SWITCHERS

4.1 AUTO-SWITCH MODE
The DA1917SX automatically selects the active
source by sensing the incoming sync or video
signals. If you are switching a RGsB signal, the
DA1917SX will automatically sense the sync
from the Green channel. When two active
sources are present, the DA1917SX selects
Input 2 as the default.
4.2 MANUAL SWITCH MODE
The DA1916SX can be controlled manually by
connecting a contact closure control switch to
the Channel Select port of the DA1917SX. This
port uses a 2.5mm mini-coaxial remote control
jack and is located next to the Input 2. (Note that
the connector used for the Channel Select port
is the same as the power connector used for the
unit. (No damage will occur if the power is
accidentally connected to the Channel Select
port).
APPLICATION DIAGRAM 5
Altinex offers a remote control switch with a 12
feet cable (Part # RC5203CC) which performs
this control function. The DA1917SX can also be
controlled using AV control systems.
When a remote control switch is connected to
the Channel Select port, Input 1 will be selected
if the Channel Select Contact is “open” and Input
2 if the Channel Select Contact is “closed”.
It does not matter whether there is one active
signal or two active signals – the switching will
be identical. The LED lights next to each of the
inputs will indicate which input is selected.
Both Outputs of the DA1917SX are fully
buffered and are capable of driving a signal over
200 feet of high quality coaxial cable.
