VP-438 - Getting Started

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

Go to http://www.kramerelectronics.com 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.

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

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.
