This security setup is typically used for wireless LAN communication.
It is based on WEP (RC4) (Rivest's Cipher 4) algorithm.
This type uses a data block length of 8 bits and provides selection of an
encryption key length.
* You can select an encryption key length from 64(40)/
128(104)/152(128) bits.
* "WEP (RC4) 152(128)" type cannot be connected to a wireless unit using wireless net-
work connection that comes with Windows XP.
This is a next-generation encryption method being standardized and is
stronger than "WEP (RC4)". This type uses 128-bit data block and
encryption key.
As any encryption key can be configured for the 128 bits, it is stronger
than WEP (RC4).
This type automatically updates its encryption key in a given interval
and is stronger than "WEP (RC4)".
It can be used for a Windows XP (modification program applied to
Service Pack 1) or Windows XP (Service Pack2) terminal.
It can be used for a Windows XP (modification program applied to
Service Pack 1) or Windows XP (Service Pack2) terminal.
* This type is enhanced in encryption and automatically updates its encryption key in a
given interval, and is stronger than "WEP (RC4)".
This is Omron's proprietary encryption.
encryption and decryption if an encryption method of "WEP RC4 64(40)",
"WEP RC4 128(104)", "WEP RC4 152(128)", or "OCB AES 128(128)" is
selected in [Encryption method] field (1).
Enter the same alphanumeric characters (within 31 characters) with the
attention for capitalization for communication partners.
Entered character is displayed as "*(asterisk)" or "•(black circle)".
(Example: **)
Selecting an encryption key and clicking <Apply> displays a key, generat-
ed by a character string entered in the [Key generator] field, in a text box
of the [WEP key] field.
Number of encryption key digits and characters in the [WEP key] text
boxes depends on a selected encryption method.
* If the [Input mode] field of [WEP key] is configured as ASCII Characters, a key generator
cannot be used.
* If None is selected in the [Encryption method], keys are not generated in the [WEP Key]
text boxes.
* If configured character strings are different between communication partners, encrypted
data cannot be decrypted.
* If they are directly set from [WEP key], the [Key generator] field shows nothing.
* As the 1st 24 bits of WEP (RC4) is automatically updated in a given interval, it is not dis-
played in WEP key text boxes.
* It is not compatible with other manufacturers' wireless LAN devices.
