	2: Introduction
EDS4100 Overview
The EDS4100 is a compact device	Figure 2-2 EDS4100 4 Port Device Server
server that allows you to network-
enable asynchronous RS-232 and
RS-422/485 serial devices. It can
deliver fully transparent RS-232/
422 point-to-point connections and
RS-485 multi-drop connections
without requiring modifications to
existing software or hardware in
your application.
 Ports 1 through 4 support
RS-232 devices.
 Ports 1 and 3 also support
RS-422/485.

Note: RS-485 circuits support 32 full-load devices or 128 quarter-load devices. Each RS-485 port, however, counts as one device, leaving up to 31 full-load or 127 quarter-load devices that can be connected to the RS-485 circuit.

The EDS4100 device server supports the Power-over-Ethernet (PoE) standard. With PoE, power is supplied to the EDS over the Ethernet cable, by either an Ethernet switch or a midspan device. Being able to draw power through the Ethernet cable eliminates power supply and cord clutter. It also allows the EDS to be located in areas where power is not typically available.

Features

The key features of the EDS4100 include:

Dual-purpose Ethernet terminal server and device server design.

Four serial ports with hardware handshaking signals.

RS-232 and RS-422/485.

One RJ45 Ethernet port.

IEEE 802.3af standard for Power-over-Ethernet (PoE).

8 MB Flash memory.

32 MB Random Access Memory (RAM).

Lantronix Evolution OS™.

AES, SSH, or SSL secure data encryption.

Three configuration methods (Web, command line, and XML).

Print server functionality (LPR/LPD).

2: Introduction

Additional Features

Modem Emulation

In modem emulation mode, the EDS can replace dial-up modems. The unit accepts modem AT commands on the serial port, and then establishes a network connection to the end device, leveraging network connections and bandwidth to eliminate dedicated modems and phone lines.

Web-Based Configuration and Troubleshooting

Built upon Internet-based standards, the EDS enables you to configure, manage, and troubleshoot through a browser-based interface accessible anytime from anywhere. All configuration and troubleshooting options are launched from a web in terface. You can access all functions via a Web browser, for remote access. As a result, you decrease downtime (using the troubleshooting tools) and implement configuration changes (using the configuration tools).

Command-Line Interface (CLI)

Making the edge-to-enterprise vision a reality, the EDS with the Evolution OS™ uses industrystandard tools for configuration, communication, and control. For example, the Evolution OS™ uses a Command Line Interface (CLI) whose syntax is very similar to that used by data center equipment such as routers and hubs.

VIP Access

Virtual IP Access is the Lantronix technology that solves the access-through-firewall problem. With VIP Access, the EDS can act as a ManageLinx DSC and provide direct access to your equipment behind a firewall.

SNMP Management

The EDS supports full SNMP management, making it ideal for applications where device management and monitoring are critical. These features allow networks with SNMP capabilities to correctly diagnose and monitor EDS.

XML-Based Architecture and Device Control

XML is a fundamental building block for the future growth of M2M networks. The EDS supports XML-based configuration setup records that make device configuration transparent to users and administrators. The XML is easily editable with a standard text or XML editor.

Really Simple Syndication (RSS)

The EDS supports Really Simple Syndication (RSS) for streaming and managing on-line content. RSS feeds all the configuration changes that occur on the device. An RSS aggregator then reads (polls) the feed. More powerful than simple email alerts, RSS uses XML as an underlying Web page transport and adds intelligence to the networked device, while not taxing already overloaded email systems.

Enterprise-Grade Security

Evolution OS™ provides the EDS the highest level of networking security possible. This ‘data center grade’ protection ensures that each device on the M2M network carries the same level of security as traditional IT networking equipment in the corporate data center.

2: Introduction

By protecting the privacy of serial data transmitted across public networks, users can maintain their existing investment in serial technology, wh ile taking advantage of the highest data-protection levels possible.

SSH and SSL are able to do the following:

Verify the data received came from the proper source

Validate that the data transferred from the source over the network has not changed when it arrives at its destination (shared secret and hashing)

Encrypt data to protect it from prying eyes and nefarious individuals

Provide the ability to run popular M2M protocols over a secure SSH or SSL connection

In addition to keeping data safe and accessible, the EDS has robust defenses to hostile Internet attacks such as denial of service (DoS), which can be used to take down the network. Moreover, the EDS cannot be used to bring down other devices on the network.

You can use the EDS with the Lantronix Secure Com Port Redirector (SCPR) to encrypt COM port-based communications between PCs and virtually any electronic device. SCPR is a Windows application that creates a secure communications path over a network between the computer and serial-based devices that are traditionally controlled via a COM port. With SCPR installed at each computer, computers that were formerly “hard-wired” by serial cabling for security purposes or to accommodate applications that only understood serial data can instead communicate over an Ethernet network or the Internet.

Terminal Server/Device Management

Remote offices can have routers, PBXs, servers and other networking equipment that require remote management from the corporate facility. The EDS easily attaches to the serial ports on a server, Private Branch Exchange (PBX), or other networking equipment to deliver central, remote monitoring and management capability.

Troubleshooting Capabilities

The EDS offers a comprehensive diagnostic toolset that lets you troubleshoot problems quickly and easily. Available from the Web Manager, CLI, and XML interfaces, the diagnostic tools let you:

View critical hardware, memory, MIB-II, buffer pool, and IP socket information.

Perform ping and traceroute operations.

Conduct forward or backup DNS lookup operations.

View all processes currently running on the EDS, including CPU utilization and total stack space available.

Configuration Methods

After installation, the EDS requires configuration. For the unit to operate correctly on a network, it must have a unique IP address on the network. There are four basic methods for logging into the EDS and assigning IP addresses and other configurable settings:

DeviceInstaller: Configure the IP address and related settings and view current settings on the using a Graphical User Interface (GUI) on a PC attached to a network. See Using DeviceInstaller (on page 41).

EDS User Guide

22

2: Introduction

Web Manager: Through a web browser, configure the EDS settings using the Lantronix Web Manager. See Configuration Using Web Manager (on page 43).

Command Mode: There are two methods for accessing Command Mode (CLI): making a Telnet connection or connecting a terminal (or a PC running a terminal emulation program) to the unit’s serial port. (See the EDS Command Reference Guide for instructions and available commands.)

XML: The EDS supports XML-based configuration and setup records that make device configuration transparent to users and administrators. XML is easily editable with a standard text or XML editor. (See the EDS Command Reference Guide for instructions and commands.)

Addresses and Port Numbers

Hardware Address

The hardware address is also referred to as the Ethernet address or MAC address. The first three bytes of the Ethernet address are fixed and read 00-20-4A, identifying the unit as a Lantronix product. The fourth, fifth, and sixth bytes are unique numbers assigned to each unit.

Figure 2-4 Sample Hardware Address

00-20-4A-14-01-18 or 00:20:4A:14:01:18

IP Address

Every device connected to an IP network must have a unique IP address. This address references the specific unit.

Port Numbers

Every TCP connection and every UDP datagram is defined by a destination and source IP address, and a destination and source port number. For example, a Telnet server commonly uses port number 23.

The following is a list of the default server port numbers running on the EDS:

TCP Port 22: SSH Server (Command Mode configuration)

TCP Port 23: Telnet Server (Command Mode configuration)

TCP Port 80: HTTP (Web Manager configuration)

TCP Port 443: HTTPS (Web Manager configuration)

UDP Port 161: SNMP

TCP Port 21: FTP

UDP Port 69: TFTP
