Banking Teller Networks
Quatech RS-232 serial boards are currently being used in
international banking applications to construct teller networks.
Clearly, it would not be economical for each branch of a
multinational bank to keep data for the entire organization on
their own PC. At the same time, they need instantaneous access
to that central data, so that customers can be serviced at any of
the branches. Further, not only must each branch have access
to the data, but each teller station as well. The teller also needs
to be able to print checks for customers, get account information
from a customer's bank card, and of course check balances and
credit or debit accounts.
A simple, inexpensive RS-232 serial network is ideal for connecting
multiple devices over short distances that are in turn linked with
a database which may be located on the other side of town, or
on the other side of the world.
As shown in the above diagram, the heart of the teller network is
the central computer which contains account information for all
the bank's customers. The branch computer links to the central
computer via a high-speed modem. Each individual teller has
multiple serial links to the branch computer which connect CRTs,
check printers, and bank card readers. This connection is made
through a series of RS-232 serial ports. Many of these networks
are used in OS/2 environments, because of the high stability and
reliability of that operating system. Our customers are currently
using Quatech DS-100 and DSC-100 two-port ISA and PCI cards
for this purpose. However, Quatech RS-232 cards also come in
four- and eight-port versions, all of which are supported under
OS/2, allowing more devices to be connected using a single card.
Virtual Gaming
Quatech's DSC-200/300 serial PCI board is currently being used
to implement the MultiSport Stadium interactive sports simulator.
In this virtual dream machine, players use real balls to compete
against life-size video athletes. These on-screen athletes react in
real time to the live player’s throw, pass or pitch.
The system utilizes infrared sensors to detect the trajectory
of the real ball after it has been launched by the player. This real-
time communication process is made possible by Quatech’s two
port RS-422 serial I/O board, the DSC-200/300, which allows the
PC to communicate with both pairs of Newton Lab sensors. One
of the serial ports communicates with the down-range array and
the other with the up-range array.
The computer then analyzes this information and projects a virtual
ball to continue the flight into 3-D space on-screen. At the same
time, the computer selects and runs an appropriate video script
from a library of pre-captured footage. The result is a seamless
interactive sports experience, in which the player enjoys the thrill
of playing in a pro stadium against top athletes.
