turn the digital output on or off, toggle it, or pulse it

•a user-defined RS-232 operation—issue a non-driver-associated RS-232 command (one that you programmed separately) via a specific port (IR/Serial Out A, B, C; or the projector control port) or an internal command for the MLC, itself

power it off. By default, only one of these two buttons can be selected (active) at once. Via Global Configurator (GC) software, other functions and relays can be associated with each of these buttons.

NTo avoid conflicts with the front panel lockout PIN feature, Extron recommends configuring the Display Power buttons so that the MLC sends projector/display commands upon the button release instead of on the button press.

	the picture at right.

Alternatively, the buttons can be reconfigured (via software) to

select different inputs and to trigger different commands. See chapters 3 and 4 for details.

Press an input selection button to select the desired audio and video input on the projector or an optional Extron switcher. The button for that selection lights brighter and remains lit brighter until a different input is selected.

NWhen these input selection buttons are configured for input switching, there is a default 0.5 second delay between when one input is selected and when a different input can be selected. This allows time for the projector to adjust to the change of sync signals. The delay period is adjustable.

If the MLC is used without an optional switcher and the MLC has been set up for use with a projector, the selectable inputs on the MLC correspond to the number of inputs available on the projector. If an optional Extron switcher is connected to the MLC, all four input buttons are selectable. Which buttons are or aren’t configured for input switching can be set via Global Configurator.

N When an input selection button is designated for input switching, pushing that button causes the MLC to send out an SIS input change command via the MLS RS-232 connector. In addition it can make the MLC send projector control commands through the Display RS-232/IR port, send a digital output signal, or send a serial command via the MLS RS 232 port.

	Web browser control.
	The Global Configurator software lets you select whether this knob controls
	the projector’s audio levels or the optional switcher’s audio levels. If the knob
	controls the projector’s audio levels, you can specify incremental adjustments
	or range-based adjustments (via device driver only). See chapter 3 and the
	software’s help file for details.

2-4 MLC 104 Plus Series • Operation, Features, and Cabling

NNot all devices that use RS-232 for audio level control can be properly controlled using the MLC’s Volume knob. Some devices cannot respond quickly enough to the commands issued to them by the MLC.

•If the projector uses range adjustments, that can result in choppy audio level ramping (volume changing in jumps).

•If the projector uses incremental adjustments (volume up/down commands), that can result in slow audio ramping (requiring many turns of the knob to change the volume).

If you experience problems using range-based audio control with a projector or other device, try slowing down the MLC’s volume knob command rate by using the 49# SIS command (see chapter 4 on SIS programming for details) or encoder scaling in Global Configurator (see the Global Configurator Help file). If you need further assistance, contact Extron and ask to speak with an applications engineer.

If the MLC is configured for use with a MediaLink Switcher or for some projectors, the MLC’s LEDs indicate volume ranges (with steadily lit LEDs) and minimum/maximum volume limits (with flashing LEDs), as shown in the following diagram.

Front Panel Security Lockout (Executive Mode\

To prevent accidental changes to settings, the MLC features front panel security lockout (executive) modes for disabling access to controls. When front panel lockout is enabled, if a button is pressed, the button flashes red, but no change occurs. Nothing—not input switching, projector control, room control, volume adjustment, or any other knobor button-executable function—results from front panel actions when lockout is active. Button and knob functions on the IR 402 remote control, SCPs, or control modules are also locked. Changes can still be made via RS-232 or, for IP models, via Ethernet (Telnet or Web browser) control.

The SIS command 3X corresponds to and also enables this mode (see page 4­-10). For details, see chapters 3 and 4. The only way to override a front panel lockout via the front panel is to enter a personal identification number (PIN) to unlock the panel, using the MLC’s input buttons as a numeric keypad for PIN entry, as shown on page 2 7.

Enabling and disabling front panel lockout via the embedded Web pages and the front panel

Front panel lockout can be enabled/disabled using the embedded Web pages whether or not a PIN has been set. However, a PIN must be set up before you can enable or disable lockout using the front panel buttons.

Using the Web pages (IP models)

1.Using a Web browser, enter the MLC’s IP address to open the MLC’s embedded Web page. If an administrator password has been set and if you are prompted to do so, type in the administrator password.

2.Click on the Configuration tab, which opens to the System Settings page.

3.Select either Off or Disable Front Panel, SCP, Control Modules and IR in the Executive Mode settings area. See the following picture.

NIf Disable Front Panel, SCP, Control Modules and IR is selected via the System Settings factory default Web page, front panel lockout can’t be enabled/ disabled via the front panel unless PIN Mode is enabled. See page 4-40 to find the SIS commands for PIN enabling/disabling.

2-6 MLC 104 Plus Series • Operation, Features, and Cabling

Using the front panel (all models)

One or more PINs must be configured before this procedure can be used. See “Preparing the MLC for front panel lockout” on page 2-8. To lock/unlock the front panel, you use the Display On/Off buttons to change modes and use the input buttons as a numeric keypad.

N Make sure the projector or display is off before using a PIN to lock the front panel.

NFailure to configure the On or Off buttons to send display/projector commands upon button release (instead of button press) may cause problems with the PIN Mode feature. (If one On/Off button is pressed before the other, and the buttons are configured to send commands at the button press, the first button’s actions can be executed, preventing you from locking the front panel until the display’s warm-up or cooldown period finishes.)

