MV-831 Monitoring Modes
When an MV-831 is fitted to a Sirius 830 router, the multiviewer block within the MV-831
module has access to the following signals:
• 24 router video outputs.
• 24 router video signals from the router’s optional second (redundant) crosspoint.
• 24 router video inputs.
See Figure 1-5.
The multiviewer block can thus access up to 3x24 = 72 signals. However, it only has 48
multiviewer inputs. A small MV crosspoint selects the 48 signals for the multiviewer.
The simplest multiviewer monitoring mode is the default monitoring mode, see MV-831
Default Monitoring Mode (24 Outputs and 24 Inputs) , on page 12.
Other signal monitoring combinations are under the control of the router configuration (see
Router Configuration Settings for Monitoring Mode , on page 13). MV-831 General Monitoring
Mode , on page 15, describes the general monitoring mode.
