Setup Guide and in chapter 4 of this manual, then save the project and build 
and upload the confi guration to the MLC.
Working With Combination Source Devices
Many combination DVD-VCR players can output the video signals from both the 
video tape and the DVD parts on a single port. If you connect this single output 
to one input on a switcher (or projector), the switcher has no way to automatically 
know whether it receives input from the DVD or from the VCR; the switcher treats 
it as one input device and does not switch between the two. 
Available methods
There are several ways to work around the single-input limitation to make both the 
DVD and VCR media accessible to the switcher, including the following methods:
•
 Using separate source output ports on the DVD-VCR player
•  Using a distribution amplifi er with the switcher
•  Using separate IRCM control modules for DVD-VCR control
•  Using an IRCM-DV+ control module for DVD-VCR control
Using an IRCM-DV+ control module and one MLC input button 
for DVD-VCR control
If the combination DVD-VCR player has only one available output port and 
neither a distribution amplifi er nor a pair of control modules [(IRCM-DVD or 
IRCM-DVD+) and IRCM-VCR] is available for use, you can create a special 
confi guration to allow control via the MLC 226 IP or SCP 226 front panel and an 
optional IRCM-DV+.

IRCM-DV+
An IRCM-DV+ normally must be associated with two different MLC or projector 
inputs, one for the DVD half of the IRCM-DV+, one for the VCR half. However, in 
this installation example, both halves will be associated with the same input.
