Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual
3.5 Security Menu
Select the Radio Encryption level from the drop down menu on the Main index page and then press the “Save Changes” button.
Available encryption levels are - “None”,“WEP (64-bit)”, “WEP (128-bit)”, “WPA PSK (TKIP)”,“WPA PSK (AES)”, “WPA2 PSK (AES)”, “WPA PSK/
WPA2 PSK”& WPA-Enterprise. The default setting is “None.”
You will now need to go to the “Security Menu”and enter in the encryption keys (WEP), passphrase (WPA), etc.
Encryption Keys 1 to 4
These are the keys used to encrypt radio data to protect data from
unwanted eavesdroppers when WEP Encryption is selected.
These keys should be the same for all BU-245U-E units in the
same system.
Authentication Mode =Open/Shared
One of the four keys may be selected as the default key,and is
used to encrypt transmitted messages from the configured unit.
A BU-245U-E can receive and decrypt a message from a module
that has a different default key index as long as each module has
the same key configured at the same index.
WEP keys must be entered as pairs of hexadecimal digits
separated by colons. Hexadecimal digits are in the range 64bit WEP requires 10 Hexadecimal digits, and 128bit WEP
0...9 and A...F. requires 26 Hexadecimal digits. For example,
12:AB:EF:00:56. for 64bit encryption, and
12:AB:EF:00:56:15:6B:E4:30:C8:05:F0:8D for 128bit encryption
Encryption keys must not be all zeros, i.e., 00:00:00:00:00
WEP Open Authentication Mode
• Station sends an authentication request to the Access Point
• Access Point then authenticates the Station
• Station then associates with the Access Point and joins the
network.
WEP Shares Authentication Mode
• Station sends an authentication request to the Access Point
• Access Point then sends a text based message to the Station
• Station uses its own WEP key to encrypt the text based
message and sends it back to the Access Point.
• Access Point then decrypts the message using its on WEP key
and if it matches authenticates the Station.
• Station then associates with the Access Point and joins
the network.
