 Product Overview:
 Figure 1 Appearance of WJ152 module
 The WJ152 product implements signal acquisition between sensors and hosts for measuring PWM signals. The
 WJ152 series products can be applied in RS-485 bus industrial automation control systems, automated machine tools,
 industrial robots, three coordinate positioning systems, PWM measurement, servo measurement, 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 WJ152 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.
