The DM-TX-201-C provides a simple interface for computers and highdefinition AV sources as part of a complete Crestron® DigitalMedia™
system. Its low-profile, surface-mountable design makes it ideal for
installation beneath a conference table, inside a lectern or equipment rack,
or at virtually any other location in a boardroom, classroom, auditorium, or
residence. It functions as a DM 8G+® transmitter and switcher, providing
HDMI®, VGA, and analog audio inputs along with Ethernet and USB HID
ports for a total connectivity solution. In addition to DM 8G+, it is also
compatible with HDBaseT®, allowing it to be connected directly to the
input of an HDBaseT certified display device. It connects to the head end
or display location using a single CAT type twisted pair 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. The latest generation of DM is called
DigitalMedia 8G™ (DM 8G®). Engineered for ultra high-bandwidth and
ultimate scalability, DM 8G provides a true one-wire lossless transport for
moving high-definition video, audio, Ethernet, and control signals over a
choice of twisted pair or fiber optic cable.
| 800.237.2041
DM 8G over twisted pair copper wire is called DigitalMedia 8G+ (DM 8G+).
DM 8G+ handles uncompressed Full HD 1080p video signals with support
for HDCP, as well as computer signals up to WUXGA. All signals are
transported over a single CAT type cable, supporting distances up to
330 feet (100 m) using Crestron DM 8G Cable or CAT5e.[1]
HDBaseT® Certified
Crestron DigitalMedia 8G+ technology is designed using HDBaseT
Alliance specifications, ensuring interoperability with other HDBaseT
certified products. Via its DM 8G+ output, the DM-TX-201-C can be
connected directly to an HDBaseT compliant device without requiring
a DM receiver.
Multimedia Computer/AV Interface
The DM-TX-201-C provides simple switching between two inputs. The
inputs can be configured to switch automatically or be controlled through
a Crestron control system. Inputs include:
•• HDMI — Provides a digital multimedia input for mobile devices,
computers, and AV sources with resolutions up to HD 1080p60 and
WUXGA. Also handles DVI and DisplayPort Multimode signals using an
appropriate adapter or interface cable[2].
•• RGB — This VGA type input handles analog RGB signals up to WUXGA
1920x1200 pixels, as well as analog video up to 1080p60[3]. A 1/8”
(3.5mm) stereo audio input is included to accommodate the analog
audio signal from an unbalanced line-level source or
headphone output.
Note: Audio breakaway capability enables the analog audio input to be
used with either video input.
A single CAT type cable connects the DM-TX-201-C to a DM switcher
or receiver, or to an HDBaseT device, transporting video, audio, control,
networking, and power signals all through one simple RJ45 connection.[1,4]
Used with a single DM 8G+ Receiver/Room Controller and optional
Crestron control system, the DM-TX-201-C affords a simple solution for
extending a computer or AV signal to a single display. As part of a larger
system using a DM-MD series switcher, multiple DM-TX-201-Cs may be
installed to enable the distribution of several sources at different locations
to feed multiple displays throughout any room or larger facility.
DM-TX-201-C DigitalMedia 8G+® Transmitter 201
controlling the connected source device right through the HDMI
connection, potentially eliminating the need for any dedicated control wires
or IR emitters.
Compact and Versatile
The DM-TX-201-C is designed to be mounted to a flat surface or placed on
a shelf. It is compact enough to fit discreetly inside a presentation lectern
or beneath a table, and can even be attached to a rack rail in the back
of an equipment cabinet. The unit can be powered using the wall mount
power pack (included), or via PoDM (Power over DigitalMedia) for a true
one-wire solution[4]. An array of indicators is provided for easy setup and
A Digital Upgrade for Legacy Systems
The DM-TX-201-C also affords a perfect signal converter for integrating
DigitalMedia with analog-based systems like Crestron MPS, QuickMedia®,
and the CEN-RGBHV Series. A simple HD15 VGA cable connected between
the output of an MPS system and the input of the DM-TX-201-C allows
every RGB, component, S-Video, and composite video input on the MPS to
be converted to DigitalMedia[3]. Analog audio is converted similarly through
an unbalanced stereo audio cable. The DM-TX-201-C’s HDMI input may
also be used to expand the input capabilities of the MPS system to handle
digital AV sources.
Please refer to the DigitalMedia Resources Webpage at for additional design tools and
reference documents.
DM-TX-201-C – Top, Front, and Bottom Views
In addition to its DM 8G+ output, there is also an HDMI output provided
to feed a local HDMI or DVI monitor, eliminating the need for an extra
outboard distribution amp or other hardware.
LAN Connectivity
Along with high-definition AV and control, DigitalMedia also integrates
high-speed Ethernet networking for a total signal distribution solution. The
DM-TX-201-C includes a 10/100 Ethernet port, providing a convenient LAN
connection for a local network device.
USB Signal Extension
The DM-TX-201-C also functions as a keyboard/mouse extender, allowing
the connected computer (or other USB HID-compliant host) to be controlled
by a mouse and/or keyboard located at a presentation lectern, conference
table, or some other remote location. Additional USB devices of virtually
any type can be supported using Crestron USB over Ethernet
Extenders (USB-EXT-DM)[5].
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-201-C provides a gateway for

1. For DM 8G+ or HDBaseT wiring, use Crestron DM-CBL-8G DigitalMedia 8G Cable or
third-party CAT5e (or better) UTP or STP. (Crestron legacy DM-CBL DigitalMedia Cable or
DM-CBL-D DigitalMedia D Cable may also be used.) The maximum wire length for DM 8G+
is 330 ft (100 m) between devices. Shielded cable and connectors are recommended to
safeguard against unpredictable environmental electrical noise which may impact performance
at resolutions above 1080p. Refer to the Crestron DigitalMedia Design Guide, Doc. #4546 for
complete system design guidelines. DM 8G+ is compatible with HDBaseT Alliance
specifications for connecting to HDBaseT compliant equipment. All wire and cables are
sold separately.
2. HDMI requires an appropriate adapter or interface cable to accommodate a DVI or DisplayPort
Multimode signal. CBL-HD-DVI interface cables are available separately.
3. The RGB/VGA input can actually accept component, composite, and S-Video signals through
an appropriate adapter (not included), or via direct interface to Crestron MPS Series products.
However, input sync detection is not provided for composite or S-Video signal types through
this connection.
4. Receiving Power over DM (PoDM) or Power over HDBaseT (PoH) requires connection to a
switcher or other equipment that has a PoDM or PoH PSE (Power Sourcing Equipment) port.
Any wiring that is connected to a PoDM or PoH PSE port is for intra-building use only and
should not be connected to a line that runs outside of the building in which the PSE is located.
5. USB-EXT-DM USB over Ethernet Extender Modules are sold separately. Refer to the
USB-EXT-DM spec sheet for more information.
6. References to the IEEE 802.3af and 802.3at standards are used to demonstrate that PoDM
and PoH technology is similar in function to PoE and follows the same essential specifications.
The DM-TX-201-C cannot be powered over Ethernet, and its DM OUT port should not be
connected directly to an Ethernet network or device.
