Extron electronic MLC 52 manual Buttons on the IR 452 remote control

•The MLC recognizes the command it receives via the IR IN pole, and responds as if its own equivalent button were pressed, issuing the command to the appropriate device.

See “Wiring an IR Link” in chapter 2, “Installation,” for information on wiring the IR Link. See “Wiring the IRL 20,” also in chapter 2, for information on connecting the IRL 20 signal receiver.

Setup operations cannot be performed from the IR 452 remote control.

Buttons on the IR 452 remote control

The buttons on the optional IR 452 Remote Control duplicate the MLC 52’s front panel controls for normal operation. The MLC responds to commands from the IR 452 as if the corresponding button were pressed on the controller.

From a distance of no more than 30 feet and within 40 degrees of the axis, the IR 452 sends infrared (IR) signals to an MLC 52 via the optional IR Link or IRL 20.

MLC 52 configuration cannot be performed from the IR 452.

The IR 452’s Display Power On and Power Off buttons and the VCR and DVD control buttons cannot control a device through the MLC until commands have been stored in the MLC’s memory. The IR 452’s VCR buttons control the first (lowest address numbered) VCR connected to the MLC, while the DVD buttons control the first (lowest address numbered) DVD connected to the MLC.

The IR 452 cannot control the volume knob 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.

Commands are transmitted from the MLC’s control connector (via hard wiring) and IR ports (via IR Emitters or the optional

IR Broadcaster) when the corresponding button is pressed on the IR 452 or on the controller’s front panel.
