Sub-GHz RF Mesh Single Phase Terminal Slave Module

Product ID.： WL410S/ WL411S/ WL412S

Communication mode：UART(Local), RF(Remote)

WL410S/ WL411S/ WL412S module works as DN (Distributed Node) in fast wireless data transmission Mesh network, connect and collocate with terminal devices linked to the micro-power network, and finish relay and collection of network data

  • Main Functions
  • Technical Parameters
  • Anti-interference function. Use low noise, high receiver sensitivity and advanced data encryption technology. High anti-interference function, high communication rate;
  • Binary channel, independent communication. Adopt independent communication strategies in CN and UN channels to maximize user experience;
  • Networking function. Quickly respond to mesh command from wireless communication modules. Repeat and collect data after entering into the network;
  • Wireless communication environment analysis function. Inquire RSSI of communication link between nodes through directive to check current communication quality;
  • Support user device connection. System will allocate one UN channel for user device and strengthen interaction with users;
  • Event report function. Automatically send data to CN/UN;
  • Local communication parameter self-adaptation. Support local communication baud rate and handshaking self-adaptation.
