MV-841/851 and Sirius Router Frame
Router Frame Requirements
The MV-841/851 Integrated Multiviewer option consists of some hardware modules fitted into
front and rear slots of a Sirius 840/850 router frame. The MV-841/851 Multiviewer modules may
be purchased already fitted into a new Sirius 840/850 router from Grass Valley or bought
separately as a hardware upgrade option, to be fitted to an existing Sirius 840/850 router.
One or more MV-841/851’s may be fitted to a router.
MV-841/851 router frame requirements are:
•
Sufficient router power supply capacity: Contact Grass Valley for advice.
•
2-off adjacent front output module slots.
•
+ 2-off corresponding rear module slots.
, on page 29, shows which Sirius router slots are used for the MV-841/851.
When fitting the MV-841/851 into an existing router, the relevant router slots may already be
used by other Sirius 800 modules and, in this case, those modules need to be removed as part
of the MV-841/851 installation (see
Sirius 800 User Manual
). If in doubt, do contact Grass Valley
Support, see
Grass Valley Technical Support
Additionally, the fitting of one or more MV-841/851 modules into a Sirius router frame affects
the frame’s operating temperature range. See
Integration into Sirius 840/850 Routers
The MV-841/851 Multiviewer modules are double-width modules. A MV-841/851 fits into a
pair
of vertical output front and rear module slots (i.e. 2 front slots and 2 rear slots) in a Sirius 840/
850 router frame, see Figure 2. The MV-841/851 module looks like a pair of Sirius standard
video output modules to the Sirius router controller system.
More than one MV-841/851 may be fitted into a Sirius 840 or Sirius 850 router.
The MV-841/851 Integrated Multiviewer combines the functionality of:
• 2-off Sirius 840/850 standard router video HD-BNC output cards (expandable)
+
• 1-off Powerful 48-input multiviewer.
