DVD and VCR Control

The DVCM 50 can control a DVD player or a VCR by using IR. The DVCM must be conﬁ gured for DVD/VCR control in one of the following ways before it will send commands to the DVD player or the VCR:

The Windows-based conﬁ guration software can be used to conﬁ gure the

• DVCM 50 by enabling you to do either of the following:

Load Extron IR drivers appropriate for your DVD/VCR. An IR driver

ﬁ le can be loaded from the DVCM 50 software CD or downloaded from the Extron Web site (www.extron.com).

Restore a DVCM conﬁ guration that was set up previously, then saved to

a ﬁ le.

See chapter 5 and the Windows

on setting up the DVCM and for downloading, programming, or learning DVD/VCR control commands using the software.

IR commands can be entered directly from an IR remote control into the DVCM

• through IR learning. IR learning is convenient for installing new or updated commands into the DVCM in the ﬁ eld. It can be performed with or without the use of software.

A DVCM 50 can transfer/conﬁ gure (duplicate or clone its conﬁ guration) to

• another DVCM 50 via IR data transfer without the use of cables or software.

-based conﬁ guration software Help for details

PRELIMINARY

Conﬁ gurations are stored in non-volatile memory. Therefore, if the power to

the unit is interrupted, the DVCM retains its settings and conﬁ guration.

Front Panel Components

The DVCM 50 front panel contains 15 buttons for controlling the DVD and VCR. Each of these buttons can be programmed with up to four IR commands/functions. The front panel also contains a conﬁ guration port, through which the DVCM can be connected to a PC‘s RS-232 port to program the DVCM’s buttons, update ﬁ rmware, and save and restore the DVCM’s conﬁ guration to the PC. Finally, three LEDs on the front panel indicate the DVCM’s operating mode (DVD or VCR) and whether IR signals are being transmitted.

DVCM 50 • Conﬁ guration and Operation

DVD and VCR (mode selection) buttons — Use these buttons to switch the

DVCM 50 operating mode between DVD and VCR. After one of these buttons is pressed, the DVCM buttons issue commands that control only the device with which the button is labeled (DVD or VCR).

For example, if you press the DVD button, the DVCM switches to DVD mode. Subsequently, each DVCM button that you press issues one of its programmed DVD commands (to which only the DVD player responds). If the DVD player is a combination DVD/VCR, the DVCM sends only commands that activate the device’s DVD functions. If the DVCM is already in DVD mode, pressing its DVD button does not cause it to switch modes.

The DVD and VCR buttons each have four memory blocks that can be

programmed with commands. In addition, pressing either mode selection button always causes the DVCM to switch to the mode of the button that was pressed.

DVD indicator LED — This LED glows amber when the DVCM is in DVD

mode.

VCR indicator LED — This LED glows amber when the DVCM is in VCR

mode.

Tx (Transmission) LED — This green LED blinks while the DVCM is

transmitting IR commands. It also blinks when any programmed front panel button is pressed. If a button is held down, the Tx LED continues to blink until the button is released.

If a button that was not programmed is pressed, the Tx LED does not blink.

Conﬁ guration port — This port is used for system conﬁ guration and for

loading control ﬁ les into the DVCM. Commands can be received through this port from the PC, using Simple Instruction Set (SIS

Programming the DVCM 50 Using IR

The DVCM 50 can be programmed/conﬁ gured via IR by the following methods:

IR learning from your DVD or VCR remote control

•

IR data transfer from another DVCM 50 that has been conﬁ gured previously

•

DVCM 50 • Conﬁ guration and Operation

Conﬁ guring using IR Learning

You can conﬁ gure the DVCM 50 by using IR Learning, which does not require conﬁ guration software. By this method, you can program the functions on your DVD or VCR remote control into the buttons on the DVCM front panel.

To program the DVCM via IR Learning, follow these steps:

1. Apply power to the DVCM.

2. On the rear panel, set conﬁ guration switch #1 to On. All other switches

should be Off.

3. Press the DVD or VCR button to select the mode in which the button will be

programmed.

When you press the DVD or VCR mode button, the LED lights above the

button that you pressed, indicating that the front panel buttons will be programmed for that mode.

4. Press the button on the front panel that will store the IR code that you want

the DVCM to learn.

The following takes place on the DVCM rear panel:

5. Within 5 seconds, point the DVD or VCR remote control at the IR learning

sensors on the rear panel, and press the remote control button whose function you want the selected DVCM button to learn.

