Grass Valley VM 3000 System Controllers v.7.4 - Manual (Page 243)

Configurator Switcher Description Table
5−33 VM 3000 Installation and Operating Manual
This method of enforcing vertical interval switching applies only to Grass Valley switchers operating on the Crosspoint
Bus port of the VM. For “remote serial control” applications, including Triton, Horizon, TEN−20 / 20−TEN, and 3rd
party routers, VI should be unchecked on all levels.
5.
RV
Reverse switching. This item applies only to certain data switchers. For video, audio, and time code switchers,
leave unchecked.
This box is checked for older model RS−232/422/423 data switchers equipped with DM 400/400A § Data Matrix boards.
Configuration of DM 400/400A Data Matrix boards is described in Appendix L.
Newer model data switchers equipped with DM 400B § Data Matrix boards use only one level, and the “RV” box is left
unchecked (even though “reverse” switching is still taking place).
6.
MC
Select machine control assignment follow Yes or No for this level. Normally checked for video level and un-
checked for all others. One (only) level can be checked.
As explained in detail elsewhere in this manual, the usual procedure is for the machine assignment system to follow the
distribution switcher; that is, if a certain VTR is selected for a certain destination, then the associated machine control
panel will automatically assume control of that VTR. (See Assigning Machines to Control Panels on page 5−149 for more
information.) This menu item determines which level will be used as the reference in making the machine assignment.
7.
Board
Select the name of the VM/CM controlling this level.
The source of these names is the Network Description table (page 5−22).
Each logical level can be controlled by a separate VM.
Redundant VM boards, if any, are ignored on this table. Recall that redundant VM boards have the same logical name.
Using a single VM, one or more Grass Valley Crosspoint Bus routers can be connected to the Crosspoint Bus port.
Triton routers, or certain non−Crosspoint Bus routers, can be connected to a VM 3000 serial port (odd−numbered only).
SI 3000 serial ports cannot be used for this purpose.
Special entries are required in this column for Saturn Master Control Switchers equipped with an internal switching
matrix.
