workstations on a basis other than geographic location.

Network Name (SSID)
This string, (32 characters or less) is the name associated with the AP. To
connect to the AP, the SSID on a Station card must match the SSID on the
AP card or be set to “ANY.”
Channel
The AP transmits and receives data on this channel. The number of channels
to choose from is pre-programmed into the AP card. Station cards do not
have to be set to the same channel as the AP; the Stations scan all channels,
and look for an AP to connect to.
WEP Security
WEP (Wired Equivalent Privacy)
The AP card supports 64-bit, 128-bit, or 256-bit WEP encryption. The WEP
option can also be disabled. If so, any station can connect to the AP (as long
as its SSID matches the AP SSID).
text only WEP Key
If selected, the WEP Key is treated as a string of text characters, and the
number of characters must be either 5 (for 64-bit encryption) or 13 (for 128-
bit encryption) or 29 (for 256-bit encryption). If not selected, the WEP key is
treated as a string of hexadecimal characters, and the number of characters
must be either 10 (for 64-bit encryption), 26 (for 128-bit encryption), or 58
(for 256-bit encryption). The only allowable hexadecimal characters are 0-9
and A-F.
NOTE: The WEP key must be the same value and type for both VersaLink
and the wireless network adapter. “Pass Phrase” is not the same as “text” and
should not be used.
Enhanced Security
If selected, the SSID is hidden from detection in certain frames of the radio
protocol. This makes the SSID harder to discover by external equipment
capable of passively scanning the radio signal. Additionally, the station SSID
must match the AP Network Name (SSID); the generic station SSID, “ANY”
