Chapter 4: XPress DR+W
XPress DR+ User Guide

Point to many wireless devices at once is called multicast and uses the group
encryption method.
To receive broadcast and multicast messages, the group encryption for all
wireless devices communicating with the same access point must be equal. If
any of these devices is WEP-only (no support for WPA), set the encryption to
TKIP+WEP
.
A group encryption lower than the pairwise encryption is necessary to use higher
security with the XPress DR+W than other devices connecting to the same
Access Point can support.
CCMP is also called AES on products of other manufacturers. CCMP is an
extension of AES. It provides the strongest current encryption method.
WEP
Authentication
selects whether the encryption keys are matched (
1
= shared) with those
of the communication partner before passing through messages or not (
2
= open/none).
The
Encryption
prompt requests the length of the encryption key and the security
strength. WEP64 uses a 40 bits/5 bytes key (option
1
). WPE128 uses a 104 bits/13 bytes
key (option
2
).
Select
Y
(Yes) at the
Display current key
prompt to show the currently configured
key/passphrase.
Select
Y
(Yes) at the
Change key
prompt to be able to modify the currently configured
key.
The
Key type
indicates whether the new key is in hexadecimal or passphrase format.
Enter key
prompts for the new encryption key.
Key Type
Encryption Key
Hex
Enter
the
Encryption Key
as a hexadecimal value according the following
guidelines:
Valid Hex alphanumeric characters are 0-9 and A-F.
64 bit hex = 5 bytes represented as xx-xx-xx-xx-xx.
Example: 01-A3-47-E5-C9
128 bit hex = 13 bytes represented as xx-xx-xx-xx-xx-xx-xx-
xx-xx-xx-xx-xx-xx.
Example: A1-B2-C3-E4-D5-F6-98-74-B7-65-A8-D3-F2
Passphrase
Enter the key as a string. A passphrase is a sentence that is translated into
hex by a hashing algorithm.
Example: My dog has spots and likes to chase cats.
A passphrase of more than 20 characters is recommended. Maximum length
is 63 characters. Spaces and punctuation characters are permitted.
