Configuring a Wireless Module (Continued)
This information explains the various configuration options available. Continue with
the wireless SeaI/O configuration on the following page.
The Network SSID (Service Set Identifier) is the name of the wireless network. The
SSID can be up to 32 alphanumeric characters and is case-sensitive. If you are using
the wireless SeaI/O module with a wireless access point (WAP), then the SSID
names must match.
The network Topology defaults to Ad Hoc mode and supports Infrastructure mode.
Ad Hoc mode is a point-to-point method used to communicate with other wireless
network clients, including laptop computers and desktop computers using a wireless
adapter. If you are using a WAP, select Infrastructure mode.
The network Channel will vary depending on the number of times the wireless
SeaI/O module is reset. Every time the wireless SeaI/O module is reset, the channel
will increment up by one. Since the wireless SeaI/O module supports channels 1-14,
there is a chance that a reset can put the wireless SeaI/O module on a channel not
compatible with your wireless adapter or access point. If you cannot see the wireless
SeaI/O module on your network, try resetting the module using the steps described at
the beginning of this section. Depending on the country used, it may take several
reset cycles to get the unit back to a channel valid for your region. Use the Wireless
Configuration window to change channels, if possible.
The Key Encoding method can be either a Passphrase or a Hexadecimal Key, if
using a WEP variant. If you are using a WPA variant, then the Key Encoding
method is Passphrase.
Different security encryption methods require different Network Key types and
lengths. The different key types and lengths are displayed below:
WEP 64-bit 10 character hexadecimal key or up to 32 character passphrase
WEP 128-bit 26 character hexadecimal key or up to 32 character passphrase
WPA up to 64 character passphrase
WPA2 up to 64 character passphrase
