Bus Linking Rules and Restrictions
• The Switched Preview, Primary Preview, and Image Store input buses cannot be
configured as Linked buses.
• An Aux bus associated with a DPM cannot be configured as a Controlling bus. However,
these buses may be configured as Linked buses.
• Once the Bus Linking associations have been established and are enabled, selecting a
source on a Controlling bus that is associated with a source on a Linked bus will make
the Linked bus select its associated source.
Special operating rules:
• Source Override—Holding down a source select button on a Linked bus prevents that
bus from changing its sources when Controlling bus source selections change.
• Bus Pair Rules—GV Switcher source selection buses can operate in pairs. M/E keyer
buses operate in video fill/key cut mode. Aux buses can be configured in pairs, either as
video fill/key cut or as video/video for external DPMs.
When a bus pair is involved in bus linking, the following rules apply:
• Key cut selections on video fill/key cut bus pairs does not affect the key cut source on a
linked bus (split key cut selections don’t link).
• The fill/A side of the Controlling bus is always sent to the fill/A side of the Linked bus.
• If t
he Controlling bus is in video/video mode, the B side selection will be sent to the
Linked bus.
