MLC 206 Setup Guide, cont’d

Step 1 — Computer Connection

The MLC 206 must be connected to a PC in order to conﬁgure the controller. The

conﬁguration port, shown in the rear panel view below, is used for system control

and for loading conﬁguration and driver ﬁles into the MLC.

1. Connect a host computer to the MLC 206 Conﬁg port via the rear

panel 9‑pin HD female RS‑232 connector. Use a serial cable with

9‑pin D connectors.

with the software. Connections for IR and serial control can be installed

after conﬁguration.

MediaLink Switcher (MLS) to the MLS/Power port, and connect the power

supply or the switcher to a power source.

Step 2 — Software Installation

The MLC must be conﬁgured before it can send commands to the projector or other

devices. Install the MediaLink Control Program software on the host PC. To install

the software, run SETUP.EXE from the Extron‑provided disk. Follow the instructions

that appear on the screen.

N The software is also available at www.extron.com.

MLC 206 Setup Guide, cont’d

Step 3 — Setting up projector control

Device drivers allow the MLC 206 to control projectors and other source devices via

RS‑232 or IR.

N It is strongly recommended that an RS-232 control (ﬁlenameRS1.mll) ﬁle for

controlling a projector be used whenever possible.

To load a driver and conﬁgure the MLC 206:

1. Start the MediaLink Control Program.

The appearance of the screens varies depending on which

accessories (control modules and/or MediaLink Switcher)

are connected to the MLC, as shown in the following

pictures.

MLC 206 without accessories MLC 206 with an MLS switcher,

IRCM-DV+, and RCM-SC connected

2. Load a projector driver: select the third tab, Controller (MLC) Config, and

select the Load Extron Driver button, as shown in the following illustration.

Choose the appropriate projector driver (ﬁlename.mll) from the on‑screen

menu. If the projector brand and model are not listed, check the Extron Web

site to see if a new driver is available or enter user‑deﬁned RS‑232 strings. See

“Advanced Projector Conﬁg” in chapter 4 of the User’s Manual for details.

3. Conﬁgure the buttons. Use the

drop‑down box associated with each

button to select the command to be

issued or function to perform, as

shown at right.

Each conﬁgured button has a green or red dot on it.

N If a button has been previously conﬁgured, it will have a red (IR) or

green (RS-232) dot to indicate that an IR or RS-232 code has been associated

with it.

4. Choose a volume control option. Select Projector if

planning to use the projector display speakers or if using

the projector display as a preamp. Select Switcher (MLS)

when using an external switcher as an audio preamp or

ampliﬁer.

Step 4 — IR learning

If there are no drivers available, the MLC can learn IR commands to control

projectors or other devices. IR learning is required to conﬁgure control modules to

control devices such as DVD players.

1. Select the third tab, Controller (MLC) Config.

2. Click on the appropriate button on the control module or the MLC to learn IR

codes.

N If a button has been previously conﬁgured, it will have a red (IR) or

green (RS-232) dot to indicate that an IR or RS-232 code has been associated

with it.

MLC 206 Setup Guide, cont’d

4. Click on OK to begin the learning process.

During IR learning hold the device remote control 4 inches to 14 inches

(10 cm to 36 cm) away from and directly in front of the MLC’s IR pickup

device.

Aim the remote

control at the MLC’s

IR pickup devices,

3. Click on the button labeled Learn IR to Button. A dialog box appears

indicating the button to which IR codes will be learned.

Once the IR commands have been successfully

learned, the button will be shown with a red dot

(shown at right) and the button/function may be

named.

5. Repeat steps 2 through 4 to set up additional buttons.

Step 5 — Completing the installation

1. Save the conﬁguration by selecting Save CONFIGURATION as..., and name it

appropriately.

2. Connect the MLC 206 to the projector for RS‑232 projector control.

a. Disconnect the power from the MLC (and the optional MediaLink Switcher,

if applicable) and from the projector.

b. Plug the 9‑pin D connector of the RS‑232 projector control cable (such as an

Extron UC 50’ cable) into the projector RS‑232 port. A cable adapter may be

required.

c. Connect the other end of the projector control cable to the MLC

Display/Source Control RS‑232 port. Wiring depends on the projector. See

the diagrams below and on page 8, and the pin assignments in the projector

user manual. Also see the display driver setup document available from

the download page of the Extron Web site.

N In most cases only the transmit (Tx), receive (Rx) and ground connections will

be needed. Wiring varies depending on the projector model.

and attach the head of each IR Emitter to an IR‑controlled device (VCR,

DVD player, projector).

N Place the IR emitter directly over the IR pickup device of the equipment.

to the MLC 206. Refer to chapter two of the MLC 206 User’s Manual and to the

accessory manual(s) for wiring diagrams and installation details.

5. Reconnect the power supply or optional MediaLink Switcher (MLS) to the

MLS/Power port and connect power to all controlled devices.

6. Verify the system operates correctly when selections and adjustments are made

at the front panel and/or from the User Mode section of the control software.

Adjust cabling or retry IR learning as needed.

7. Disconnect the host PC from the MLC 206, remove power from the MLC

(unplug the power supply or switcher), and label the inputs (see the

MLC 206 User’s Manual for details).
