Automatic Signal Detection

The VS-42UHD can automatically detect the presence of a video signal on an input
based on the presence of a video sync or clock signal.

Input Switching Modes

5.2.1 Manual Mode
In Manual switching mode, routing is performed according to the front panel button
selection or according to the remote command selection.
5.2.2 Automatic Mode
Automatic switching can be performed in either of the following ways:
•
Input priority. Upon detection of an active input, the input with the highest
priority is automatically selected. Input priority is from the lowest input number
(1) to the highest (4)
•
Last Connected. The device automatically selects the most recently
connected input. Should this source become inactive, the device
automatically switches to the last connected input that was active. When
turning the device on and more than one input is active, the input with the
highest priority is selected
If a manual selection is made when the device is in Automatic mode, the device
enters Manual Override mode. The manually selected input remains selected as
long as it is active. When a manually selected input becomes inactive, the device
returns to Automatic mode.
