The DA1914SX is a 2-In 1-Out RGBS Auto Switcher with manual remote capability via contact closure. Utilizing 4 Female BNC connectors for each input and output, the DA1914SX can pass RGBS, RGsB, Component Video, S-video and Composite Video signals. The DA1914SX has a fully buffered output.

The DA1914SX offers a Sync Source switch, enabling it to auto-switch RGBS format signals when placed in the "Sync" position, and to auto-switch RGsB and Composite Video signals when placed in the "Green" position. Composite Video signals must be passed through the Green channel if auto-switching is necessary. When two active sources are present, the DA1914SX will select the default input, Input 2.

The DA1914SX can be controlled manually by connecting a latching contact closure control to its 2.5-mm mini-coaxial remote control jack. The DA1914SX comes with small switch with a 6 foot cable (part # RC5203CC) that performs this function, or the contact closure may be made from a control system. The contact closure acts as a "push", switching back and forth between two active sources or switching between "on" and "off" if 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.

The DA1914SX may be mounted to furniture or other suitable surfaces using optional hardware.
