TAILIEUCHUNG - Serial Communication EIA RS232, RS422 and RS485

Serial Communication EIA RS232, RS422 and RS485 Recommended Standard 232. The purpose of this course note is to attempt to describe the main elements in Serial Communication. This application note attempts to cover enough technical details of RS232, RS422 and RS485. EIA - Electroonic Industries Associatio. Characteristics of Communication Systems Must be a Sender and Receiver A protocol is a set of rules which governs the transfer of data between computers. Protocols allow communication between computers and networks. Handshaking is used to establish which protocols to use. Handshaking controls the flow of data between computers Protocols will determine the speed of transmission,. | Serial Communication EIA RS232 RS422 and RS485 Recommended Standard 232 The purpose of this course note is to attempt to describe the main elements in Serial Communication.

EIA - Electroonic Industries Association 1 Characteristics of Communication Systems à- Must be a Sender and Receiver à- A protocol is a set of rules which governs the transfer of data between computers. Protocols allow communication between computers and networks. Handshaking is used to establish which protocols to use. Handshaking controls the flow of data between computers Protocols will determine the speed of transmission error checking method size of bytes and whether synchronous or asynchronous Examples of protocols are RS-232 TCP IP . 5 Basic Components Every communication system has 5 basic requirements Data Source where the data originates Transmitter device used to transmit data Transmission Medium cables or non cable Receiver device used to receive data Destination where the data will be placed
