    5.6 Wireless Status Wireless status is mainly to display channel information, such as master and slave nodes, whether to synchronize, working frequency points, distance display and network data volume statistics. It also displays the status of the local device and some information about the remote device.
  • Page 21: Wireless Noise

    5.7 Wireless Noise Background noise detection is mainly used to detect ambient interference of master and slave equipment. The red line represents the bottom noise at the primary end and the blue line represents the bottom noise at the secondary end. And the lower the absolute value, the cleaner the floor noise, that is, the smaller the interference source.
