Control Systems
Depending on the size of the Routing switcher, this bus may require inter-
mediate buffering through a CB-3000 Control Buffer. A CB 3000 is required
in the following cases:
•
TRX-NXT-128x128 - eight or more frames
•
TRX-NXT-256x256 - four or more frames
•
TRX-NXT-512x512 - two or more frames
•
TRX-NXT-128x256 - four or more frames
•
TRX-NXT-256x512 -two or more frames
•
TRX-NXT-256x512 -more than one frame
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.
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.
All rear-panel Crosspoint bus connectors are 15-pin D, female.
For those who wish to prepare their own cables, pin-outs are shown in
. The cable itself should be Belden 9505 or equiva-
lent. 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
