Operation procedure

Step 1: Connect the ranging module with data cable to supply power to the module and output measurement data; (Note: no plug and strictly control the supply voltage range at 5V); or supply power via CR2 (3V) battery;

Step 2: Install the serial port elf software and connect to a computer or other control device via the connection port.

Step 3: After the software is installed, open the display interface.

 

Commissioning and testing

Select COM port: Set the corresponding COM port in the software based on the computer's COM port.

Baud rate setting: Open the software interface to set the baud rate, with options of 38400/1920/14400/9600bps (default is 9600).
