The DM‑TX‑4K‑302‑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 HDMI®, VGA, and analog audio inputs and as a control module, providing RS-232 and IR control ports, plus Ethernet and USB HID ports for a total connectivity solution.

Its low-profile, surface-mountable design makes the DM‑TX‑4K‑302‑C 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 connects to the head end or display location using a single CAT type twisted pair cable. In addition to DM 8G+, it is also compatible with HDBaseT® standard, which allows it to be connected directly to the input of an HDBaseT certified display device.¹

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‑302‑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 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® products is called DigitalMedia 8G™. Engineered for ultra-high bandwidth and ultimate scalability, DM 8G® products provide 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, Dolby Atmos®, and DTS HD®, 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 ft (100 m) using Crestron DM Ultra Cable, Crestron DM 8G Cable, or third-party CAT5e. Higher resolutions up to UHD and 4K are supported at distances up to 330 ft (100 m) using DM Ultra Cable, 230 ft (70 m) using DM 8G Cable, or 165 ft (50 m) usingCAT5e.¹

HDBaseT® Compatible
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‑302‑C can be connected directly to an HDBaseT compliant device without requiring a DM receiver.

Multimedia Computer/AV Interface
The DM‑TX‑4K‑302‑C provides simple switching among three inputs. The inputs can be configured to switch automatically or be controlled through a Crestron control system. Auto-detection on each input enables plug-andplay simplicity, supporting a wide range of input types without requiring any special configuration. Inputs include:

• HDMI — Provides two independent digital multimedia inputs for mobile devices, computers, and AV sources with resolutions up to UHD and DCI 4K. These inputs can also handle DVI and Dual-Mode DisplayPort™ signals using an appropriate adapter or interface cable.
• VGA — This input handles analog VGA and RGB signals up to WUXGA 1920x1200 pixels. It can also handle component, S-Video, and composite video signals up to 1080p60 through an appropriate adapter or breakout cable. A 1/8 in.(3.5 mm) stereo audio input is included to accommodate the analogaudio signal from an unbalanced line-level source or headphone output.

Note: Analog audio breakaway capability enables the analog audio input to be used with any video input.

A single CAT type cable connects the DM‑TX‑4K‑302‑C to a DM switcher or receiver, or to an HDBaseT device, transporting video, audio, control, networking, and power signals all through one simple R-J45 connection.^1,2,3 Used with a single DM 8G+ Receiver/Room Controller and optional Crestron control system, the DM‑TX‑4K‑302‑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‑302‑Cs may be deployed to enable the distribution of several sources at different locations to feed multiple displays throughout any room or larger facility.

Local HDMI Output
An HDMI output is included to enable pass-through of the selected video and audio signals 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‑302‑C includes a 10/100 Ethernet port, which can be used to provide a convenient LAN connection for a local network device.

USB Signal Extension
The DM‑TX‑4K‑302‑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‑302‑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‑LOCAL and USB‑EXT‑DM‑REMOTE) and Crestron USB over Ethernet Network Wall Plate Endpoints (USB‑NX2‑LOCAL‑1G and USB‑NX2‑REMOTE‑1G).^4,5

Embedded Device Control
The DM‑TX‑4K‑302‑C includes built-in IR, RS-232, and Ethernet control ports to enable programmable control of the devices connected to it (via a control system). 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‑302‑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.

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‑302‑C. The cable caddy gets its power and control from the DM‑TX‑4K‑302‑C through a simple USB connection.⁴

Compact and Versatile
The DM‑TX‑4K‑302‑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. It can be powered using the optional power pack, PW‑2407WU (sold separately), or PoDM+ (Power over DigitalMedia Plus) for a true one-wire solution.^2,3,4 An array of indicators is provided for easy setup and troubleshooting.
