  • Page 20 Wiring an IRL 20 The Extron IRL 20 is a hard wired IR signal receiver that can be used with the MLC 52 and an IR remote control. The IRL 20 receives a signal via its front panel (or an IR sensor) from the IR remote control, and outputs a modulated IR signal via an IR emitter.

  • Page 21: Wiring The Power Connector

    Wiring the Power Connector The control connector also contains a power connector for the MLC 52. Connect the supplied external 12 VDC, 1 A power supply to this port to power the MLC as shown in the following diagram. The Extron PS 1210 (included) and other Extron power supplies can be used NOTE: with the MLC 52.
  • Page 22 To transmit configuration data via IR, both the transferring and the receiving MLCs must be removed from the wall, electrical box, or furniture, and both must be powered on. The MLC that is already configured can be powered by an external power supply, or it can share a power supply with the unit that will be configured.
  • Page 23 The front panel buttons act as data transfer progress indicators. While data is being transferred, the buttons on both the transmitting and the receiving MLCs blink sequentially in clockwise order, starting with the On button in the upper-left corner (see figure 16). This cycle repeats until transfer is complete. DISPLAY DISPLAY VOLUME...

  • Page 24: Configuring Using Ir Learning

    When the data transfer is complete, do either of the following: If you want to repeat the transfer process to configure another MLC 52, repeat • steps 2 and 3 for the unit that is to be configured. Press any button on the donor unit.

  • Page 25: Removing Ir Commands From A Button

    Hold the remote control of the display device between 4 and 14 inches (10 to 36 cm) away from the MLC and point it at the IR Transmit/Receive LEDs on the MLC. Within 5 seconds of pressing the MLC button (step 3), press the button on the remote control whose function you want the selected MLC button to learn.

  • Page 26: Setting Up Button Macros Using Ir

    Setting Up Button Macros Using IR Buttons function in either toggle mode or macro mode. By default, all the buttons (except the On and Off Display buttons) are in toggle mode. This means that each press of the button issues one command — the next in sequence of the four commands programmed to the button (each button can store up to four commands).

  • Page 27: Setting Up An Mlc 52 Vc Model With An Extron Amplifier

    Press the MLC button that will store the input selection IR codes. The button blinks for 5 seconds, during which time it is able to learn codes. On the rear panel, the first (bottom) IR learning LED starts flashing.) If a command is not entered within 5 seconds, the button and LED stop blinking, and you must press the button again to put it in back in learning mode.

Through this port, the MLC receives commands issued via the configuration software on your computer. Use a 2.5 mm TRS to 9-pin D-sub connector cable to connect the MLC to your PC via this 2.5 mm female TRS (tip-ring-sleeve) connector.
  • Page 37 Selecting Inputs The four buttons below the On and Off buttons on the front panel can be configured to select inputs on the display device. The PC and Video buttons have been preconfigured to select inputs — a desktop or laptop computer (PC); a VCR or DVD (Video). Using IR learning, IR data transfer, or the MLC 52 configuration software, you can reconfigure these buttons and add commands to them to select other inputs if desired.

  • Page 38: Resetting

    Resetting In the event that the MLC 52 needs to be reset, you can do so by one of the following methods: • Factory firmware reset — Press and hold the bottom right button (the Video button on standard models or the blank button on VC models) while applying power to the MLC.

  • Page 39: Special Applications

    Special Applications This section describes some special types of applications that represent unique conditions. For the MLC 52 to operate properly in these situations, it is important that the controller be configured correctly. In this section, three application examples are described, along with their requirements for the MLC 52.

  • Page 40: Programming Buttons For An Ir Controlled System

    The MLC 52 is configured differently depending on the type of projector remote control that will be used and on whether the MLC will use IR or RS-232 projector control. Because each button on the MLC 52 can store up to four commands per button, the PC and Video buttons should be programmed as shown in the illustrations below and on the following pages.
  • Page 41 Projector remote control type A (application 1) This remote control has a discrete button for each input. Two buttons are designated for RGB inputs, one for S-video, and one for video (composite). • Use IR learning to program the command from each of the projector remote control RGB input selection buttons onto the MLC PC button.
