DVCM 50 Control Module Quick Start Guide

The DVCM 50 DVD/VCR Control Module is a four-space Architectural Adapter
Plate (AAP) module that is used for controlling DVDs and VCRs. It can be used
with an MLC 52 or MLC 104 MediaLink Controller, or as a standalone control
module, sending IR signals directly to the DVD or VCR. The DVCM 50 can be
confi gured by the following methods:

• IR learning from a DVD or VCR remote control

• IR data transfer (beaming) from another DVCM that has been confi gured

• Using IR drivers via the Extron’s Windows
program

The DVCM 50 DVD/VCR Control Module Quick Start Guide is designed to give you
an overview of what you need to do to set up and operate your DVCM 50, and to
help you quickly get started using it. For more details regarding the installation,
operation, and confi guration of the DVCM 50, refer to the DVCM 50 User’s Manual,
provided on CD with your DVCM.

DVCM 50 • Quick Start Guide

Setting up button macros

DVCM 50 buttons function in either toggle mode or macro mode. By default, the
buttons are in toggle mode, which means that each press of the button initiates one
of the commands saved 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.

To put a button in macro mode, follow these steps:

1. Ensure that power is applied to the DVCM 50.

2. Set confi guration switch #1 on the rear panel to On (up).

3. Program the buttons with the desired commands. See Confi guring using IR

data transfer, later in this guide, or Confi guring using IR learning, earlier in this
section, for programming procedures.

4. To put the button in macro mode, press and hold it for 3 seconds. The orange
LED above the learning indicator LEDs, labeled “E” on the back panel, fl ashes
rapidly fi ve times, then turns off, indicating that the button is now confi gured
for macro mode. Release the button.

The next time that the button is pressed while confi guration switch #1 is in

the On (up) position, the orange E LED lights, indicating that the button is in
macro mode.

5. Set confi guration switch #1 to Off (down). 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.

Taking a button out of macro mode

To take a button out of macro mode, follow these steps:

1. Place confi guration switch #1 on the rear panel in the On (up) position.

2. Press and hold the button that is in macro mode for 3 seconds. The orange E

LED blinks three times, then turns off.

3. Press the button again to confi rm that the orange E LED has turned off,
indicating the button is no longer in macro mode.

4. Set Confi guration switch #1 to Off (down).

Commands that have been programmed on the button are not erased when the

button is taken out of macro mode.

Removing 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. Follow these steps:

1. While the DVCM 50 is powered on, set confi guration switch #1 to On (up).

2. Press the DVD or VCR button to place the DVCM in the mode in which you

want the commands to be erased.

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

Example: If you want to erase the DVD player’s Play function from its Play

button, fi rst press the DVD button to ensure that the DVCM is in DVD mode.
Then, erase the Play function (and all other functions) from the Play button by
pressing it twice within 2 seconds.

You can also confi gure your DVCM 50 by transferring button confi guration data to
it from another confi gured DVCM 50 via the two IR LEDs on the back panels of the
DVCMs. With this method, you replicate (clone) the other DVCM’s confi guration
on your own unit without the use of software or cables.

To transmit confi guration data via IR, both the transferring and the receiving
DVCMs must be free of the wall, electrical box, or furniture. The DVCM that is
already confi gured must be powered by an external power supply, or by a power
supply shared with the unit that will be confi gured.

Step 1

Ensure that all confi guration switches are set to Off (down) on both the
transmitting and the receiving units.

Step 2

Step 3

Step 4

Apply power to both units.

Align the two units so that the IR Transmit and Receive LEDs of both DVCMs
are facing each other, and between 1 and 2 inches apart.

On the DVCM that will receive the data, set confi guration switch #2 to On (up),

and all others to Off (down). (See the illustration below.) Leave all switches on the
transmitting unit (the donor unit) set to Off (down).

Setting up transmitting and receiving units for IR data transfer

DVCM 50 • Quick Start Guide

The data transfer begins when the receiving unit detects the transmitting unit,

and the process takes 15 to 20 seconds to complete. (It may take longer if the
transmitting unit has multiple commands programmed on each button.)

