You can now broaden the range of external peripherals used on your computer at higher speed rates, with High Speed USB 2.0 Serial Adapters. The USB 2.0 has more bandwidth that allows higher data rates on the serial ports and improved system efficiency.
The new High Speed USB Serial Adapter line gives your laptop or workstation the ability to communicate between a USB port and up to eight RS- 232, RS-422, or RS-485 serial peripherals. It adds the COM port(s) via its USB connection and is compatible with new and legacy RS-232 or RS- 232/422/485 devices. The USB Serial Adapters are the ideal solution for a variety of industries and applications including banking, retail and industrial automation where PCs have a significantly shorter lifecycle than the peripherals that use them.
Quatech QSU2-100IND Four port USB to RS-232 Serial adapters with Surge Suppression are being used as part of a real-time reaction analysis system. The system is designed to both identify reactants, products and intermediates in a chemical reaction and to track the course of the reaction with a single automated system. The system is comprised of four reactors, each of which can be individually controlled and conditioned, with a probe integrated into the base of each. Modulated infrared radiation is passed to each of the reactors in turn, and a spectrum is measured and passed to a Windows NT-based PC via a surge protected serial to USB interface. Up to thirty spectra per hour are obtained from each reactor and used by the system to derive concentration profiles. This application was originally implemented with standard USB to serial adapters, however results were unpredictable and inaccurate. After much testing, our customer found that the added protection of Quatech's "IND" surge suppression package was the only USB to Serial solution that would work in their systems.
