Introduction

About This Guide

Purpose The purpose of this guide is to enable developers to integrate

the Digi One EM into other devices, enabling these devices to

make use of the Digi One EM’s rich networking features.

Audience This document is written for developers tasked with

integrating Digi One EM device servers into other devices.

Scope This document provides the information required for electrical

integration of the Digi One EM into another device. It does

not address how to configure or administer the device server

or how to write applications to use its functionality. These

topics are covered in other documents in the library.

Introducing the Digi One EM

Product Overview

The Digi One EM is part of the Digi One Family of single port

device servers that provide simple, reliable and cost-effective

network connections for serial devices. The Digi One EM

provides fully transparent serial device connectivity over

industry-standard Ethernet connections and allows both

equipment manufacturers and systems integrators to

network-enable products at a fraction of the time and cost

required to develop a custom solution. It is a highly flexible

and compact single component solution with a robust on-

board TCP/IP stack and 10/100 Base-T Ethernet support.

From medical systems to building control and industrial

automation, in virtually any application where embedded

serial connectivity over Ethernet is needed, the Digi One EM

is the ideal choice, delivering high-performance functionality.

Cautions • To guard against damage to the Digi One EM due to elec-

trostatic discharge (ESD), do not remove it from its pro-

tective 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.

• Input voltage for the Digi One EM must be in the range of

5VDC to 9VDC.
