CNV-LKV671KVM-TX specification sheet

Overview:

Lenkeng LKV671KVM HDMI KVM Extender TX for 4K 30Hz over 100m CAT6/6A/7
The Lenkeng LKV671KVM transmitter is designed for long-distance HDMI and USB KVM signal extension over a single CAT6, CAT6A, or CAT7 cable. It delivers stable 4K video transmission up to 100 meters while maintaining near zero latency, making it suitable for control rooms, digital signage, conference environments, and professional AV installations.

This model, part number CNV-LKV671KVM-TX, is the transmitter unit of a point-to-point or one-to-many KVM extension system and is engineered to maintain signal integrity without compression.

Description:

The LKV671KVM TX unit enables high-performance HDMI and USB KVM extension with support for 4K UHD video and real-time responsiveness. It combines HDMI loop-out functionality for local monitoring with EDID passback to ensure consistent display recognition across connected devices. Built for professional environments, it supports stable transmission over long distances using standard structured cabling, reducing the need for direct HDMI runs and improving installation flexibility.

Features:

Long Distance 4K HDMI KVM Transmission Over CAT Cable
The system is built to extend HDMI and USB KVM signals up to 100 meters over a single CAT6/6A/7 cable. It supports 4K at 30Hz alongside a wide range of lower resolutions for compatibility with legacy and modern display systems. This makes it suitable for distributed AV setups where source equipment must be located far from the display or control station.

Stable Zero Latency Signal Extension Performance
Using advanced video processing, the LKV671KVM TX maintains near zero latency transmission without compression artifacts. This ensures smooth real-time control for keyboard and mouse operations, which is critical for interactive applications such as system monitoring, control rooms, and industrial environments.

Connectivity and Interface Layout
The transmitter provides flexible connectivity for professional integration. Key interfaces include HDMI input, HDMI loop-out, USB for KVM functionality, and RJ45 output for CAT cable transmission.

Key interface points:

• 1 x HDMI input (Type A, female, 19-pin)
• 1 x HDMI loop-out for local display monitoring
• 1 x USB port for KVM control
• 1 x RJ45 output for CAT6/6A/7 transmission
