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 meters) 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.
Multimedia Computer/AV Interface
The DM-TX-200-2G provides simple switching between two inputs. The
DM-TX-400-3G provides versatile switching between four different video and audio
inputs. The HDMI input supports HDCP and handles WUXGA computer resolutions
and 1080p60 HDTV with multi-channel lossless audio. The HDMI input can also
handle DVI and DisplayPort Multimode signals using an appropriate adapter or
dongle2. The RGB input handles all analog RGB signals up to WUXGA 1920x1200
pixels, as well as component video up to 1080p603. A mini-TRS stereo audio input is
also provided to accept analog audio signals from an unbalanced line-level or
headphone output. On the DM-TX-400-3G, both digital and analog audio signals are
supported via HDMI, S/PDIF, and RCA inputs.
Used with a single DM-RMC-100 Room Controller and optional Crestron Control
System (both sold separately), the DM-TX-300-2G and DM-TX-400-3G afford very
simple solutions for extending a multimedia computer or AV signal to a single
display up to 450 feet (137 m) away1. As part of a larger system using a DM-MD
series switcher, multiple DM-TX-200-2G and DM-TX-400-3Gs may be installed to
enable the distribution of several sources at different locations to feed multiple
displays throughout any room or larger facility.
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 Crestron DigitalMedia
Design Guide (Doc. 4789) for complete wiring guidelines.
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 (not included). Input sync detection
is not provided for composite or S-video signal types through the RGB connection.

Crestron DM-TX-200-2G/400-3G Wall Plate DigitalMedia™ CAT Transmitters
Keyboard/Mouse Extender
When connected to a DM-MD series switcher, the DM-TX-200-2G and
DM-TX-400-3G function as keyboard/mouse extenders, allowing a USB HID
(Human Interface Device) compliant keyboard and/or mouse at the podium or
conference table to control a computer or other host device located at the central
equipment rack.
EDID Format Management
The DM-TX-200-2G and DM-TX-400-3G allow 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-TX-200-2G or DM-TX-400-3G, 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-TX-200-2G or DM-TX-400-3G provides a gateway for
controlling the connected source device right through the HDMI connection,
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.
Simple Wall Mount Design
The DM-TX-200-2G and DM-TX-400-3G are designed to be wall mounted using a
standard electrical box or plaster ring. The DM cable is terminated at the rear of the
transmitter using screw terminals. An array of indicators on the front of the
DM-TX-200-2G and DM-TX-400-3G provide for easy setup and troubleshooting,
verifying the status of connections and signal activity at a glance. Advanced
configuration is enabled through Crestron Toolbox software.
A Digital Upgrade for Legacy Systems
The DM-TX-200-2G and DM-TX-400-3G also afford perfect signal converters 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-TX-200-2G or DM-TX-400-3G 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 unbalanced stereo audio cable. The
HDMI input may also be used to expand the input capabilities of the MPS system to
handle digital AV sources.
* The RGB input can accept component, composite, and S-video signals via direct interface to
Crestron MPS Series products, or through an appropriate adapter (not included). Input sync detection
is not provided for composite or S-video signal types through the RGB connection.

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. Please 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 version of the Crestron DigitalMedia Design Guide (Doc. 4789)
for complete wiring guidelines.
For more details, refer to “Check Network Wiring” on page 34.
Identity Code
NOTE: In the SIMPL™ Windows program, when a DM-TX-200-2G or
DM-TX-400-3G is dropped onto an input card of a DM switcher, its IP ID is
assigned automatically and does not require additional programming. Use the
information below when a DM-TX-200-2G or DM-TX-400-3G is dropped directly
into an Ethernet slot on the control system in SIMPL Windows, without a DM
switcher.
The IP ID is set within the DM-TX-200-2G’s and DM-TX-400-3G’s IP table using
Crestron Toolbox. For information on setting an IP table, refer to the Crestron
Toolbox help file. The IP IDs of multiple DM-TX-200-2G and DM-TX-400-3G
devices in the same system must be unique.
When setting the IP ID, consider the following:
•The IP ID of each unit must match an IP ID specified in the SIMPL
Windows program.
•Each device using IP to communicate with a control system must have a
unique IP ID.
