Partner Name – This field allows you to specify which EC you will be creating a wireless
link with. This field only applies to Wireless Link mode.
Distance
– This field allows you to set the range of communication between two ECs in a
Wireless Link environment only. Select Normal Range for links less than 12 miles, or
Extended Range for links greater than 12 miles.
Encryption Enabled
– If checked, this allows you to define the encryption keys that the
EtherAnt II should use to encrypt and decrypt data that will be transmitted via the
wireless interface as shown in Figure 3.12. If not checked, the Encryption function will

Encryption Keys – These buttons will bring up a configuration window that allows you to

Use Key – This field allows you to select which key to use for encryption.
Encryption Type
– This field allows you to specify whether to use a 64-bit or a 128-bit
encryption key. For a 128-bit encryption key use a 26-character hex key or a 13-
character alphanumeric key. For 64-bit encryption key, use a 10 character hex key or a 5
character alphanumeric key.
Encryption Formats – The two formats used to develop encryption keys include
hexadecimal or alphanumeric as shown in Figure 3.13. Whichever format you choose,
the key that you enter is used in an encryption algorithm to encode the data that you send.
Only another wireless card using the same key can decode and receive the data.
Hexadecimal values are composed of the NULL character (0x00), 0-9, A-F and a-f.
Alphanumeric values are composed of all printable ASCII characters.
