CC-2010 Matrix (Crosspoint Bus) Cable
Connection from a Jupiter VM-3000 or CM-4000 System Controller is
via a crosspoint bus cable, which can be supplied in 3, 10, 25, or 50 foot
lengths. The crosspoint bus connector is looped out in order to connect
the bus to the next item under crosspoint control.
Depending on the size of the switcher this bus may require interme-
diate buffering through a CB-3000 Control Buffer. A CB 3000 is required
in the following cases:
DV-33128 - eight or more chassis
DV-33256 - four or more chassis
DV-33512 - two or more chassis
The CB-3000 is described in detail in the Jupiter Installation and Oper-
ating manual.
In Trinix applications, the crosspoint bus must be terminated at the
point farthest from the control processor using a Crosspoint Bus Termi-
nator, part number 01-053050-001.
The CC-2010 is a 10-conductor (plus ground) cable. Ready-made cables,
with installed 15-pin D male connectors, are available from Grass
Valley; see page 88.
All rear-panel crosspoint bus connectors are 15-pin D, female.
For those who wish to prepare their own cables, pin-outs are shown on
page 150. The cable itself should be Belden 9505 or equivalent. User-
supplied matrix cables for VDE installations require a ferrite core over
each end of the cable, adjacent to the connector. Details concerning
ferrite cores are given on page 150.
