1IR learner/transmitter — These sensors allow for IR control of the MLC and for IR learning. The two LEDs (one for transmitting, one for receiving) send and receive IR signals, enabling the MLC to learn commands and clone configurations from another MLC. The IR remote control must be pointed directly at these LEDs for best results.
The MLC can “learn” IR commands in order to control the display device. IR learning of device control codes is necessary only if there are no
You can also perform IR learning via the
2Enable Macro LED — The LED located immediately above the four green IR LEDs is labeled E, for Enable Macro. This LED lights amber when you place a button in macro mode. (See “Setting up macros,” in chapter 3, “Operations.”)
3Configuration switches — When set to “on,” these DIP switches place the MLC in IR learning mode or data transfer mode, or disable IR repeats.
•Switch 1: Enables IR learning.
•Switch 2: Enables data transfer, such as cloning the MLC’s configuration onto another MLC 52 (see “Configuring using IR data transfer,” in chapter 3, “Operations”).
•Switch 3: Disables IR repeats during playback. For most applications, this switch is placed in the off position.
Switch 4 is not used.
4Volume control (VC faceplate only) connector — Connect this volume control connector to an amplifier such as the Extron MPA 122 or MPA 181T to enable the volume control knob on the MLC 52 to raise and lower the volume on the display device via the amplifier.
