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

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

. 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
