Security Button - 11 Mb RF Security Setup
The Security button is located to the right of the Frequency button. Clicking this button will open a
new dialog box that allows you to change the security options of the interface. These settings are
used to encrypt data that will be transmitted by the 11 Mb RF port and also to decrypt data that is
received by 11 Mb RF port. You may define up to 4 encryption keys to be used for decrypting
incoming data and one key for encrypting outgoing data.
Check the box labeled Enable Encryption to enable the encryption features. You will still need to
define at least one encryption key before your wireless traffic will be transmitted using wireless data
encryption.
The Encryption Key can be defined using either:
• 5 alphanumeric characters in the range of "a-z", "A-Z", and "0-9"
• A 10 digit hexadecimal value using the range "A-F" and "0-9". If you choose to use the
hexadecimal method, use the prefix "0x" (zero, x) in defining the key
Examples:
• Alphanumeric: a5F2z
• Hexadecimal: 0xA95F2BR39K
Write down the values you enter as Encryption Keys and store them in a secure place. The values you
enter will only be visible when they are entered for the first time. Each time this option is displayed
after the initial setup, the values will appear only as "xxxxxxxxxx"
