6.6.4 dual Merger Card
(
)
A949.0440
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 Vista or OnAir 3000 consoles) and the
HOST
connector of the card. In
certain SCore applications the host port is connected internally through the
backplane. The non-host ports may be used to connect other local I/O frames.
OnAir 3000 desk modules connected to the RJ45 connectors may be supplied
by the card (24 V; 20 W total per Dual Merger card), can be activated with a
DIP switch.
