Making Switcher Processor Gpi Output Settings - Sony MVS-8000X User Manual

powering the system off, the action triggered by the GPI
may start immediately before the power goes off and the
power may go off before the action is completed. This
may corrupt the setup settings. It is therefore
recommended to use Level Enable to avoid such a
situation.
• If "Format" is selected for "Action" when the format
converter is used on the switcher, you can set the
conversion format of the format converter for "FC Input
1-4," "FC Input 5-8," "FC Input 9-12" (MVS-8000X
only), "FC Input 13-16" (MVS-8000X only), "FC
Output 1-2," and "FC Output 3-4."
