The DM-RMC-200-C provides an advanced one-box interface solution for a single display device as part of a complete Crestron® DigitalMedia™ system. It functions as a DM 8G+™ receiver, video scaler, audio amplifier, and control interface, providing a single HDMI® output along with speaker and line level audio, plus Ethernet, USB HID, and a variety of control ports. In addition to DM 8G+, it is also compatible with HDBaseT™ specifications, allowing it to be connected directly to any HDBaseT compliant source. Built-in scaling allows the connected display to handle virtually any video signal. Its compact, low-profile design allows the DM-RMC-200-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 using a single CAT5e or Crestron DM 8G® cable.[1]

DigitalMedia 8G+™
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 8G+ is the latest generation of DM, providing a true one-wire transport for moving high-definition video, audio, and Ethernet over low-cost twisted-pair cable without any compression or repeaters. Engineered for ultra high-bandwidth and ultimate scalability, DM 8G+ handles uncompressed video beyond high-definition with support for HDCP, Deep Color, and 3D. Audio capabilities include support for high-bitrate 7.1 audio formats like Dolby® TrueHD and DTS-HD Master Audio™ as well as uncompressed linear PCM. All signals are transported over one 8-conductor twisted-pair cable, supporting distances up to 330 feet (100 m) using Crestron DM 8G Cable or CAT5e.[1]

Crestron DigitalMedia 8G+ technology is designed using HDBaseT Alliance specifications, ensuring interoperability with third-party HDBaseT products. Via its DM 8G+ input, the DM-RMC-200-C can be connected directly to any HDBaseT compliant source without requiring a DM transmitter. HDBaseT connectivity through the DM-RMC-200-C converges uncompressed full HD digital video, audio, Ethernet, and control signals through a single CAT5e or CAT6 cable over distances up to 328 ft (100m).

Multimedia Display Interface
A single HDMI digital AV output port is provided on the DM-RMC-200-C, supporting HD 1080p video and WUXGA computer signals with HDCP, Deep Color, 3D[2], 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[3].

Stereo audio outputs are also provided for directly driving a pair of speakers, or for connecting to line inputs on the display or a separate amplifier or AV receiver.

A single cable connects the DM-RMC-200-C to a DM switcher or transmitter, or to an HDBaseT source, transporting video, audio, control, and networking signals all through one simple RJ45 connection.[1] Multiple DM-RMC-200-Cs 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-200-C can be fed straight from a DM 8G+ transmitter, affording a simple solution for extending a computer or AV signal to a single display.

High-Definition Scaler
Through a distributed scaler approach, DigitalMedia truly delivers the most flexible and user-friendly solution for routing multiple disparate sources to many different display devices. By placing an independent high-performance scaler at every display device, DM ensures an optimal image on every screen no matter what sources are selected. Distributed scaling allows a high-res computer source to be viewed on any display in the building. It also allows a high-definition 3D source to be viewed on lower-resolution 2D displays without compromising the original signal, letting you share your theater's full HD 1080p 3D image with smaller, lesser displays in other rooms.

The DM-RMC-200-C accepts any video source from standard NTSC 480i to HD 1080p60 w/Deep Color, as well as computer sources from VGA to UXGA/WUXGA, and scales them perfectly to match the native resolution of your video display. A range of common output resolutions are supported to work with virtually any popular flat-panel display, projector, or computer monitor. Intelligent frame rate conversion enables support for 24p and PAL format sources, and 3D to 2D conversion allows 3D content to be fed simultaneously to separate 3D and 2D displays. Setup and use of the scaler is simplified through fully automatic operation utilizing the display's EDID[2,4].

A pair of DM-RMC-200-Cs can also be used to facilitate a dual-projector 3D setup, steering just the left eye portion of a 3D signal to one projector, and the right eye portion to the other. This is done using the scaler's 3D to 2D conversion mode, enabling 3D capability with scaling.

Video Wall Processing
The DM-RMC-200-C has another trick up its sleeve, providing zoom capability on its output to display just a portion of the source image. Using this feature, multiple units may be combined to configure a high-definition video wall composed of up to 16 individual displays. Configurations of 2x2, 3x2, 3x3, 4x3, or 4x4 are supported, and all that is required is a separate DM-RMC-200-C for each display, and a DM switcher with sufficient DM 8G+ outputs.

Audio Amplifier
The DM-RMC-200-C is equipped with stereo analog audio outputs, and a built-in 30 Watt stereo amplifier. The output volume is adjustable via a control system using a keypad, touch screen, or handheld remote. The amplifier provides plenty of power to drive a pair of local speakers, or use the line output to connect directly to an input on the display device, a pair of amplified speakers, or a local sound system.

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-200-C includes a 10/100 Ethernet port, providing a convenient LAN connection for a local network device.

Keyboard/Mouse Extender
The DM-RMC-200-C 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 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-200-C 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-200-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 emitters.

Two low-voltage relay ports are also included on the DM-RMC-200-C for control of a projection screen or lift. Also, there are two discrete digital input ports to accommodate room occupancy sensors, power sensors, or contact closures for enhanced automation and monitoring.

Low-Profile Installation
Its low-profile design makes the DM-RMC-200-C perfect for installation behind a flat panel display or above a ceiling mounted projector. It mounts to a standard 2-gang US, UK, or European electrical box using the mounting bracket provided. The bracket even includes a convenient holder for the external power pack, providing for a clean installation that protrudes a mere 1-5/8 inches (41 mm) from the mounting surface.

Connections for the display device are all positioned along the top and bottom of the unit for a clean, serviceable installation. The DigitalMedia and relay connections are provided on the rear panel within the electrical box. Speakers may be connected to either the top panel or the rear. One of the digital input control ports is located on the rear panel, with the other provided on the bottom. An array of indicators is provided on the front of the DM-RMC-200-C for easy setup and troubleshooting.
