• Review the contents of this user manual

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).

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

This equipment is to be used only inside a building. It may only be connected to other equipment that is installed inside a building.

2.2 Safety Instructions

Caution: There are no operator serviceable parts inside the unit

Warning: Use only the power cord that is supplied with the unit

Warning: Do not open the unit. High voltages can cause electrical shock! Servicing by qualified personnel only

Warning: Disconnect the power and unplug the unit from the wall before installing

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 go to our recycling pages at http://www.kramerelectronics.com/support/recycling/.

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

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.

4 Installing in a Rack

This section provides instructions for rack mounting the unit.

Before installing in a rack, be sure that the environment is within the recommended range:

OPERATING TEMPERATURE:	0° to +40°C (32° to 104°F)
STORAGE TEMPERATURE:	-40° to +70°C (-40° to 158°F)
HUMIDITY:	10% to 90%, RHL non-condensing

CAUTION!

When installing on a 19" rack, avoid hazards by taking care that:

1. It is located within the recommended environmental conditions, as the operating ambient temperature of a closed or multi unit rack assembly may exceed the room ambient temperature.
2. Once rack mounted, enough air will still flow around the machine.
3. The machine is placed straight in the correct horizontal position.
4. You do not overload the circuit(s). When connecting the machine to the supply circuit, overloading the circuits might have a detrimental effect on overcurrent protection and supply wiring. Refer to the appropriate nameplate ratings for information. For example, for fuse replacement, see the value printed on the product label.
5. The machine is earthed (grounded) in a reliable way and is connected only to an electricity socket with grounding. Pay particular attention to situations where electricity is supplied indirectly (when the power cord is not plugged directly into the socket in the wall), for example, when using an extension cable or a power strip, and that you use only the power cord that is supplied with the machine.

To rack-mount a machine:

1. Attach both ear brackets to the machine. To do so, remove the screws from each side of the machine (3 on each side), and replace those screws through the ear brackets.

Technical line drawing of a mechanical bracket assembly with bolts and rods (no text or symbols)

1. Place the ears of the machine against the rack rails, and insert the proper screws (not provided) through each of the four holes in the rack ears.

Note:

• In some models, the front panel may feature built-in rack ears
- Detachable rack ears can be removed for desktop use
• Always mount the machine in the rack before you attach any cables or connect the machine to the power
- If you are using a Kramer rack adapter kit (for a machine that is not 19"), see the Rack Adapters user manual for installation instructions available from our Web site

5 Connecting the VP-438

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.

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).
