3.3 Bridge Card
(Redundant Versions: A94x.037035 and up, see
chapters 3.3.1.1
and
3.3.1.2
)
The SCore Bridge card is used in the SCore Live to manage the whole core
system. Two Gigabit Ethernet connectors provide a redundant connection
to the desk or host application. The card downloads code to the DSP cards
and passes serial data, parameters, and meter data between the desk or host
application and the DSP cards. Furthermore, a sub-circuit is acting as a master
clock generator for the system. It can accept video, WCLK and AES inputs
from the External Sync card, and generates a local clock from these. The
implementation has been made in such a way that a change from internal to
external sync or vice versa causes no audible artifacts, and the DSP cards will
continue processing.
In a Vista system, the SCore Live runs with the last setting within less than
10 seconds after powering up thanks to a non-volatile memory (gold cap
backup, capacity sufficient for approx. one week).
Two
bridge cards may be
plugged into the frame for redundant operation (A94x.037035 and up). The
inactive bridge card will not be connected to the system buses and remains
in idle mode. The card is hot-pluggable.

SCORE LIVE BRIDGE CARD A943.0370
IMPORTANT
Although the bridge card hardware is identical for OnAir 3000/Route 6000
and Vista systems, the firmware is different.
A Vista bridge card cannot be
used for an OnAir 3000 or Route 6000 system, and vice versa.
When removing or inserting a bridge card from/into the frame, proceed very
carefully. The bottom side of the cards hosts some capacitors that are pretty
large. If the card is not inserted exactly aligned with its guides, these capaci-
tors may catch at the panel left of the bridge card’s slot, causing one of these
capacitors to snap off when sliding the card in or out too fast.
