Glossary−2 CM 4000 Installation and Operating Manual
binary super crosspoint bus - similar to super crosspoint bus, but the units digits are allowed to cover the range
of 0 to F, rather than 0−9 as in previous switcher systems. Generated only by the Jupiter,
CE-2500, and BCS 3000
control systems.
breakaway − independent operation of a switcher level. Same as “split.” Contrasts with normal
AFV operation.
Example: selecting video from VTR1 but audio from Announce Booth 2.
BTS − Broadcast Television Systems. A joint venture of Bosch and Philips. Now part of Grass Valley.
bus − in distribution switching, a channel leading to an output or destination. Example: “controls 20 buses” means
being able to select sources for 20 destinations.
button−per−input/output control panel − buttons are dedicated to a particular source or destination. As
opposed to
CATEGORY/NUMBER control.
category/number selection method − operator first picks category (example: VTR); then unit within category.
CE 3000 − Matrix Controller. Interface between
LAN and CROSSPOINT BUS. Now obsolete.
chop − rapid, back−and−forth switching between two inputs.
CM 4000 − hardware platform developed as follow−on to
VM 3000.
configuration set − a file server directory containing files that are downloaded to CONTROLLER BOARDS. These
files are used to establish network addresses, switcher input and output names, types of VTRs in system, etc.
controller board − (1) term used for the interface unit between Jupiter
LAN and the RS−422 bus. Includes VM 3000
Control Processor, SI 3000 Control Processor, and VG 3000 Video Display/Status Generator. Also refers to
BCS 3000 boards: SC 3000 Serial Control Interface, CE 3000 Matrix Control, and PL 3000
PARTY LINE Inter-
face. In
ESBUS terminology, each of these boards functions as a coupler, gateway, and bus controller. (2) Con-
certo router controller module such as the CRS−MC−C2.
CP 3200 − a Jupiter GUI control panel associated with
JNIA. Superceded by the JNS Software Control Panel Suite.
CP 3300 − an X−Y panel, developed by Philips
BTS in Germany, with soft keys displaying configured names. The
hardware contains 2 lines of 20 characters and displays four character and eight character source and destina-
tion names.
CP 3310 − an X−Y panel similar to the CP 3300 that can display status for either five or eight outputs.
CP 3320 − a control panel developed by the Grass Valley Systems group in Germany.
CP board − control panel for Saturn Master Control switcher.
CPL − Control Point Language. Protocol used in SMS7000 Control System.
crosspoint − distribution switcher circuit where input signal can be connected to output bus. A 10 x 10 crosspoint
board has 100 crosspoints.
