Question

Answer

1

What is a
Distribution
Amplifier?

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.

2

What is the
Serial
Distribution
System?

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

3

Are the
outputs of
the

DA1904SX

buffered?

The 

DA1904SX

 has two

outputs: one 15-pin HD loop
output and one 5-BNC
RGBHV buffered output

4

What does
buffered
output
mean?

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.

5

Which type
of signal
format may I
pass through
the

DA1904SX

?

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

format signals. Confirm the
compatibility of the display
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.
