Application: Public Transport Ticketing System Kiosk

Quatech Products Used: QSU-100 4 Port USB to RS-232 Serial Adapter

Public transport systems are largely turning to auto-pay and smart card solutions for their fare systems. These public transport ticketing systems are typically based on a kiosk enclosure that contains an embedded or single board PC to which a variety of peripheral devices are attached. More and more frequently the only ports available on these embedded PCs are USB ports, yet a large percentage of the peripheral devices used in these systems are only available with a serial interface, or are far more economically purchased with a serial interface. Quatech USB serial adapters are the perfect solution for these systems because they provide up to 8 standard serial ports via a single USB port, and at the same time they enhance the functionality of the serial devices themselves, for example by providing faster data rates.

Quatech USB serial adapters are currently being used in public transportation fare systems throughout the world. The above application drawing depicts a typical system in which Quatech's QSU-100, a 4 port RS-232 to USB serial adapter is connected via USB to the embedded PC in the Kiosk. The 4 serial ports are attached to the systems 4 RS-232 peripheral devices--a cash slot, a coin slot, a keypad, and a ticket printer/dispenser.
