Introduction
1 Introduction
Dedication by Kramer Electronics since 1981, to the development and
manufacture of high quality video/audio equipment, makes the Kramer line
an integral part of the finest production and presentation facilities in the
world. In recent years, Kramer has redesigned and upgraded most of the line,
making the best even better! The Kramer line of professional video/audio
electronics is one of the most versatile and complete available, and is a true
leader in terms of quality, workmanship, price/performance ratio and
innovation. In addition to the VP-200Dxl XGA Differential Amplifier / DA
(Distribution Amplifier), we also offer excellent switchers and matrices,
presentation processors, interfaces, remote controllers and computer-related
products.
Congratulations on purchasing your Kramer Tools VP-200Dxl XGA
Differential Amplifier / DA. This product is ideal for using with:
ñ
ñ
Dual monitor remote applications (local or long range)
Presentation systems (for long distance, interference-free distribution and
cable equalization) requiring a local monitor and a large screen display such as
a projector, at close or remote locations

3 Overview
The high performance VP-200Dxl XGA Differential Amplifier / DA is a 1:2
1
Your XGA Differential Amplifier / DA
differential line amplifier / distributor for VGA/XGA signals that accepts one
input, provides correct buffering and isolation, and then distributes the signal
to 2 identical outputs.
In particular, the VP-200Dxl XGA Differential Amplifier / DA includes:
ñ
High-density 15 pin D connectors
ñ
Video bandwidth of 400 MHz, ensuring that it remains transparent even
at highest resolution UXGA modes (1600x1200)
ñ
ñ
An output level rotary control and a cable equalization rotary control
Special differential amplifying circuitry, which eliminates noise and hum
problems commonly found in long VGA/XGA lines
ID Bit control
Achieving the best performance means:
Connecting only good quality connection cables, thus avoiding
ñ
ñ
interference, deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables)
ñ
Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality and positioning your VP-200Dxl unit in a
location free from moisture and away from excessive sunlight and dust

4.1 Connecting the XGA Differential Amplifier / DA
To connect the VP-200Dxl, as the example in Figure 2 illustrates, do the
following:
1. Connect a XGA source (for example, a PC graphics card) to the INPUT
HD15F connector.
2. Release the ID Bit button2.
3. Connect the OUTPUT (HD15F connectors) to up to 2 acceptors, as
follows:
ñ
Connect the OUTPUT 1 (HD15F connector) to the acceptor 1 (for
example, a PC monitor)
Connect the OUTPUT 2 (HD15F connector) to the acceptor 2 (for
ñ
example, a projector)
4. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity.
5. Adjust the video EQ. (equalization) compensation and/or the video signal
level, if required.
1 Sometimes notebook computers refuse to output a VGA signal to an external VGA monitor if they do not detect the ID Bit
as ON (pin # 4 on the VGA connector). Set the ID Bit to ON using this button so that the notebook will output to an external
VGA monitor
2 However, if the source is a notebook (instead of a PC graphics card), push in the ID Bit button
