Single-port serial-to-Ethernet gateway

The Lantronix UD1100NL2-01 connects one RS-232/422/485 device to a 10/100Base-TX network. It targets integrators who need to add remote management to legacy industrial equipment without rewriting host software. The DSTNI-EX processor runs at 48 MHz with 256 KB SRAM and 2 MB Flash to handle protocol translation.

10/100Base-TX speed and single-port constraint

The RJ-45 interface tops out at 100 Mbps, so throughput is limited to Fast Ethernet rates. Only one serial device can be attached, making the unit unsuitable for multi-drop or aggregated connections. No wireless or higher-speed wired uplinks are provided.

Compact DIN-rail mounting with TruPort redirector

The 3.7" x 2.8" x 0.9" enclosure fits standard DIN rails and weighs 14.40 oz. Installation requires assigning a static IP or using DHCP, then mapping the virtual COM port via the supplied TruPort software. Common issues include mismatched serial parameters such as baud rate or parity and firewall blocks on the redirector traffic.

Questions about this item

Should I choose the single-port or two-port UDS1100 model?

This item is the single-port UD1100NL2-01 with one 10/100Base-TX RJ-45 network connection; the two-port version is a different model.

What does the 10/100 network speed mean when the device server is installed?

The RJ-45 port negotiates at 10 Mbps or 100 Mbps full or half duplex, so serial traffic passes through at up to 100 Mbps wire speed.

Which serial interfaces does the UD1100NL2-01 support on its device port?

The device port handles RS-232, RS-422 and RS-485 signalling, selectable for the attached equipment.
