Vivolink VLHDMIEXT416 AV extender AV vysielač a prijímač čierna

The VivoLink VLHDMIEXT416 AV extender kit includes a transmitter and a receiver designed to extend HDMI, control and audio signals over Cat5e cabling. The kit supports resolutions up to 3840 x 2160 (4K) and is HDMI 1.4 and HDCP 2.2 compliant. The system provides IR pass-through, RS-232 control and PoC (Power over Cable) functionality with a single PSU included. The receiver also features relay outputs for projector screen control while the transmitter offers audio de-embed for feeding an external audio system. Typical installations include meeting rooms, residential AV setups and digital signage where AV and control signals must be extended.

Advantages

The VLHDMIEXT416 transmits high-resolution video and control signals over Cat5e, supporting point-to-point links up to 70 m at 1080p and 40 m at 4K. Built-in audio de-embedding on the transmitter enables easy connection to sound systems without extra converters. Relay outputs on the receiver allow direct control of a motorised projector screen via RS-232 commands. The kit’s compliance with HDMI 1.4 and HDCP 2.2 ensures compatibility with common source devices, while the included single power supply and PoC support reduce cable clutter.

How to use

Connect the HDMI source to the transmitter unit and run a Cat5e cable from the transmitter to the receiver. Connect the display to the receiver’s HDMI output and, if required, connect the transmitter’s de-embedded audio output to an external audio device. Use the included power supply to power the units or enable PoC where supported. For control integration, connect IR emitters/receivers and RS-232 cables as needed; program the receiver relay outputs with the projector or screen RS-232 command set to control up/down movements.

Recommendations

For reliable 4K performance keep cable runs within the specified 40 m for 4K and use quality Cat5e or better cabling; when longer runs are needed, consider lowering resolution to 1080p to reach the 70 m range. Verify RS-232 command compatibility with your screen or projector manufacturer before installation.
