Product information

Description

The StarTech ST121HDBTE AV transmitter & receiver extends HDMI signals up to 230 ft (70 m) over a single CAT5e or CAT6 cable using HDBaseT technology. It supports Ultra HD 4K (4096 x 2160) and Full HD 1080p resolutions, transmits uncompressed HDMI audio and video, and offers Power over Cable (POC) so the receiver can be powered from the transmitter's power source. The compact black units are suitable for installations that require long-distance HDMI distribution while preserving image and audio quality.

Advantages

HDBaseT delivers zero-latency transmission of uncompressed HDMI video and audio along with additional signals such as Ethernet, IR and RS-232 over a single CAT5e/6 cable. The ST121HDBTE supports 4K at long range and 1080p up to the full 70 m, reducing signal degradation compared with long HDMI cables. Power over Cable simplifies installation by allowing one power source to power both transmitter and receiver. The kit includes mounting hardware and is TAA compliant, with a 2-year manufacturer warranty.

Suitable for

Digital signage in shopping centres, airports and transport hubs
AV distribution in schools, hospitals and corporate buildings
Stadiums, auditoriums and conference rooms requiring remote displays
Industrial or remote areas where power outlets are limited

How to use

Connect the HDMI source (PC, media player, set-top box) to the transmitter HDMI input and connect the display to the receiver HDMI output. Run a single CAT5e or CAT6 cable between the transmitter and receiver RJ-45 ports. Power the transmitter with the supplied 12V adapter; with Power over Cable enabled the receiver can be powered through the same cable, eliminating the need for a local power outlet. Use the included mounting hardware to secure the units where required and verify signal and resolution settings on the source and display.

Usage recommendations

For best results, use good-quality Cat5e or Cat6 cable in continuous runs without patch panels where possible, verify cable terminations, and confirm source and display settings support the intended resolution (4K or 1080p). Keep cable runs away from strong EMI sources and use shielded cable if required by the environment.
