Application: Banking Teller Station
Quatech Products Used: DSC-100 two port RS-232 Serial PCI Board or DSCLP-100 two port RS-232 Serial Universal Low Profile PCI Board

Quatech serial boards are currently being used in a majority of the bank teller stations being installed today. One such implementation, where our two port serial boards are used in combination with the computers native serial ports is described below. An interesting note about this project with a major US bank is the the two form factor implementation. The project started with Quatech PCI boards being used with full size IBM NetVista A40 series PCs. As the bank began implementing more systems, they also began using IBM NetVista M42 PCs. The NetVista M42 cannot use a standard PCI board, it requires a LowProfile PCI boards such as Quatech's DSCLP-100. Because Quatech drivers for the PCI and LowProfile Universal PCI boards are identical, the bank was able to stage and implement both systems identically, as far as setting up application software was concerned.

The Quatech driver support for these cards was crucial in the bank's decision to implement using our boards instead of another vendor's less expensive boards. We were the only ones offering OS/2 support for both standard and low profile serial boards. And, now that the bank is migrating their systems to Windows XP, they are staying with Quatech even though our products cost them more--because they realize that in the end Quatech's commitment to quality design and manufacturing, and our commitment to on-time delivery and customer service, results in fewer returns, fewer board failures (.018% failure rate!) and fewer service calls which over time more than covers the additional upfront cost of Quatech boards.

Bank teller stations must do more than simply access customer data. Each teller station must be equipped with a number of peripheral devices in order to process a wide variety of transactions. Quatech serial boards are used to expand a teller-station PC beyond the two native serial ports on the motherboard.

In this particular application, each teller station is equipped with a card swiper, a key pad, a pen pad and a cash drawer. Two of the devices are connected via native RS-232 ports, and the other two via a Quatech two port RS-232 serial board. The diagram on the left uses Quatech's DSCLP-100 Low Profile Universal PCI board and the one on the right our DSC-100 two port PCI serial board. Both boards use the same driver, enabling them to both function identically with the bank's application software.

Application: Banking Teller Networks
Quatech Products Used: QSCLP-100 four port RS-232 Serial Universal Low Profile PCI Board

A typical bank teller station has several peripherals such as CRTs, cash drawers, card readers, check printers, and keypads. Bank systems have historically used a standard serial interface to connect these peripherals to the host PC. New systems are implemented using a thin client PC. Low Profile PCI boards are small enough to fit these downsized systems, and robust enough to encompass an entire teller station with a single card.

Application: ATM
Quatech Products Used: QSCLP-100 four port RS-232 Serial Universal Low Profile PCI Board

ATMs are based on a PC embedded at the center of the machine. This PC connects to multiple serial peripherals such as keypads, cameras, printers, cash dispensers, card readers, touch screens, etc., as required by the particular application. This serial connection is made via multiport serial cards or adapters which can provide up to 16 ports each. Low Profile PCI boards are a particularly good choice for these applications, because their small size is advantageous to the often limited space available in a typical ATM. The diagram below depicts an ATM implemented with Quatech's QSCLP-100 four port RS-232 Serial Universal PCI Low Profile Board.
