I've used one of these before. They are useful for attaching serial devices to an Ethernet network. It's a lot cheaper and easier than trying to put a PC with enough serial ports near every device you need to talk to. The ones I worked with were part of a radio modem sold by MaxStream, now part of Digi International.

We used dedicated terminal servers for this function years ago. No PC required. DEC and Allied Telesis made them. Now I feel old.

That is essentially what these are. The default Lantronix firmware allows you to connect to the device on a specific TCP port and talk to the serial device on the other side. You configure them over HTTP or Telnet.

It says 16MB. Nowhere can I find what the CPU architecture is though.

In the same sentence. :) > The 32-bit RISC CPU appears to be the same, but instead of coming standard with 8MB SDRAM, it now ships with the previously optional 16MB.

IIRC RISC is a category of architecture, rather than a concrete implementation

Out of curiousity does anyone use any of these style devices? And if so what for?

Robotics, consolidate all your sensors and controllers onto Ethernet. Its quite hard finding a microcontroller with good Ethernet.

The arduino yun [1] combines an linux-based SoC with a microcontroller on a single board. So you can have both, networking and applications in practically any language, and an internal interface to a microcontroller.

For only accessing a rs232 serial port over ethernet, there are easier solutions. But if you need multiple of such ports, sensor access, etc. its quite a nice combination.
