Daisy Chaining the VSW 2VGA A

Up to ten VSW 2VGA A switchers can be daisy chained together with each switcher's input separately fed and controlled by an optional accessory interface, the VSW I AAP (part #70-529-xx). Figure 1-1 is an example of how several such switcher-interface combinations can be daisy chained together in a boardroom environment.

Figure 1-1 — Daisy chaining the multiple switchers

By default, all switchers are set to input 2 as the active input; therefore, in a daisy chain of switchers the VGA and audio signals flow from one switcher to input 2 of the next switcher in the chain. The switchers are daisy chained in this fashion until the last switcher in the daisy chain outputs to a projector and audio amplifier.

Up to ten switchers can be daisy chained together without any degradation in picture quality. One power supply powers up to five switchers.
