Repeater AV ATEN True 4K HDMI / USB HDBaseT 3.0 transceptor 4096 x 2160

The ATEN VE1843 is a True 4K HDMI/USB HDBaseT 3.0 transceiver that combines transmitter and receiver functions in a single unit. Designed for long-distance, high-quality AV signal transmission, it supports uncompressed True 4K (4096 x 2160) at 60 Hz 4:4:4 with HDR over a single Cat 6A cable up to 100 m (328 ft). The device carries video, audio, IR, RS-232, Gigabit Ethernet and USB 2.0 signals and features HDMI audio embedding and de-embedding. Its fanless fin heat-sink enclosure and durable hardware are intended for continuous operation in environments such as conference rooms, auditoriums, banquet halls and museums.

Advantages

The VE1843 offers flexible deployment by allowing one unit to be configured as either a transmitter or a receiver, reducing inventory and simplifying system design. It delivers uncompressed True 4K HDMI with HDR at long distances with zero latency, preserves full audio/video fidelity and consolidates multiple signals over a single Cat 6A cable. The fanless fin heat-sink provides passive thermal dissipation for reliable non-stop operation, while user-focused features — including clear port labeling, built-in mounting brackets, front writable label area and diagnostic LEDs — simplify installation and management.

Suitable for

• Conference rooms and boardrooms for high-resolution presentations
• Auditoriums and lecture halls requiring long cable runs
• Banquet halls and event spaces with distributed AV equipment
• Museums and public display areas needing reliable, high-quality video distribution

How to use

Install the VE1843 at each end of the Cat 6A cable run and set each unit to the required mode (Tx or Rx). Connect HDMI sources and displays to the HDMI ports and attach control devices to the RS-232, IR or USB ports as needed. Use a single Cat 6A cable between units to carry video, audio, control signals and Ethernet. Mount the units using the built-in brackets, observe the diagnostic LEDs to verify operation, and write identifying labels in the front label area for easier management.

Recommendations

Use high-quality Cat 6A cable and proper shielding to maintain uncompressed 4K@60Hz 4:4:4 with HDR up to 100 m. Place the transceiver in a ventilated location to ensure passive heat dissipation and avoid covering the fin heat-sink. When deploying in multi-room setups, clearly label Tx/Rx roles and verify device firmware compatibility with connected matrix switches or splitters.
