MCU and PC machines generally use serial communication RS-232, RS-422 or the B3-485 standard interface bus, also have the use of non-standard current loop 20nnJL. To ensure reliable communications, the choice of interface is important to note: (1) communication rate (2) Communication distance: (3) anti-jamming capability (4)组网方式. This paper mainly introduces the use of RS-232 communication interface with the single-chip approach
