Chapter 2: Overview

2. Overview

2.1 Introduction

The 1-, 2-, and 4-Port Hardened Serial Servers connect serial devices (RS-232, RS-422, or RS-485) to Ethernet networks, allowing the serial device to become a node on the network. The serial ports can be accessed over a LAN/WAN using Direct IP Mode, Virtual COM Port, or Paired Mode connections. Hardened Serial Servers use 10BASE-T or 100BASE-TX copper network media. All models also have an additional copper Ethernet pass-through port. Hardened Serial Servers are built for use in industrial environments and feature heavy duty metal enclosures that are panel- and DIN-rail mountable. The product operates from a range of DC power supply voltages and features pluggable terminal block power connectors. The LES424A also has a locking barrel connector that facilitates redundant power sources.
