2. Connection indication in the “connectivity” pages however it is not a true connection (see “3 Address & 4 Address
Modes” above).
3.7 - 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” (Legacy) & 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.

WEP (64 bit) & (128 bit)
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 WI-MOD-E units in the
same system.
64bit WEP requires 10 Hexadecimal digits, and 128bit WEP
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
Default WEP Key
One of the four keys may be selected as the default key, and is used to encrypt transmitted messages from the configured
unit. A WI-MOD-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.
Authentication Mode =Open/Shared
WEP keys must be entered as pairs of hexadecimal digits separated by colons. Hexadecimal digits are in the range 0...9
and A...F
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.
