Note: Twenty-four bits in the encryption key are factory preset and not modifiable.
A 64-bit encryption key can be represented by ten (10) hexadecimal digits. For a
128-bit encryption key, twenty-six (26) hexadecimal digits need to be provided. For
a 152-bit encryption key, thirty-two (32) hexadecimal digits need to be provided.
Note: Hexadecimal digits are the first ten numbers of the decimal system (0, 1, 2,
3, 4, 5, 6, 7, 8, and 9) and the letters A, B, C, D, E, and F. Your choice of characters
is arbitrary. You might use, for example, a phone number. (Do not use an obvious
one, such as your office phone number). The table below shows you some
examples of encryption settings.

Key Size (64, 128, or 152 bits): ___________________

What is the SSID for your wireless network?
The Service Set Identification (SSID) is an alphanumeric character string identifying the
wireless local area network. The HA501 Wireless Adapter can only communicate with wireless
NICs or access points configured with the same SSID. For the access point and wireless nodes
to communicate with each other, all must be configured with the same SSID. Either the SSID
for your wireless network was assigned in a preexisting wireless network or, if there was no
preexisting wireless network, you must create the SSID just as you would create a network
name, using from 1 to 32 characters and not including any spaces or hyphens between characters.
SSID: _________________________________________
Which wireless channel to use?
When the HA501 Wireless Adapter is configured to operate in Infrastructure mode, it auto-
matically scans through all eight available channels (three when in turbo mode) for the closest
access point to associate with. When the HA501 Wireless Adapter is configured to operate in
ad-hoc mode, one of the HA501 Wireless Adapters will automatically operate as a virtual access
point. There is no need to set up the wireless channel for the wireless adapter.
What is the WEP Encryption key?
The absence of a physical connection between nodes makes the wireless links vulnerable to
information theft. To provide a certain level of security from eavesdroppers and hackers, you
can (1) enable WEP encryption and (2) create your shared key in the security table of the
configuration utility. The HA501 Wireless Adapter supports “shared key” encryption with key
sizes from the industry standard 64-bit, 128-bit and 152-bit.
The Shared Key, as well as the key content used by the HA501 Wireless Adapter and the wire-
less access point or other wireless nodes in the same network, must be the same.
