Installation Instructions
Wiring & Networking
The addresses of the modules are uniformly set to No. 1 before leaving the factory. When multiple modules are used in parallel, it must be ensured that each module number (station address) on the line is different. If there are the same, the module data between the same numbers Interference will occur, so that the communication can not be normal. When multiple modules are used on one line, it is recommended to start from No. 1 and compile them in order. To change the address, please use our free software to change, before changing, please connect the module to the computer through the converter.
