KVM extender Transmitter & receiver Vivolink VLUSBCEXT151 HDMI USB Wired 70m

The Vivolink VLUSBCEXT151 is a USB-C KVM extender kit designed for meeting rooms to transmit HDMI video and USB device signals (for example cameras, microphones and touch panels) over a wired CAT6a connection. Using the HDBaseT VS3000 chipset, the kit supports long-distance transmission up to 70 m at 4K@30Hz and up to 40 m at 4K@60Hz 4:4:4. The kit includes one transmitter with a USB-C input for a laptop, a 100W USB-C power pass-through port (charger not included) and a USB-A port for local devices, plus one receiver with an HDMI 4K output and four USB 2.0 ports for peripherals at the screen side. Supported display modes include DisplayLink, DP Alt Mode and DisplayPort.

Advantages

The VLUSBCEXT151 provides a single-cable AV and USB extension solution for boardrooms and huddle spaces, enabling laptop connectivity and device control at the display while maintaining high-resolution video quality over long distances. The transmitter’s 100W USB-C power pass-through lets you connect an external charger to power or charge a laptop, and the included transmitter and receiver pair simplifies installation. HDBaseT 3.0 compatibility ensures reliable signal integrity over CAT6a cabling.

How to use

Connect the transmitter’s USB-C input to the laptop and, if required, connect a USB-C charger to the transmitter’s 100W power port to provide laptop power. Use CAT6a cable between the transmitter HDBaseT output and the receiver (observe recommended maximum lengths depending on desired resolution). Connect the receiver’s HDMI output to the display and plug USB peripherals such as a PTZ camera, soundbar or touch panel into the receiver’s USB 2.0 ports. Ensure the single supplied power adapter is connected to either the transmitter or receiver as needed.

Recommendations

For best performance use certified CAT6a cabling for runs approaching maximum distances, verify your laptop’s DisplayPort Alt Mode or DisplayLink compatibility, and use a USB-C charger rated for 100W when laptop power is required. Avoid mixing lower-grade cables to preserve 4K@60Hz 4:4:4 signal integrity.
