2.1 Quick Start
This quick start chart summarizes the basic setup and operation steps.

Overview

3 Overview
The VP-8K is a high-performance, HDTV compatible distribution amplifier
for computer graphics signals, with resolutions exceeding UXGA. It accepts
one computer graphics input, and outputs it to eight computer graphics
signals. In particular, the VP-8K features:
A high video bandwidth of 370MHz, ensuring that it remains transparent
even at high-resolution graphics modes such as UXGA (1600x1200)
An internal ID Bit control as well as internal KR-ISP™ technology,
which provides a sharp, stable image when the sync level is too low, by
restoring the sync signal waveform
A termination switch
A desktop-sized enclosure and it is 5V DC fed
To achieve the best performance:
Use only good quality connection cables to avoid interference,
deterioration in signal quality due to poor matching, and elevated noise
levels (often associated with low quality cables).
Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer VP-8K away
from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit
1
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

graphics card. Set to 75if the source is analog based, for
example, an RGBHV source with coaxial cable for sync
4 OUTPUT 15-pin HD (F) Connector Connect to the VGA/UXGA acceptors (from 1 to 8)
5 5V DC +5V DC connector for powering the unit
1 “Transistor-Transistor Logic” is a term used in digital electronics describing the ability of a device or circuit to be connected
directly to the input or output of digital equipment. Such compatibility eliminates the need for interfacing circuitry

To connect the VP-8K, as the example in Figure 2 illustrates:
1. Connect a computer graphics source to the VGA / UXGA INPUT 15-pin HD
(F) connector.
2. Connect the VGA / UXGA OUTPUT 15-pin HD (F) connectors to up to
1
eight acceptors (for example, displays).
3. Connect the 5V DC power adapter to the power socket and connect the adapter
to the mains electricity (not illustrated in Figure 2).
4. Set the SYNC 75/ Hi-Z (TTL) switch to the Hi-Z (TTL) position.
