the command:
bip <Type the IP address>
i)
Switch dip-switch on WI-MOD-E to RUN position.
j)
Type the command
reset
, or cycle power to the unit. The WI-MOD-E will reset and start with
the network settings you have entered.
k)
Open Internet Explorer and ensure that settings will allow you to connect to the IP address
selected. If the PC uses a proxy server, ensure that Internet Explorer will bypass the Proxy
Server for local addresses. This option may be modified by opening Tools -> Internet Options -
> Connections Tab -> LAN Settings->Proxy Server -> bypass proxy for local addresses.
l)
Enter the webpage
http://xxx.xxx.xxx.xxx/
where
xxx.xxx.xxx.xxx
is the IP address selected for
the module. A welcome webpage should be displayed as illustrated.
m)
Clicking on any of the menu items, and entering the username “user” and password “user” may
open Configuration and Diagnostics. If the password has previously been configured other than
the default password, then enter this instead.

Network Configuration
You can view or modify Ethernet network parameters by selecting the “Network” menu. When
prompted for username and password, enter “user” as the username, and “user” as the password in
the password field. If IP address or password has been forgotten, the Factory Default switch may be
used to access the existing configuration. Refer to section 3.3 above.
The Network Configuration page allows configuration of parameters related to the wired and
wireless Ethernet interfaces. In general, IP address selection will be dependant upon the connected
wired Ethernet device(s) – before connecting to an existing LAN consult the network administrator.
A system of WI-MOD-E’s must have at least one Access Point acting as a master to one or more
Clients. All WI-MOD-E’s to be configured as part of the same wireless network should be given the
same System Address (SSID) and Radio Encryption settings. For further information and examples
on wireless network topologies refer section 1.1 above.
The WI-MOD-E supports several different radio encryption schemes. WEP (
Wired Equivalent
Privacy
) encryption is the weakest encryption method, defined by the original IEEE802.11 standard.
64bit and 128bit WEP combine either a 40bit or 104bit key with a 24bit initialization vector, and
are intended to provide equivalent security attributes to those of a wired medium. The WI-MOD-E
supports both 64bit and 128bit WEP without any performance (throughput) degradation.
WPA (
Wi-Fi Protected Access
) is a subset of the IEEE802.11i Security Enhancements specification.
The WI-MOD-E supports WPA-1 TKIP and WPA-2 AES using a
Pre-Shared Key
(PSK). TKIP
(
Temporal Key Integrity Protocol
) enhances WEP by using 128bit encryption plus separate 64bit Tx
and Rx MIC (
Message Integrity Check
) keys. Enabling TKIP will degrade the WI-MOD-E radio
throughput by approximately half of the rate attainable using either WEP or no encryption. AES
(
Advanced Encryption Standard
), the most secure encryption method, is also based on 128 bit
encryption key. Enabling AES in the WI-MOD-E will degrade radio throughput to approximately
20% of the rate attainable using either WEP or no encryption.
After changes are made to Network Configuration, it is important to save the configuration by
selecting “Save and Reset”.