If the IR command is learned successfully, the IR Learning indicator LEDs

blink in rapid progression from the top to the bottom, then back to the top. (If the IR code that you entered results in an error, the buttons ﬂ ash randomly.)

For repeating command codes, such as those that increment/decrement a

function (for example, scanning up and down through the channels on a VCR in TV mode), hold the button on the DVD or VCR remote control for at least 3 seconds.

6. If you want to add another command to the same button (you can program

up to four commands on one button in each operating mode), press the same DVCM button again. The next Learning LED on the rear panel begins ﬂ ashing. For example, if you have already programmed two commands on this button, the third LED from the bottom ﬂ ashes. Repeat step 5 to add the desired command.

If you want to program commands onto another DVCM button, repeat steps 4

and 5 for the next button that you want to program.

DVCM 50 • Conﬁ guration and Operation

7. When you are ﬁ nished programming buttons, set conﬁ guration switch #1

on the rear panel to Off. Verify that the commands you entered have been learned by pressing the buttons that you programmed and observing the actions of the DVD/VCR.

It may be helpful to program all DVD functions ﬁ rst, then program all the

VCR functions.

Programming the DVD and VCR mode buttons

The procedure for programming commands onto the DVD and VCR buttons is the same as the procedure for programming the other buttons (see the previous section), except that you skip step 4. Pressing either of these buttons once accomplishes the following:

•

Places the DVCM in button’s mode (DVD or VCR, depending on which button was pressed).

•

Selects the button’s next available memory block for programming.

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. An example of a button macro application would be turning on multiple DVDs or VCRs by pressing one button, one time.

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 or Conﬁ guring using IR Learning, earlier in this chapter, 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 set to

On (up), 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.

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.

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 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.

4. Verify that the button’s commands were erased by pressing the button again.

If the commands have been erased, only LED #1 (the bottom LED) blinks; and the other LEDs are off.

5. Repeat steps 1 through 3 for any additional buttons that you want to erase.

When ﬁ nished, place switch #1 in the Off position (down).

To erase the commands from the DVD or the VCR button, press the button

twice: the ﬁ rst time to switch to the desired mode; the second time to erase the commands.

Conﬁ guring using IR data transfer

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.

1. Ensure that all conﬁ guration switches are set to Off (down) on both the

transmitting and the receiving units.

2. Apply power to both units.

3. 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.

DVCM 50 • Conﬁ guration and Operation

4. 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.)

Setting up transmitting and receiving units for wireless data transfer

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 the transmitting and the receiving 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 on the next page shows how each 25% percent increment of

transferred data is shown by the button indicator LEDs.

IR Link should not be connected to either the receiving unit or the transmitting

unit while IR data transfer is being performed.

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

DVCM to the Off (down) 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. The transfer process restarts.

Operating the DVCM 50 Using IR Remote Control

The optional hand-held IR 452 Remote Control can be used in conjunction with an optional IR Link or IRL 20 and the DVCM 50 to operate your VCR and/or DVD player. Each button on the IR 452 remote control, when pressed, sends an IR signal via the IR Link or IRL 20 that emulates the DVCM button with the same name. The DVCM then sends the command to the DVD/VCR.

1. Wire the IR Link to the DVCM 50 and mount it. (See Wiring for IR remote

control, in chapter 2, for IR Link and IRL 20 wiring instructions. See the IR Link User’s Guide or the IRL 20 User’s Manual for mounting instructions.)

2. Using IR Learning, IR data transfer, or the Windows-based conﬁ guration

software, program the buttons on the DVCM 50 with the commands that you want the IR 452 to be able to issue to the DVD/VCR. (See Programming

the DVCM 50 Using IR, earlier in this chapter, or Using the Windows Conﬁ guration Software in chapter 5, for button programming instructions.)

• The IR Link or IRL 20 relays the IR signal to the DVCM through the DVCM’s IR In port, to which the IR Link or IRL 20 is connected.

• The DVCM recognizes the signal it receives via the IR In port, and responds as if its own equivalent button were pressed, issuing the command to the DVD/VCR.

Setup operations on the DVCM 50 cannot be performed from the IR 452.

PRELIMINARY

Buttons on the IR 452 remote control

The buttons on the optional IR 452 Remote Control duplicate the DVCM 50’s front panel controls for normal operation. The DVCM responds to IR signals from the IR 452 as if the corresponding button were pressed on the DVCM.

The IR 452’s Display Power button and the VCR and DVD control buttons do not function until commands have been stored in the DVCM’s memory. The IR 452’s VCR buttons control the ﬁ rst (lowest address numbered) VCR connected to the DVCM. The DVD buttons control the ﬁ rst (lowest address numbered) DVD connected to the DVCM.

