2. Introduction

This chapter summarizes the Micro125 device server’s features and the basic information needed to get started.

Capabilities

The Micro125 device server has the following capabilities:
Connects devices through a TCP data channel or through a Telnet connection to
computers or to another device server. The Micro125 also supports UDP datagrams.
Contains a web [HTTP] server allowing presentation of custom content and easy
configuration through a browser.

Applications

The Micro125 device server connects serial devices such as those listed below to Ethernet networks using the IP protocol family.
ATM machines CNC controllers Data collection devices Environmental sensors Universal Power Supply (UPS) management units Telecommunications equipment Data display devices Security alarms and access control devices Handheld instruments Modems Time/attendance clocks and terminals
Micro125 User Guide 9

Protocol Support

The Micro125 device server uses the Internet Protocol (IP) for network communications. It uses the Transmission Control Protocol (TCP) to assure that no data is lost or duplicated, and that everything sent to the connection arrives correctly at the target.
Supported protocols include:
ARP, UDP, TCP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and SNMP for network
communications and management.
TCP, UDP, and Telnet for connections to the serial port. TFTP for firmware and web page updates. IP for addressing, routing, and data block handling over the network. User Datagram Protocol (UDP) for typical datagram applications in which devices interact
with other devices without m aintaining a poin t-to-point connection.

Configuration Me thods

2: Introduction
For the unit to operate correctly on a network, it must have a unique IP address on the network. There are three basic methods for logging into the device server to assign an IP address and configure the unit:
DeviceInstaller: Assign an IP address and view the current Micro125 configuration using a Graphical User Interface (GUI) on a PC attached to a network. (See Using DeviceInstaller.)
Web-Manager: Through a web interface, configure the Micro125 and its settings using the Micro125’s Web-Manager. (See Configuration Using Web Manager
Serial & Telnet Ports: There are two approaches to accessing Serial Mode. Make a Telnet connection to the network port (9999) or connect a terminal (or a PC running a terminal emulation program) to the unit’s serial port. (See Configuration via Telnet or Serial Port
(Setup Mode).)

Addresses and Port Numbers

Hardware Address

The hardware address is also referred to as the Ethernet address or the 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.
Example: 00-20-4A-14-01-18
Note: Make note of the MAC address. It is needed to locate the Micro125 using
DeviceInstaller.
Micro125 User Guide 10
2: Introduction

IP Address

Every device connected to an IP network must have a unique IP address. This address is used to reference the specific unit. The Micro125 is autom atically assigned an IP address on DHCP-enabled networks, as it is DHCP-enabled by default.

Port Numbers

Every TCP connection and every UDP datagram is defined by a destination IP address and a port number. For example, a Telnet application commonly uses port number 23. A port number is similar to an extension on a phone system.
The unit's serial channel (port) can be associated with a specific TCP/UDP port number. Port number 9999 is reserved for access to the unit's Setup (configuration) Mode wi ndo w. Ports 0­1024 are reserved as well. For more information on reserved port numbers, see Table 8-5.

3. Getting Start ed

This chapter covers the steps required to get an embedded device physically connected.

Physically Connecting the Unit

The following diagram shows a properly installed Micro125. Other devices connect in a similar manner.
Figure 3-1. Evaluation Board Connected to Serial Device and Network
1. Connect a computer or serial device to your unit.
2. Connect an Ethernet cable to the RJ-45 Eth ernet por t.
3. Supply power to your unit using the power supply that was included in the packaging.
Note: The required input voltage for the Micro125 is 5VDC (+/-5% at ~200 mA). Other
devices may require a different voltage.
4. Supply power to the serial device.

Required Information

Hardware Address

You need to know the unit’s hardware address (also known as the MAC address), which is on the product label. It is in the format: 00-20-4a-XX-XX-XX, where the XXs are unique numbers assigned to the product.
Micro125 User Guide 12
Hardware Address: 00-20-4a-_____-_____-_____
3: Getting Started

IP Address

Your device server must have a unique IP address on your network. The systems administrator generally provides the IP address and corresponding subnet mask and gateway. The IP address must be within a valid range, unique to your network, and in the same subnet as your PC.
IP Address: _______ _______ _______ _______ Subnet Mask: _______ _______ _______ _______ Gateway: _______ _______ _______ _______ You have several options for assigning an IP address to your unit. We recommend that you
manually assign the IP address over the network using DeviceInstaller software, which is described in Using DeviceInstaller.
Micro125 User Guide 13

4. Using DeviceInstaller

This chapter covers the steps for getting the Micro125 device server online and viewing its current configuration.
Note: DeviceInstaller is a free utility program provided by Lantronix that
discovers, configures, upgrades, and manages Lantronix Device Servers. It can be downloaded from the Lantronix website at
www.lantronix.com/support/downloads.
For instructions on using DeviceInstaller to configure the IP address and related settings or for more advanced features, see the
Online Help.

Installing DeviceInstaller

To install DeviceInstaller:
DeviceInstaller
1. Download the latest version of DeviceInstaller from
2. Run the executable to start the installation process.
3. Respond to the installation wizard prompts. (If prompted to select an installation type, select Typical).

Assigning an IP Address

The unit’s IP address must be configured before it can work correctly on a network. You have several options for assigning an IP to your unit. We recommend that you manually assign the IP address over the network using DeviceInstaller.
Note: To use a serial connection instead of an Ethernet connection to configure the device,
see Chapter 6: Configuration via Telnet or Serial Port (Setup Mode).
The unit’s IP address is normally set to 0.0.0.0 at the factory. The hardware address is on the product label. The unit is DHCP enabled as the default.
To assign an IP address manually:
1. Click StartAll Programs LantronixDeviceInstaller 4.3DeviceInstaller. If your PC has more than one network adapter, a message displays. Select an adapter and click OK.
Note: If the unit already has an IP address (e.g., DHCP has assigned an IP address), click
the Search icon and select the unit from the list of Lantronix device servers on the local network.
http://www.lantronix.com/downloads.
2. Click the Assign IP icon
3. If prompted, enter the hardware address (on the product label) and click Next.

5. Configuration Using Web Manager

You must configure the unit so that it can communicate on a network with your serial device. For example, you must set the way the unit will respond to serial and network traffic, how it will handle serial packets, and when to start or close a connection.
The unit’s configuration is stored in nonvolatile memory and is retained without power. You can change the configuration at any time. The unit performs a reset after you change and store the configuration.
In this chapter, we describe how to configure the Micro125 using Web-Manager, Lantronix’s browser-based configuration tool. (For information on using Setup Mode, our command line configuration interface, see Chapter 6: Configuration via Telnet or Serial Port (Setup Mode).
Note: The examples in this section show a typical device. Your device may have different
configuration options.

Accessing Web-Manager Using DeviceInstaller
