1.

Install the CC-2010 Matrix (crosspoint bus) cable.
Interconnection from a Jupiter VM-3000 or CM-4000 control board

is via crosspoint bus cable, which can be supplied in 3, 10, 25, or 50

foot lengths. The crosspoint bus (“XPT BUS”) connector (15-pin D-

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

Operating manual.
In Trinix applications, the crosspoint bus must be terminated at the

point farthest from the control processor using a Crosspoint Bus

Terminator, 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 specific wiring instructions concerning CC-2010 Crosspoint Bus

Cables, please refer to the installation diagrams supplied with your

switcher.
For those who wish to prepare their own cables, pin-outs are shown

in

Figure 81 on page 150

. The cable itself should be Belden 9505 or

equivalent. Details concerning ferrite cores are given in

Figure 82
