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.
Table 1. DA1914SX General
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.

4.3 MANUAL SWITCH MODE
4.1 INPUT AND OUTPUTS
The DA1914SX can be controlled manually by
connecting a contact closure control switch to its
2.5mm mini-coaxial remote control jack. Altinex
offers a remote control switch with a 6 foot cable,
(Part # RC5203CC), which performs the manual
switch function. The DA1914SX can also be
controlled using contact closure relays on a
control system.
The DA1914SX uses four Female BNC
connectors for each input and output. The
DA1914SX can pass RGBS, RGsB, Component
Video, S-Video, and Composite Video signals.
Video signals must be passed through Red,
Green, and/or Blue channels; Sync channel is not
designed to pass video. C-Video must be passed
through the Green channel.
When an active source is on INPUT 1, the manual
switch will not affect the input, and will not switch
to INPUT 2.
4.2 AUTO-SWITCH MODE
The DA1914SX automatically selects the active
source, by sensing the incoming sync. Sync
sensing occurs on the Sync channel for RGBS
signals and on the Green channel for RGsB or
Composite signals. The sync source switch should
be switched from SYNC to GREEN when using
RGsB or Composite Video sources. The
Composite source must be connected to the
Green channel in order for the auto-switcher to
work properly with composite video signals. When
both signals are present, the switcher will default
to INPUT 2.
When an active source is on INPUT 2, the manual
switch will act as an ON/OFF switch, forcing the
switcher to INPUT 1 when the contact closure is in
the CLOSED position.
When two active sources are present on INPUT 2
in the OPEN Switching Mode, the DA1914SX will
select INPUT 1. If the contact closure is in the
CLOSED position, and remains on INPUT 2, the
contact closure will switch to the OPEN position.
LED lights indicate the correct switching.
