Extron electronic SCP 150 Video input, Installation, Features, Operation, Specifications

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 (in- put 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 their power cords.

2.Connect the computer to the 15-pin HD male input connector (see 1 in the “Operation” illustration below).

3.Connect the output device to the 15-pin HD female output connector (see 5 in the “Operation” illustration below).

4.Plug the P/2 DA1 USB’s power connector into the computer’s USB port.

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.

115-pin HD input connector (male)

2Power LED — Lights to indicate that the P/2 DA1 USB is on.

3Signal LED — Lights to indicate that an input signal is being received.

4Gain/peaking switch — Compensates for cable resistance and capacitance.

Normal — Output is the same level as input.

Medium — 50% of the total gain is applied. Peaking is applied.

Maximum — 100% of the total gain is applied. Peaking is applied.

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.
