The reference ports use BNC connectors for analog bi-level or tri-level sync
reference connection. A valid reference signal must be applied to the REF IN port
when the system is configured for external sync.

AMP to your house time clock. When recording from a satellite feed, apply frame
synchronization hardware between the receiver and the video input channel. The
synchronization hardware and the NEXIO AMP mainframe must be connected to
the house reference.
