1 What is a
Switcher?
A Switcher is a device that
allows you to connect
multiple video sources to a
single display and select
between the sources.
2 When do I
use the
DA1914SX?
If you have two computers
and you want to display
them on a single monitor,
you would use the
DA1914SX between the
computers and the monitor,
using cables to interconnect
the pieces. The switcher
would then allow you to
select which computer would
be displayed on the monitor
at any given time.
3 What kind of
signal
formats may
I pass
through the
DA1914SX?
The DA1914SX can pass
RGBS, RGsB, Component
Video (Y, R-Y, B-Y), S-Video
(Y/C), and Composite Video
signals.
4 Is the output
of the
DA1914SX
buffered?
Yes, the DA1914SX offers a
fully buffered output.
5 Why do I
need the
Sync Source
switch?
The DA1914SX offers a
Sync Source switch,
enabling it to auto-switch
RGBS signal formats when
placed in the SYNC position,
and auto-switch RGsB and
Composite Video signals
when placed in the GREEN
position.
6 How far can I
run a signal
through the
DA1914SX?
The output of the DA1914SX
allows signals to be driven
through 100 feet of cable
depending on the cable
quality and the source signal
resolution without
degradation of the image
quality.
TROUBLESHOOTING GUIDE 10
We have carefully tested and have found no
problems in the supplied DA1914SX unit; however,
we would like to offer the following suggestions:
• Please make sure that you have the correct
setting Sync Source Switch. If you pass
RGBS, the signal format switch must be in the
SYNC position. If you pass RGsB or
Composite Video signal formats, the switch
must be in the GREEN position.
• 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.
