ABOUT YOUR SWITCHER 2
The DA1917SX is a 2-in, 2-out VGA
(VGA/SVGA/XGA) Auto Switcher with a built-in 1-in
2-out Distribution Amplifier. The DA1917SX may
also be controlled manually through the use of a
contact closure.
In its normal mode, the DA1917SX automatically
switches to the active input source by sensing an
incoming signal. If two input signals are active
simultaneously, it will default to Input 2. Note that
the DA1917SX may be custom modified at the
factory upon request so that it will default to Input 1
instead of Input 2.
The DA1917SX offers two buffered outputs, both of
which display the selected input signal. If only one
output is used, it is not necessary to terminate the
unused output.
The DA1917SX can be controlled manually by
connecting a latching contact closure control to its
2.5mm mini-coaxial remote control jack. The
DA1917SX comes with a small switch and a 6 foot
cable (part # RC5203CC) which performs this
control function, or the contact closure may be
made from a control system. When the contact
closure control is connected to the DA1917SX, an
“open” position will select Input 1 and a “closed”
position will select Input 2.
Although the DA1917SX is designed primarily to
handle VGA-type (RGBHV) signals, it can also be
used to pass Composite Video, S-Video, and
Component Video signals through its Red, Green,
and Blue channels. This may require the use of
adapter cables to convert from a 15-pin HD
connector to BNC connectors.
The DA1917SX is perfect for applications that
require one local monitor to share two computers. It
is also ideal for use in applications that make use
of wall or floor plates for auto switching.
The DA1917SX may be mounted to furniture or
other suitable surfaces using optional hardware.
