4K Auto-Switcher / Scaler Kit over Long Reach HDBaseT

The KIT-400 is a high-performance, two-piece auto-switcher/scaler kit for carrying 4K HDMI and VGA video over long-reach HDBaseT. It includes the KIT-400T transmitter/switcher and the KIT-400R receiver/scaler, creating a defined path from the selected source to the connected display. The transmitter converts the user-selected input signal into HDBaseT. At the display end, the receiver converts the HDBaseT signal to HDMI, then up- or down-scales the picture to match the resolution of the HDMI monitor. At the highest stated format, the system extends video up to 40m (130ft) over CAT copper cabling.

Ideal Use Cases

The KIT-400 is suited to signal paths that require selectable HDMI or VGA source support while placing an HDMI monitor away from the source equipment. Its combined transport and scaling functions address installations in which signal type, transmission distance, and display resolution must all be managed within the same system.

• Extending a user-selected HDMI or VGA source to a remotely located HDMI monitor.
• Carrying video over CAT copper cabling where conventional source-to-display cable reach is insufficient.
• Supporting 4K@60Hz 4:2:0 video across distances up to 40m (130ft).
• Matching the received picture to the HDMI monitor through receiver-side up- or down-scaling.
• Reaching farther than 40m when lower HD video resolutions are used, subject to the unspecified limits of those formats.

Why Choose This Model

The principal advantage of the KIT-400 is the coordinated transmitter, switcher, receiver, and scaler design. Both components are included: the KIT-400T handles the selected source and converts it for HDBaseT transmission, while the KIT-400R restores HDMI at the receiving end and performs the required picture scaling. This arrangement combines source handling, long-reach transport, format conversion, and resolution matching in one kit. It is particularly relevant when the selected source resolution does not directly match the HDMI monitor, since the receiver can scale the picture upward or downward for the connected display.

Installation and Integration

The signal flow begins with the selected HDMI or VGA input at the KIT-400T transmitter/switcher. The transmitter converts that signal into HDBaseT for transport over CAT copper cabling. At the other end of the cable run, the KIT-400R receives the HDBaseT transmission, converts it to HDMI, and feeds the HDMI monitor. Scaling occurs within the receiver so the delivered picture can match the monitor resolution. For a 4K@60Hz 4:2:0, 24bpp signal, the stated maximum extension distance is 40m (130ft). The source data also specifies further reach at lower HD resolutions, although it does not provide a separate maximum distance for those formats. This distinction should be considered when planning the required resolution and cable-run length.

Performance Highlights

The KIT-400 supports video up to 4K@60Hz with 4:2:0 color sampling and 24bpp color depth. Its listed bandwidth is 18Gbps, and the stated maximum refresh rate is 60Hz. The system preserves the practical benefit of 4K delivery across a 40m (130ft) CAT copper cable run while also accommodating lower HD formats over greater distances. At the receiver, bidirectional scaling capability means the picture can be up-scaled or down-scaled according to the resolution of the HDMI monitor rather than being limited to only one scaling direction.

What Makes It Different

This model does more than convert HDBaseT back to HDMI at the display. The transmitter and receiver perform distinct roles across the complete signal path: the KIT-400T manages the user-selected input and prepares it for HDBaseT transmission, while the KIT-400R handles HDMI conversion and display-resolution scaling. Support for both HDMI and VGA source signals also gives the kit a role in systems containing digital and legacy video sources. Its published 18Gbps bandwidth, 60Hz refresh rate, 4K transmission format, and 40m reach provide clearly defined performance targets for planning an installation without attributing unsupported connector counts or additional network functions to the system.

Final Assessment

The KIT-400 is a focused choice for extending a selected HDMI or VGA video source over long-reach HDBaseT and delivering a resolution-matched HDMI signal to a monitor. Its paired KIT-400T and KIT-400R architecture integrates transmission conversion with receive-side up- or down-scaling. For applications requiring up to 4K@60Hz 4:2:0, 24bpp video over as much as 40m (130ft) of CAT copper cabling, it provides a clearly specified combination of switching, extension, conversion, and scaling capabilities.
