Operation, cont’d
MLC 52 Series MediaLink Controllers • Operation 3-14
Using the IR Link with the
MLC 52 and the IR 452
• 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.)
3 . To operate a device using the
IR 452, point the remote
control directly at the IR Link
or IRL 20 signal pickup
window. The IR 452 has a
range of approximately 30'
(12 m) within 40 degrees on
either side of the axis (see the
illustration at right).
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.
