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.
