Extron electronic MLC 52 manual Activation of LEDs during button configuring

Operation, cont’d

3. Press the button on the MLC that will store the IR code that you want the MLC to learn. The following takes place on the MLC:

•The front panel 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 it with the desired command. If no IR command is entered within 5 seconds, the button stops blinking.

•On the rear panel, the IR learning LED for the next button memory block

available for programming begins to blink. (See “IR learning indicators,” f in the “Rear panel/cable connections” section of chapter 2, “Installation,” for more information on the IR learning LEDs.)

The LED that indicates how many commands have been programmed onto the button illuminates and remains lit.

Activation of LEDs during button configuring

4. Hold the display device’s remote control 4 to 14 inches (10 to 36 cm) away from the MLC and point it at the MLC’s IR Transmit/Receive LEDs. Within 5 seconds of pressing the MLC button (step 3), press the button on the remote whose function you want the selected MLC button to learn. When the IR command has been learned successfully, the IR learning LEDs blink in rapid progression from the top to the bottom, then back to the top.

For repeating command codes, such as those that increment/decrement a function (for example, turning the volume up and down), hold the button on the projector remote control for at least 3 seconds.

If no IR command is detected within 5 seconds, the LEDs and the front panel button time out and stop blinking.

•If the IR code was learned, the rear panel LEDs blink rapidly in succession from the top down, then back up to the top.

•If the IR code was not learned, the rear panel LEDs blink in random order.

5. If you want to program another command to the same button (you can program up to four commands on one button), press the button again. The next IR learning LED on the rear panel begins flashing (for example, if you have already programmed two commands on this button, the third LED from the bottom flashes).

If you do not want to program additional commands on the button, repeat steps 3 and 4 for the next button that you want to program.

6. When you are finished programming buttons on the MLC, set configuration switch #1 on the rear panel to Off (down).
