Keywords USB DataA cquisition Adttc831 PDfUSBD12 Windriver0 引言US B总 线 是新一代接口总线,最初推出的目的是为了统一取代PC机的各类外设接口,迄今经历了1.0,1.1与2.0版本3个标准。在国内基于USB总线的相关设计与开发也得到了快速的发展,很多设计者从各自的应用领域,用不同方案设计出了相应的装置[1,2]。数据采集是工业控制中一个普遍而重要的环节,因此开发基于USB接口的数据采集模块具有很强的现实应用意义。虽然 US B总线标准已经发展到2.0版本,但由于工业控制现场干扰信号的情况比较复杂,高速数据传输的可靠性不容易被保证,并且很多场合对数据采集的实时性要求并不高,开发2.0标准产品的成本又较1.1标准产品高,所以笔者认为,在工业控制领域,目前开发基于USB总线1.1标准实现的数据采集模块的实用意义大于相应2.0标准模块。

The PL2303 USB to Serial adapter is your smart and convenient accessory forconnecting RS-232 serial devices to your USB-equipped Windows host computer. Itprovides a bridge connection with a standard DB 9-pin male serial port connector inone end and a standard Type-A USB plug connector on the other end. You simplyattach the serial device onto the serial port of the cable and plug the USB connectorinto your PC USB port. It allows a simple and easy way of adding serial connectionsto your PC without having to go thru inserting a serial card and traditional portconfiguration.This USB to Serial adapter is ideal for connecting modems, cellular phones, PDAs,digital cameras, card readers and other serial devices to your computer. It providesserial connections up to 1Mbps of data transfer rate. And since USB does not requireany IRQ resource, more devices can be attached to the system without the previoushassles of device and resource conflicts.Finally, the PL-2303 USB to Serial adapter is a fully USB Specification compliantdevice and therefore supports advanced power management such as suspend andresume operations as well as remote wakeup. The PL-2303 USB Serial cable adapteris designed to work on all Windows operating systems.
