How does the iScan Pro detect incoming signals?
The iScan Pro detects which of the three possible input devices are turned on, and it switches to this input. With this capability, the user can switch inputs simply by turning one input device on or by turning another device off. The input priority switch on the front panel of iScan Pro specifies which of the inputs to use when there are multiple active inputs. If the iScan Pro is processing video from one input when a higher priority input becomes active, it will automatically switch to the new input.
