1、中文中文 2700 字字 RS-232 Interface RS-232 is one of the normally used interfaces at any time, it not only built in every PC-set, but also built in any types of computers which are from microcontroller to host computers, and equipment connected with them. The general usage of RS-232 is to connect a modern

2、, the other arrangements with RS-232 interfaces include printer, data collection module, testing device and control loop. RS-232 can be also used in the simple link of any type of computer. RS-232 is designed to deal with the communication between two arrangements with distance limitation from 50 to

3、 100ft, which depend on Potter rate and type of electric cable. Because of wide application of RS-232 port, its other usage is to link another type of adapter converted form the port. For example, a simple loop changes a RS-232 into a RS-485 port. The port can be link with several devices by means o

4、f a long lead. Non-equilibrium lead is used to linked to RS-232. Although non-equilibrium should something avoidable, it only refers to the electric property of the signal in lead. In a non-equilibrium lead, signal voltage is applied to another lead, all has another technical term “signal end”. Adva

5、ntages in RS-232 RS-232 is used everywhere. Every PC-set has one or more RS-232 ports. The renewed computers sustain other serial interfaces like USB. But RS-232 can do many things which USB cant do. In the micro-controller interface chip can be easily used to change into RS-232. The jointing distan

6、ce can reach 50-100ft. Many external interfaces are not used for too long distance. The longest distance joint of USB can reach 16ft. The distance between parallel printer interface on the PC-set and the host computer can reach 10 to 15ft, or 30ft by using Type TEEE-1284B driver. But RS-232 can use the longer electric cable. If every RS-232 port is linked with a modern, Telephone network can used to send data in the rage of the world. For a double link, 3 leads are needed. A parallel circuit ge
