ABB 3BHB004692R0002 5SXE01-0127 module

The preferred encryption type is WPA (WiFi Protected Access). You should only select WEP (wired equivalency protocol) for use with an older client radio that only has WEP encryption. For compatibility with clients that do not support WPA, you can select WPA+WEP128 (bits) or WPA+WEP64 (bits) as the encryption type. Then the older clients can connect to an access point using the WEP setting, but new clients will use WPA and the RLXIB radios will still use WPA among themselves. IMPORTANT: If WPA+WEP is selected, some clients using WPA might not be able to connect unless you use a WEP key other than number 1, due to limitations in these clients. In such cases, you should set a WEP key other than key 1 and set this same key in all clients that are using WEP. See WEP key

Encryption type

WEP is the original security protocol used by 802.11 networks, but WPA offers better protection against attacks, for several reasons: WPA distances the encryption key from the actual data by performing several algorithms to the key before generating the encrypted data, it performs dynamic key management by changing keys frequently, and it performs message integrity checks to prevent forgery and replay. You can also select WEP 128, WEP 64, or None (no encryption) as the encryption type, but none of these settings are recommended. Note: If an RLXIB is set to use WPA+WEP, it will connect to other radios set to WPA only or WPA+WEP, but it will not communicate with radios set to WEP only. Likewise, an RLXIB in client mode with WPA+WEP selected will not connect to an access point with WEP only selected.

WPA phrase 

To use WPA encryption on packets sent between the radios, enter a WPA pass phrase of between eight and 63 normal keyboard characters. This phrase automatically generates an encryption key of 128 hexadecimal characters. This field is only available if you select WPA as the encryption type. The default WPA-AES Phrase when a module ships is 'passphrase'.
