Extron electronic MSW 4V, MSW 4SV manual Vertical interval switching, Rear panel connections

VersaTools® MSW 4V & 4SV, cont’d

Vertical interval switching

The MSWs switch inputs during the vertical interval of the video signal that is input on input 1. In a genlocked system, switching to any input is glitch-free if one of the genlocked devices is connected to input 1.

Rear panel connections

The MSW switches on the vertical interval of input 1. For seamless switching, ensure one of the genlocked devices is connected to input 1.

To select an input using a contact closure device, such as an Extron CCR 204 contact closure remote control (part #60-794-02) or a locally constructed device, momentarily short the pin for

You can also daisy chain multiple MSWs via the Contact connector for front panel control of all switchers; touch the input button on one MSW to switch all MSWs. Wire pin 1 to pin 1, pin 2 to pin 2, and so on.
