4K60 4:2:0 USB-C Transmitter over Long-Reach HDBT 1.0

The Kramer EXT3-UE-R is a comprehensive USB 2.0 and Ethernet PoC receiver designed for extended-reach transmission over twisted-pair CAT cable. Installed at the receiving end of the connection, it converts the transmitted CAT signal into USB 2.0, Ethernet, RS-232, and audio signals. Its two-way powering capability supports an installation centered on a single extended-reach CAT link and a clearly defined receiver endpoint.

Ideal Use Cases

The EXT3-UE-R is intended for systems that need multiple signal types available at a remote receiving location. A single receiver provides access to USB 2.0 for USB connectivity, Ethernet for network communication, RS-232 for serial communication or control, and audio. This combination is relevant when those services must travel across an extended-reach twisted-pair CAT connection instead of being handled as separate local signal paths.

• Remote USB 2.0 connectivity over a CAT-based extension system
• Installations requiring Ethernet at the receiving endpoint
• Systems using RS-232 communication or control
• Applications that also need an audio signal at the receiver
• Extended-reach links using twisted-pair CAT cabling

Why Choose This Model

This model combines four specified signal categories in one receiver: USB 2.0, Ethernet, RS-232, and audio. The source also identifies it as a PoC receiver with comprehensive two-way powering. These characteristics make the EXT3-UE-R a focused endpoint for installations built around the matching transmitted CAT signal. Its role is explicit: receive the CAT transmission and convert it back into the listed destination signals.

The exact EXT3-UE-R designation is important because the source identifies this SKU as the receiver model. It should be selected according to that endpoint role rather than treated as a transmitter or a general-purpose standalone converter.

Installation and Integration

The receiver is installed at the destination side of an extended-reach twisted-pair CAT connection. The incoming CAT signal is converted into USB 2.0, Ethernet, RS-232, and audio signals for connection to the appropriate receiving equipment. The available source data does not identify the required companion transmitter, connector counts, included cables, power supply, or configuration procedure, so those details should be confirmed for the complete system before installation.

The source data references BC-UNIKAT CAT6A U/FTP bulk cable in 100, 305, and 500-meter lengths and C-UNIKAT CAT6A U/FTP cable assemblies from 0.6 to 100 meters. These are listed cable products and their available lengths; the data does not state that every listed length represents the supported operating distance of the EXT3-UE-R. USB 2.0 A-to-A and A-to-B cable products in 3-to-15-foot lengths are also referenced, but no cable is identified as included with the receiver.

Performance Highlights

The documented performance centers on signal conversion and extension functionality. USB operation is specified as USB 2.0, while network connectivity is identified as Ethernet. RS-232 and audio are also recovered from the transmitted CAT signal. No Ethernet data rate, audio format, USB port count, latency figure, or maximum validated extension distance is provided in the source data.

No supported video resolution or color-sampling specification is documented for this SKU in the scraped product information. Accordingly, 4K60, 4:2:0, USB-C transmission, and HDBT 1.0 performance are not presented as verified capabilities of the EXT3-UE-R receiver.

What Makes It Different

The defining feature of the EXT3-UE-R is the specific mix of services recovered at one receiver endpoint. Instead of being described only as a USB extender, it converts the transmitted CAT signal into USB 2.0, Ethernet, serial RS-232, and audio. Its two-way powering design is another stated characteristic, while the PoC receiver designation distinguishes its function within the extension path.

This focused specification also makes system matching especially important. The product data describes a receiver, so the transmitter side and the selected CAT cabling must be planned as parts of the complete connection.

Final Assessment

The Kramer EXT3-UE-R is a purpose-defined receiver for an extended-reach twisted-pair CAT extension system. It is a strong fit when the receiving location specifically requires USB 2.0, Ethernet, RS-232, and audio from the transmitted CAT signal, together with the model’s stated two-way powering capability. Buyers should verify the companion transmitter, required cabling, connector configuration, operating distance, included accessories, and power arrangements because those details are not supplied in the available product data.
