Installation
The Extron P/2 DA1 USB is a one input, one output VGA line driver.
It boosts the video signal between a laptop or desktop computer (input device) and a monitor or large screen projector (output device).
Features
• The P/2 DA1 USB accepts and outputs SVGA, VGA, XGA
RGBHV, RGBS, RGsB, and RsGsBs signals.
• The gain/peaking switch increases video signal voltage to
compensate for signal degradation caused by long cables.
Installation
To install the P/2 DA1 USB, do the following:
1. Turn off power to the input and output devices, and unplug
2. Connect the computer to the 15-pin HD male input
3. Connect the output device to the 15-pin HD female output
4. Plug the P/2 DA1 USB’s power connector into the
5. Reattach power cords, and apply power to the the input

and output devices.
Many laptop computers have an external video port, but they
require special commands to output the video to that
connector. Also, many laptops’ screens shut off after the port
is activated. See the computer’s user’s guide for details, or
contact Extron for a list of laptop keyboard commands.

If the signal cable between the P/2 DA1 USB and the
output device is shorter than approximately 125 feet, and
the gain switch is set 50% or 100%, the image may be
overcompensated. If the edges of the image seem to exceed
their boundaries, or if thin lines and sharp edges look thick
and fuzzy, try changing the gain/peaking setting.
