The command said to a module issued a directive to the new address of the module is set to 01 and the setting can be lost to save power; the default module address is 01, when the need for networking a plurality of modules, the address of each module are set separately, because use the mailing, so setting requirements 485 network can only have a module, otherwise it will cause all the modules of 485 network address are set to the same address, please use caution the instruction; when the module receives the correct command, according to the order made corresponding action and response instruction is sent back to the host, said communication success
