Maximizing Battery Life
There are several things that you can do to maximize the life of
your fully charged battery.
• Set the backlight timeout to 10 seconds.
• Verify that Radio Power Management is enabled (Fast PSP).
Enabling radio power management allows your radio to
switch between awake and sleep modes based on network
traffic.
• Verify that each setting under Power Management has a value
of 1 minute for a combined automatic shutoff time of 3
minutes.
You can use Intermec Settings to easily make all of these
configuration changes. For help, see “Configuring the CN2G
Locally With Intermec Settings” on page 24.
Checking the Battery Status
The easiest way to tell the status of your battery is to look at the
battery icon on the status bar of your CN2G.

Microsoft, you can begin implementing your WPA, 802.1x,
or WEP security solution now.
• Funk security provides everything you get with Microsoft
security with the addition of CCX v1.0 compliance. Funk
security also enables you to use LEAP and TTLS
authentication on your CN2G. If you choose Funk security,
you need to:
a select Funk security as your security choice.
b select a profile.
Note: Your choice does not depend on your authentication
server. For example, you can choose Funk security if you use
Microsoft Active Directory® to issue certificates.

Using WPA Security
Wi-Fi Protected Access (WPA) is a strongly enhanced,
interoperable Wi-Fi security that addresses many of the
vulnerabilities of Wired Equivalent Privacy (WEP). Instead
of WEP, WPA uses Temporal Key Integrity Protocol (TKIP)
for its data encryption method.
Currently, WPA satisfies some of the requirements in the IEEE
802.11i draft standard. When the standard is finalized, WPA
will maintain forward compatibility.
WPA runs in 802.1x (Enterprise) mode or PSK (Pre-Shared
Key) mode:
• In Enterprise mode, WPA provides user authentication using
802.1x and the Extensible Authentication Protocol (EAP).
That is, an authentication server (such as a RADIUS server)
must authenticate each device before the device can
communicate with the wireless network.
• In PSK mode, WPA provides user authentication using a
shared key between the authenticator and the CN2G. WPA-
PSK is a good solution for small offices or home offices that
do not want to use an authentication server.
To use WPA security, you need:
• an authentication server (Enterprise mode only).
Note: You can also use a MobileLAN access WA2XG
product as an authentication server. For help, see the
MobileLAN access WA2XG System Manual (P/N 074921).
• user and root certificates (if you plan to use TLS for
authentication)
• an access point with an 802.11b/g radio that supports WPA.

Using LEAP Security
Lightweight Extensible Authentication Protocol (LEAP), also
known as Cisco-Wireless EAP, provides username/password-
based authentication between a wireless client and a RADIUS
server. In the 802.1x framework, traffic cannot pass through an
Ethernet hub or wireless network access point until it
successfully authenticates itself.
The station must identify itself and prove that it is an authorized
user before it is actually allowed to use the LAN. LEAP also
delivers a session key to the authenticated station, so that future
frames can be encrypted with a key that is different than keys
used by others’ sessions.
To use LEAP security, you need:
• a RADIUS server.
• a Cisco access point with an 802.11b/g radio.

Chapter 3 — Developing and Installing Applications
Developing Applications for the CN2G
The CN2G Handheld Computers run applications programmed
in Microsoft Embedded Visual C++. The CN2G can also run
applications developed for the .NET Compact Framework using
Microsoft C# and Visual Basic .NET.
Use this section to understand what you need to:
• Develop a new application for the CN2G.
• Develop a web-based application for the CN2G.
Developing a New Application
Use the Intermec Developer’s Toolkits for AIT-III CD to help
develop your C++ and .NET applications. The CD contains two
toolkits, the Intermec AIT-III Developer’s Toolkit and the
Intermec AIT-III .NET Developer’s Toolkit. The toolkits
include hardware and software requirements, all of the functions
that are supported by the CN2G, and instructions on how to
use these functions.
The Developer’s Toolkits for AIT-III is available on CD (P/N
074925) or as a download from the Intermec web site at
www.intermec.com/AIT.
You need these hardware and software components to use the
Intermec toolkits:
• Pentium PC, 400 MHz or higher
• Windows 2000 (Service Pack 2 or later) or Windows XP
(Home, Professional, or Server)
• For native C++ development, Microsoft eMbedded Visual
C++ version 4.0 with eVC++ Service Pack 2
• For .NET Development and Compact Framework (C# and
VB.NET), Microsoft Visual Studio .NET 2003
• 128MB RAM (196MB recommended)
• 360MB hard drive space for minimum installation (720MB
for complete)

