Wireless technology creates a new dimension in a rapidly emerging world of ubiquitous networking
collaboration in which billions of networked electronic devices work invisibly and jointly with each
other and with people. Making the right network technology decisions is a key factor for market
success and defines the competitive edge of your products.
The Digi Connect EM family of embedded modules enables original equipment manufacturers to
keep pace with ever-evolving networking technology by delivering complete and versatile embedded
network connectivity solutions. They are cost-effective and easy to implement in existing and new
product designs, while powerful enough to meet your future product performance needs.
Based on a unique common platform design approach, the Digi Connect EM and
Digi Connect Wi-EM embedded modules offer complete “drop-in” integration. This allows you to
build future-proof products based on a single design supporting secure 10/100Base-T wired and
802.11b wireless Ethernet connectivity. Digi Connect EM embedded modules make all of this
possible without the traditional complexities of hardware and software integration work, and at a
fraction of the time and cost required to create custom solutions.
The Digi Connect EM and Digi Connect Wi-EM embedded modules feature a variety of
connectivity options, such as two high-speed serial ports, an SPI master mode interface and nine
General Purpose Input/Output (GPIO) port options. For additional integration flexibility, they are
available in two low-profile population options, with or without onboard LED array and an
Ethernet connector. Additional customer-specific population options are
available on request.
Built on leading NetSilicon
®
32-bit NET+ARM technology, Digi Connect
®
embedded modules combine true plug-and-play functionality with the
freedom and flexibility of complete software customization. The proven
NetSilicon NET+Works
®
development platform provides a seamless
migration path to a fully integrated NetSilicon system-on-chip solution.

Plug-and-Play Modules
The Digi Connect EM and Digi Connect Wi-EM embedded modules
with plug-and-play firmware deliver instant and completely
transparent wired and wireless device server networking functionality.
They significantly reduce time to market by completely eliminating the
need for additional embedded hardware or software development.
Unique and industry-leading features such as a robust TCP/IP stack,
universal IP address assignment, integrated web server with user file
system, fully customizable web user interface, custom Java applet
support, enhanced security with strong DES/3DES/AES encryption
based on the SSL/TLS standard, intelligent device management via
SNMP, and patented RealPort
®
COM/TTY port redirection make it an
ideal solution for any application that requires versatility and
performance.
The Digi Connect Integration Kit provides a platform for evaluation,
rapid prototyping, and integration of Digi Connect embedded modules
with plug-and-play firmware. It offers the tools, sample code, and
documentation that make easy product integration and web-based
product customization possible.
