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.

u盤驅動程序 通用串行總線(USB Universal Serial Bus)是一種計算機與外部設備連接的新技術,相對于PC傳統(tǒng)的串/并行接口,USB具有較高的數(shù)據(jù)傳輸率、即插即用、熱插拔、易擴充和低成本等優(yōu)點。從USB標準頒布以來的短時間內,USB已成為PC必備的標準接口。

通用串行總線USB(Universal Serial Bus)是一種新型的微機總線接口規(guī)范。隨著客戶對系統(tǒng)數(shù)據(jù)采集速度要求的不斷提高,USB以其使用方便、易于擴展、速度快等優(yōu)點而越來越多的應用于數(shù)據(jù)采集系統(tǒng)中。本文介紹了一種基于USB總線的數(shù)據(jù)采集系統(tǒng)的設計方法,采用PHILIPS公司的USB接口芯片PDIUSBD12與單片機AT89C51進行通信,并和PC機通信而編制出友善的設備應用程序。該系統(tǒng)用傳統(tǒng)的USB總線取代了RS232串行總線,通過對USB協(xié)議和設備構架的充分理解,對以單片機89C51和USB接口芯片PDIUSBD12為主的數(shù)據(jù)采集系統(tǒng)進行了硬件設計和軟件編程,并在此設計的基礎上給出相應的原理圖。硬件設計主要解決的是PDIUSBD12和ADC0809與單片機之
