4: Using Setup Mode for Configuration

Note: To connect an ASCII terminal to a host using the unit for login purposes, use the remote port number 23 (Internet standard port number for Telnet services).

DisConnMode

This setting determines the conditions under which the unit will cause a network connection to terminate.

Note: In DisConnMode (Disconnect Mode), DTR drop either drops the connection or is ignored.

(1)The XPort sends the "Terminal Type" upon an outgoing connection.

(2)A password is required for a connection to the serial port from the network.

(3)The TCP connection closes even if the remote site does not acknowledge the disconnection.

(4)When there is a network connection to or from the serial port, the state LED turns off instead of blinking.

(5)When Ctrl+D or Hex 04 is detected, the connection is dropped. Both Telnet mode and Disconnect with EOT must be enabled for Disconnect with EOT to function properly. Ctrl+D is only detected going from the serial port to the network.

(6)When DTR transitions from a high state to a low state, the network connection to or from the serial port drops.

Flush Mode (Buffer Flushing)

Using this parameter, you can control line handling and network buffers with connection startup and disconnect. You can also select between two different packing algorithms.

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.
