SGW1-IA2-MMP  Modbus Multiplexer

SGW1-IA2-MMP Modbus Multiplexer

Quick Overview

The SGW1-IA2-MMP Modbus Multiplexer is capable of connecting up to 3 Modbus ASCII/RTU masters to single Modbus ASCII/RTU slaves transparently. The multiplexer buffers the masters polls giving them priorities, depending which of them came first, and then sends them to the slaves. The unit has four independant serial ports that can be connected to a Master or Slave unit with different baud rates, Modbus protocols (ASCII or RTU) and serial interfaces (RS232 or RS485). The four independantly configurable serial ports also allows the SGW1-IA2-MMP to be used as a converter for RS232 to RS485 and/or from Modbus ASCII to Modbus RTU.
