Vivolink VLHDMIEXT422 AV extender AV vysielač a prijímač čierna

The VivoLink VLHDMIEXT422 is an AV transmitter and receiver kit designed to extend HDMI, IR and RS232 control signals over Cat5e cable. The two-way PoC (Power over Cable) system supports bi-directional IR, RS232 and CEC control, is HDCP 2.2 compliant and can be powered from a single PSU. It supports resolutions up to 4096 x 2160 and is intended for point-to-point installations where AV and control signals need to be transmitted over distance.

Advantages

The VLHDMIEXT422 combines transmitter and receiver functionality in a compact kit and uses Cat5e cable for long-distance HDMI extension. PoC reduces cabling by allowing one power source to serve both units. The device supports HDCP 2.2 and bi-directional control signals (IR and RS232), enabling centralised control of displays and source equipment. Its AC input range (100–240 V) and included pair of units make it suitable for a variety of installation environments.

Suitable for

• Meeting rooms and conference spaces
• Residential AV setups where displays are distant from sources
• Digital signage and retail displays
• Control-system integrations requiring RS232 and IR pass-through

How to use

Connect the transmitter to the HDMI source and the receiver to the display using HDMI cables. Link the two units with a Cat5e cable using the designated RJ45 ports. If using PoC, connect the provided PSU to the designated unit; the other unit will receive power over the cable. Connect IR emitters/receivers and RS232 control lines as required for remote control or integration with control systems. Ensure source and display support the selected resolution and that HDMI cables and Cat5e cabling are properly terminated.

Recommendations

Use good-quality Cat5e cabling and proper terminations for reliable signal transmission. For distances near the maximum range, verify cable quality and minimise EMI sources. Confirm HDCP compatibility of source and display when transmitting protected content.
