About the DVCM 50 DVD/VCR Control Module
The DVCM 50 DVD/VCR Control Module is a four-space Architectural Adapter 
Plate (AAP) module that is used for controlling DVDs and VCRs. It can be used 
with an MLC 52 or MLC 104 MediaLink Controller, or as a standalone control 
module, sending IR signals directly to the DVD or VCR. The DVCM 50 can be 
confi gured by the following methods:
  •  IR Learning from a DVD or VCR remote control
 •
  IR data transfer (beaming) from another DVCM that has been confi gured
  •  Using IR drivers that have been downloaded using the Extron’s Windows

based confi guration software program
Features
Standalone operation available — If desired, the DVCM 50 can be used as a 
standalone unit without connection to, or dependence on, a system switcher 
or MediaLink controller. 
Macro and toggle button modes — Each button can be set to send out multiple 
IR commands. A button confi gured for macro mode can issue up to four 
commands in sequence from a single button press. A button confi gured for 
toggle mode can issue up to four different commands, sending out a different 
command each time the button is pressed.
Front panel confi guration port — This serial port enables advanced confi guration, 
driver downloads, and fi rmware updates to be performed from the front 
panel without the need to remove the control module from its mounting. The 
optional Extron confi guration cable (part #70-335-01) connects the DVCM 50 
to the PC’s RS-232 port.
Three confi guration methods — The DVCM 50 can be confi gured easily using the 
following methods:
 •  IR Learning — Allows the DVCM 50 to be set up directly from the DVD or 
VCR remote control without the need for software.
 •  IR data transfer (“beaming”) — Duplicates complete confi guration 
information from one DVCM 50 to another without cables or software.
 •  Windows-based confi guration software — Combined with one of the many 
IR drivers available on the Extron Web site, Extron’s MLC 52/DVCM 50 
Control Program software provides fast and simple setup.
Front panel security lockout — Front panel lockout (executive mode) can be 
implemented if the DVCM 50 is installed in an unsecured environment where 
easy access is not desirable.
