9-2-1-1. About Changeover (Web)
The changeover function is supported for the main input, SDI 1. If the SDII 1 input
encounters a problem, Changeover switches the input to input SDI 2. However, if SDI 2
also encounters the same problem, a changeover will not occur. Conditions to determine
problem occurrence can be selected in the previously described menus Video Trigger
through Silence Trigger. Input selection under Input Select cannot be changed while
Changeover is enabled. Input Select must be set to SDI 1 to enable Changeover. Whether
a changeover has been performed can be checked in the 9-7-5 Changeover Status menu,
which allows you to know what caused the changeover. To reset the Changeover Status
menu, set Changeover to Disable.
