7500 Series Instruction Manual
MCO
Machine Control Only Control Panel.
MCPU
Master Control Processing Unit. This mod-
ule provides:
• Overall system control
• Node manager interface to Series 7000
matrices
• Direct control panel support for up to 64
control panels
• Programmable real-time clock, date and
time stamping for logged events
• Redundant controller interface (allows
primary and backup MCPU pairs)
• Static RAM sizes (ranging from 128k bytes
to 4M bytes) are supported
• Flash ROM sizes (ranging from 128k bytes
to 4M bytes) are supported
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 submodules 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.
Multiformat
Ability to pass multiple signal types, such as
serial digital, analog component, and analog
composite.
Name(s)
Sources, Destinations, Levels, Salvos, Con-
trol Panels, Node Controllers, MCPUs, Mez-
zanine Boards, Tally Modules, and other
components of the Series 7000 system all
have names. When system software sets out
to perform a function, a Take for instance, it
looks for the source name, determines the in-
puts involved, and Takes the Source to the
Destination specified (by name). Naming
conventions are discussed in Section 1 of the
Configuration manual. Names are important
to operation and equally so to configuration.
NB (Node Bus)
Node Bus. A name for the communications
bus between the MCPU and Controllers.
NB (Narrow Band)
Identifies the 7500 Series AES Audio Matri-
ces.
