Where to Buy

Product Description

The VLEX-CD14U2100 is a long-reach HDBaseT extender that carries USB-C video, USB 2.0, IR, and RS-232 signals up to 100m/328ft over a single Cat5e/6 cable, converting the USB-C DisplayPort ALT Mode signal to standard HDBaseT for transmission and reconstructing it at the receiver. Video resolution reaches 4K@60Hz at full 4:4:4 chroma sampling, with USB Type-C DisplayPort 1.4a ALT Mode and HDCP 2.3/2.2/1.x compliance across up to 32.4Gbps of video bandwidth (HBR3/HBR2/HBR/RBR).

Bi-directional IR and RS-232 pass-through let installers control the source or display from either end of the run without a separate control cable, while advanced EDID management (COPY TV/STD) and audio de-embedding at the receiver round out a compact, plug-and-play design. Bi-directional PoC simplifies power delivery for installations built around single-cable USB-C laptops and docking scenarios that need to reach displays beyond standard USB-C cable length.

Frequently Asked Questions

What is the maximum distance and resolution for the VLEX-CD14U2100?
The VLEX-CD14U2100 extends 4K@60Hz 4:4:4 USB-C DisplayPort ALT Mode video up to 100m/328ft over a single Cat5e/6 cable, with up to 32.4Gbps of video bandwidth and HDCP 2.3/2.2/1.x compliance.

Does the VLEX-CD14U2100 charge a connected laptop?
The transmitter includes a dedicated USB-C CHARGE input port separate from the USB-C IN video port, allowing a laptop's charging cable to be routed through the same unit. Confirm supported wattage with the data sheet before specifying for high-draw laptops.

Does this extender support control signals in addition to video?
Yes. The VLEX-CD14U2100 passes bi-directional IR and RS-232 control signals over the same Cat cable as the USB-C video signal, so remote and serial automation continue to work across the full 100m run.

Can I power this extender from one end only?
Yes. The VLEX-CD14U2100 supports bi-directional PoC (Power over Cable), so a single 24V/1A power supply at either the transmitter or receiver can power both units over the Cat cable.

Is the VLEX-CD14U2100 compatible with laptops that don't support DisplayPort ALT Mode over USB-C?
No. The extender requires a USB-C source with DisplayPort 1.4a ALT Mode support. For DisplayPort-only sources, use the VLEX-D14U2100; for HDMI sources, use the VLEX-H20U2100 or VLEX-H21U2100.

What audio formats does the VLEX-CD14U2100 pass through?
The extender passes LPCM, Dolby Digital/Plus/EX, Dolby TrueHD, Dolby Atmos, DTS, DTS-EX, DTS-96/24, DTS High Res, DTS-HD Master Audio, and DTS:X, with audio de-embedding available at the receiver via the 3.5mm analog output.
