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

1

The VP-438 Presentation Switcher / Scaler:

signals 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.

• Is HDTV compatible and the resolution can be up- or down-scaled

2

• 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

3

Control your VP-438:

via RS-232

• 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.

1 Also known as Y, Pb, Pr, Y, Cb, Cr and YUV; compatible with both SD and HD component

3.1 Recommendations for Best Performance

To achieve the best performance:

• Connect only good quality connection cables, thus avoiding interference,

deterioration in signal quality due to poor matching, and elevated noise­levels (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 and position

your Kramer VP-438 away from moisture, excessive sunlight and dust

3.2 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 go to our recycling pages at

http://www.kramerelectronics.com/support/recycling/.

6 Connecting the VP-438 Presentation Switcher / Scaler

To connect1 your VP-438, as illustrated in the example in Figure 2, do the
following

2

1. Connect an HDMI source (for example, a DVD player) to each of the

HDMI VIDEO INPUT connectors

:

3

2. Connect a computer graphics source to the PC 1 15-pin HD VIDEO

INPUT connector.

(from 1 to 4).

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 P

R, 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 2).

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 2).

10. Connect the power cord

4

(not shown in Figure 2).

1 You do not have to connect all the inputs and outputs, connect only those that are required

2 Switch OFF the power on each device before connecting it to your VP-438. After connecting your VP-438, switch on its

power and then switch on the power on each device

3 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

4 We recommend that you use only the power cord that is supplied with this machine

7.3 Connecting to VP-438 via RS-232

You can connect to the VP-438 via an RS-232 connection using, for example,
a PC. Note that a null-modem adapter/connection is not required.

To connect to the VP-438 via RS-232, connect the RS-232 9-pin D-sub rear
panel port on the VP-438 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.

1 Not applicable for embedded HDMI audio inputs

2 INDEPENDENT means that the audio muting is independent of the FREEZE and BLANK functions

3 FREEZE/BLANK means that when you FREEZE or BLANK the video, then the audio will be muted (the MUTE function

follows the FREEZE and the BLANK functions)

4 Enabled only when one of the HDMI inputs is selected

5 In this case, the embedded audio on the HDMI input is selected for an HDMI signal, or the analog audio input is selected if

the input is not HDMI (for example, for a DVI input signal)

6 In this case, the embedded audio in the HDMI signal is selected
