Please first confirm whether the RS485 wiring is loose, AB reverse connection and other problems, and then click the key to check the table of general parameters numbers, such as address, baud rate, check bits etc., are set correctly.
Please use the USB to 485 serial port line to connect with the instrument RS485 interface, and read the parameters in the table through communication. Verify whether the parameters in the table are the same as the wireless configuration of the upper main station (channel and spread spectrum factor). If they are different, please modify the instrument wireless parameters to be consistent with the master station and then test again; If the same, it may be the instrument and the master station. Too far apart or serious field interference, at this time can try to use an external suction cup antenna, or consider the nearby new wireless master and test again.
