Migrating from Another Computer
As you migrate from another computer to a CN30 Computer, you need to
consider when converting other computer applications to run on the CN30
Computer, most APIs should work without changes. A few exceptions:
• Other computers may use the “\Storage Card” folder for nonvolatile
storage. You may need to change the application to store data onto the
“SDMMC Disk” folder instead of the “\Storage Card” folder if a Secure
Digital storage card is present in the system.
• Arrow and tab keys may be reversed from other computers. Keyboard
remapping is available on the CN30 Computer should you need to map
these keys like that of the other computer (see page 36).
Installing Applications Using the FTP Server
The CN30 has a built-in FTP server that connects to a network through
the 802.11b/g radio or Ethernet. You can use the server to transfer your
application file to the CN30. Another benefit of using the FTP server is
that you can create FTP scripts to automate the process of copying your
files to the CN30. This option is useful when you need to send files to a
large number of CN30s.
Installing Applications Using Wavelink Avalanche
You can use the Wavelink Avalanche™ device management system to
install applications on all of your wireless CN30s. The CN30 ships with the
Avalanche Enabler already loaded on it. Each time the Avalanche Enabler is
activated (typically on a warm boot), the CN30 attempts to connect to the
Avalanche Agent. When the CN30 connects to the agent, the Agent deter-
mines whether an update is available and immediately starts the software
upgrade, file transfer, or configuration update.
To use Avalanche to remotely manage the CN30
1 Install software packages and updates for the CN30 using the Avalanche
Administrative Console.
2 Schedule the CN30 updates or manually initiate an update using the Ava-
lanche Administrative Console.
For more information on using Wavelink Avalanche, contact your local
Intermec representative or visit the Wavelink web site at

Cabinet File Installation
CAB files (short form of “cabinet” files) are compressed folders as defined by
Microsoft. A “cabinet” file is a single file, usually suffixed with .CAB, that
stores compressed files in a file library. A compressed file can be spread over