Commands are transmitted from the DVCM’s IR Out port via the IR Emitters to the DVD/VCR when the corresponding button is pressed on the IR 452 or on the DVCM’s front panel.

The following IR 452 buttons do not have equivalents and cannot activate

memory blocks on the DVCM 50: Power On, Power Off, Mute On, Mute Off, Vol S, Vol T, PC, and Video. These commands are used with the MLC 52 only.

Input Selection

Whichever input the MLC 104 is using, DVD or VCR, the DVCM 50 is in the equivalent mode. Conversely, whichever mode (DVD or VCR) the DVCM 50 is in, the MLC 104 is using the corresponding input. (For example, if the MLC 104 is using the DVD input, the DVCM 50 is in DVD mode, and vice versa.)

For this to occur, the MLC 104 and DVCM 50 must be connected as shown in the illustration above, and the buttons must be conﬁ gured correctly (see Setting up buttons for DVD and VCR selection, on the next page, for information on programming the MLC 104’s buttons).

Special Application, cont’d

When the MLC 104 is connected to the DVCM 50, you can select between the VCR and the DVD player by two methods:

Pressing an input button on the MLC 104

• Pressing the DVD or VCR button on the DVCM 50.

•

You do not need to press both an MLC 104 button and a DVCM button to

select the VCR or DVD player.

Setting up buttons for DVD and VCR selection

On the MLC 104, you must specify one pair of input buttons that will be used to select the VCR or the DVD player. You can select either buttons 1 and 2, or buttons 3 and 4 (you cannot use both pairs to select the DVD/VCR). Buttons 1 and 3 select DVD mode, and buttons 2 and 4 select VCR mode. Pressing these buttons activates the DVCM 50’s DVD or VCR buttons, which select the input device.

The DVD and VCR buttons on the DVCM 50 do not need to be speciﬁ ed or programmed

to select the DVD or VCR. These buttons are preset to switch the system to DVD and VCR mode when pressed, and their settings cannot be changed.

To select the DVD/VCR pair of input buttons, set conﬁ guration DIP switch #4 on the DVCM 50 rear panel as follows:

•

Place switch #4 in the Off (down) position to use button 1 to select the DVD and button 2 to select the VCR.

•

Place switch #4 in the On (up) position to use button 3 to select the DVD and button 4 to select the VCR.

Using the IR 452 to Control the DVCM 50 and the MLC 104

The MLC 104 can be controlled by the IR 452 via the DVCM 50 in conjunction with the IR Link or IRL 20.

In order to provide IR control of the MLC 104, you need the following components:

IR 452

• IR Link or IRL 20

• DVCM 50

•

Enabling IR 452 control of the MLC 104

To set up the MLC 104 for control by the IR 452, do the following:

1. Program the buttons on the MLC 104 and the DVCM 50 front panels with

the desired commands. (Refer to the MLC 104 User's Manual for instructions on programming its buttons. See chapters 3 and/or 5 for information on programming the DVCM 50 buttons.)

2. Connect the DVCM 50 rear panel host port to the MLC 104 rear panel host

port. (See Connecting the DVCM 50 to the MLC 104, earlier in this chapter.)

3. Connect the IR Link or the IRL 20 to the DVCM 50 rear panel. (See Wiring for

IR remote control, in chapter 2.)

4. Mount the MLC 104, the DVCM 50, and the IR Link or IRL 20 on a wall or

furniture as desired. (Refer to the mounting instructions in the MLC 104 User's Manual.)

PRELIMINARY

Controlling the MLC 104 with the IR 452

The IR 452 controls the MLC 104 through the IR Link or IRL 20 and the DVCM 50, which is connected to the MLC 104 rear panel host port.

IR 452 to MLC 104 communication process

The following occurs when you press a button on the IR 452:

1. An IR signal associated with the button goes from the IR 452 to the IR Link or

IRL 20, then to the DVCM.

2. The DVCM 50 interprets the IR signal and responds to it by sending the

appropriate SIS command to the MLC 104.

You do not need to program any buttons on the DVCM 50 for it to interpret the signals it

receives from the IR 452.

The DVCM 50 is conﬁ gured to automatically send commands to the MLC 104. No

additional conﬁ guration is needed to operate the DVCM with the MLC 104.

