6.6.2 Serial Merger Card ( ) 1.949.438
This card is used to feed any Studer-internal control signals into the hub I/O
frame. A serial connection is made between the Studer product (such as a
Vista or OnAir 3000 console) and the MASTER connector of the card.
In case of an OnAir 3000 console, the SLAVE connector may be used to
connect a second local I/O frame.
In Vista 5 applications where the card is installed in the core frame, the host
port must be accessed through the front-panel MASTER connector instead
of from the backplane; this selection is done with a DIP switch that has been
added in versions 1.949.438.22 and up.
