DATA TRANSMITTING SYSTEM AND THE TRANSMITTING METHOD

摘要

The present invention relates to a data transmission system and a method thereof to form a high-frequency electron beam and to communicate with multiple devices with different communication standards. The system according to the present invention comprises: a control computer which transmits and receives data or control signals including channel numbers through a single transfer bus; one or more data transmitters which is connected to the single transfer bus, is operated by channel number, and converts the method of the control signals and data to transmit and receive; and one or more external devices which is connected to the data transmitter and receives control signals or transmits data. The data transmission system is very cost-effective because the external devices which have RS232C interfaces with different control commands, baud rates, and communication standards are controlled by a single RS422 interface, eliminating the need of multiple communication lines in the control computer.
