2. Overview

2.1 Introduction

The 1-Port Modbus Hardened Serial Server connects Modbus networks (RS-232, RS-422, or RS-485) to Ethernet networks, allowing the Modbus network to become a node on the network. The serial port can be accessed over a LAN/WAN using Direct IP Mode connections. Modbus Hardened Serial Servers use 10BASE-T or 100BASE-TX copper network media. The servers are built for use in industrial environments and feature an IP30 approved slim-line DIN-rail-mountable case. The product operates from a range of DC power supply voltages and features pluggable terminal block power connectors. The Modbus Hardened Serial Server has one Ethernet port.
