ABOUT YOUR SWITCHER 2
The DA1916SX is a 2-in, 1-out VGA
(VGA/SVGA/XGA) Auto Switcher with manual
remote capability through the use of a contact
closure.
The DA1916SX automatically switches to the active
input source by sensing an incoming signal. If two
input signals are active simultaneously, the
DA1916SX will default to Input 2. Please note that
the DA1916SX may be custom modified at the
factory upon request so that it will default to Input 1
instead of Input 2.
The DA1916SX offers both a main output for the
selected source and a loop output that always
passes through Input 1, regardless of which input is
selected. The main output is fully buffered and, if it
is not used, it must be terminated with a 75 Ohms
VGA termination plug (part # MS8000TP), which is
supplied with the unit.
The DA1916SX can be controlled manually by
connecting the contact closure control to its 2.5mm
mini-coaxial remote control jack. The DA1916SX is
packaged with a small switch and a six foot cable
(part # RC5203CC), which controls the DA1916SX
or the contact closure may be made from a control
system. When the contact closure control is
connected to the DA1916SX, an open position will
select Input 1 and a closed position will select
Input 2.
Although the DA1916SX is designed primarily to
handle VGA-type (RGBHV) signals, it can also be
used to pass RGBS and RGsB. It may also be
used to pass composite video, s-video, and
component video signals through red, green, and
blue channels. This may require the use of adapter
cables to convert a 15-pin HD connector to BNC
connectors.
The DA1916SX is perfect for applications that use
wall or floor plates for auto switching. It also works
very well as a building block for classroom training
systems in which the instructor’s signal is placed
alongside a bus (via the loop output) to each of the
student’s stations. The students own computer is
connected to Input 2.
The DA1916SX may be mounted to furniture or
other suitable surfaces using optional hardware.
