Black Box KVXLCH-100 – 4K HDMI KVM Extender CATx with USB 2.0
Product Overview
The Black Box KVXLCH-100 is a CATx KVM extender that transmits 4K HDMI video, USB 2.0, serial (RS-232), and bidirectional audio over a single Cat6 cable to distances up to 100 meters, with local video output retained at the transmitter end. Designed for AV integrators deploying remote workstation access in control rooms, broadcast facilities, and commercial AV environments, the KVXLCH-100 delivers full-resolution 4K content from a host system to a remote operator station without signal degradation, while simultaneously maintaining a local console for on-site monitoring.
Product Description
The KVXLCH-100 is part of Black Box's KVX Series KVM Extenders, a product line engineered for commercial-grade reliability in demanding AV and IT infrastructure deployments. The unit supports 4K UHD HDMI video at up to 3840x2160 resolution, transmitted over Cat6 cable using HDBaseT-compatible technology, reaching remote operator positions up to 100 meters away. USB 2.0 extension allows keyboards, mice, webcams, and other peripherals to be located remotely from the host computer. The built-in serial port extends RS-232 communication for legacy control systems, touch panels, and automation controllers — particularly valuable in control rooms and broadcast environments. Bidirectional audio support allows microphone and speaker connections at both the local and remote ends. The local video output on the transmitter unit gives the equipment room or rack location a secondary display feed without requiring a separate video distribution device. This makes the KVXLCH-100 particularly well-suited for broadcast studios, government operations centers, command and control rooms, and commercial corporate AV systems.

Frequently Asked Questions
Does the KVXLCH-100 support 4K at 60Hz or only 30Hz?
The KVXLCH-100 supports 4K UHD video extension. At 4K resolution, the refresh rate achievable over CATx depends on the specific firmware and cable quality. For guaranteed 4K/60Hz performance, verify the cable run quality and refer to Black Box's compatibility documentation.
Can the KVXLCH-100 be used with a KVM switch to share one remote station across multiple computers?
Yes. The KVXLCH-100 can be paired with compatible Black Box KVM switches at the local (transmitter) end to allow a remote operator station to access multiple host systems. Refer to Black Box's KVX Series compatibility matrix for validated switch combinations.
Is the RS-232 serial extension useful for Crestron or AMX control systems?
Yes. The RS-232 serial port on the KVXLCH-100 is compatible with Crestron, AMX, Extron, and other RS-232-based control systems, allowing control signal extension to remote operator positions alongside the video and USB extension.
What type of Cat cable is required and does it need to be shielded?
Cat6 cable is recommended for 4K performance at maximum distance. Shielded (STP/FTP) cable is advisable in environments with significant electromagnetic interference, such as broadcast studios with high RF equipment density.
Does the unit support cascading or matrix configurations?
The KVXLCH-100 is a point-to-point extender. For matrix KVM configurations, Black Box's Emerald or DKM series platforms support multi-user, multi-computer matrix switching and extension.
