| Abstract: | The design and realization of four channels RS422 communication card is introduced. The card can be used in high speed data communication. It allows 128 interface ICs to connect with each other on one bus, which makes it easy to use the card in multi-computer system. The implementation of communication program in windows98 is described. |
