Country: United States
Overall benefits: Streamlined process, Increased
efficiency
Conventional Numerical Controllers (NC) use a process
defined by instructions typed on cards that are read
sequentially by an external card reader. However, the
process is not very flexible—when the manufacturing
process changes, an entirely new set of cards must be
created. The control process can be input from tapes,
but since the tape reader is slow, some manual opera-
tions are required. This kind of setup is not suitable
when multiple NCs operate concurrently.
To create a fully automated system, the modern NC is
equipped with a computer communication interface
(normally a serial port) that makes Computerized Nu-
merical Controllers (CNCs) easy to use. A PC running
Windows 2000, and with a MOXA C320Turbo/PCI
installed can be used. Not only can the C320Turbo/PCI
control up to 32 CNC machines at the same time via
a high-speed communication interface (460.8 Kbps
max.), it can also transmit large amounts of CAD/CAM
data to 32 CNC machines simultaneously. C320Turbo/
PCI is expandable, allowing external serial modules to
be located as far as 100 m from the host.

Country: China
Overall benefits: Improve customer satisfaction
The 1990’s saw a big increase in the number of
motorbikes and automobiles in China, leading to the
need for more gas stations to provide service and
fuel. However, most gas stations in China still use
yesterday’s management methods, and consequently
fall far short of the more stringent demands of
today’s fast-paced customers.
The key to modernizing gas stations in China is the
installation of smart gas pumps. In addition to the
usual hose and nozel, modern pumps feature an
LED display screen, a touch pad for entering data, a
creadit card reader, and a built-in computer. Moxa’s
multiport serial boards are used to connect the
touch pad, LED screen, card reader, and flow-rate
sensors to the computer. Customers are happy since
they spend less time waiting in line and get better
service from the gas station attendants. Petroleum
companies are also happy, since using credit cards
gives them a straightforward way to keep track of
and analyze their customers’ buying behavior.
