2. Introduction
This chapter summarizes the xPico device server’s features and the basic
information needed to get started.
Capabilities
The xPico 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 xPico also supports UDP datagrams.
Contains a web [HTTP] server allowing presentation of custom content and easy
configuration through a browser.
Has eight programmable I/O pins used to monitor or control attached devices.
Applications
The xPico 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
xPico User Guide 11

2: Introduction
Protocol Support
The xPico 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, TCP/IP, UDP/IP, BOOTP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and
SNMP for network communications and management.
TCP/IP, UDP/IP, 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 maintaining a point-to-point connection.
Configuration Methods
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 xPico configuration using
a Graphical User Interface (GUI) on a PC attached to a network. (See 3 Using
DeviceInstaller.)
Web-Manager: Through a web interface, configure the xPico and its settings using
the xPico’s Web-Manager. (See 4Configuration 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 5 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 identify the unit as a Lantronix
product. The fourth, fifth, and sixth bytes are unique numbers assigned to each unit.
Example: 00-80-A3-14-01-18
Note: Make note of the MAC address. It is needed to locate the xPico using
DeviceInstaller.
xPico User Guide 12

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 xPico is automatically 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 window. Ports 0-1024 are reserved as well. For more information on reserved
port numbers, see to Table 7-4. Reserved Port Numbers on page 42.
Product Information Label
The product information label on the unit contains the following information about the
specific unit:
Part Number
Revision
Manufacturing Date Code
Product Model
Country of Origin
Lantronix Datamatrix Barcode
MAC Address

3. Using DeviceInstaller
This chapter covers the steps for getting the xPico 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 DeviceInstaller
Online Help.
Installing DeviceInstaller
To install DeviceInstaller:
1. Download the latest version of DeviceInstaller from
http://www.lantronix.com/downloads.
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 5Configuration via Telnet or Serial Port (Setup Mode) on page 35.
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 StartPrograms LantronixDeviceInstallerDeviceInstaller. 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.
xPico User Guide 14

3: Using DeviceInstaller
2. Click the Assign IP icon .
3. If prompted, enter the hardware address (on the product label) and click Next.
4. Select Assign a specific IP address and click Next.
5. Enter the IP address. The Subnet mask displays automatically based on the IP
address; if desired, you may change it. On a local network, you can leave the
Default gateway blank (all zeros). Click Next.
6. Click the Assign button and wait several seconds until a confirmation message
displays. Click Finish.
7. Select the device from the main window list and select Ping from the Tools
menu. The Ping Device dialog box shows the IP address of the selected unit.
8. From the Tools menu, click the Ping button. The results display in the Status
window. Click the Clear Status button to clear the window so you can ping the
device again.
Note: If you do not receive “Reply” messages, make sure the unit is properly
attached to the network and that the IP address assigned is valid for the particular
network segment you are working with. If you are not sure, check with your systems
administrator.
9. Click the Close button to close the dialog box and return to the main window.

4. 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 xPico using Web-Manager,
Lantronix’s browser-based configuration tool. (For information on using Setup Mode,
our command line configuration interface, see 5 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
Note: For more information on DeviceInstaller, see 3 Using DeviceInstaller.
1. Run DeviceInstaller and search for the list of available Lantronix device servers.
2. Click on the xPico folder. The list of available xPicos displays.
3. Expand the list of xPicos by clicking the +symbol next to the xPico icon.
4. Select the xPico unit by clicking its hardware address.
5. In the right pane, click the Web Configuration tab.
6. To view the xPico’s Web-Manager in the current DeviceInstaller window, click the
Go button. To open the Web-Manager in a web browser, click the External
