EDS4100 Overview
2: Introduction
The EDS4100 is a compact device
Figure 2-1 EDS4100 4 Port Device Server
server that allows you to networkenable asynchronous RS-232 and
RS-422/485 serial devices. It can
deliver fully transparent RS-232/422
point-to-point connections and RS485 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.
Key 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 software
AES, SSH, or SSL secure data encryption
Three configuration methods (Web, command line, and XML)
Print server functionality (LPR/LPD)
See Chapter 3: Installation of EDS4100 for installation instructions.
EDS Device Server User Guide 17
EDS8PR, EDS16PR, and EDS32PR Overview
The EDS8PR (8 serial ports), EDS16PR (16 serial ports), and EDS32PR (32 serial ports) are
compact easy-to-use, rack-mountable device servers that give you the ability to network-enable
asynchronous RS-232 serial devices. They provide fully transparent RS-232 point-to-point
connections without requiring modifications to existing software or hardware components in your
application.

Evolution OS™ Application
The EDS device server incorporates the Lantronix Evolution operating system (OS). Key features
of the Evolution OS include:
Built-in Web server for configuration and troubleshooting from Web-based browsers
CLI configurability
SNMP management
XML data transport and configurability
Really Simple Syndication (RSS) information feeds
Enterprise-grade security with SSL and SSH
Comprehensive troubleshooting tools
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.
2: Introduction
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 interface. 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 uses industry-standard tools for
configuration, communication, and control. For example, the Evolution OS software uses a
Command Line Interface (CLI) whose syntax is very similar to that used by data center equipment
such as routers and hubs.
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 devices.
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.
EDS Device Server User Guide 20
2: Introduction
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 software 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.
With built-in SSH and SSL, secure communications can be established between the serial ports
and the remote end device or application. By protecting the privacy of serial data transmitted
across public networks, users can maintain their existing investment in serial technology, while
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.
EDS Device Server User Guide 21
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 Chapter 5: Using DeviceInstaller.
2: Introduction
Web Manager: Through a web browser, configure the EDS settings using the Lantronix Web
Manager. See Chapter 6: Configuration Using Web Manager.
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 appropriate EDS Device Server Command Reference for instructions and
available commands. Lantronix documentation is available at
www.lantronix.com/support/documentation
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 appropriate EDS Device Server Command Reference for instructions and
available commands. Lantronix documentation is available at
www.lantronix.com/support/documentation
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 as either 00-20-4A or 08-04-13, identifying the
