Installation Instructions

When adjusting the baud rate, the transmitter will respond with the baud rate provided by the host. After this confirmation, the transmitter's baud rate will seamlessly switch to the newly set value, ensuring optimized performance.
Upon altering the address, the transmitter will acknowledge by sending back the current address. After this exchange, the transmitter will automatically update to the new address, ensuring continued precision and reliability.
Executing the save and reply factory command will revert to the original settings, signifying that the transmitter has successfully accepted and implemented the host's command.
When reloading factory data, please be aware that the factory-set parameters might differ from user-saved settings. This discrepancy may affect the address, baud rate, and calibration data, necessitating a re-scan of the transmitter post-restoration for optimal operation.
Users are permitted to modify only three specific data points: address, baud rate, and zero offset. Adhering to these parameters ensures stable and accurate device functionality.
For calibration or changes in calibration data, please contact our company to obtain the necessary calibration software. User attempts to alter calibration data directly may trigger a command exception code from the transmitter. Utilize our proprietary software for all calibration modifications to ensure accuracy and integrity.
When reading data identified as a floating point number, such as 6.000, but communicated as an integer by protocol, the data is represented as 6000. To convert, apply the predetermined decimal point value. For instance, if the decimal is 3, dividing 6000 by 10^3 yields 6.000, maintaining data precision and consistency.
