Product Overview:
 WJ157
 The WJ157 product realizes signal acquisition between sensors and hosts, used to decode encoder signals. The
 WJ157 series products can be applied in RS-485 bus industrial automation control systems, automated machine tools,
 industrial robots, three coordinate positioning systems, displacement measurement, stroke measurement, angle
 measurement, speed measurement, flow measurement, product counting, and more.
 The product includes signal acquisition, pulse signal capture, signal conversion, and RS-485 serial communication.
 Each serial port can connect up to 255 WJ157 series modules, and the communication method adopts ASCII code
 communication protocol or MODBUS RTU communication protocol. The baud rate can be set by code and can be hung
 on the same RS-485 bus as control modules from other manufacturers, making it easy for computer programming
