WiPort is a wireless embedded device server that provides a network-enabling
solution based on the IEEE 802.11b wireless standard. WiPort allows Original
Equipment Manufacturers (OEMs) to add wireless connectivity to their products by
incorporating it onto a circuit board.
The WiPort functions independently of a PC, providing a fully integrated solution that
combines a processor, memory, 802.11b transceiver, and dual high-speed serial
ports into a single compact module. It includes an operating system, an embedded
Web server, full TCP/IP protocol stack, and WEP security. In addition, the WiPort
sends email alerts and supports numerous other network communication protocols,
including ARP, UDP, TCP, ICMP, Telnet, AutoIP, DHCP, HTTP, SNMP, and SMTP.
For OEMs who wish to customize the user interface by employing common and
familiar tools, the WiPort serves applets to a Web browser, resulting in interactive
Web pages. This customization of HTML Web pages and configuration screens
tailors the WiPort to fit unique requirements.

Introduction
2-2 WiPort™ User Guide
Applications
The WiPort device server connects serial devices such as those listed below to
wireless and Ethernet networks using the IP protocol family.
Remote sensing
CNC controllers
Data collection devices
Telecommunications equipment
Data display devices
Security alarms and access control devices
Time clocks and terminals
Protocol Support
The WiPort device server uses the TCP/IP protocol stack for network
communications. Other 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.
SMTP for e-mail transmission.
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 and
assigning IP addresses (as well as setting other configurable parameters):
DeviceInstaller: Configure the ports and other features on the WiPort using a
Graphical User Interface (GUI) on a PC attached to a network. (See 3: Configuration
using DeviceInstaller.)
Web-Manager: Through a web interface, configure the WiPort and its settings using
the WiPort’s Web-Manager. (See 4: 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 5: Configuration via Serial
Mode or Telnet Port.)
Introduction
WiPort™ User Guide 2-3
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 WiPort
using DeviceInstaller.
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 WiPort 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, refer to Table 5-5. Reserved Port Numbers.
