VP-438 - Getting Started
Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check
if firmware upgrades are available (where appropriate).
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.
i
!
2 Getting Started
We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
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-438 away from moisture, excessive sunlight and
dust

2.2 Safety Instructions
2.3 Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC
aims to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN
facility. For details of Kramer’s recycling arrangements in your particular country

VP-438 - Overview
3 Overview
The Kramer VP-438 is a high-quality presentation switcher and scaler. It accepts
one of 10 inputs: four HDMI signals, two computer graphics signals on 15-pin HD
connectors, two composite video signals on RCA connectors and two component
video signals (also known as Y, Pb, Pr, Y, Cb, Cr and YUV; compatible with both
SD and HD component) on RCA connectors. It scales the video, embeds the
audio, and outputs the signal to the HDMI output, as well as to a computer
graphics output and an RGBHV video output with digital audio and analog stereo
audio outputs.
The VP-438 Presentation Switcher/Scaler:
Is HDTV compatible and the resolution can be up- or down-scaled
Is HDCP compliant, the HDCP (High Definition Content Protection) license
agreement allows copy−protected data on the HDMI input to pass only to the
HDMI output
Output signal is available in three formats: 1 HDMI and 2 RGBHV (on 5 BNC
connectors, and one 15−pin HD connector)
Has analog audio inputs, which include volume control, and digital (S/PDIF)
and analog stereo audio outputs
Automatically detects and selects the audio source for the HDMI input.
Default selection is HDMI – if this is not present, then the machine uses the
audio from the analog input
Comes with an On-Screen Display (OSD) for easy setup and adjustment,
accessible via the IR remote control and via the front-panel buttons
Has a non-volatile memory that retains the last settings used
Supports firmware upgrade via RS-232
VP-438 - Overview
5
Control your VP-438:
Directly, via the front panel push buttons
By RS-232 serial commands transmitted by a touch screen system, PC, or
other serial controller
Remotely, from the infrared remote control transmitter
The VP-438 is housed in a 19” 1U rack mountable enclosure, with rack “ears”
included, and is fed from a 100-240V AC universal switching power supply.

Always switch off the power to each device before connecting it to your
VP-438. After connecting your VP-438, connect its power and then
switch on the power to each device.
i
5 Connecting the VP-438
To connect your VP-438, as illustrated in the example in Figure 3, do the following:
You do not have to connect all the inputs and outputs, connect only those that are required.
1. Connect an HDMI source (for example, a DVD player) to each of the HDMI
VIDEO INPUT connectors (from 1 to 4).
Alternatively, you can connect the DVI connector on the DVD player to the HDMI
connector on the VP-438 via a DVI-HDMI adapter. When using this adapter, you can
connect the audio signal via the terminal block connector.
2. Connect a computer graphics source to the PC 1 15-pin HD VIDEO INPUT
connector.
3. Connect a composite video source (for example, a composite video player)
to both CV VIDEO INPUT RCA connectors.
4. Connect a component video source (for example, a component video player)
to the COMP 1 PR, PB and Y, VIDEO INPUT RCA connectors.
5. Connect the audio input signals to the AUDIO INPUT terminal block
connectors, as required (not shown in Figure 3).
6. Connect the RGBHV VIDEO OUTPUT BNC connectors to an RGBHV
acceptor (for example, an RGBHV display).
7. Connect the HDMI VIDEO OUTPUT connector to an HDMI acceptor (for
example, a plasma display).
8. Connect the VGA VIDEO OUTPUT 15-pin HD connector to a VGA acceptor
(for example, a projector).
9. Connect the audio output signals to the AUDIO OUTPUTS stereo analog
audio acceptor and/or the digital audio acceptor, as required (not shown in
Figure 3).
10. Connect the power cord (not shown in Figure 3).
