Installation Instructions

To modify the baud rate, the transmitter will first acknowledge the baud rate value sent by the host. Once the acknowledgment is complete, the transmitter will seamlessly transition to the newly specified baud rate.
Upon modifying the address, the transmitter will initially respond with its current address. After this acknowledgment, the transmitter will automatically update to the new address.
Issuing the save and reply factory command will return the original value, confirming the transmitter's acceptance of the host's command.
Please be aware, when restoring factory settings, that factory-saved parameters may differ from user-saved ones. Therefore, the address, baud rate, and calibration data might change. It is necessary to search the transmitter anew after restoring factory settings.
Users are permitted to modify only three parameters: address, baud rate, and zero offset.
For calibration or modification of calibration data, please contact our company to obtain the necessary calibration software for the transmitter. Sending commands to modify calibration data directly may cause the transmitter to output an exception code. Use our provided calibration software for these modifications.
When the data to be read is a floating point number, such as 6.000, but the protocol specifies communication as integer data, it will be read as 6000. The decimal point is then used to compute 6.000. For example, with a decimal point of 3, 6000 divided by 10^3 results in 6.000.
