Public Transport Ticketing Systems
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.
