Dimensions(mm) & Wiring Guidance & Adjustment Methods

RS485 cascade wiring method

The computer's built-in serial port is usually RS232, which requires a 232-485 converter (active and isolated converters are recommended for industrial environments). After conversion, RS485 is divided into two wires, A and B. A is connected to the A terminal on the board, and B is connected to the B terminal on the board. The 485 shield can be connected to GND. If there are many devices, it is recommended to use twisted shielded cables and a chain network structure.
