3.0 BEFORE YOU BEGIN
3.1 A BRIEF NOTE
The CM9740-CC1 is a nonexpandable CPU, optimized for systems ranging from
a 16 x 4 configuration (16 inputs and 4 outputs) to a 256 x 32 configuration (256 in-
puts and 32 outputs).
Beginner or New to 9740
If you are totally new to Pelco, or are familiar with Pelco but new to the 9740 ma-
trix system, read on.
3.2 FOR THE BEGINNER OR NEW USER,
A FEW WORDS OF ADVICE AND SOME EXERCISES
From a hardware standpoint, the CM9740-CC1 is ubiquitous to 9740 System op-
eration. Section 4.0 addresses that aspect of the CC1.
In addition to its physical prominence, the CC1 is central to the software tasks re-
quired within the 9740 System. These tasks include configuration, initialization,
and system control in operational mode.
Normally, CM9740-CC1 installations are problem free and follow an installation
scenario that proceeds as follows:
1. Everything is assembled together for the system configuration according to
the provided roadmap, which exists in the form of port assignment sheets
that tell you how everything physically relates to everything else–what device
is attached to what port, and so on.
2. After all equipment and cables are installed and everything is finally hooked
up, the power is turned on.
3. The system initializes.
Setup is complete and operation can begin. At some later point in time, however, if
the existing system configuration needs to be changed, upgraded, or downgraded,
then no matter how simple or complex your system is, there are two areas related
to system software with which one should become thoroughly familiar:
• The directory structure of the CC1.
• The administrative extension of the system executable (the MGR* program)
and the configuration files (flat files)** that comprise your specific system.
If you are not familiar with these two points, we encourage you to take the time
NOW, rather than be forced by necessity later, to become familiar with these two
items.
It’s easy. Very little equipment must be connected. Your entire system does not
have to be connected, nor does it have to be up and running to perform the two
exercises that discuss these topics. If the previous statement applies in your
case, or if you are responsible for implementing system configuration changes,
then consult Appendix VII, which guides you through the entire process.
* MGR:
The MGR program is an admin-
istrative extension of the 9740 executable.
The executable resides on the hard drive
of the CC1; the MGR program, when in
use, resides on an external PC connected
to the CC1.
** FLAT FILES:
Flat files are information
files based upon your particular system
configuration that the system executable
uses to know what it’s connected to and
how to talk to it. These flat files are created
at the factory for your particular system
configuration. For multi-node systems, a set
of configuration files is created for each
node (each node has its own CC1). The
CM9740-CC1 cannot be used to construct
multi-node systems. It can, however, ap-
pear as a node within a multi-node sys-
tem. These flat files can be found in two
different locations: (1) on the CC1 hard
drive in the C:\9740 directory and (2) on
the floppy disk labelled “Utilities.”
