4.2.6.7.4 Default Key (SU only)
The Default Key defines the Key to be used for encrypting/decrypting t
authentication messages (Shared Key mode) and/or data frames (Data
Encryption enabled). The AU learns the Default Key from the SU provi
one of the Keys defined in the AU. The AU may use different keys when
authenticating and/or communicating with different SUs.
Available values range from 1 to 4.
The default is KEY # 1.
4.2.6.7.5 Default Multicast Key (AU only)
rypting
es range from 1 to 4.
The default is KEY # 1.
4.2.6.7.6 Key # 1 to Key # 4
The Key # options enables defining the encryption key to be used for initializing
the pseudo-random number generator that forms part of the
encryption/decryption process. The Keys must be set before the Shared Key
authentication algorithm or Data Encryption can be used. To support proper
operation, both the Key # and the content must be identical at both sides of a
wireless link.
Each Key is a string of 32 hexadecimal numbers. For security reasons, it is a
“write only” parameter, displayed as a string of asterisks (“*”).
The default for all 4 Keys is 000…0 (a string of 32 zeros), which means no key.
4.2.6.7.7 Promiscuous Authentication (AU only)
The Promiscuous Authentication mode enables new SUs to join an active cell
where Shared Key operation and/or Data Encryption are used, even if this SU
does not have the correct security parameters. In promiscuous mode, all
downlink transmissions (from AU to SUs) are not encrypted, allowing remote
configuration of security parameters, regardless of the current settings in the SUs
of the parameters related to data encryption. After a new SU joins the cell it
should be remotely configured with the proper parameters (or upgraded). When
the SU is configured properly, the Promiscuous Mode should be disabled.
The default is Disable.

The Multicast Default Key defines the Key to be used for encrypting/dec

NOTE
Do not leave the AU in the enabled Promiscuous Authentication mode for prolonged periods. Use it
only when absolutely necessary, perform the required actions as quickly as possible and disable it.
The unit will return automatically to Promiscuous Authentication disabled mode after reset.
