Operation, cont’d

•If an input selection button is in macro mode, pressing the button once executes all the commands stored on that button, in memory block order (i.e., the command in memory block 1 is performed first, then block 2, etc.). See “Setting up button macros,” earlier in this chapter, for more information.

Operating the MLC 52 Using IR Remote Control

The MLC 52’s optional hand-held IR 452 remote control can be used in conjunction with the MLC 52 to operate your projector, plasma display, and input devices. The IR 452 remote control is delivered with commands for a variety of device functions (for example, VCR On, VCR Off, Stop, Pause). These commands can be programmed onto the MLC’s buttons only via the Windows-based configuration software. (See “Assigning functions to buttons” in chapter 5, “Serial Communication.”

The IR 452 cannot perform the volume knob’s function on the MLC 52 IR VC or the MLC 52 RS VC. All other functions on the IR 452 are available on the MLC 52 VC models.

The IR 452 remote control also requires the optional IR Link or IRL 20 in order to send commands to the MLC, which in turn issues the commands to the input or output devices.

1.Wire the IR Link or IRL 20 to the MLC 52 and mount it. (See “Wiring for IR remote control” or “Wiring the IRL 20,” in chapter 2, for IR Link or IRL 20 wiring instructions. See the IR Link or the IRL 20 user’s guide for mounting instructions.)

2. Using the MLC 52 Windows-based configuration software, program the desired buttons on the IR 452 with the commands available with the currently loaded driver.

(See “Assigning functions to buttons” in chapter 5, “Serial Communication,” for button programming instructions.)

4. Press the button for the function you want to perform. The following takes place:

•The remote control sends the pressed button’s programmed command via infrared (IR) signal to the IR Link or IRL 20.

•The IR Link or IRL 20 sends the command to the MLC through the MLC’s IR IN pole on the control connector, to which the

IR Link or IRL 20 is connected.

Total distance from MLC is 150' (45.7 m) max.
