Digi Connect Wi-EM 9210 Overview
The embedded modules are part of the Digi Connect family of device sewers that provide
simple, reliable and cost-effective network connections for serial devices. They provide
fully transparent serial device connectivity over industry-standard wireless connections and
allow both equipment manufacturers and systems integrators to network-enable products at
a fraction ofthe time and cost required to develop a custom solution. It is a highly flexible
and compact single component solution with a robust onvboard TCP/lP stack and wireless
support. Features include the following:
I 32~bit Digi WifEM 9210 processor with ARM926EJ—S core
I 4MB Flash and EMS RAM on board
- 2 High Speed Serial Ports
l SP! Muster Mode Interface
l 9 General Purpose Input/Output Port Options
I NetSilicon NET+Works platform for embedded software development
From medical systems to building control and industrial automation, in virtually any
application where embedded serial connectivity over WLAN is needed, the embedded
module is the ideal choice, delivering higheperfomtance functionality

Types of Modules
Cautions
To guard against damage to the module due to electrostatic discharge (BSD), do not
remove it from its protective packaging until you have been properly grounded. To ground
yourself, put the wrist strap on (included in the package) and then attach the clip to a metal
surface,
I Input voltage for the module is 3.3 VDC.
