Overview

The Mport3101 series provide data transmission between Ethernet and a serial port (RS-232/RS-485/RS422). These units may be used in pairs to provide the straightforward transmission of a serial interface across an IP network. They may also be used individually to communicate with remote hosts using standard protocols.

Setup is very simple using the web browser interface. Advanced features include a MODBUS gateway and watchdog timers. An AC adapter is provided, or the unit may be powered via a wide ranging DC power input.

Technical Notes

Modbus Notes

Modbus TCP / RTU integration

Since its inception in 1979 Modbus has become a widely used communication protocol in the field of industrial automation. Originally based on serial interfaces (RS232 and RS485) Modbus RTU enjoys widespread use throughout many different industries. Since then Ethernet has become the network of choice and many industrial devices now have native Ethernet interfaces.

Quick Start Guides

Mport - Quickest way to connect 2 serial devices over Ethernet

The Mport range of serial devices servers have a mode of operation that allows very quick provisioning of 2 units to create a serial tunnel over an Ethernet network.

This 'Pair Connection Mode' is easy to setup.

On one Mport configure its mode of operation to be 'Pair Connection Master'
