DigitalMedia™ Card Interface
A very handy and versatile tool for enabling a variety of interface and control capabilities using DMC Series input cards.

The DMCI is a compact, rack-mountable enclosure designed to allow the use of a single DMC-Series DM Switcher Input Card to support a variety of interface functions. The DMCI is a perfect companion to Crestron HD-MD8X1 and HD-MD8X2 QuickSwitch HD™ HDMI switchers, allowing virtually any AV source to be connected and routed through the switcher as a fully-digital HDMI signal. A Cresnet connection is provided on the DMCI for integration with a Crestron control system.

Analog to HDMI Converter
All DMC input cards are equipped with HDMI outputs, making them ideal for converting other AV signals to HDMI. Just slide a DMC-VID-BNC or DMC-VID-RCA-A card into the DMCI and you're ready to convert analog video and audio signals to HDMI. Similarly, a DMC-VID-RCA-D card provides conversion for analog video signals accompanied by SPDIF digital audio, while RGB computer signals can be converted using the DMC-DVI card. The DMCI even detects the resolution and format of each input signal, and embeds it as EDID (Extended Display Identification Data) within the HDMI output signal.

DVI to HDMI Converter
While any HDMI input can ordinarily accommodate DVI sources with just a simple passive adapter, that arrangement does not include any support for audio signals. Loaded with a DMC-DVI card, the DMCI provides a simple means for merging DVI digital video and analog stereo audio into a single HDMI output.

HDMI Audio Extractor
HDMI provides a terrific one-wire solution for connecting an AV source or computer to a display or AV receiver, as long as you want the video and audio signals to stay together. But what if you need to break out the audio signal to feed a separate sound system input? A DMC-HD HDMI card provides a perfect solution, allowing audio to be extracted from the digital stream via its analog stereo output, while simultaneously allowing the full HDMI signal to pass through unaffected. Or to go even further, the DSP-enhanced DMC-HD-DSP card accepts HDMI signals containing multi-channel surround sound audio, providing a 2-channel down-mix signal at its analog stereo output, and allowing the choice of 2-channel or multi-channel audio at the HDMI output. Using either card, the analog output volume can be controlled through a control system using a touchpanel or keypad.

EDID Extractor
Do you need to know all the details about an AV signal, like its video resolution, frame-rate, color depth, and audio format? Through its Cresnet connection to a control system, the DMCI can report EDID information about any connected signal for viewing on a touchpanel, or for auto-configuring a display device.

CEC Embedded Device Control
The DMCI can provide an alternative to conventional IR and RS-232 device control by harnessing the CEC (Consumer Electronics Control) signal embedded in HDMI. Through its connection to the control system, the DMCI provides a gateway for controlling many devices right through their HDMI connections, potentially eliminating the need for any dedicated control wires or IR probes. Proper management of the CEC signal allows you to take control of each device as you like.

USB HID Mouse/Keyboard Extender
Select DMC cards feature a built-in USB HID (Human Interface Device) host port, allowing a local computer or other component to be controlled by a keyboard, mouse, or other USB HID device at a remote location. The USB mouse/keyboard signal is transmitted over Ethernet to the DMCI using a DM-RMC-100 Room Controller (sold separately), or any Crestron product with a USB HID device port and Ethernet access.

Rack Mount DM Receiver
Loaded with a DM CAT input card (DMC-CAT) or DM Fiber input card (DMC-F), the DMCI affords a DigitalMedia receiver solution that's perfect for installation in an equipment rack or AV cart, or as a portable display interface. In addition to providing a single HDMI digital AV output, both cards feature an analog stereo audio output with programmable volume control.

Technical notes: 

USB console requires installation of a card with a USB port (e.g., DMC-HD).

† Connecting DMNet devices (e.g., a DM transmitter or repeater) to any card containing a DMNet port (e.g., DMC-CAT) will increase the total Cresnet Power Usage for the DMCI by the combined DMNet Power Usage of those DMNet devices. The maximum power available for DMNet devices is 63 Watts assuming a 75 Watt Cresnet power source.

‡ As tested with DMC-HD-DSP card installed.
