MAX3082 RS232 to RS485 Conversion

1. Description 1. Serial port UART, baud rate: 9600 When connecting a device, generally only GND RX TX is connected, and Vcc is not connected to avoid power supply conflicts with the target device. 1.1 RS485 standard (+2V ~ +6V: 1 / -6V ~ -2V: 0) 1.2 RS232 standard (-15V ~ -3V: 1 / +3V ~ +15V: 0), MAX232 needs

　　1 Problem Statement 　　One of the more commonly used networks in the field of industrial control and measurement is the industrial control equipment network composed of the RS-485 communication interface at the physical layer. This communication interface can easily form a control network with many devices. From th
