NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
Reorient or relocate the receiving antenna
Increase the separation between the equipment and receiver
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected
Consult the dealer or an experienced radio/TV technician for help
Industry Canada (IC) Compliance Statement

The DM-RMC-100-C provides a convenient one-box interface solution to support a
single display device as part of a complete Crestron
It functions as a DM 8G Shielded Twisted Pair (STP) receiver and control interface,
providing a single HDMI™ output along with Ethernet, RS-232, and IR
control ports. Its compact low-profile design allows the DM-RMC-100-C to be
installed discreetly behind a flat panel display or above a ceiling mounted projector.
It connects to the head end or source location via a single DM 8G shielded twisted
pair cable.

DigitalMedia™ (DM) system.
Features and Functions
• DigitalMedia receiver and display controller
• Low-profile surface mount design
• DM 8G STP input supports up to 330 feet (100 meters) cable length
• Provides one HDMI or DVI display output
• Enables device control via CEC, RS-232, IR, or Ethernet
• Can be powered via DM or a local power pack
• Affords a one-wire connection to a DM switcher or transmitter
1. All cable sold separately. The maximum DM 8G STP cable length is 330 feet (100 meters) using
DM-CBL-8G DigitalMedia 8G™ cable or 200 feet (61 meters) using DM-CBL-D DigitalMedia
D cable. Refer to the latest version of the Crestron
complete wiring guidelines. It is available from the Crestron website at www.crestron.com.
2. HDMI requires an appropriate adapter or interface cable to accommodate a DVI signal. CBL-HD-DVI
interface cable sold separately.
3. Power over DM requires connection to a DM 8G STP power sourcing device.
DigitalMedia 8G provides an eight gigabit AV distribution and control network.
DM 8G delivers a one-wire transport for moving high-definition video, audio, and
Ethernet over low-cost STP copper wire without any need for compression or
hardware repeaters. One eight-conductor shielded twisted pair cable (sold separately)
is required, supporting distances up to 330 feet (100 meters) using DM 8G cable or
200 feet (61 meters) using DM cable.
DigitalMedia manages all of the various AV signals and devices in your system,
matching each source’s output to the capabilities of the selected display(s) without
relying on scaling. Every signal is preserved in its native video resolution and audio
format, ensuring a pure, lossless signal path throughout.
Multimedia Display Interface
A single HDMI digital AV output port is provided on the DM-RMC-100-C,
supporting HDMI with Deep Color and HDCP, handling 1080p60 HDTV with
multi-channel HD lossless audio as well as WUXGA computer resolutions—all
through a single connection. The HDMI output can also handle DVI signals using an
appropriate adapter or interface cable.
ports are provided for control of the display device and other equipment.
A single cable connects the DM-RMC-100-C to a DM switcher or transmitter,
transporting video, audio, control, networking, and power signals through one RJ-45
connection.
a multi-room distribution system, all fed from a central DM switcher. Or, a single
DM-RMC-100-C can be fed straight from a DM 8G STP transmitter, affording a
very 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-C
includes a 10BASE-T/100BASE-TX Ethernet port, providing a convenient LAN
connection for a local network device.
Embedded Device Control
The DM-RMC-100-C includes built-in RS-232, IR, and Ethernet control ports to
allow programmable control of the display device connected to it. It can also provide
an alternative to these 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-C provides a gateway for controlling the
display device right through the HDMI connection, potentially eliminating the need
for any dedicated control wires or IR probes.
1. All cable sold separately. The maximum DM 8G STP cable length is 330 feet (100 meters) using
DM-CBL-8G DigitalMedia 8G™ cable or 200 feet (61 meters) using DM-CBL-D DigitalMedia

3. Power over DM requires connection to a DM 8G STP power sourcing device.
The DM-RMC-100-C conveniently mounts on a wall, ceiling, or other flat surface.
At just one inch deep, it fits easily behind a flat panel display or above a
ceiling-mounted projector. All connections and LED indicators are positioned on the
sides, ensuring optimal access and visibility for a clean, serviceable installation.
An array of indicators is provided for easy setup and troubleshooting, verifying the
status of connections and signal activity at a glance.
Applications
