Sync Redundant
Note This switch may be labelled “VIT Redundant” on some units.
If the system is equipped with a secondary NR-33000 board, closing
this switch will provide continued operation in case of a single NR
failure. However, operating in the redundant mode will limit the
number of possible sync sources to two. In DV-33512 systems, if Sync
Redundant mode is selected the “C” switch must also be closed. For
more information, see page 111 and page 115.
Internal Xpt (Crosspoint) Control
Open = Trinix crosspoint bus is controlled by an external crosspoint bus
controller (e.g., a Jupiter VM-3000 or CM-4000; or, an NR board in
another frame).
Closed = Trinix crosspoint bus is controlled by an internal crosspoint
controller (i.e., an NR-33000 Sync/NIC/OPM board). This setting is
used when the NR is in turn being controlled through a LAN connec-
tion to a control system such as a Grass Valley Series 7000 Signal Man-
agement System or Encore.
For more information, see page 148 and page 153
60 Hz Enable Switch
This switch is reserved for future use.
A B C Switches
The “A” switch is reserved for future use.
The “B” switch is closed in output-monitor-expanded systems where
output monitor signals are brought through a combiner. See page 144.
The “C” switch must be closed in DV-33512 systems whenever the Sync
Redundant switch is closed. This will prevent use of any sync reference
connected to the SR-33500 Sync/OPM board.
