IRCM-DV+ • Installation and Operation
Installation and Operation, cont’d
commands are sent to all devices (VCR, DVD, projector)
at the same time because the IR Emitters and/or
IR Broadcaster share the MLC’s Display/Source Control
IR port.
As a result it is not possible to separately control two or
more identical devices.
Testing/Troubleshooting
Before installing the control modules into the wall or furniture,
test the system to make sure that the connections are correct and
the modules are working correctly.
1. Connect the cables between the MLC and the control
module(s), connect IR Emitters or an IR Broadcaster to the
MLC, and connect a host computer to the MLC’s Config
port. If available, cable the A/V source devices to the
display device (projector), and connect the projector to the
MLC. Refer the MediaLink Controllers Manual for wiring
diagrams.
2. Connect the MLC to a 12VDC power source. Connect the
host computer, A/V source devices, and projector to a
power source and turn them on.
3. Start the MediaLink Control Program, and set up the control
module(s) and the MLC (for each button select or type in
RS-232 commands, or perform IR learning, and assign
VCR and DVD functions to specific MLC inputs). If the
control program does not recognize the IRCM-DV+, you
may have an older version of the control program.
To set up the IRCM-DV+ you must use MediaLink
Control Software version 2.0 or higher.
4. Select an MLC input button associated with the
IRCM-DV+. Press the buttons on the control module,
watch the module’s LEDs, and observe the item being
controlled by the module (VCR, DVD).
The corresponding MLC input must be selected (active)
before either part (DVD or VCR) of the IRCM-DV+ can
be activated and can control the DVD or VCR.
4A. If the TX LED does not light when a button is
pressed, check the captive screw connector wiring at
both the MLC and the control module. If the
conductor assignments are not the same at both ends,
the circuits may be damaged if power is applied to
the wrong pole, and the control module will not turn
on. Verify that the connectors are wired identically at
both ends of the cable.

4B. If power is present at the MLC, at the control
module, and at the VCR and DVD, but the VCR and/
or DVD does not respond when a button is pressed:
• The MLC’s firmware may be too old.
The MLC to which the IRCM-DV+ is connected must
have MLC firmware version 1.04 or higher in order to
recognize and work with the IRCM-DV+.
• Make sure the control module’s address DIP
switch settings are correct and that each module
has a unique address.
• Verify in the MediaLink control software that an
IR command has been “learned” for each button
on the IRCM, and make sure the IRCM-DV+ has
been associated with specific inputs on the MLC.
• Verify that an IR Emitter is connected to the MLC’s
Display/Source Control IR connector for each device
(VCR, DVD player) being controlled, or that an IR
Broadcaster is connected in lieu of IR Emitters.
All IR control signals are sent to all devices (video
sources, projector, etc.) at the same time even if two IR
Emitters or an IR Broadcaster are installed. The IR
sending devices share the same IR Display/Control port
on the MLC. As a result it is not possible to separately
control two or more identical devices.
The VCR and DVD buttons on the MediaLink remote
control (MLA-Remote) cannot control the IRCM-DV+.
5. Call the Extron S
3
Sales and Technical Support Hotline if
the item(s) being controlled still does (do) not respond
when the control module’s buttons are pressed.
