The DM-RMC-100 provides a convenient one-box interface solution for
a single display device as part of a complete Crestron® DigitalMedia™
system. It functions as a DM® CAT receiver and control interface, providing
a single HDMI® output along with Ethernet, USB HID, and a variety of
control ports. Its compact, low-profile design allows the DM-RMC-100
to be installed discreetly behind a flat panel display or above a ceiling
mounted projector. It connects to the head end or source location using a
single Crestron DM® cable.[1]
As the leader in HDMI and control system technologies, Crestron developed
DigitalMedia (DM) to deliver the first complete HD AV distribution system to
take HDMI to a higher level. DigitalMedia allows virtually any mix of HDMI
and other AV sources to be distributed throughout a home, office, school,
or virtually any other facility. DigitalMedia CAT distributes uncompressed
digital video and audio signals up to 450 feet (137 m) using Crestron
DM cable[1].
Multimedia Display Interface
A single HDMI digital AV output port is provided on the DM-RMC-100,
supporting HD 1080p60 video and WUXGA computer signals with HDCP,
Deep Color, 3D, and multi-channel HD lossless audio — all through one
connection. The HDMI output can also handle DVI signals using an
appropriate adapter or interface cable[2].
A single DM cable connects the DM-RMC-100 to a DM switcher or
transmitter.[1] Multiple DM-RMC-100s may be installed to handle each
display in a multiroom distribution system, all fed from a central DM-MD
series switcher. Or, a single DM-RMC-100 can be fed straight from a
DM CAT transmitter to provide a simple solution for extending a computer
or AV signal to a single display.
LAN Connectivity
Along with high-definition AV and control, DigitalMedia also integrates
high-speed Ethernet networking for a total signal distribution solution. The
DM-RMC-100 includes a 10/100 Ethernet port, providing a convenient LAN
connection for a local network device.

Keyboard/Mouse Extender
The DM-RMC-100 also functions as a keyboard/mouse extender, allowing
a USB HID-compliant keyboard and/or mouse to be connected at the
display location, and used to control a computer or other component
located at the central equipment rack or some other remote location.
Embedded Device Control
The primary objective of every Crestron system is to enable precisely the
control desired for a seamless user experience. The DM-RMC-100 includes
built-in RS-232, IR, and Ethernet control ports to allow programmable
control of the display device connected to it. But, it can also provide an
alternative to such conventional control methods by harnessing the CEC
(Consumer Electronics Control) signal embedded in HDMI. Through its
connection to the control system, the DM-RMC-100 provides a gateway for
controlling the display device right through the HDMI connection,
potentially eliminating the need for any dedicated control wires or
IR emitters.
Two low-voltage relay ports are also included on the DM-RMC-100 for
control of a projection screen or lift. In addition, a single digital input port is
provided to accommodate a power sensor or contact closure for enhanced
automation and monitoring.
Low-Profile Installation
Its low-profile design makes the DM-RMC-100 perfect for installation
behind a flat panel display or above a ceiling mounted projector. It mounts
to a standard 2-gang, 4” square, or UK electrical box using the
mounting bracket provided, affording a clean installation that protrudes a
mere 1-1/8” inches from the mounting surface.
Connections for the display are all positioned along the bottom of the unit
for a clean, serviceable installation. The DM and LAN connections are
provided on the rear panel within the electrical box. An array of indicators
is provided on the front panel for easy setup and troubleshooting.
