          Common Question:

          1.ModbusRTU common question:

          Q ① : What is the default communication parameter for the module?
          A ① : ModbusRTU module default communication parameters are baud rate 9600, data bit 8, stop bit 1, no checksum, device default ID number is 1.
          Q ② : How to modify the communication parameters of the module?
          A ② :The use of third party software tool ModbusPoll, the control of the 3 register definition Instruction "section 40001, 40002, 40003, read three register data sequentially represents the device address, baud rate, parity check, modify according to" Instruction ", a list of parameters, communication module. After the power is restarted, the set parameters become effective.

 

 

          2.BACnet MSTP commnon question:

          Q ① : What is the default communication parameter for the module?
          A ① : BACnet MSTP module default communication parameters are baud rate 38400, data bit 8, stop bit 1, no checksum, device default ID number is 1.
          Q ② :How to modify the device number (i.e. address) of the module?
          A ②:Computer connected to the module of A, B port through the USB 485 communication lines, using BACnetScan tool from Shanghai Sunfull to scan the module point, right click your device (e.g. Device,1), select "Change Device ID", you can modify the module device number (i.e., address).
