Industrial Device Server

The Lantronix XPress-DR+ connects two serial devices to an Ethernet network for remote monitoring and control. It targets engineers managing PLCs, drives, motion controllers or barcode scanners in manufacturing, distribution or refinery environments. The unit provides web-based configuration and supports DHCP, BOOTP and ARP for straightforward network integration.

Upgrade from Direct Cabling

This server replaces point-to-point serial wiring or basic terminal servers that lack Ethernet connectivity. The jump is worthwhile when equipment must be accessed from a central SCADA system or when devices are spread across a large facility. It adds network reach without replacing existing serial controllers or instrumentation.

Fast Ethernet and Serial Limits

The RJ-45 port operates at Fast Ethernet speeds, which caps throughput for high-bandwidth logging applications. Only two serial ports are available, supporting RS-232, RS-422 and RS-485 with flow control. The 48 MHz processor and 256 KB SRAM limit concurrent session handling for dense multi-drop networks.

Questions about this item

What are the exact height, width and depth of the XPress-DR+ so I can confirm it fits my DIN-rail cabinet?

The unit measures 2.24 inches (57 mm) high, 4.84 inches (123 mm) wide and 3.46 inches (88 mm) deep.

How do I connect the two serial ports and the Ethernet uplink during first-time setup?

Wire each serial device to one of the two DB-9 ports using RS-232, RS-422 or RS-485 as required, then plug the Ethernet cable into the single RJ-45 jack; the common mistake is reversing the TX/RX lines on the serial side.

When will the internal SRAM or flash need replacement in a continuous industrial deployment?

The 256 KB SRAM and 2 MB flash are soldered and rated for the product's service life; no field replacement is scheduled.
