General
This DLP provides a brief introduction to the PC. It includes proper handling and
storage of diskettes and some of the important procedures you should follow when
working with your PC. This DLP is a brief review of PC concepts. Refer to your PC
user's guide for a complete description.
Anatomy of a PC
PCs vary in physical appearance and size, most IBM
three basic parts — a main unit, a monitor, and a keyboard. Note that some PCs,
particularly portables, integrate the keyboard, monitor, and main unit into a
briefcase-size package. The DDM-2000 generic program may be installed with either
a desktop PC or a portable PC. The diskettes may be either 3-½ inch floppy disks or
5-¼ inch floppy disks.
Main Unit
The main unit of the PC contains the CPU (central processing unit), disk drive(s), and
memory, among other things. All main units have some common features which
include:
• ON/OFF Switch — This switch is used to switch the PC ON or OFF. It is usually
located on the back of the PC, near where the AC power cord plugs in to the PC.
• Serial Port — This is the port which the PC uses to communicate with the
customer equipment. When using the PC to install a new generic program to
DDM-2000, the COM1 port must be used. Refer to your PC documentation to
determine which port is the COM1 port. There are two types of serial port
connectors:
— 25-pin RS-232 connector (male)
— 9-pin connector (male).
