ABOUT YOUR SWITCHER
2
The
DA1914SX
is a 2-in, 1-out RGBS Auto
Switcher with manual remote capability through
contact closure. Using four Female BNC
connectors for each input and output, the
DA1914SX
has a fully buffered output.
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. Composite Video signals
must be passed through the Green channel when
auto-switching is necessary. When two active
sources are present, the
DA1914SX
will select the
default input, which is Input 2.
The
DA1914SX
can be controlled manually by
connecting a latching contact closure control to its
2.5mm mini-coaxial remote control jack. The
DA1914SX
comes with a small switch and a 6 foot
cable (part#
RC5203CC
) that performs the manual
switch function, or contact closure may be made
from a control system. The contact closure acts as
a “push”, switching back and forth between two
active sources and switching between ON and OFF
when a single active source is on Input 1. If a
single active source is on Input 2 (the default), the
manual control will not push to Input 1.
In auto-switch mode, the
DA1914SX
is perfect for
applications in which a user plugs in one of two
input plates at different locations. In manual mode,
the
DA1914SX
is great as an
ON/OFF switch or for simply switching between two
active computers.
The
DA1914SX
may be mounted to furniture or
other suitable surfaces using optional hardware.