PRELIMINARY

For example, the ﬁ rst row of the table above shows that when you press the Power On button in the Display section of the IR 452, the signal sent to the DVCM 50 is interpreted as the SIS command 1P. This command is sent to the MLC 104 to activate the button that is labeled On (in the Projector section). The MLC 104 responds by issuing the command to the projector to turn on.

Once you have programmed and labeled the buttons on the MLC 104, you should relabel

the IR 452 buttons to indicate the commands they will initiate on the MLC 104. Refer to your IR 452 User’s Manual for information on labeling buttons on the remote control.

Muting and unmuting

The MLC 104 does not have buttons that control muting and unmuting on the display device. However, you can program Mute On and Mute Off commands onto the MLC 104 using the Global Conﬁ gurator (GC2) software. (Visit the Extron Web site at www.extron.com for information on ordering the GC2 software.)

Depending on the feature set of your display device, you can program the MLC 104 to mute/unmute the video, audio, or both.

To use the IR 452 to control muting/unmuting, press the Mute On or Mute Off button in the Display section. Pressing these buttons causes the DVCM 50 to send an SIS command (1M for Mute On button or 0M for Mute Off button) to the MLC 104, causing it to mute or unmute the display device.

About Extron drivers

Extron drivers are control ﬁ les (libraries) of Extron-created IR commands that are speciﬁ c to a particular DVD or VCR. When you install your DVCM 50 conﬁ guration software, you must also install the IR drivers, which also are provided on the software CD. Before using the conﬁ guration software to conﬁ gure the DVCM’s buttons, you must load the appropriate driver for your VCR or DVD player to the DVCM 50.

The DVCM 50 is compatible with IP Link IR drivers found on the IPL Driver

Package, version 6 or higher.

Pre-conﬁ gured control ﬁ les (drivers) should be used whenever possible. If no

driver is available for the DVD or VCR you want to control, it is possible to create your own driver via IR Learning (see Programming the DVCM 50 Using IR, in chapter 3).

Performing IR Learning via software

The DVCM 50 can “learn” commands from your VCR or DVD player’s remote control in order to control the VCR or DVD player. Using IR Learning, you can program command codes to each of the DVCM button’s four memory blocks.

Follow these steps to initiate IR Learning via the conﬁ guration program:

1. Set conﬁ guration DIP switch #1 on the DVCM rear panel to

2. Launch the DVCM 50 conﬁ guration software.

3. On the DVCM 50 DVD or VCR diagram on the Controller

4. Select the Cmd radio button for the memory block where you want the

Using emulation mode

The DVCM 50 conﬁ guration program features an emulation mode so that you can set up a DVCM system before equipment is available on site. You can save the emulated settings to a conﬁ guration ﬁ le, then load that conﬁ guration ﬁ le to the DVCM 50 when the actual equipment is available.

To operate in emulation mode, follow these steps:

1. Start the MLC 52/DVCM 50 conﬁ guration program.

2. On the Comm Port Selection screen, select the Emulate radio button, then

click OK.

Uploading ﬁ rmware

If the need arises, you can update the DVCM 50’s ﬁ rmware via RS-232. Visit the Extron Web site (www.extron.com), and check for ﬁ rmware updates, which you can download. After you have downloaded the new ﬁ rmware ﬁ le to your PC, follow these steps to upload it to your DVCM.

1. Launch the MLC 52/DVCM 50 conﬁ guration software and save the current

conﬁ guration. (See Saving and restoring the conﬁ guration, earlier in this chapter.)

Using Simple Instruction Set (SIS™) Commands

Simple Instruction set (SIS) commands can be entered on your PC to ﬁ nd out more information about the DVCM 50.

Host-to-DVCM communications

SIS commands consist of one or more characters per ﬁ eld. No special characters are required to begin or end a command sequence. When the DVCM determines that a command is valid, it executes the command and sends a response to the host device. All responses from the controller to the host end with a carriage return and a line feed (CR/LF = ), which signals the end of the response character string. A string is one or more characters.

DVCM-initiated messages

When a local event such as a front panel (or Extron switcher front panel) selection or adjustment takes place, the DVCM responds by sending a message to the host. No response is required from the host. The DVCM-initiated messages are listed here (underlined).

PRELIMINARY

Error responses

When the DVCM receives a valid SIS command, it executes the command and sends a response to the host device. If the DVCM is unable to execute the command because the command is invalid or it contains invalid parameters, it returns an error response to the host.

The error response codes and their descriptions are as follows: E10 – Invalid command E13 – Invalid value (Number is out of range.) E14 – Invalid for this conﬁ guration
