The DM‑EXT‑1021‑1G KIT provides a cost-effective multimedia presentation solution for classrooms and meeting spaces. Consisting of a wall plate transmitter (HD‑TXC‑4KZ‑101‑1G[-W/B]) and surface-mountable receiver (HD‑RX‑4K‑210‑C‑E), the kit extends an HDMI® signal over a CATx (CAT5e or higher) twisted pair cable. For resolutions up to 2K, the maximum transmission distance is 230 ft (70 m). For higher resolutions up to 4K, the maximum transmission distance is 130 ft (40 m).1

NOTE: Power is transmitted over the CATx cable that connects the transmitter to the receiver. The transmitter provides one HDMI input. The receiver provides an additional HDMI input that can be connected to a local AV source or to an optional Crestron media presentation wall plate (MP‑WP152, sold separately).

The DM‑EXT‑1021‑1G KIT is available in two models, the DM‑EXT‑1021‑1G‑B KIT and DM‑EXT‑1021‑1G‑W KIT. The DM‑EXT‑1021‑1G‑B KIT includes a HD‑TXC‑4KZ‑101‑1G‑B black wall plate transmitter, and the DM‑EXT‑1021‑1G‑W‑KIT includes a HD‑TXC‑4KZ‑101‑1G‑W white wall plate transmitter.

Automatic Input Switching
Automatic switching between the DM input and HDMI input on the receiver occurs based on the last connected input or on an assigned routing priority. Switching behavior is configurable using the web interface or programmable using a Crestron control system. In addition to automatic switching, input selection push buttons on the receiver enable the desired input to be selected manually.

HDMI Output with 4K Scaler
A single HDMI output with a built-in scaler connects the receiver to a display or other device with an HDMI input. Input resolutions are automatically scaled to match the native resolution of the display device, resulting in optimal image quality. For applications requiring comprehensive EDID management, the web interface is used to ensure that every input is displayed at its optimal resolution and format. Input resolutions up to 4K60 4:2:0 are supported.

Audio De-embedding
The analog audio output on the receiver extracts the stereo audio signal from digital sources to feed a sound bar, amplified speakers, or a separate sound system. The analog audio output is active only when the input is receiving a two‑channel stereo signal.

Device Control
Equipped with onboard control ports, the receiver can control various devices in a room. The COM (RS-232) port and CEC over the HDMI output enable the display device to be turned on or off automatically without the use of a control system. With the use of a control system, the IR port can also control the display device. Two relay ports are provided for controlling a projection screen and other low-voltage contact closure activated equipment. Two Versiport I/O ports enable the integration of devices such as power sensors and motion detectors. An Ethernet port connection to a LAN also provides control by enabling use of the built-in web interface as well as connection to a control system.

NOTE: The COM, IR, and Ethernet ports cannot be used to extend signals over the CATx cable connection between the receiver and the transmitter.

USB Power Port
A USB power port is included on the transmitter to power USB devices (500mA maximum).

NOTE: No USB data is passed through the USB power port. The port cannot be used to extend USB data, video, or audio signals.

.AV Framework™ Technology Support
In addition to a built-in web interface and control system programming, the built-in .AV Framework technology of the MPC3‑201 and MPC3‑302 control systems will control the HD‑RX‑4K‑210‑C‑E as a switcher. (For information about .AV Framework technology, visit www.crestron.com/avframework.)

XiO Cloud® Service Support
The DM-EXT-1021 is compatible with the XiO Cloud service, which is an Internet of Things (IoT) platform for remotely provisioning, monitoring, and managing Crestron devices across an enterprise or an entire client base. Built on the Microsoft® Azure® software platform and using industry-leading Azure IoT Hub technology, the XiO Cloud service enables installers and IT managers to easily deploy and manage thousands of devices. Unlike other virtual machine based cloud solutions, Azure services provide unlimited scalability to suit the ever growing needs of an enterprise. For more information, visit www.crestron.com/xiocloud.

Native Integration with Cisco® Webex® and Touch 10 Devices
Native integration of the Cisco API enables source inputs of the HD‑RX‑4K‑210‑C‑E receiver to be added to a compatible Cisco Webex video conference system that is controlled by a Cisco Touch 10 control unit. Eliminating the need for control system programming, integration with Cisco® devices is accomplished by using the Crestron Configuration tool, which is hosted on the Crestron website at configuration.crestron.com.

Notes:

  1. For the DM CATx cable connection, use Crestron DM-CBL-8G, Crestron DM-CBL-ULTRA, or third-party CAT5e or higher cable. To safeguard against unpredictable environmental electrical noise that may impact performance at resolutions above 1080p, shielded cable and connectors are recommended for all applications and are required when bundling multiple cables in a wire run. Wire and cables are sold separately. The DM ports in this kit are not compatible with DigitalMedia 8G+®, HDBaseT®, PoE, or PoDM technology or any other type of CATx based interface or network.
  2. The HDMI input requires an appropriate adapter or interface cable to accommodate a DVI or Dual-Mode DisplayPort signal. CBL‑HDI‑DVI interface cables are available separately.
  3. The HDMI output requires an appropriate adapter or interface cable to accommodate a DVI signal. CBL‑HDI‑DVI interface cables are available separately.
