Micro125 User Guide 9

2: Introduction
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 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 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 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 Table 8-5.
Reserved Port Numbers.

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.
Hardware Address: 00-20-4a-_____-_____-_____
Micro125 User Guide 12

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
