        The HD-TX-4KZ-421-CHGR is a DM Lite® 4K60 4:4:4 transmitter designed to interoperate with a DM Lite® receiver or DMPS Lite™ switcher. The HDMI® inputs of the HD-TX-4KZ-421-CHGR enable the transmission of an HDMI signal. The USB-C® inputs with DisplayPort™ Alt Mode capability enable the transmission of a DisplayPort AV signal. A CAT5e or higher twisted pair cable is used to connect the HD-TX-4KZ-421-CHGR to the DM Lite receiver or DMPS Lite switcher. For 1080p, WUXGA, and 2K signals, a cable length of up to 230 ft (70 m) is supported. For UHD and 4K signals, a cable length of up to 130 ft (40 m) is supported.1

        Interoperability with a DM Lite Receiver or DMPS Lite Switcher
        The DM Lite output port of the HD-TX-4KZ-421-CHGR must be connected to a DM Lite input port of a DM Lite receiver or DMPS Lite switcher. Examples of supported DM Lite 4K60 4:4:4 receivers are the HD‑RX‑4KZ‑101, HD‑RXA‑4KZ‑101, HD‑RXC‑4KZ‑101, and HD‑RXCA‑4KZ‑101. Supported DM Lite 4K60 4:2:0 receivers are the HD‑RX‑101‑C‑E, HD‑RXC‑101‑C‑E, HD‑RX‑201‑C‑E, HD‑RX‑101‑C‑1G‑E, and HD‑RXC‑101‑C‑1G‑E. Supported DMPS Lite switchers are the HD‑PS622, HD‑PS621, HD‑PS402, HD‑PS401, and HD‑RX‑4K‑210‑C‑E(‑POE).

        The HD-TX-4KZ-421-CHGR can be configured and controlled only when it is used with a DMPS Lite switcher. The web interface of the switcher can be used to configure the HD-TX-4KZ-421-CHGR. In addition, control system programming and .AV Framework™ software support of the HD-TX-4KZ-421-CHGR is hosted by the switcher.

        4K60 4:4:4 and HDR Support
        The HD-TX-4KZ-421-CHGR supports video resolutions up to 4K60 with 4:4:4 color sampling. HDR10, HDR10+, and Dolby Vision® video formats are also supported.2

        Automatic Switching of Inputs
        When the HD-TX-4KZ-421-CHGR is used with a DMPS Lite switcher, the web interface of the switcher or control system programming hosted by the switcher can be used to configure the AV switching behavior of the HD-TX-4KZ-421-CHGR. Switching among the HDMI and USB-C DisplayPort inputs can occur based on the last connected input or on the routing priority assigned to each input. In addition, input selection push buttons on the front panel of the HD-TX-4KZ-421-CHGR enable the desired input to be selected manually.

        USB-C DisplayPort Inputs with Charging Capability
        When the HD-TX-4KZ-421-CHGR is powered by the included power pack, each USB-C DisplayPort input can charge the connected AV source (for example, a laptop) with up to 60W of power. If the HD-TX-4KZ-421-CHGR is powered by a remote DM Lite receiver or DMPS Lite switcher, no charging capability is provided by the USB-C inputs.

        Compact, Surface‑Mountable Design
        Compact in design, the HD-TX-4KZ-421-CHGR can be mounted onto a flat surface such as the underside of a table, behind a credenza, or inside a podium. It can also be attached to a single rack rail in the back of an equipment cabinet. The HD-TX-4KZ-421-CHGR can receive power from the included power pack or from the remote DM Lite receiver or DMPS Lite switcher.3

        1. For DM Lite connections, 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. Cables are sold separately.
        2. For HDMI inputs, 4K60 4:4:4 performance and HDR support require the use of HDMI cables and couplers with a minimum TMDS bandwidth of 18 Gbps. If 4K60 4:2:0 or 4K30 4:4:4 performance is acceptable, cables and couplers with a minimum bandwidth of 10.2 Gbps may be used. Bandwidth loss is cumulative; therefore, performance may be reduced when inserting multiple cables and couplers inline.

          For USB-C DisplayPort inputs, 4K60 4:4:4 performance and HDR support require the use of USB 3.2 Gen 1 (5 Gbps) cables with support for DisplayPort Alt Mode (DisplayPort 1.4 video, 4K60 4:4:4, 2 lanes). Cables are sold separately.
        3. When a surface-mountable DM Lite transmitter is paired with a surface-mountable DM Lite receiver, either the power pack included with the transmitter or the receiver can be used to power both devices. A power pack must not be connected to both devices simultaneously.

          When a surface-mountable DM Lite transmitter is paired with a wall plate DM Lite receiver, the power pack included with the transmitter is used to power both devices.

          When a DM Lite transmitter is paired with a DMPS Lite switcher, the switcher provides power to the DM Lite transmitter. The DM Lite transmitter must not be connected to the included power pack.
        4. The HDMI input requires an appropriate adapter or interface cable to accommodate a Dual-Mode DisplayPort or DVI signal. CBL-HD-DVI interface cables are sold separately.
        5. In order for a USB-C DisplayPort input to charge the connected AV source, the HD‑TX‑4KZ‑421-CHGR must be powered by the included power pack. If the HD-TX-4KZ-421-CHGR is powered by a remote DM Lite receiver or DMPS Lite switcher, no charging capability is provided by a USB-C input.

          CBL-USB3G1-C-C-6 and CBL-USB3G2-C-C-3 cables are sold separately.
        6. Examples of supported DM Lite 4K60 4:4:4 receivers are the HD‑RX‑4KZ‑101, HD‑RXA‑4KZ‑101, HD‑RXC‑4KZ‑101, and HD‑RXCA‑4KZ‑101. Supported DM Lite 4K60 4:2:0 receivers are the HD‑RX‑101‑C‑E, HD‑RXC‑101‑C‑E, HD‑RX‑201‑C‑E, HD‑RX‑101‑C‑1G‑E, and HD‑RXC‑101‑C‑1G‑E. Supported DMPS Lite switchers are the HD‑PS622, HD‑PS621, HD‑PS402, HD‑PS401, and HD‑RX‑4K‑210‑C‑E(‑POE).
