RS485 over Narrowband Powerline Communication Modem (110/220V)

RS485 is widely used in electronics system. PLC-RS485 modem from LinkSprite uses LinkSprite PLC-RS485 module,and isdesigned to send/receive RS485 data over the powerline network. PLC-RS485 is designed to transparently move serial data over the powerline network.
LinkSprite modules have the built-in packet-level repeater function. This feature can greatly extend the coverage of the powerline communication.

LinkSprite modules has both physical and logic addresses. In a network, both physical and logic addresses can be used to address different nodes in the network.

  • Fully transparent mode, plug and play coming out of the box without the need to do any programming. 
  • Built-in error correction codes.
  • Built-in repeater function to extend the coverage.
  • Physical and logic address
  • AT commands used for advanced configuration.
  • RS485 interface to host uP
  • FSK(Frequency Shift Keying) modulation used in physical layer
  • Low power Design
  • RoHS
  • Small module size, and easy to be implemented into existing products.
