The DM-EXT-1021 KIT provides a cost-effective multimedia presentation solution for classrooms and meeting spaces. Consisting of a transmitter (HD-TXC-4KZ-101) and 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).
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.
