4. Overview of Supported Commands and Their Significance
To modify the baud rate, the transmitter will acknowledge by sending back the baud rate provided by the host. Once acknowledged, the transmitter's baud rate will seamlessly transition to the new specified value.
When changing the address, the transmitter will first respond with the current address. Following this acknowledgement, the transmitter will automatically update to the new address value.
Issuing the save and reply factory command will return the original data value, confirming that the transmitter has successfully accepted the host's command.
Please note, when restoring factory settings, the pre-saved factory parameters may differ from user-specific settings. Therefore, the address, baud rate, and calibration data may change. Ensure to re-scan the transmitter after restoring factory defaults.
Users are permitted to modify only three specific data points: address, baud rate, and zero offset.
For calibration or adjusting calibration data, please contact our company to obtain the transmitter's calibration software. Unauthorized command modifications by the user will result in a command exception code from the transmitter. Only use our provided calibration software for such operations.
When reading data identified as a floating point number, such as 6.000, note that the protocol communicates this data as integer values. For example, 6000 is read instead of 6.000, and to convert, divide by 10 raised to the decimal places, e.g., 6000/10^3 yields 6.000.
