Digi Connect EM Family
®
Wired and Wireless Embedded Modules
The industry’s first interchangeable secure device server
module, delivering wired and wireless Ethernet network
connectivity that is cost-effective and easy to implement.
Overview
Based on a common platform design approach, the
Digi Connect EM and Digi Connect
®
Wi-EM offer complete
drop-in integration combined with true long-term product
availability. This allows you to build future-proof products
based on single design by simply selecting between the 10/100
wired and 802.11b module. The Digi Connect EM family
makes 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.
Built on Digi’s leading 32-bit NET+ARM processor technology,
the Digi Connect EM family offers two-port serial-to-Ethernet
functionality through Digi’s plug-and-play firmware, and the
freedom and flexibility of professional embedded software
development provided by the easy-to-use, cost-effective and
complete Digi JumpStart Kits

Digi JumpStart Kit® for NET+OS®
This royalty-free turnkey solution for embedded software development is based on the ThreadX
Real-Time Operating System (RTOS), one of the most reliable and field-proven RTOS solutions
available. In addition to ThreadX, NET+OS provides the integrated building blocks needed
to create product solutions with leading network security using Digi embedded modules and
microprocessors.
For professional NET+OS software development, the Microsoft Windows based Digi ESP™
Integrated Development Environment (IDE), with graphical user interface and a high-speed
USB 2.0 hardware debugger, is provided out-of-the-box.
