MLC 52 Series Quick Start Guide About the MLC 52 Series The Extron MediaLink™ Controller 52 (MLC 52) provides infrared (IR) and/or RS-232 remote control of a projector or other display device. It is an economical, compact (one-gang size), easy-to-use controller designed for use with audiovisual equipment in sites such as an elementary or high school classroom, or a small conference room.
MLC 52 Series Quick Start Guide, cont’d MLC 52 VC models with volume control faceplate The two-gang sized MLC 52 IR VC and MLC 52 RS VC each have a projector volume control knob in addition to the six control buttons. To use this knob, you must connect the MLC 52 to an Extron MPA Series Mini Power Amplifier (sold separately), to which you can also connect the projector (see the application diagram below).
Installing the MLC 52 The MLC can be installed into a wall or furniture. Follow the instructions appropriate to the mounting option you have selected. Step 1 Prepare the installation site as required for your MLC model (cut a hole in the wall or furniture, and install an electric wall box and/or mounting bracket). See “Mounting an electrical box” in chapter 2, “Installation,” of your MLC 52 User’s Manual, for details on this procedure. a.

The ports in this connector, from left to right, perform the following functions: F (Tx) — Transmits the RS-232 signal for projector control. This port is present on all models, but it is active only on the RS models. E (IR OUT) — Used for connecting an IR Emitter to issue IR commands. Up to two emitters can be wired to this port.
b. Wire the RS-232 (Tx) port (RS models only). If you have an RS model and want to control the projector via RS-232, connect a cable between the projector and this 3.5 mm, 6-pole direct insertion captive screw connector. Use the following illustration as a guide. Refer to “Wiring for RS-232 control” in chapter 2, “Installation,” of your MLC 52 User’s Manual, for details on cable pin assignments and the wiring procedure.

MLC 52 Series Quick Start Guide, cont’d Step 3 Press the button on the MLC front panel that will store the IR code that you want the MLC to learn. The following takes place on the MLC: • The button that you pressed begins to blink, indicating that it is ready to be programmed. While the button is blinking (5 seconds), you can program the button with the desired command. • On the rear panel, the IR Learning LED that indicates the button memory block currently available for programming begins to blink.
Step 6 When 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. Removing commands from a button If you want to delete one or more commands that have been programmed onto a button, you must remove all the commands programmed to that button. Follow these steps: 1.

This continues until the transfer process is complete and all buttons are permanently lit. By observing how many buttons are lit steadily, you can see approximately how much data has been transferred. The buttons on the MLC VC models blink in the same pattern as the standard models.
