The DM-RMC-100 provides a convenient one-box interface solution to support a single display device as part of a complete DigitalMedia system. It functions as a DM CAT receiver and control interface, providing a single HDMI® output along with 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.

As the leader in HDMI and control system technologies, Crestron® has developed DigitalMedia, the first complete HD AV distribution system that takes HDMI to a higher level, and allows virtually any mix of AV sources to be distributed throughout the home, office, school, or virtually any other facility.

DigitalMedia distributes uncompressed digital video and audio signals up to 450 feet (137 m) using DM cable[1]. DigitalMedia thoughtfully manages all of the different signals and devices, matching each source's output to the capabilities of the selected display(s) without using scaling or compression. 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, supporting HDMI with HDCP, Deep Color and 3D, handling WUXGA computer resolutions and 1080p60 HDTV with multi-channel HD lossless audio—all through a single connection. The HDMI output can also handle DVI signals using an appropriate adapter or interface cable[2]. In addition, there are RS-232, IR, and Ethernet control ports provided for controlling the display device, plus two relays for screen and lift control, and a SENS input for connection of an optional current sensor or contact closure.

Multiple DM-RMC-100s may be installed to handle each display in a multi-room distribution system, all fed from a central DM-MD series switcher. Or, a single DM-RMC-100 can be fed straight from a DM-TX-100 or other DM CAT transmitter to provide a simple solution for extending a computer or AV signal to feed a single display. The connection to the switcher or transmitter requires just one DigitalMedia cable, with a potential cable length up to 450 feet[1]. In lieu of a central switcher, the DM-RMC-100's LAN port may be used to connect over Ethernet to a 2-Series control system if needed.

Keyboard/Mouse Extender
When connected to a DM-MD series switcher or DM-TX-100 transmitter, the DM-RMC-100 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 host device 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 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 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.

Low-Profile Installation
The DM-RMC-100 mounts to a standard 2-gang, 4" square, or UK electrical box, and sticks out only one inch from the wall surface. Connections to the display are all positioned along the bottom edge of the receiver, allowing cables to be dressed neatly without obstruction. The DM and LAN connection are made behind the unit within the electrical box. An array of indicators on the front of the DM-RMC-100 provide for easy setup and troubleshooting, verifying the status of connections and signal activity at a glance.

Please refer to the DigitalMedia Design Guide, Doc. #4789 for additional information.
