Product information

Description

The Kramer EXT3-TR is a high-performance HDBaseT 3.0 AV transceiver that extends 4K@60Hz (4:4:4) HDMI, USB 2.0, RS-232, and IR signals over twisted-pair copper cable. The unit can be configured as either the transmitter or the receiver: in transmitter mode it converts input signals to an HDBaseT 3.0 stream, and in receiver mode it restores the HDBaseT stream back to the original HDMI, USB, RS-232 and IR interfaces. It supports video extension up to 40 m (130 ft) over CAT copper cables at up to 4K@60Hz (4:4:4) and is designed for professional AV installations requiring long-reach signal distribution.

Advantages

EXT3-TR provides a single-cable extension solution for high-resolution HDMI video, multichannel audio, USB peripherals, and control interfaces, reducing cabling complexity. It supports HDMI 2.0 feature set including HDCP 2.3, EDID and CEC passthrough, HDR10 and deep color, and delivers up to 32 channels of uncompressed digital audio. The device offers HDMI mirroring via a loop output for local monitoring, flexible USB 2.0 host placement for remote cameras or HID devices, bidirectional RS-232 and IR for control, and status LEDs for simplified troubleshooting. Its fan-less MegaTOOLS enclosure allows dropped-ceiling or rack-side-by-side installation for neat, low-noise deployments.

Suitable for

  • Professional AV distribution in conference rooms, auditoriums, and lecture halls
  • Digital signage and public displays requiring long-reach 4K video
  • Remote camera, audio, or USB HID device extension for streaming or control
  • Integrator setups that need RS-232 and IR control over distance

Когда может не подойти

EXT3-TR is not intended for wireless extension — it requires high-quality twisted-pair copper (CAT) cabling and performs to specified reach only when recommended cables and installation practices are used. For runs significantly longer than the specified distance or environments without reliable copper infrastructure, a different optical-fiber solution may be more appropriate.

Key specifications

  • Video support: up to 4K@60Hz (4:4:4), HDMI 2.0 feature set, HDR10, deep color, 3D
  • Audio: up to 32 channels of uncompressed digital audio, Dolby TrueHD and DTS-HD pass-through
  • Extension technology: HDBaseT 3.0 over twisted-pair copper
  • Maximum copper extension (typical): up to 40 m (130 ft) at 4K@60Hz (4:4:4)
  • USB: USB 2.0 extension with host connection at either transmitter or receiver side
  • Control interfaces: bidirectional RS-232 and bidirectional IR
  • Local HDMI loop output for mirroring
  • Power: 12 VDC, 2 A
  • Enclosure: fan-less MegaTOOLS for dropped-ceiling or side-by-side 1U rack mounting
  • Dimensions: 190 mm x 116 mm x 27 mm

How to use

Install the unit as either the transmitter or receiver according to the installation plan. Connect the HDMI source and any local USB devices to the transmitter-side ports, or connect the HDMI display and remote USB devices to the receiver-side ports depending on configuration. Use high-quality CAT copper cable between transmitter and receiver and power each unit with the specified 12 VDC supply. Use the loop HDMI output on the transmitter for a local monitor if required. Configure EDID, HDCP and audio settings from the source or connected devices as needed and use the status LEDs to verify link and host activity during setup.

What to consider before purchase

  • Required maximum cable length and whether copper CAT cabling meets site needs
  • Compatibility with source and display HDMI features (HDCP, HDR, EDID handling)
  • Need for USB 2.0 extension and which end (transmitter or receiver) will host the active USB device
  • Control requirements for RS-232 and IR over distance
  • Rack or ceiling mounting method and available space for the MegaTOOLS enclosure

Usage recommendations

For reliable 4K@60Hz (4:4:4) performance use recommended Kramer copper cables, keep cable runs within specified distances, and mount the units in ventilated locations using the MegaTOOLS options. Verify EDID and HDCP settings between source and display during commissioning and use the local HDMI loop for onsite monitoring or daisy-chaining additional units.
