Monitoring Signals with MV-841/851 in Sirius 840/850
A simplified diagram of a Sirius router is given in Figure 3. Routed video signals from the router
crosspoint are presented as router outputs via the output modules.
The multiviewer monitoring capabilities of an MV-841/851 for single and expanded Sirius
router frame systems are described in the following sub-sections.
Single-frame Sirius 840/850 Systems
When an MV-841/851 is fitted to a Sirius 840/850 router, the user can use the multiviewer for
monitoring router outputs (destinations) and/or monitoring router inputs (sources)
in any
combination.
Figure 4. show an example use case with a combination of router output and
input monitoring.
1152 x 1152 Expansion Sirius 850 Systems
In a Sirius 850 router expansion system, one or more MV-851 multiviewers can be fitted and the
user can use the multiviewer to monitor the (larger, expanded) router, monitoring router
outputs (destinations) and/or monitoring router inputs (sources)
in any combination.
