Configuring Access Point Security 6-17
5. Configure the WEP 64 Settings or WEP 128 Settings field as required to define the Pass 
Key used to generate the WEP keys. These keys must be the same between the AP-5131 and 
its MU to encrypt packets between the two devices.
Default (hexadecimal) keys for WEP 64 include: 
Pass Key  Specify a 4 to 32 character pass key and click the Generate button. 
The pass key can be any alphanumeric string. The AP-5131, other 
proprietary routers and Symbol MUs use the algorithm to convert 
an ASCII string to the same hexadecimal number. MUs without 
Symbol adapters need to use WEP keys manually configured as 
hexadecimal numbers.
Keys #1-4 Use the Key #1-4 areas to specify key numbers. The key can be 
either a hexadecimal or ASCII depending on which option is 
selected from the drop-down menu. For WEP 64 (40-bit key), the 
keys are 10 hexadecimal characters in length or 5 ASCII characters. 
For WEP 128 (104-bit key), the keys are 26 hexadecimal characters 
in length or 13 ASCII characters. Select one of these keys for 
activation by clicking its radio button.
