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-427A 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-427A - Overview
3 Overview
The Kramer VP-427A 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-427A 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
A simultaneous analog audio output of the embedded HDMI audio
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.

4 Connecting the VP-427A
Always switch off the power to each device before connecting it to your
VP-427A. After connecting your VP-427A, connect its power and then
switch on the power to each device.
To connect the VP-427A as illustrated in the example in Figure 2:
1. Connect the output from an HDBaseT transmitter (for example, a TP-582T)
to the HDBT IN RJ-45 connector.
2. Connect the AUDIO OUT 3.5mm mini jack connector to an unbalanced
stereo audio acceptor (for example, an amplifier).
3. Connect the HDMI OUT connector to an HDMI acceptor (for example, a
display).
4. Connect an IR receiver to the IR IN 3.5mm mini jack.
5. Connect the IR OUT 3.5mm mini jack to an IR emitter.
6. Connect the RS-232 9-pin D-sub connector to an RS-232 port (for example,
a display).
7. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity (not shown in Figure 2).

4.1 RS-232 Control Over HDBaseT
You can connect to the transmitter/receiver system via an RS-232 connection
using, for example, a PC. Note that a null-modem adapter/connection is not
required.
To connect a PC via RS-232, connect the RS-232 9-pin D-sub rear panel port on
the transmitter/receiver system unit via a 9-wire straight cable (only pin 2 to pin 2,
pin 3 to pin 3, and pin 5 to pin 5 need to be connected) to the RS-232 9-pin D-sub
port on your PC.
