What is a

Distribution

Amplifier?

What is the Serial Distribution System?

Are the outputs of the

DA1904SX

buffered?

What does buffered output mean?

Which type of signal format may I pass through the DA1904SX?

Answer

A Distribution Amplifier is a device that allows you to connect a single video source to multiple display devices, such as monitors or projectors used in presentation applications.

The Serial Distribution System is a system, which uses the concept of creating

ahigh-resolution video bus in large distribution applications with many displays. This system provides a lower cost and a higher performance alternative to the concept of feeding “home runs” to a single large distribution amplifier.

The DA1904SX has two outputs: one 15-pin HD loop output and one 5-BNC RGBHV buffered output

Buffered output means that the output signal is isolated from the input signal. This means that the loaded output does not affect the input or any other output on the device. A buffered output may vary in terms of the gain or peaking adjustments made to the video signal.

The DA1904SX can pass high-resolution RGBHV, RGBS, RGsB, and RsGsBs format computer video signals. Many display devices that use a 15-pin HD (VGZ-type) connector can only accept RGBHV

equipment to be used in system.

TROUBLESHOOTING GUIDE 10

We have carefully tested and have found no problems in the supplied DA1904SX unit; however, we would like to offer the following suggestions:

∙Make sure that the correct power adapter is connected to the unit.

∙Please make sure that the input amplitude of the analog signal is less than 1.5V.

∙Please use the Altinex supplied external adapter (9V, 500mA).

∙Please make sure that the proper quality of cables is used. We recommend Altinex made cables for the best results.

∙If a problem arises after continuous usage at higher voltage, higher temperature, higher humidity, or at other extreme environmental conditions, please correct the problem.
