Product Overview
The Crestron DM-EXT-1021-1G-W KIT is a 4K 2x1 DM Essentials scaling auto-switcher and wall plate extender that distributes HDMI video over a single CATx cable for classrooms and meeting spaces. The kit pairs a white single-gang wall plate transmitter with a surface-mountable scaling receiver, extending video, audio, and power over CAT5e or higher cable. The receiver includes a 4K scaler and onboard control ports for direct display management. It is the white-finish version of the kit, matching light-colored wall plates and surrounds.
Product Description
The DM-EXT-1021-1G-W KIT consists of an HD-TXC-4KZ-101-1G-W white wall plate transmitter and an HD-RX-4K-210-C-E surface-mountable receiver, providing a cost-effective multimedia presentation solution. The transmitter accepts one HDMI input at a 1-gang wall plate location, while the receiver adds a second HDMI input for a local source or an optional media presentation wall plate, yielding 2x1 auto-switching. Power is transmitted over the CATx cable from the receiver to the transmitter, so only the receiver power pack is required. For resolutions up to 2K the maximum transmission distance is 230 ft (70 m), and for higher resolutions up to 4K it is 130 ft (40 m). The receiver provides a single HDMI output with a built-in 4K scaler that matches the native resolution of the connected display, supporting input resolutions up to 4K60 4:2:0. Audio de-embedding feeds a stereo analog line-level output to amplified speakers or a sound bar. Onboard COM (RS-232), IR, relay, and Versiport I/O ports plus CEC over HDMI enable display and equipment control with or without a control system. The kit supports EDID and HDCP 2.2 management, a built-in web interface, .AV Framework technology, XiO Cloud service, and native integration with Cisco Webex and Touch 10 devices. A black-finish version is also available, the DM-EXT-1021-1G-B KIT. For specifications not listed here, refer to the Crestron data sheet.
