Support the Modbus RTU protocol, which can quickly connect to controllers that support this protocol for fast I/O port expansion. Please refer to the instructions for the Modbus RTU protocol debugging tool for specific usage methods.

 Support the BACnet MSTP protocol, which can quickly connect to controllers that support this protocol for fast I/O port expansion. Please refer to the BACnet MSTP protocol debugging tool instructions for specific usage methods.

Q: What are the default communication parameters for the module?

Answer: The default communication parameters for the ModbusRTU module at the factory are baud rate 9600, data bit 8, stop bit 1, no verification, and the device default ID number is 1.

Q: How to modify the communication parameters of the module?

Answer: Using the third-party tool ModbusPoll software, refer to the "3.0 Register Definition Description" section to read the data of the 40002 and 40003 registers, representing the communication baud rate and verification. According to the description in the "Description" column, modify the communication parameters of the module. After power outage and restart, the set parameters take effect.

Q: How can I modify the device ID?

Answer: Move the internal paddles.
