The XPort™ connects devices through a TCP data channel or through a Telnet connection
to computers or another Device Server. Datagrams can be sent by UDP.
The XPort™ contains a web [http] server that allows presentation of custom content and can
be easily configured through the server.
The XPort™ has 3 programmable IO pins that can be used to monitor or control attached
devices.
1.1 Features
The XPort™ device server is a miniaturized version of a modular serial-to-Ethernet
converter based in principle on an existing Lantronix Modular Serial-to-Ethernet module.
The XPort™ device server package contains a DSTni-LX controller, with 256K bytes of
SRAM, 2K bytes of boot ROM, and integrated AMD 10/100 PHY.
The package also contains a 3.3-volt serial interface, 4-Mbit flash memory, Ethernet
magnetics, power supply filters, reset circuit, +2.5V regulator, a 25-MHz crystal (Ethernet),
48-MHz crystal (DSTni-LX) and Ethernet LEDs. The XPort™ re3.3-volt power and is
designed to operate in an extended temperature range (see technical data).

1.2 Protocol Support
The XPort™ uses the Internet Protocol (IP) for network communications and 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.
