HD-TX-4KZ-421-CHGR

The HD-TX-4KZ-421-CHGR is a DM® Essentials 4K60 4:4:4 transmitter designed to interoperate with a DM® Essentials receiver or DMPS Essentials 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 (Crestron DM CBL 8G or DM CBL ULTRA sold separately) is needed to connect the HD-TX-4KZ-421-CHGR to the DM Essentials receiver or DMPS Essentials 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 Essentials Receiver or DMPS Essentials Switcher

The DM Essentials output port of the HD-TX-4KZ-421-CHGR must be connected to a DM Essentials input port of a DM Essentials receiver or DMPS Essentials switcher. Examples of supported DM Essentials 4K60 4:4:4 receivers are the HD‑RXC‑4KZ‑101 and HD‑RXCA‑4KZ‑101. Supported DMPS Essentials switchers are the HD‑PS622, HD‑PS621, HD‑PS402, HD‑PS401, and HD‑RX‑4K‑210‑C‑E.

The HD-TX-4KZ-421-CHGR can be configured and controlled only when it is used with a DMPS Essentials 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 Essentials switcher, the web interface of the switcher or control system programming hosted by the switcher can be used to configure AV switching behavior. Switching among the HDMI and USB-C DisplayPort inputs occurs 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 Essentials receiver or DMPS Essentials 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 Essentials receiver or DMPS Essentials switcher.3

1. For DM Essentials 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 Essentials transmitter is paired with a surface-mountable DM Essentials 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 Essentials transmitter is paired with a wall plate DM Essentials receiver, the power pack included with the transmitter is used to power both devices. When a DM Essentials transmitter is paired with a DMPS Essentials switcher, the switcher provides power to the DM Essentials transmitter. The DM Essentials transmitter must be connected to the included power pack only when charging capability is to be provided by a USB-C input.

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 Essentials receiver or DMPS Essentials 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.
