Extron electronic MEDIALINK MLC 52 - Manual (Page 43)

3-15 MLC 52 Series MediaLink Controllers • Operation
• 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.
