Menus and Parameters

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.

4.2.6.7.5Default Multicast Key (AU only)

The Multicast Default Key defines the Key to be used for encrypting multicasts and broadcasts when Data Encryption is enabled.

Available values range from 1 to 4.

The default is KEY # 1.

4.2.6.7.6Key # 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.

4.2.6.7.7Promiscuous 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.

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.
