User manual QUATECH USB 2.0 INDUSTRIAL DATASHEET

[. . . ] High Speed Industrial USB Serial Adapters Add standard serial ports via USB 2. 0 without replacing peripheral hardware or application software For over 20 years, Quatech has been known to help you Connect with Reliability. As we continue as an industry leader an objective to meet our customers requirements, our high performance device connectivity line expands to offer hardened industrial products. [. . . ] While the units are bus powered, a DC voltage power input is avaialble via terminal blocks to provide power output in RS-232 mode on pin 9 to power external serial devices. LEDs indicators for power, USB ready and data (transmit and receive per port) give visual indication of proper function. KEY FEATURES 4 Independent Serial Ports RS-232 or RS-232/422/485 MEI with Terminal Block Connectors Compatible with USB 2. 0/ USB 1. 1 Plug-and-play capability Devices enumerate themselves as standard COM ports Speeds up to 921. 6 kbps High speed UARTs with 1KB FIFOs to boost data rates Full modem control and hardware and software flow control Bus powered: no external power required, External power input available by terminal block to provide optional VDC out on Pin 9 in RS-232 operation Windows 2000/XP/Vista/Windows 7, Linux RoHS compliant NEW!U3000 V DC to DC Optical Isolation available (QSU2-540IS) LED Indicators (Power, USB Ready, Data Transmit and Recieve per Port) 1 year warrantynty Connect Industrial serial peripherals with Ruggedized USB 2. 0 Serial Multiport Adapters If speed, expansion, reliability and support are what you're looking for in a USB Serial Adapter to handle harsh conditions and environments, think Quatech Industrial USB 2. 0 to Serial adapters. With Quatech's USB 2. 0 based adapters, you can now broaden the range of external peripherals used on your computer at higher speed rates . The USB 2. 0 has more bandwidth that allows higher data rates on all of the serial ports for more efficiency. The new High Speed USB Serial Adapter line adds the COM port(s) via its USB connection and is compatible with new and legacy RS-232 or RS232/422/485 devices. The Industrial USB Serial Adapters are the ideal solution for a variety of applications including industrial automation / control, material handling / logistics and laboratory test and measurement in addition to other demanding applications where a robust and ruggedized solution is required.

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 7 based PC via a serial to USB interface. Up to thirty spectra per hour are obtained from each reactor and used by the system to derive concentration profiles. [. . . ] Each master radio requires a dedicated serial port on the polling computer, and Quatech's QSU2-540IS provides the additional serial ports required.
