USB-C AV + USB + GE 60W-charge 40m PoE-acc Tx

The Kramer EXT3-C-XR-T is an extended-reach HDBaseT 3.0 transmitter built around a USB-C source connection. It converts incoming signals into an HDBaseT 3.0 transmission for transport over twisted-pair CAT copper cable. The signal set includes 4K60Hz 4:4:4 HDMI video, USB, 1Gbps Ethernet, RS-232, and IR. Video can be extended up to 100m (330ft), while HDR10 support preserves compatibility with HDR content.

Ideal Use Cases

This transmitter is suited to systems that need to place a USB-C source away from the display or receiving equipment while maintaining high-resolution video and supporting data and control connections. It is particularly relevant when several signal types need to share structured CAT copper cabling instead of relying on separate long-distance runs.

• Extending a USB-C source to a remote 4K display location.
• Transporting video, USB, Ethernet, RS-232, and IR within an integrated AV system.
• Using existing or planned CAT copper cabling for an extended-reach video link.
• Supporting installations that require 4K60Hz 4:4:4 video and HDR10.

Why Choose This Model

The EXT3-C-XR-T combines a modern USB-C input with the signal capacity of HDBaseT 3.0. Its ability to carry HDMI video alongside USB, Ethernet, serial control, and IR makes it a focused option for installations where the source connection must support more than video alone. The supplied product data also specifies 60W USB-C charging, adding power delivery to the source-side workflow. Gigabit Ethernet bandwidth is listed at 1Gbps, supporting network transport as part of the extended signal set.

The transmitter converts its incoming signals into the transmitted HDBaseT 3.0 signal. This consolidated approach simplifies the long-distance portion of an installation while retaining separate AV, data, and control functions at the system level.

Installation and Integration

Connect the source through the transmitter’s USB-C input, then use twisted-pair CAT copper cable for the HDBaseT 3.0 link. The maximum stated video extension distance is 100m (330ft) at up to 4K@60Hz with 4:4:4 color sampling. Cable selection and the receiving side of the HDBaseT link should be planned for the required distance and signal configuration.

USB, Ethernet, RS-232, and IR transport allow the unit to fit into systems that include peripherals, network connectivity, serially controlled equipment, or infrared control. Because the available data does not specify included accessories, cables and receiving equipment should be selected separately according to the installation design.

Performance Highlights

The headline video capability is 4K at 60Hz with full 4:4:4 color sampling. This preserves detailed color information in content such as computer interfaces, fine graphics, and high-resolution video. HDR10 support expands compatibility with HDR sources and displays. The extended-reach design carries video as far as 100m (330ft) over CAT copper cable.

• Maximum stated video format: 4K@60Hz 4:4:4.
• Maximum stated video distance: 100m (330ft).
• Network bandwidth: 1Gbps.
• HDR format support: HDR10.
• Transmission platform: extended-reach HDBaseT 3.0.

What Makes It Different

The EXT3-C-XR-T is not limited to basic point-to-point video extension. Its USB-C input feeds a multi-signal HDBaseT 3.0 transport that includes HDMI video, USB, Gigabit Ethernet, RS-232, and IR. That combination addresses source connectivity, peripheral data, networking, and control within one transmitter platform. The 60W charging specification further distinguishes the USB-C connection by incorporating charging capability alongside signal input.

The pairing of 4K60Hz 4:4:4 performance with a stated 100m video reach is another defining characteristic. It provides extended distance without reducing the listed maximum video format to a lower chroma-sampling mode.

Final Assessment

The Kramer EXT3-C-XR-T is a purpose-built transmitter for extended USB-C AV installations that require more than video transport. Its HDBaseT 3.0 architecture combines 4K60Hz 4:4:4 video, HDR10, USB, 1Gbps Ethernet, RS-232, and IR, with video extension up to 100m over CAT copper cable. For systems centered on a USB-C source and a remote AV endpoint, it offers a concentrated set of signal, control, networking, and charging capabilities.
