Building Ethernet connectivity into a product is no
simple task. It requires a significant investment in
hardware and software integration – often in areas
outside of core competencies. So why build it
yourself when there is a better alternative?
The Micro125 embedded device server provides an
integrated solution to add proven Ethernet connectivity
to an existing design quickly and economically, and
with a high level of flexibility.
Device networking starts with a Device Server™
.
These amazing products enable most any device with
serial capability (TTL) to become a fully functional
member of an Ethernet network. Device Servers
include all of the elements needed to network-enable
your products – a processor, real-time operating
system (RTOS), a robust TCP/IP stack, a web server,
and a network connection. All the connected product
additionally needs is a header, providing connections
to a power source and to a TTL serial port.
The Micro125 brings over a decade of device networking
experience, rock-solid IP firmware, extensive
applications support and advanced encryption standards
to industrial and commercial environments.
Measuring only 49 x 40 mm the Micro125 can easily
fit into almost any size serial device that would
benefit from network connectivity. It includes a
serial interface TTL connector and 10/100 Base-T
Ethernet RJ45 jack. The Micro125 includes the same
IP protocol stack found on the other Lantronix
embedded products.
RoHS-compliant, the Micro125 meets Directive 2002/95/EC
on the restriction of the use of certain hazardous
substances in electrical and electronic equipment.
The Lantronix Micro125 is a board-level product
for OEM users who want to embed proven mainstream
Ethernet connectivity in their products quickly
and economically.

Your Products Quickly and Economically
