Serial-to-Ethernet Modules
Lantronix XPort Direct+ Embedded Serial-to-Ethernet Module
XPort Direct+ is an embedded device server module that adds 10/100 Ethernet, a web server and a TCP/IP stack to any product whose microcontroller has a serial port, packaged inside an RJ45 jack under 12 mm tall.

Overview
About the Lantronix XPort Direct+
Lantronix lists XPort Direct+ as In Production-NRFND, meaning it is still produced but not recommended for new designs; no successor is named on the product page. XPort Direct+ (also written XPort Direct Plus) acts as a networking co-processor. The host microcontroller sends data over a CMOS logic-level serial port, and XPort Direct+ packetizes it into TCP or UDP over Ethernet and returns incoming packets to the serial interface, so the host never handles TCP/IP itself.
The serial interface is asynchronous CMOS, 5 V tolerant, at 300 bps to 921,600 bps with RTS/CTS or XON/XOFF flow control and three software-selectable PIO pins. The network side is auto-sensing 10Base-T/100Base-TX with MAC, PHY, magnetics and RJ45 integrated. A DSTni-EX 16-bit x86 CPU with 256 KB SRAM and 512 KB flash runs the stack, a web server with 384 KB of page storage, SNMP, Telnet, DHCP and AutoIP, and 256-bit AES encryption.
The module runs on 3.3 VDC at 200 mA typical, operates from -40°C to 85°C and measures 43.3 x 31.75 x 11.76 mm with 2 x 12-pin, 2 mm headers. Windows-based DeviceInstaller configures one or more modules across a subnet, Com Port Redirector software is included, and firmware updates via TFTP or the serial port.
Key capabilities
- Ethernet inside the RJ45
- MAC, PHY, magnetics and processor sit in a jack-sized module under 12 mm tall, so a board gains Ethernet without a separate network layout.
- No TCP/IP on the host
- The module handles the full protocol stack and serial-to-Ethernet application, letting a limited host microcontroller stay focused on its own job.
- Built-in web server
- 384 KB of web page storage supports browser-based remote configuration, monitoring, upgrades and troubleshooting of the end product.
- 256-bit AES encryption
- AES Rijndael encryption and password protection secure data passing between the device and the network.
- Industrial temperature range
- Operating and storage temperatures span -40°C to 85°C, suiting metering, building automation and outdoor-adjacent products.
How to choose the right XPort Direct+ part number
XPD1001000-01 is the standard XPort Direct+ module in bulk packaging for production. XPD100100S-01 is the same module in sample packaging for prototyping and evaluation. XPDNC2000-01 is the variant without the RJ45 connector, for designs that place their own Ethernet jack. All three share the 10/100 Ethernet interface, CMOS serial host connection and -40°C to 85°C operating range.

XPort Direct+ FAQ
Is XPort Direct+ recommended for new designs?
No. Lantronix lists XPort Direct+ as In Production-NRFND, so it is still produced for existing designs but not recommended for new ones. The product page does not name a specific replacement.
What serial interface does XPort Direct+ use?
It connects to the host microcontroller through an asynchronous CMOS serial port that is 5 V tolerant, at 300 bps to 921,600 bps. Lantronix also describes the module as RS-232/RS-485 ready.
What is the difference between XPD1001000-01 and XPDNC2000-01?
XPD1001000-01 is the standard module with its integrated RJ45 jack, in bulk packaging. XPDNC2000-01 is the version without the RJ45 connector, for products that provide their own Ethernet jack.
What power does the XPort Direct+ module need?
It runs on 3.3 VDC and draws 200 mA typical, 240 mA maximum. The module operates and stores from -40°C to 85°C, weighs 9.6 g and mounts through 2 x 12-pin, 2 mm headers.
How is XPort Direct+ configured?
Use the Windows-based DeviceInstaller to assign IP addresses, load firmware and custom web pages across a subnet. The module can also be managed through its internal web server, Telnet, SNMP or the serial port.
