178 Concerto — Installation and Service Manual
Glossary
J Number
Jack Number.
Jumper
A short conductor used to manually bridge
two contact points. Used in Series 7000
Alarm system. Also called a strap.
Kadenza
A Grass Valley Group digital video effects
system.
Kaleidoscope
A Grass Valley Group digital video effects
system.
KISS
Key Input Source Select. Used in configuring
the Kscope Key Sources.
KScope
The collective name for Kadenza and Kalei-
doscope.
Krystal
A Grass Valley Group digital video effects
system.
LED
Light emitting Diode. In Grass Valley prod-
ucts, LEDs illuminate to indicate a specific
state (such as normal, error, on-line, and so
on).
Local
Local is used during configuration to identi-
fy local Sources and Destinations. Local
Sources and Destinations are inputs and out-
puts physically connected to the System us-
ing the related configuration file.
Master
A module that controls a subordinate (slave)
module.
Matrices
Plural of matrix.
Matrix
A configuration of potentially intersecting
inputs and outputs. In routing switchers, sig-
nal switching hardware configured such that
any input may be switched to any output.
MC
Matrix Controller.
MEC
Matrix Element Control. The MEC bus con-
nects the control circuits of the various ma-
trix modules in a frame section to the Node
Controller. In some cases, when the MCPU
and Node Controller reside in the same
frame, these connections are all internal to
the frame. More often, there are multiple
Node Controllers in a system and a coaxial
cable is run between Node Bus ports of each
frame in the system. Only secondary systems
and a particular compact configuration run
external MEC buses.
MEDIC
Matrix Element Decode Integrated Circuit.
Used as a communications bus between the
MCPU and Controllers.
Mezzanine
A secondary printed circuit module consist-
ing of a flat circuit board of insulating mate-
rial with conductive circuits etched on and/
or components mounted on its surface.
These sub-modules generally plug into a pri-
mary module. Sometimes referred to as a
submodule or daughter board.
Module
A single circuit board or assembly of circuit
boards that can be readily removed from an
electronics frame without first having to re-
move screws or other mounting hardware.
