ABB 1SBP260020R1001 07CR41在嵌入式系统的开发和应用中，经常需要使用上位机实现系统的调试及现场数据的采集和控制。一般是通过上位机本身配置的串行口，通过串行通讯技术和嵌入式系统进行连接通讯。串行口的典型代表是RS-232-C及其兼容插口，25针串行口还具有20mA电流环接口功能，用9、11、18、25针来实现。

USB全称Universal Serial Bus(通用串行总线)。USB接口是现在比较流行的接口，用于将使用USB的外围设备连接到主机。USB大的好处在于能支持多达127个外设，并且可以立供电。普通的串、并口外设都要额外的供电电源，而USB接口可以从主机上获得500mA的电流，并且支持热拔插，真正做到即插即用。

ABB 1SBP260020R1001 07CR41红外线通讯是一种廉价、近距离、无连线、低功耗和保密性较强的通讯方案，在PC机中主要应用在无线数据传输方面，但目前已经逐渐开始在无线网络接入和近距离遥控家电方面得到应用。鉴于红外线通讯的诸多好处，现在的主板几乎全部提供了红外线接口，以便用户利用它进行与带红外线接口的设备通讯，如笔记本电脑、打印机、Modem、掌上电脑、移动电话等等。但计算机主板上仅仅提供了红外线接口，并未提供完整的发射接收装置，所以用户在想使用红外线通讯时，仍然需要购买红外线连接器。

ABB 1SBP260020R1001 07CR41 In the development and application of embedded systems, it is often necessary to use the host computer to realize system debugging and field data collection and control. It is usually connected with embedded system by serial communication technology through serial port configured by host computer itself. The typical serial port is RS-232-C and its compatible jack, and the 25-pin serial port also has a 20mA current loop interface function, which is realized with 9, 11, 18, and 25 pins.

The full name of USB is Universal Serial Bus. The USB interface is now a popular interface for connecting peripheral devices that use USB to the host computer. The big benefit of USB is that it can support up to 127 peripherals and can be powered immediately. Ordinary series and parallel port peripherals need additional power supply, and the USB interface can obtain 500mA of current from the host, and supports hot swap, truly plug and play.

ABB 1SBP260020R1001 07CR41 Infrared communication is a cheap, close range, no connection, low power consumption and strong security communication solution, mainly used in PC wireless data transmission, but has gradually begun to be used in wireless network access and close remote control of home appliances. In view of the many benefits of infrared communication, almost all the motherboards now provide infrared interfaces, so that users can use it to communicate with devices with infrared interfaces, such as laptops, printers, modems, handheld computers, mobile phones and so on. However, the computer motherboard only provides an infrared interface, and does not provide a complete transmitting and receiving device, so users still need to buy infrared connectors when they want to use infrared communication.