Chapter 3 — Developing and Installing Applications
• CD-ROM drive compatible with multimedia PC
specification
• VGA or higher-resolution monitor (Super VGA
recommended)
• Microsoft Mouse or compatible pointing device
Developing a Web-Based Application
You can develop web-based data collection applications for use
on the CN2G. For help, see any HTML source book. The
CN2G contains Internet Explorer (IE) 6.0 for Windows CE for
you to use. The Microsoft standard IE 6.0 is available from the
desktop and provides all of the common elements you expect to
find.
To open Microsoft Internet Explorer
• Double-tap Internet Explorer from the desktop. The
Internet Explorer default window appears.
Installing Applications on the CN2G
There are several ways you can install applications on the
CN2G:
• You can package your application as a cabinet (.cab) file.
• If you have a simple application, you may only need to deliver
the .exe file.
• You can copy a directory structure that contains the
application, supporting files, DLLs, images, and data files.
Intermec recommends using CAB files to install your
applications. The CN2G uses standard Windows CE CAB files
and will install third-party CAB files. After the CN2G executes a
CAB file, it deletes the file. To keep your CAB files so that they
can be installed when you perform a cold boot, you need to save
them to the \DiskOnChip\Persistent Copy\CABFiles directory.
On a cold boot, the CAB files are copied to the \CABFiles
directory in the object store where they are executed and deleted.
The original copy remains in the \DiskOnChip\Persistent
Copy\CABFiles directory to be installed on the next cold boot.

• The DiskOnChip folder
If you have an SD card inserted in your CN2G, it appears as the
SDMMC Disk folder. This folder is the recommended location
for placing your application install files.
The DiskOnChip folder is an area of storage that is part of the
CN2G flash memory. This storage area is not deleted during a
cold boot.
There are several ways you can install files and applications on
the CN2G:
• ActiveSync
• SD Card
• Wavelink Avalanche
The following sections explain how to use each one of these
processes to install your application on the CN2G.

Problems While Scanning Bar Codes
Problem
Solution
You cannot see a red beam of light
from the scanner when you press the
Scan button or one of the Side Scan
buttons and aim the scanner at a bar
code label.
There are three possible problems:
•
You may be too far away from the bar code label.
Try moving closer to the bar code label and scan
it again.
•
•
You may be scanning the bar code label “straight
on.” Change the scanning angle and try again.
The PSM files may not be correctly installed. For
help, see “Upgrading the Persistent Storage
Manager Files” on page 62.
You can test the effective range of the scanner. Move
within 61 cm (2 ft) of a wall and test the scanner.
You need to be within the scanning range to scan
bar code labels. For help scanning bar codes, see
“Scanning Bar Codes” on page 15.
When you release the Scan button or
Side Scan button, the Good Read
light does not turn off.
The Good Read light will remain on if you
configure the CN2G to use continuous/edge
triggering. If you configure the CN2G for level
triggering and the Good Read light remains on,
there may be a problem. Press the Scan button or
one of the Side Scan buttons again without
scanning a bar code label. If the light is still on,
contact your local Intermec service representative.
The scanner will not read the bar code Make sure you aim the scanner beam so it crosses
label.
the entire bar code label in one pass.
The angle you are scanning the bar code label may
not be working well, or you may be scanning the
label “straight on.” Try scanning the bar code label
again, but vary the scanning angle.
The bar code label print quality may be poor or
unreadable. To check the quality of the bar code
label, try scanning a bar code label that you know
will scan. Compare the two bar code labels to see if
the bar code quality is too low. You may need to
replace the label that you cannot scan.

is enabled. Use Intermec Settings to check the
symbologies. If your bar code symbology is disabled,
enable it and then try scanning the bar code label
again.
Make sure that the application you are running on
the computer is expecting input from a bar code.
You may need to use the input panel to enter this
information instead of scanning it.
The scanner does not read the bar
code labels quickly, or the scanning
beam seems to be faint or obscured.
The scanner window may be dirty. Clean the
window with a solution of ammonia and water.
Wipe dry. Do not allow abrasive material to touch
the window.
You scan a valid bar code label to
enter data for your application. The
data decoded by the CN2G does not
match the data encoded in the bar
code label.
The computer may have decoded the bar code label
in a symbology other than the label’s actual
symbology. Try scanning the bar code label again.
Make sure you scan the entire label.
To operate the computer quickly and efficiently,
you should only enable the bar code symbologies
that you are going to scan.
