Serial Data Cables
The RS-422 cables used to connect CM-4000 or CM-4400 System Controllers
and control panels consist of a 4-conductor (plus ground) cable. Maximum
length per bus, at 115k Baud, is 610 meters (2000 ft.).
The rear panel serial data cable connectors on the CM-4000 or CM-4400 and
control panels are 9-pin D, female. The control panel connectors are
arranged for loop-through wiring. No termination is required. While these
connectors are ESbus compatible, it should be noted that the Grass Valley
serial data cables use only 5 of the 9 pins described in the ESbus specifica-
tion.
The following ready-made cables, with installed 9-pin D male connectors,
are available from Grass Valley (VDE cables include ferrite cores):
For those who wish to prepare their own cables, the pin-outs are shown in
Figure 5 . The cable itself should be Belden 8723 or equivalent.
Details concerning ferrite cores are given in Figure 6 on page 30 .
