ABOUT YOUR SWITCHER 2

The DA1917SX is a 2-in, 2-out VGA (VGA/SVGA/XGA) Auto Switcher with a built-in 1-in 2-out Distribution Amplifier. The DA1917SX may also be controlled manually through the use of a contact closure.

In its normal mode, the DA1917SX automatically switches to the active input source by sensing an incoming signal. If two input signals are active simultaneously, it will default to Input 2. Note that the DA1917SX may be custom modified at the factory upon request so that it will default to Input 1 instead of Input 2.

The DA1917SX offers two buffered outputs, both of which display the selected input signal. If only one output is used, it is not necessary to terminate the unused output.

The DA1917SX can be controlled manually by connecting a latching contact closure control to its 2.5mm mini-coaxial remote control jack. The DA1917SX comes with a small switch and a 6 foot cable (part # RC5203CC) which performs this control function, or the contact closure may be made from a control system. When the contact closure control is connected to the DA1917SX, an “open” position will select Input 1 and a “closed” position will select Input 2.

Although the DA1917SX is designed primarily to handle VGA-type (RGBHV) signals, it can also be used to pass Composite Video, S-Video, and Component Video signals through its Red, Green, and Blue channels. This may require the use of adapter cables to convert from a 15-pin HD connector to BNC connectors.

The DA1917SX is perfect for applications that require one local monitor to share two computers. It is also ideal for use in applications that make use of wall or floor plates for auto switching.

The DA1917SX may be mounted to furniture or other suitable surfaces using optional hardware.
