Configuration and Operation DVD and VCR Control The DVCM 50 can control a DVD player or a VCR by using IR. The DVCM must be configured 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 configuration software can be used to configure the DVCM 50 by enabling you to do either of the following: o Load Extron IR drivers appropriate for your DVD/VCR.
1 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).
Configuration and Operation, cont’d 6 DVD and VCR control buttons — These buttons may be used to control both a DVD and a VCR. The buttons can be programmed via IR Learning, data transfer, or the Windows-based configuration software to perform the functions for which they are labeled. Each of these buttons has eight memory blocks (four available in DVD mode and four for VCR mode), which can be programmed with commands.
Configuring using IR Learning You can configure the DVCM 50 by using IR Learning, which does not require configuration 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 configuration switch #1 to On. All other switches should be Off. 3.
Configuration and Operation, cont’d The following buttons cannot be programmed in VCR mode. The DVCM must be in DVD mode to program them. Title Menu Enter Right X (Tuner) Left W (Tuner) The TV/VCR button cannot be programmed in DVD mode. It can be programmed only in VCR mode. If you press a button that does not function in the current mode, the button’s orange indicator LED(s) blink three times, indicating that the button cannot be programmed.
7. When you are finished programming buttons, set configuration 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 first, then program all the VCR functions.
Configuration and Operation, cont’d Taking a button out of macro mode To take a button out of macro mode, follow these steps: 1. Place configuration 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 confirm that the orange E LED has turned off, indicating the button is no longer in macro mode. 4. Set Configuration switch #1 to Off.
4. On the DVCM that will receive the data, set configuration 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).
