In the electronic weighing system, the requirements for the weighing display instrument are very strict. First, the stability and display accuracy/display speed are better, and the second is the humanized operation of the electronic scale instrument and the function and adaptability of the output interface. The most typical is the RS232 asynchronous serial output function. Its technology is mature and can be connected to computers, large-screen displays, printers that support RS232 serial ports, and most electronic products support RS232 interface cards. Therefore, most of the electronic weighing instrument products have increased the RS232 interface.
The higher the cost performance of the electronic scale, the more various functions it has. For example: electronic balance, which basically supports all functions; while electronic platform scales support electronic scale command output, ordinary weighing scales basically do not support RS232 function, high-precision counting scales basically support electronic scale command output, and electronic platform scales basically all Support RS232 interface output.
