The Crestron ® HD-MD-4K-400 provides a cost-effective multimedia presentation solution for classrooms and meeting spaces. Consisting of a transmitter (HD-TX-301-C-E) and receiver (HD-RX-4K-210-C-E), the HD-MD-4K-400 extends an HDMI® or VGA 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 two HDMI inputs and one VGA input with a complementary stereo analog audio 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).
Automatic Switching of Inputs
Automatic switching among the HDMI and VGA inputs on the transmitter and the HDMI input on the receiver can occur based on the last connected input or on the routing priority assigned to each input. 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 transmitter and receiver enable the desired input to be selected manually.
NOTE: The analog audio input on the transmitter is switched in tandem with the VGA input and cannot be paired with an HDMI input. The analog audio input can also be used with an audio-only source with no video source connected.
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 can be used to ensure that every input is displayed at its optimal resolution and format. Input resolutions up to 4K60 4:2:0 are supported.
The analog audio output on the receiver enables the HD-MD-4K-400 to extract 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 2-channel stereo signal from the analog input or an HDMI input.
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 can 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.
.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 can be used to 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 HD-MD-4K-400 is compatible with the XiO Cloud service, which is an IoT (Internet of Things) 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 deploy and manage thousands of devices in the amount of time it previously took to manage a single device. Unlike other virtual machine-based cloud solutions, Azure services provide unlimited scalability to suit the ever-growing needs of an enterprise.

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 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. Configuration includes the selection of the desired Crestron and Cisco hardware models and the assignment of HD-RX-4K-210-C-E input names and icons for use on the Cisco Touch 10 screen. The resulting configuration file is then downloaded from the website and loaded to the HD-RX-4K-210-C-E using the HD-RX-4K-210-C-E web interface. Communication is established between the HD-RX-4K-210-C-E and Cisco devices, enabling the Cisco Touch 10 to display and control the additional HD-RX-4K-210-C-E inputs.
The transmitter and receiver can be placed on or attached to a flat surface. The transmitter can fit discreetly inside a presentation lectern or be attached to the underside of a table. The receiver can be mounted onto a wall behind a display or onto a ceiling above a projector. The devices can also be attached to a rack rail of an equipment cabinet.

- For the DM Lite 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. DM Lite ports are not compatible with DigitalMedia 8G+®, HDBaseT®, PoE, or PoDM technology or any other type of CATx based interface or network.
- 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.
- The VGA input requires an appropriate breakout cable or adapter to accommodate an RGB or component video signal.
