Introduction
This device can be set paring in one master to multiple slaves.It can transmit data by Transparent or Modbus protocol but it’s better to use Modbus because of semi-duplex transmission.This device suitable to collect data from long range, wide area under small packet and loose data transmission requirement.We don’t recommend it for real time control.
