EXT3−C−XR−T is a high−performance, extended−reach HDBaseT 3.0 transmitter, with a USB−C input, for 4K60Hz (4:4:4) HDMI, USB, Ethernet, RS−232, and IR signals over twisted pair. The EXT3−C−XR−T transmitter converts all input signals into the transmitted HDBaseT 3.0 signal. It extends video signals up to 100m (330ft) over CAT copper cables at up to 4K@60Hz (4:4:4) video resolution.

High Performance Standard Extender

Professional HDBaseT extender for providing extended–reach signals over twisted–pair copper infrastructures. EXT3–C–XR–T is a standard extender that can be connected to any market–available HDBaseT–compliant extension product. For optimum extension reach and performance, use recommended Kramer cables.

BYOD Ease and Convenience

Connect any DP–Alt–Mode–capable USB–C device as an AV presentation source, while providing the connected device with USB 2.0 and Ethernet connection, and (if PD–2.0–capable) up to 60 watts of power, via a single USB–C cable connection only.

Convenient Display Power On/Off Control

Simply press the DISPLAY ON button to toggle on and off the power of the remote CEC–enabled display; the button LED indicates the power on/off status of the remote display.

HDMI Signal Extension

Uncompressed 4K@60Hz (4:4:4) HDMI, HDCP 2.3, EDID, and CEC signals are passed through from the source to the display.

HDMI Support

Supports HDR10, deep color, x.v.Color, HDMI uncompressed audio channels, Dolby TrueHD, DTS–HD, 2K, 4K, and 3D as specified in HDMI 2.0.

HDMI Mirroring

The transmitter mirrors the input HDMI signal to the loop output port for connecting a local monitor or adding an additional unit in a daisy chain.

Flexible USB 2.0 Extension

An active USB host is connected to the extender at either the transmitter or receiver side. USB 2.0 signals are extended between the extender transmitter and receiver sides, enabling connection of the active USB host to both local and remote USB devices, such as cameras and audio devices, or HID (Human Interface Devices) mouse or keyboard devices.

I–EDIDPro Kramer Intelligent EDID Processing

Intelligent EDID handling, processing, and pass–through algorithm that ensures Plug and Play operation for HDMI source and display systems.

Multi–channel Audio Transmission

Up to 32 channels of digital stereo uncompressed signals for supporting studio–grade surround sound.

Ethernet Extension

Ethernet interface data flows in both directions, allowing extension of up to 1 Gbps Ethernet connectivity for LAN communication and device control.

Bidirectional RS–232 Extension

Serial interface data flows in both directions, allowing data transmission and device control.

Bidirectional Infrared Extension

IR interface data flows in both directions, allowing remote control of peripheral devices located at either end of the extended line.

Cost–effective Maintenance

Status LED indicators for HDMI, Loop, HDBT, and USB active host ports facilitate easy local maintenance and troubleshooting.
