Introduction
Thank you for choosing a data communications product from Digi International. Digi
products are extremely versatile and may be used in a wide variety of applications. It would
not be possible to describe in detail all such applications in a single guide. Consequently,
this guide has been written for use by technically competent personnel with a good
understanding of the communications technologies used in the product, and of the
requirements for their specific application.
Digi International designs and manufactures a wide range of both wireline and wireless
network routing products. For a complete, up-to-date list of current products, please visit
the Digi International web site at www.digi.com.
Whilst each of these models provide a different combination of hardware and software
features, the basic method of configuration using the web interface or command line is the
same in each case. This guide describes the operation of standard features available across
the whole product range. Consequently, some of the features described in this guide may
only be available on certain models or must be purchased as optional “feature packs”. You
should refer to the specification of the particular model you have purchased to ascertain
which features are supported as standard.
In addition to a comprehensive range of communications capabilities, our products provide a
combination of powerful, yet easy to use, configuration, management and diagnostic tools.
These include a protocol analyser, a time-stamped event log and remote management via
the web interface or via a Telnet session.
In many applications, the serial ports will be configured to appear as if they were standard
“AT” modems and behave accordingly. However, many other standard protocols are
supported (e.g. B- and D-channel X.25, PPP, TPAD, V.120, etc.). This makes it simple and
cost-effective to migrate existing terminal equipment, which uses the analogue telephone
network, to faster, more reliable and cost effective “wireline” or wireless digital services.
All major features of the unit can be configured using a standard Web browser. This can be
done locally (via a serial or LAN port), or remotely via a WAN connection. A built-in Web-
server and flexible FLASH-memory based filing system mean that the unit can also be
customised to provide application specific functions, statistics and diagnostic information.
