2: Introduction
This chapter introduces the Lantronix EDS family of device servers. It provides an
overview of the products, lists their key features, and describes the applications for which
they are suited.
EDS device servers contain all the components necessary to deliver full network
connectivity to virtually any kind of serial device, a reliable TCP/IP protocol stack, and a
variety of remote management capabilities. They boast an innovative design and run on
Lantronix’s leading-edge Evolution OS™.
EDS4100 Overview
The EDS4100 is a compact, easy-to-use device server that gives you the ability 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 components in your
application.
Note: RS-485 circuits support 32 full-load devices or 128 quarter-load devices.
Each EDS4100 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.
Ports 1 through 4 support RS-232 devices.
Ports 1 and 3 also support RS-422/485 devices.

EDS Device Servers User Guide 14
2: Introduction
Web-Based Configuration and Troubleshooting
Built upon popular Internet-based standards, the EDS enables users to configure,
manage, and troubleshoot efficiently through a simplified browser-based interface that
can be accessed anytime from anywhere. All configuration and troubleshooting options
are launched from a well-organized, multi-page interface. Users can access all
functionality via a Web browser, allowing them flexibility and remote access. As a result,
users can enjoy the twin advantages of decreased downtime (based on the
troubleshooting tools) and the ability to implement configuration changes easily (based
on the configuration tools).
In addition, users can load their own Web pages onto the EDS to facilitate monitoring and
control of their own serial devices that are attached to the EDS.
Command-Line Interface (CLI)
Making the edge-to-enterprise vision a reality, the EDS with the Evolution OS™ uses
industry-standard tools for configuration, communication, and control. For example, the
Evolution OS™ uses a Cisco
similar to that used by data center equipment such as routers and hubs.
®
-like command line interface (CLI) whose syntax is very
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 device servers.
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 makes device configuration
transparent to users and administrators. The XML is easily editable with a standard text
or XML editor.
Rich Site Summary (RSS)
The EDS supports Rich Site Summary (RSS), a rapidly emerging technology for
streaming and managing on-line content. RSS feeds all the configuration changes that
occur on the device. The feed is then read (polled) by an RSS aggregator. 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
Without the need to disable any features or functionality, the Evolution OS™ provides the
EDS the highest level of 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 EDS
serial ports and the remote end device or application. By protecting the privacy of serial
data being transmitted across public networks, users can maintain their existing
EDS Device Servers User Guide 15
2: Introduction
investment in serial technology, while taking advantage of the highest data-protection
levels possible.
SSH and SSL can:
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 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 can not be used to bring down other devices on the network.
The EDS can be used with Lantronix’s 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.
The EDS also supports a variety of popular cipher technologies including:
Advanced Encryption Standard (AES)
Triple Data Encryption Standard (3DES)
RC4
Hashing algorithms such as Secure Hash Algorithm (SHA-1) and MD5
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.
EDS Device Servers User Guide 16
Applications
EDS device servers deliver simple, reliable, and cost-effective network connectivity for all
your serial devices and address the growing need to connect individual devices to the
network over industry-standard Ethernet connections. The EDS is ideal for a variety of
applications, including:
Building automation/security
Industrial automation
Medical/healthcare
Retail automation/point-of-sale
Console management
Traffic management
Building Automation/Security
Automating, managing, and controlling many different aspects of a building is possible
with the EDS. It can overcome the hurdle of stand-alone networks or individual control
systems that are not able to communicate with each other, and not able to share vital
data, in a cost effective way.
2: Introduction
The EDS can also be used to centrally manage equipment and devices over a new or
existing Ethernet network to improve the safety and comfort of building occupants, while
lowering heating, ventilating, air conditioning (HVAC), lighting, and overall energy
operating costs through centralized management and monitoring.
Industrial Automation
Today’s manufacturing facilities face the common challenges of productivity
improvements, inventory management, and quality control. From warehouse to
automotive environments, the need to attach the following devices, whether new or
legacy, continues to grow:
Programmable Logic Controllers (PLCs), Computer Numeric Control and Direct
Numeric Control (CNC/DNC) equipment, process and quality-control equipment
Pump controllers
Bar-code readers and scanners, operator displays, scales, and weighing stations
Printers, machine-vision systems, and other types of manufacturing equipment
The EDS is well suited to deliver network connectivity to all of these devices.
Medical/Healthcare
Hospitals, clinics, and laboratories face rapidly growing needs to deliver medical
information accurately, quickly, and easily, whether at bedside, the nurse’s station, or
anywhere in the facility. The goal to improve healthcare services, however, is balanced
with the need to keep the bottom line from exceeding already constrained budgets.
The EDS can network enable medical equipment and devices using the hospital’s
existing Ethernet network to improve patient care and slash operating costs. This allows
EDS Device Servers User Guide 17
2: Introduction
medical staff members to easily monitor and control equipment over the network, whether
it is located at the point of care, in a laboratory, or somewhere else in the building, all
resulting in improved quality of service and reduced operational costs.
Retail Automation/Point-of-Sale
Having the right solution in the store to manage deliveries, track orders, and keep pricing
current are all improvements that the EDS can offer to make retail operations more
successful. From big to small, one store to thousands of outlets, the EDS can empower
point-of-sale (POS) devices to share information across the network effectively.
With the EDS, retailers can increase and streamline productivity quickly and easily by
network-enabling serial devices like card swipe readers, bar-code scanners, scales, cash
registers, and receipt printers.
Console 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.
Traffic Management
With the ubiquity of Ethernet networks, managing cities over Ethernet is now within
reach. The EDS provides an easy conversion from serial ports on traffic cameras,
billboards, and traffic lights to Ethernet. The EDS obviates the need for long-haul
modems and enables the management of traffic equipment over the network.

