2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer VP-427 away from moisture, excessive sunlight and
dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

VP-427 - Overview
3 Overview
The Kramer VP-427 is a receiver/scaler for HDBaseT twisted pair, HDMI,
bidirectional RS-232 and IR signals. The unit receives an HDBaseT signal that it
converts to HDMI, IR and passed RS-232 signals. It up- or down-scales the picture
to match the resolution of the HDMI monitor.
The VP-427 also features:
An HDBaseT input
An HDMI output
A bidirectional RS-232 port for embedding/de-embedding control commands
in the HDBaseT data stream
Infrared input and output ports for controlling devices over the HDBaseT data
stream
Embedded audio supporting LPCM 2CH
Maintains constant sync on the output, even when the input video signal is
lost or interrupted
System range of up to 70m (230ft)
A built-in ProcAmp for convenient signal adjustment
An On-Screen Display (OSD) for easy setup and adjustment, accessible via
the front-panel buttons
A non-volatile memory that retains the last settings used
A freeze button
A USB connector for firmware upgrading
The machine is fed from an external 5V DC source, making it suitable for field
operation.
