PDT 8100 Series with Windows Mobile 2003 Software for Pocket PCs Product Reference Guide
The AP and the terminal are required to use the same encryption algorithm to
associate and transmit data. If an AP is set to Open System and an adapter is set
to 40-bit or 128-bit, no association takes place. Similarly, if an adapter is set to
Open System and an AP is set to 40-bit or 128-bit, no association takes place.
If an AP is set to 40-bit and an adapter is set to 128-bit, the adapter can associate
to the AP, but no data transmission and reception can take place.

Use the Open System option as the default setting when no data packet
encryption is needed over the network. Selecting this option provides no
security for the data being transmitted over the network. The window
displays only the OK and Cancel buttons.
Select WEP for the adapter to use the WEP keys for encryption. The window
displays several radio buttons and edit buttons to configure the WEP keys.
Select 40-bit or 128-bit key lengths (128-bit is the default). WEP keys are
manually entered in the edit boxes. Only the required number of edit boxes
for a key length is displayed (10 Hex digit value for 40-bit keys, 26 Hex digit
values for 128-bit keys). Use the Key radio buttons to configure the four WEP
keys. The adapter uses the selected key. Tap ResetKeys to set the
encryption key to the default values.
Note: The default Hex digit keys are visible any time they are used. As a
security precaution after setting the key values for the network, the digits are
replaced with asterisks * within the Encryption key fields.
If the associated access point is using an optional Passkey, the "active"
adapter WLAN profile is required to use one as well. The Passkey is a plain
text representation of the WEP keys displayed in the Encryption property
window. The Passkey provides an easy way to enter WEP key data without
having to remember the entire 40-bit (10 character) or 128-bit (26 character)
Hex digit string.
Tap Passkey to display the Passkey screen. Enter an easy-to-remember 4
to 32 character string to be used as the WEP algorithm. Click OK. The
access point transforms the Passkey string into a set of four WEP keys using
MD5 algorithms and displays them in the WEP fields. These are the new
WEP keys for the adapter profile. Once displayed in the WEP key fields, the
adapter profile behaves as if the keys were entered manually.
