What it is

The Lantronix XDT4851002-01-S is a compact device server that adds a single 10/100 Ethernet port to equipment with a serial interface. It suits engineers who need to connect legacy RS232, RS422 or RS485 devices to a local network without rewiring the machine.

Serial interface

The unit provides one DB9 female connector that supports RS232, RS422 and RS485 signalling at 300 bps to 921.6 Kbps. Buyers whose equipment uses a different connector type or requires multiple simultaneous serial ports should look elsewhere.

Installation notes

The module measures 1.14 by 1.30 by 9.45 inches and weighs 68 g, so it fits in tight cabinets and can be secured with a simple bracket. A common issue is mismatching the DCE pinout on the DB9 port; verify the cable wiring against the device manual before powering up.

Questions about this item

How does the single serial port handle RS232, RS422 and RS485 on one DB9F connector?

The DB9F connector is DCE pinned and supports all three serial standards on the same port, selectable by configuration for the attached device.

What network speed does the 10/100M RJ-45 Ethernet interface actually deliver?

The Fast Ethernet port auto-negotiates at 10 Mbps or 100 Mbps full-duplex, limited by the 10/100Base-TX standard on the single RJ-45 jack.

What are the exact dimensions and weight for mounting this device server?

The unit measures 29 mm high, 33 mm wide and 240 mm deep, weighing approximately 68 g for DIN-rail or panel installation.