not.
Displays the subnet mask specifying the network
segment on which the EDS resides.
Displays the IP address of the router of this
network. There is no default.
Displays the number of ports on this EDS.
Using the CLI through a SSH/Telnet session or an EDS8/16/32PR serial port.
Using the XML interface
These unified configuration methods provide access to all features, giving you the same
level of control over the EDS8/16/32PR regardless of the configuration method you
choose.
Configuring from the Web Manager Interface
With this method, you can use a Web browser to configure the EDS using a Web-based
graphical point-and-click interface. The advantages to this method are ease of use and
location independence. With this method, you can configure the EDS from any location
that has access to a Web browser and the Internet.
Configuring via an SSH/Telnet Session or Serial Port Using the
CLI
The EDS provides a command-line interface (CLI) designed to enable the configuration
and systems management functions that can also be performed through the Web
Manager and XML interfaces. To configure the EDS using the CLI, you must either start
an SSH or Telnet session or use a terminal or a computer attached to one of the EDS
serial ports or the console port on the EDS8/16/32PR.
The difference between the SSH/Telnet and serial interfaces is the physical connection
paths to the EDS. With an SSH/Telnet session, you can configure the unit without having
to be in the same location as the EDS. The serial-interface method, however, requires a
terminal or computer to be attached to an available EDS serial port. This means the
terminal or computer must be in the same location as the EDS.
For more information, see the EDS Command Reference on the product CD or the
Lantronix web site (www.lantronix.com
).
EDS Device Servers User Guide 32
5: Getting Started
Configuring from the XML Interface
The EDS also provides an XML interface that can be used to perform configuration and
systems-management functions. This configuration method lets you automate the
configuration process using XML configuration files. This method is particularly
convenient if you have multiple EDS device servers that will use the same configuration
settings, because you can define a configuration profile that can be imported by, and
shared among, your other EDS device servers.
For more information, see the EDS Command Reference on the product CD or the
Lantronix web site (www.lantronix.com
).

