2: Introduction

Protocol Support

The XPort 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.

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.

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

IP Address

Every device connected to an IP network must have a unique IP address. This address is used to reference the specific unit.

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.

XPort specifications

The Lantronix XPort is a compact and powerful embedded networking module that enables devices to connect to the Internet and communicate over a network. Small in size yet packed with features, the XPort is ideal for applications that require network connectivity without the complexity and cost associated with traditional networking solutions.

One of the standout features of the XPort is its small form factor. Measuring just 1.6 inches by 1.9 inches, it is designed for seamless integration into a variety of devices, making it a popular choice for manufacturers looking to add networking capabilities to their products without occupying much physical space.

The XPort utilizes the robust and widely used TCP/IP protocol stack, allowing it to facilitate reliable data communication over the Internet and other IP networks. This provides developers with a familiar framework for implementing network functionality, while also ensuring compatibility with various networking standards.

Equipped with a built-in web server, the XPort allows for easy configuration and management through a standard web browser. This user-friendly feature enables developers and end users to interact with the device effortlessly, simplifying tasks such as firmware updates and network settings adjustments.

Another key technology employed in the XPort is its serial-to-Ethernet capabilities. This feature converts serial data from devices into network packets, enabling legacy devices that communicate through serial ports to be connected to modern networks. This is particularly beneficial for industries with a significant number of legacy devices still in operation.

The XPort also incorporates security features, including SSL and SSH, which help protect data transmitted over the network. These security measures are essential in today's digital landscape, where data breaches and unauthorized access are growing concerns.

With its low power consumption and versatile applications, the Lantronix XPort is suitable for a variety of IoT applications, including healthcare devices, industrial automation, and smart metering. Its ability to operate in harsh environments enhances its appeal to manufacturers looking to deploy reliable networking solutions.

In summary, the Lantronix XPort offers a blend of compact design, advanced networking capabilities, and essential security features, making it a valuable asset for any project requiring efficient network connectivity. Its compatibility with existing technologies and ease of integration make it an ideal choice for modern IoT applications.
