balanced line level and S/PDIF digital audio. The HDMI input supports HDMI with
HDCP, handling WUXGA computer resolutions and 1080p60 HDTV with
multichannel lossless audio. The HDMI input can also handle DVI and DisplayPort
Multimode signals using an appropriate adapter or dongle2. The RGB input handles
analog RGB signals up to WUXGA 1920x1200 pixels, as well as component video
up to 1080p603. The multi-format BNC input also accepts component HDTV signals
up to 1080p60, as well as standard definition NTSC/PAL composite and S-video.
Dedicated audio inputs include two stereo balanced line level analog and one S/PDIF
coaxial digital.
Additional inputs are easily added at locations up to 450 feet (~137 m)1 away using
DM Transmitters. Three CAT-type DM inputs are provided on the DM-MD6X1,
accepting inputs from individual DM Transmitters as well as other DM switchers. A
single DM CAT output is provided to drive a DM Receiver/Room Controller at the
display location, or to feed another DM switcher. HDMI and analog audio outputs
are also included to feed a local video display and audio system. The analog stereo
output includes professional balanced terminals and programmable volume control.
DigitalMedia
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 cable1. 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.
1. For DigitalMedia CAT wiring, use DM-CBL DigitalMedia Cable. Up to two DM Repeaters (model
DM-DR, sold separately) may be required. Refer to the latest version of the Creston DigitalMedia
Design Guide (Doc. 4789) for complete wiring guidelines. It is available from the Crestron Web site
(www.crestron.com/dmresources).
2. HDMI requires an appropriate adapter or interface cable to accommodate a DVI or DisplayPort
Multimode signal. CBL-HD-DVI and CBL-DP-HD interface cables available separately.
3. The RGB input can accept component, composite, and S-video signals via direct interface to Crestron
MPS Series products, or through an appropriate adapter (all sold separately). Input sync detection is
not provided for composite or S-video signal types through the RGB connection.

Crestron DM-MD6X1 6X1 DigitalMedia™ Switcher
QuickSwitch HD®Technology
Crestron exclusive QuickSwitch HD®technology minimizes the annoying switching
latency that plagues typical HDMI switchers. QuickSwitch HD achieves very fast
switching of HDMI signals by maintaining a constant HDCP connection with each
HDMI device in the system, eliminating the need to re-authenticate each time a
different source is selected.
Keyboard/Mouse Extender
The DM-MD6X1 also functions as a keyboard/mouse extender and switcher,
allowing a computer or other USB HID-compliant host device connected to the
DM-MD6X1 to be controlled by a keyboard and mouse at the display location using
a DM-RMC-100-1 room controller (sold separately), or at a presenter’s location
using select DM transmitters.
EDID Format Management
The DM-MD6X1 allows for management of the EDID (Extended Display
Identification Data) information that passes between the display devices and input
sources in the system. Using Crestron Toolbox™ software, the format and resolution
capabilities of each device can be assessed and managed through the DM-MD6X1,
ensuring reliable operation by instructing sources to output only the resolutions and
formats that can be handled by the displays and system wiring.
CEC Embedded Device Control
The primary objective of every Crestron system is to enable precisely the control
desired for a seamless user experience. DigitalMedia provides 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 DM-MD6X1 provides a gateway for controlling AV devices
right through their HDMI connections, potentially eliminating the need for any
dedicated control wires or IR probes. Through proper CEC signal management,
DigitalMedia allows you to take control of each device in the system as you like.
Easy Setup
The DM-MD6X1 is designed to be placed on a shelf or mounted in an equipment
rack or lectern. The front panel provides basic operation right out of the box.
User-friendly setup and troubleshooting tools are provided via Crestron Toolbox
software, performing automatic input and output configuration while letting the
installer make intelligent design decisions along the way. The switcher even tests and
measures the length of each DM cable, automatically making the appropriate
calibrations for optimal signal transmission to each DM device.