Preparing the MLC for front panel lockout

To allow access to front panel changes to specific personnel while the front panel is locked, you can set a user and/or administrator PIN and set which type of PIN, if any, is allowed to unlock the panel.

Setting up and enabling or disabling PINs

Using the Advanced Configuration tab within Extron Global Configurator (GC) software, you can configure which PIN to enable (which PIN will be allowed to unlock the front panel), or disable both PINs so that no one can access the front panel during front panel lockout. And you can set the four-

digit PINs for the administrator and for users.

NEach digit of the PIN must be a number from 1 to 4 because they represent the MLC’s four input buttons, which will be used as a

numeric keypad. By default, both PINs are set to 1423. Refer to the Global Configurator Help file for the PIN setup procedure.

Scheduling front panel lockouts

You can set the MLC’s front panel to be automatical-

ly locked at certain times and days by setting up a schedule using the Schedule tab within the Global Configurator software and uploading it to the MLC. The Global Configurator Help file includes instructions on how to set up a scheduled action.

IR remote control

The MLC 104 Plus Series controllers do not have a built-in IR receiver that accepts signals for controlling the MLC, itself. However, you can connect an Extron IR Link or an IR Sensor remote IR receiver to the MLC’s CommLink port as shown in “Additional control connections,” starting on page 2-12. Those devices can receive signals from an Extron IR 402 infrared remote control, which mirrors the MLC’s front panel controls, and sends them to the MLC.

Wiring for IR display control

Wiring varies depending on the projector/display model. In most cases the drivers are bidirectional, but sometimes only the transmit (Tx) and ground connections will be needed for projector/display control. For bidirectional RS-232 communication, the transmit, ground, and receive pins must be wired at both the MLC and the projector or display.

NEach projector or display may require different wiring. For details, refer to the manual that came with the projector/display or the Extron device driver communication sheet.

NMaximum distances between the MLC and the device being controlled may vary up to 200 feet (61 m). Factors such as cable gauge, baud rates, environment, and output levels (from the MLC and the device being controlled) all affect transmission distance. Distances of about 50 feet (15 m) are typically not a problem. In some cases the MLC may be capable of transmitting and controlling a given device via RS-232 up to 250 feet (76 m) away, but the RS-232 response levels of that device may be too low for the MLC to detect.

Alternatively, an MLC can use infrared signals and IR Emitters to control several source devices. However, the MLC’s direct insertion captive screw connectors have small openings that accept just one wire per pole. To connect up to two IR Emitters to the MLC, insert one ground and one signal wire

in the MLC’s Display RS 232/IR port, then connect the IR Emitters to those wires. If using all single emitters or all double emitters, wire the emitters in parallel. If using a mix of both single and dual emitters, see the IR Emitter Installation Guide, part number 68-808-01.

Additional control connections

B	CM/IR/SCP (CommLink) port — For remote control of the MLC 104 Plus
	Series controller or other items, you can connect up to four Extron control
	modules (IRCMs, ACMs, RCMs, CMs), one Extron infrared signal repeater
	(IRL 20 or IR Link), and/or up to two Extron SCP 104 control panels to this
	port. A maximum of seven devices can be connected to this port. See the
	figures on pages 2 13 and 2 14.

NThe SCP 104 must have firmware 1.01 or greater and DIP switch 4 in the On (up) position to operate with an MLC 104 Plus Series controller. Refer to the SCP 104 User’s Manual for more details.

The SCP 104 replicates the MLC’s front panel controls. The SCP 104 and the IR signal repeater can receive IR signals from an optional IR 402 remote control and send them to the controller. Control modules can be used (once the MLC is set up) to control VCRs, DVD players, tape decks, a projector lift, or screen control. Refer to the appropriate device’s user’s manual.

NIf outside factors such as fluorescent light interfere with and affect the function of the MLC, you can disable IR control of the MLC. Using a special function SIS command (65#), you can turn off the MLC’s ability to receive IR signals from IR signal repeaters and SCPs.

The control modules, IR signal repeater, and SCPs can be daisy chained. Wire the connections as shown in the diagrams on the following pages.

Extron Comm-Link (CTL and CTLP) cable is recommended for these connections. Before inserting wires in the connectors, strip the cable and apply heat shrink as shown at right.

TFor best results and to avoid short circuits, Extron recommends using shielded wires or wires insulated using heat shrink (instead of bare wires) for the common/drain wires.

NThe maximum distance between the MLC and a connected device is 200’ (61 m).

C	Digital I/O ports — The Digital I/O area (shown at right) provides
	three ports that can be configured as digital inputs or outputs,
	with or without +5 VDC pull-up. Connecting these ports to
	sensors, switches, LEDs, or relays allows for a way to trigger
	events or functions (such as triggering relays, issuing commands,
	or sending an e-mail) that have been configured using Global
	Configurator (GC) software.

CConfigure these ports using Global Configurator software or SIS commands first, and then connect wires the MLC’s ports. A mismatch between port configuration and wiring can cause malfunctions or unit failure.

Digital input — To allow the MLC to monitor devices such as push buttons, connect a switch, motion sensor, moisture sensor, tally feedback output, or a similar item to a digital input port. When one of these ports is configured as a digital input, it is set to measure two states: high and low. The port accepts 0 to 12 VDC input. The threshold voltages are as follows: a voltage below 2.0 VDC is measured as logic low, and a voltage above 2.8 VDC is measured as logic high. There is also an internal, +5 VDC, selectable, pull-up resistor for this circuit.
