GRASS VALLEY CROSSPOINT BUS ROUTERS
The VM 3000 can be used to control Apex, Trinix, Concerto, and other routers listed in Figure 2−3.
— For conventional (square matrix) switchers (such as Apex, Trinix, and Concerto), only one VM 3000 will typi-
cally be required (or two for redundancy purposes), since a single unit is capable of controlling up to 1024
video or audio outputs in each of 96 logical levels.
§
For a redundant installation, see page 2−4.
— If the switcher is of the three−stage type, multiple VM 3000s may be needed. Please refer to Appendix H after
reviewing this section.
The various switchers listed below can be mixed on the same Grass Valley Crosspoint Bus; however, the VM 3000 drives
the matrix according to “super” Crosspoint Bus rules.
Note: A majority of TVS/TAS 2000 model switchers presently in the field will require updated crosspoint board
state PROMs in order to accept super Crosspoint Bus signals. Older units in the 2000 series may also require audio
crosspoint board modifications in order for the correct PROMs to be installed.
The VM 3000 must be configured using the Network Description table (page 5−22) and the Switcher Description table (page
5−31).

However, the practical number of levels that can be controlled depends on the total number of outputs. For more informa-
