The DM-TX-4K-202-C provides a versatile interface for computers and
high-definition AV sources as part of a complete Crestron® DigitalMedia™
system. It functions as a DM 8G+® transmitter and switcher with two
HDMI® inputs. It also functions as a control module, providing RS-232 and
IR control ports, plus Ethernet and USB HID ports for a total connectivity
solution. It connects to the head end or display location using a single CAT
type twisted pair cable.[1] 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. 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.

4K Ultra HD
Crestron DigitalMedia continues to advance the standard for digital AV
signal distribution, delivering the world’s first end-to-end 4K system solution.
The DM-TX-4K-202-C features the latest DM 8G+ technology, providing
support for the transport of 4K and Ultra HD video signals. Support for 4K
video also ensures support for the latest generation of computers and
monitors with native resolutions beyond 1080p and WUXGA.
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, and control signals over a choice of
twisted-pair or fiber optic cable.
DM 8G over twisted-pair copper wire is called DigitalMedia 8G+ (DM 8G+).
DM 8G+ handles uncompressed Full HD 1080p, Ultra HD, 2K, and 4K video
signals with support for 3D, Deep Color, and HDCP 2.2. 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 a single CAT type wire, supporting 1080p, WUXGA,
and 2K signals at distances up to 330 feet (100 m) using Crestron DM Ultra
or DM 8G Cable, or third-party CAT5e. Higher resolutions up to UHD and 4K
are supported at distances up to 330 feet (100 m) using DM Ultra Cable,
230 feet (70 m) using DM 8G Cable, or 165 feet (50 m) using 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-4K-202-C can be connected
directly to an HDBaseT compliant device without requiring a DM receiver.
DM-TX-4K-202-C 4K DigitalMedia 8G+® Transmitter 202
Multimedia Computer/AV Interface
The DM-TX-4K-202-C provides two independent 4K HDMI inputs to
accommodate connections from mobile devices, computers, and AV
sources with resolutions up to UHD and 4K DCI. These inputs can also
handle DVI and Dual-Mode DisplayPort signals using an appropriate
adapter or interface cable. Switching between the two inputs can be
configured to switch automatically or be controlled through a Crestron
control system.
A single CAT type cable connects the DM-TX-4K-202-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.[1,2]
Used with a single DM 8G+ Receiver/Room Controller and optional Crestron
control system, the DM-TX-4K-202-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-4K-202-Cs may be
deployed to enable the distribution of several sources at different
locations to feed multiple displays throughout any room or
larger facility.
Crestron Connect It™
A Crestron Connect It Cable Caddy (TT-100 series) offers a convenient
tabletop connectivity solution that works seamlessly with the
DM-TX-4K-202-C. The cable caddy gets its power and control from the
DM-TX-4K-202-C through a simple USB connection.
Compact and Versatile
The DM-TX-4K-202-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.[2] An array of indicators is provided on the unit for
easy setup and troubleshooting.
Local HDMI Output
An HDMI output is included to enable pass-through of the
selected source to feed a local display, monitor, or 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-TX-4K-202-C includes a 10/100
Ethernet port, providing a convenient LAN connection for a local
network device.
Embedded Device Control
The DM-TX-4K-202-C includes built-in IR, RS-232, and Ethernet
control ports to enable programmable control of the devices
connected to it. It also offers 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-TX-4K-202-C provides a gateway for
controlling the connected source devices right through their HDMI
connections, potentially eliminating the need for any dedicated
control wires or IR emitters.
USB Signal Extension
The DM-TX-4K-202-C functions as a versatile USB keyboard/
mouse extender with both host and device ports provided
onboard. This allows a computer (or other USB HID-compliant
host) to be connected to the DM-TX-4K-202-C and controlled
remotely by a USB HID keyboard and/or mouse located elsewhere.
Alternately, the keyboard/mouse may be connected locally and
used to control a remote computer. Routing of the USB HID
signals is handled through the DigitalMedia system. Support for
other types of USB devices can be enabled using Crestron USB
over Ethernet Extenders (USB-EXT-DM)[3].

1. The maximum cable length for DigitalMedia 8G+ (DM 8G+) or HDBaseT is dependent upon
the type of cable and resolution of the video signal. Refer to the “Maximum Cable Lengths”
table for a detailed overview. Crestron legacy cable models DM-CBL DigitalMedia Cable and
DM-CBL-D DigitalMedia D Cable support the same resolutions and cable lengths as CAT5e.
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. 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.
3. USB-EXT-DM USB over Ethernet Extender Modules are sold separately. Refer to the
USB-EXT-DM spec sheet for more information.
4. HDMI requires an appropriate adapter or interface cable to accommodate a DVI or Dual-Mode
DisplayPort signal. CBL-HD-DVI interface cables are available separately.
5. Crestron Connect It Cable Caddy (TT-100 series) sold separately. Refer to the TT-100 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-4K-202-C cannot be powered over Ethernet, and its DM OUT port should not be
connected directly to an Ethernet network or device.