Log Format Enter the format of the HTTP log. The log format directives are as
follows:
%a remote IP address (could be a proxy)
%b bytes sent excluding headers
%B bytes sent excluding headers (0 = '-')
%h remote host (same as '%a')
%{h}i header contents from request (h = header string)
%m request method
%p ephemeral local port value used for request
%q query string (prepend with '?' or empty '-')
%t timestamp HH:MM:SS (same as Apache '%(%H:%M:%S)t' or
'%(%T)t')

%U URL path info
%r first line of request (same as '%m %U%q <version>')
%s return status
The maximum length for each directive is 64 bytes. The exception is
'%r' where each element is limited to 64 bytes (i.e. method, URL
path info, and query string). The default log format string is: %h %t
"%r" %s %B "%{Referer}i" "%{User-Agent}i"
HTTP Authentication Page
HTTP Authentication allows you to require usernames and passwords to access specific
web pages or directories on the EDS's built-in web server.
For example, to add web pages to the EDS to control or monitor of a device attached to a
port on the EDS, you can specify the user and password that can access that web page.
If you click Authentication at the top of one of the HTTP pages, the HTTP Authentication
page displays. Here you can change HTTP authentication settings.
Under Current Configuration, URI and Users have a Delete link. If you click Delete, a
message asks whether you are sure you want to delete this information. Click OK to
proceed or Cancel to cancel the operation.
Example:
The following example shows how to add authentication to user-loaded web pages in a
directory called port1control.
1. Create a directory called port1control in the EDS's files system (using an FTP client,
Windows Explorer, or the EDS Web Manager).
2. Copy the custom web pages to this directory.
EDS Device Servers User Guide 79
8: Services Settings
3. On the HTTP Authentication page of the EDS Web Manager, add:
A URI of port1control
A Realm of Monitor
An AuthType of Digest
A Username and Password
4. Click the Submit button. The EDS creates a username and password to allow the
user to access all web pages located in the directory port1control in the EDS file
system.
Note: The URI, realm, username, and password are user-specified, freeform
fields. The URI must match the directory created on the EDS file system. The
URI and realm used in the example above are only examples and would typically
be different as specified by the user.

Authentication
Page Settings
URI Enter the Uniform Resource Identifier (URI) of the resource that will
participate in the authentication process. Default is /.
Realm Enter the domain, or realm, used for HTTP operations. Default is
<config>.
AuthType Select an authorization type. Different types of authorization offer
varying levels of security. Choices are (from least to most secure):
None = no authentication necessary.
Basic = encodes passwords using Base64.
Digest = encodes passwords using MD5. (Default)
SSL = page can only be accessed over SSL (no password).
SSL/Basic = page can only be accessed over SSL (encodes
passwords using Base64).
SSL/Digest = page can only be accessed over SSL (encodes
passwords using MD5).
SSL alone does not require a password, but all data transferred to and
from the HTTP Server is encrypted. There is no reason to create an
authentication directive using None, unless you want to override a
parent directive that uses some other AuthType. Multiple users can be
configured within a single authentication directive.
Username Enter the name of the user who will participate in the authentication.
Default is admin.
Password Enter the password that will be associated with the username. Default
is PASS.

RSS Feed Select whether an RSS feed is enabled or disabled. An RSS
syndication feed is served by the HTTP server. This feed contains
up-to-date information about configuration changes that occur on
the EDS. Choices are:
On = RSS feed is enabled.
Off = RSS feed is disabled. (default)
Persistent Select whether the RSS feed is persistent. Choices are:
On = data is stored on the filesystem, in the file “/cfg_log.txt.” This
allows feed data to be available across reboots or until the factory
defaults are set.
Off = data is not stored on the filesystem. (default)
Max Entries Enter the maximum number of log entries. The RSS feed is a
scrolling feed, with only the last Max Entries entries cached and
viewable. To be notified automatically about any configuration
changes that occur, register the RSS feed within your favorite RSS
aggregator. Default is 100.
Each RSS feed entry is prefixed with a timestamp
"[BC:HH:MM:SS]". BC is the Boot Cycle value and indicates the
number of times the EDS has rebooted since factory defaults were
last loaded. The resulting "HH:MM:SS" is the time since the EDS
booted.