6X1 DigitalMedia™ Switcher Crestron DM-MD6X1
A Digital Upgrade for Legacy Systems
The DM-MD6X1 also affords a perfect signal converter for integrating DigitalMedia
with analog-based systems like Crestron MPS, QuickMedia®, and the CEN-RGBHV
Series (all sold separately). A simple HD15 VGA cable connected between the
output of an MPS system and the input of the DM-MD6X1 allows every RGB,
component, S-video, and composite video input on the MPS to be converted to
DigitalMedia*. Analog audio is converted similarly through a simple balanced stereo
audio cable. The DM-MD6X1’s HDMI and DM inputs may also be used to expand
the input capabilities of the MPS system to handle digital AV sources, and its analog
audio output can easily be fed into any spare input on the MPS to allow the digital
audio signals to be amplified and controlled through the MPS system.
Applications
The following diagram shows a DM-MD6X1 in a lecture hall application.

4. For DigitalMedia CAT wiring, use DM-CBL DigitalMedia Cable. Up to two DM Repeaters (model
DM-DR, sold separately), may be required. Refer to the latest version of the Crestron DigitalMedia
Design Guide (Doc. 4789) for complete wiring guidelines.
5. The DM OUT port consists of two separate RJ-45 connectors labeled Dand M. The Dport carries
HDMI signal. The Mport carries data. Refer to the following table for the connector pinouts.

6. To determine which is pin 1 on the cable, hold the cable so the end of the eight pin modular jack is
facing away from you, with the clip down and copper side up. Pin 1 is on the far left.
7. The source gain compensation only has an effect on the analog audio output (AUDIO OUT) and has
no effect on the DM or HDMI outputs. In addition, the total gain at the output will never exceed 0 dB,
as the total output range is –80 dB to 0 dB. This signifies that a +10 dB input compensation will start
to decrease to 0 dB as the output volume increases from –10 dB to 0 dB.
8. DMNet wiring is not compatible with Cresnet wiring. DMNet wiring cannot be daisy chained.
9. Refer to the following table for the 24 A B G connector pinouts.
PIN # SIGNAL DESCRIPTION WIRE COLOR
G Ground DC Ground Black
B DMNet- DMNet Grey

10. If a DM switcher or other DM device is supplying power and is connected to a DM port of the
DM-MD6X1 or other DM midpoint, then the +24V wire between the DM device and the
DM-MD6X1 must be disconnected. The A B G wires must remain connected.
11. For external DMNet power, use a Crestron CNPWS-75, C2N-SPWS300 (both sold separately), or
other Cresnet power supply as required. Do not interconnect DMNet with Cresnet.

Setup
Network Wiring
When wiring the DM network, consider the following:
NOTE: DMNet wiring and Cresnet®wiring are not compatible.
•Use Crestron Certified Wire.
•Use Crestron power supplies for Crestron equipment.
•Provide sufficient power to the system.
CAUTION: Insufficient power can lead to unpredictable results or damage
to the equipment. Use the Crestron Power Calculator to help calculate how
much power is needed for the system (www.crestron.com/calculators).
•For DigitalMedia CAT wiring, use DM-CBL DigitalMedia Cable. Up to
two DM Repeaters (model DM-DR, sold separately) may be required. Refer
to the latest revision of the Crestron DigitalMedia Design Guide (Doc.
4789) for complete wiring guidelines.
The DM-MD6X1 can also use high-speed Ethernet for communications between the
device and a control system, computer, media server and other IP-based devices. For
general information on connecting Ethernet devices in a Crestron system, refer to the
latest version of the Crestron e-ControlReference Guide (Doc. 6052), which is
available from the Crestron Web site (www.crestron.com/manuals). For information
specifically related to Ethernet connectivity using DigitalMedia devices, refer to the
latest version of the Crestron IP Considerations Guide (Doc. 4579), which is also
available from the Crestron Web Site (www.crestron.com/dmresources).
HDCP Signal Path
Sources using HDCP limit the number of display devices it can transmit to while
simultaneously limiting the depth of devices in the signal path. Too many devices or
greater than allowed depth in a signal path (from source to display) may create
problems with displaying audio and video content. The HDCP specification states
that the maximum depth of devices between source and display is six. Some
examples are shown in the following diagrams.
