Monitor Cabling
Monitors are supported for Analog Audio, Digital Audio, Analog Video,
and Digital Video modules. Port and Time Code modules do not have
monitor outputs. The physical configuration of the Concerto frame will
determine how many and what type of monitoring devices can be con-
nected.
Analog Video Monitoring
Analog Video modules have one backplane, use internal bussing for
monitor outputs, and cannot be combined with any other module type. All
outputs are available to all Analog Video modules in the same configured
matrix. Each backplane has a single BNC
Mon Out
, so the number of modules
in the configured matrix will determine the number of Mon Out connec-
tors. A 32x32 configured matrix will have outputs 1-32 available to a single
Mon Out
BNC connector. A 64x64 configured matrix will have outputs 1-64
available to two
Mon Out
BNC connectors. Both outputs are the same and
two monitoring devices can display the same Video signal. The
Mon In
con-
nectors are not used. For more information on configured matrix sizes and
number of
Mon Out
connectors per matrix see
Digital Video Monitoring
There are two types of Digital Video modules a SD Digital Video and a HD
Digital Video. Each of the two modules has its own BNC backplane. These
modules use external loop cabling for monitor outputs and the two types
of Digital Video can be combined into a configured matrix.
CAUTION The maximum number of HD modules that can be in a 7 RU Concerto frame
is three in which case the fourth slot has to remain empty. If two HD modules
are used then the other two slots can be loaded with any of the non HD mod-
ules.
The preferred hierarchy between 3Gb/s, SD and HD Video modules in the
same configured matrix is to place the SD modules before the HD and 3Gb/
s modules. For example, if you have a frame with two SD modules and two
HD modules, place the SD modules in slots 1 and 2, and the HD modules
in slots 3 and 4. Then all the SD video signals (outputs 1-64) will be routed
to the HD modules (outputs 65-128) making all outputs available to the
Mon
Out
BNC connector on the backplane in slot 4. HD signals (1.485 Gbps) can
only be routed through HD modules, so if the HD module is before a SD
module it will break the chain.
