3 Overview
The high performance VP-200D XGA Differential Amplifier / DA is a 1:2
differential line amplifier / distributor for computer graphics signals that
accepts one input, provides correct buffering and isolation, and then
distributes the signal to two identical outputs.

Your VP-200D XGA Differential Amplifier / DA
In particular, the VP-200D XGA Differential Amplifier / DA includes:
ñ
High-density 15 pin D connectors
ñ
Video bandwidth of 420MHz, ensuring that it remains transparent for all
resolutions
ñ
ñ
Separate controls for output level and a cable equalization
Special differential amplifying circuitry, which eliminates noise and hum
problems commonly found in long XGA lines
ñ
ñ
ID Bit control
Is 12VDC fed
Achieving the best performance means:
Connecting only good quality connection cables, thus avoiding
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 and
positioning your VP-200D away from moisture, excessive sunlight and dust

5 Connecting the VP-200D XGA Differential Amplifier / DA
To connect your VP-200D XGA Differential Amplifier / DA, as the example in
Figure 4 illustrates, do the following2:
1. Connect a computer graphics source (for example, a computer) to the
INPUT HD15F connector.
2. Push in the ID Bit button.
3. Connect the OUTPUT HD15F connectors to up to 2 acceptors, as follows:
ñ
ñ
Connect the OUTPUT 1 to the acceptor 1 (for example, a projector)
Connect the OUTPUT 2 to the acceptor 2 (for example, a display)
4. Connect the 12V DC power adapter (wall transformer) to the 12V DC
socket and connect the transformer to the mains electricity.
5. If required, adjust the video EQ. and/or the video signal level.
It is recommended that you place the VP-200D at the far end, away from the
source, where the differential circuitry would be most effective.
