Quatech USB 2.0 serial adapters are reliable solutions for a wide variety of commercial uses in industries such as banking, retail, hospitality and industrial automation. Boasting speeds of up to 921 kbps, the new Quatech USB 2.0 serial adapters enumerate themselves as standard serial ports without changes to application software or hardware.
The Quatech USB 2.0 serial adapters connect a single USB port to one, two, four or eight devices with RS-232, RS-422 or RS-485 serial ports. The 100 Series are RS-232 only while the MEI (multi-electronic interface) 400 Series are software-selectable between RS-232/422/485.
To achieve the 921 kbps data rate the USB to serial adapters use high speed UARTs with 1024 FIFOs to buffer the data. Quatech USB serial adapters offer full modem control and hardware/software flow control and are bus powered (no external power supply needed). All Quatech USB 2.0 serial adapters are now RoHS compliant, adhering to the recent European Union policy banning lead and other hazardous substances.
Optional industrial surge suppression is available to safeguard the USB serial adapters from potentially harsh industrial environments. Embedded, board-only units are also available, allowing OEM customers to seamlessly integrate Quatech USB to serial products into customised equipment.
With the trend towards PCs that have only USB expansion options, the Quatech USB 2.0 serial adapters provide the ideal solution for connecting multiple serial devices to a system.