The button indicator LEDs on the rear panel act as data transfer progress

indicators. While data is being transferred, these LEDs on both DVCMs light to
indicate the amount of data that has been transferred.

After approximately 25% of the data has been transferred, the fi rst LED on
the right lights and remains lit. After another 50% has been transferred, the
second LED from the right lights. After 75% of the data is transferred, the
third LED from the right lights, and when the transfer is complete, all four
LEDS are lit.

The table below shows how each 25% increment of transferred data is shown

by the button indicator LEDs.

When the transfer is complete, all the button indicator LEDs remain lit.

Proceed to step 5.

If the transmission is interrupted (for example, the two units become

separated so that the IR LEDs are no longer in direct line of sight of each
other), and the conditions necessary for transfer are then restored, the two
units restart the transfer process.

Step 5

When data transfer is complete, do either of the following:

If fi nished confi guring, return confi guration switch #2 on the receiving

•

DVCM to the Off position. Press any button on both units to return them

to the state they were in before the transfer. Reinitialize the receiving unit by
pressing any of its front panel buttons.

If you want to repeat the transfer process to confi gure another DVCM 50,

•

repeat steps 3 and 4 for the unit that is to be confi gured. Press any button on

the transmitting unit to restart the transfer process.

Confi guring using the Windows-based confi guration software

The DVCM 50 can be remotely confi gured via a host computer connected to the
front panel confi guration port. Through this port, you can program the DVCM’s
buttons with commands by using the Windows-based confi guration software
(DVCM 50/DVCM 50 Control Program). The optional 9-pin D to 2.5 mm stereo
mini TRS RS-232 cable (part #70-335-01) can be used for this connection.

The cable has the following pin assignments:

Installing the software

Extron’s MLC 52/DVCM 50 Control Program Windows-based confi guration
software, provided on a CD that is included with your DVCM 50, provides a
convenient way to program all the DVCM buttons, in both DVD and VCR mode.
This confi guration program’s graphical user interface includes the same functions
as those on the DVCM’s front panel, plus the ability to use IR drivers for a wide
range of A/V devices.

12

This software program only confi gures the DVCM 52 buttons. It does not

control the DVCM itself. In other words, you are not able to click buttons on
the screen to make the DVCM switch modes, start or stop the VCR, etc.

To install and run the DVCM 50 confi guration program software, ensure that your
PC meets the following minimum requirements:

• Windows 2000, XP, or higher

• 400 MHz processor

• 32 MB free hard disk space
Updates to the software can be downloaded from the Extron Web site

(http://www.extron.com).
In order to use the confi guration software with the DVCM, your PC must

be connected to the DVCM 50 front panel confi guration port by the optional
9D-2.5 mm TRS serial cable, described above.

DVCM 50 • Quick Start Guide

The installation process has two parts: installing the software and installing the IP
(IR) drivers. The fi les you will install need approximately 32 MB (megabytes) of
total of hard disk space.

To install the software and IR drivers onto the PC hard drive, follow these steps.

Step 1

Insert the CD ROM into your CD drive. The disk should start automatically. If it
does not, run LAUNCH.EXE from the CD.

Step 2

Click Install Program on the Software Installation screen.

Step 5

Follow the instructions on the InstallShield Wizard screens to complete the
program installation.

By default the installation creates a directory called “MediaLink” on the PC hard
drive, and places the following two icons in it:

• MediaLnk52.exe (MediaLink confi guration program)

• MediaLnk52.hlp (MediaLink Help program)

Step 6

Return to the Software Installation screen, and click Extron IP Link Drivers.

Step 7

Click Run on the File Download window that opens, then click Run again on the
Security prompt window.

Step 8

Follow the instructions on the Driver InstallShield Wizard screens to complete
the driver installation.

By default, the installation places a folder called Driver 2 containing the set of IR
drivers in the Extron folder under Program Files. If your Program Files folder does
not contain an Extron folder, the installer creates that as well.
