Radio Interface
IP Address
The IP address of the E2 on its wired (Ethernet Interface) port
and wireless (Wireless Interface) port. This should be set to
the IP address you require. If the device mode is set to
bridge, then the wired and wireless ports will have the same
IP address.
IP Subnet Mask
The IP network mask of the E2 on its wired (Ethernet
Interface) port and wireless (Wireless Interface) port. This
should be set to appropriate subnet mask for your system
(Typically 255.255.255.0).
Save Changes
Save changes to non-volatile memory. The module will need
to be restarted before the changes take effect.
Save Changes and
Reset.
Save settings to non-volatile memory, and reboot E2. Once
the module has completed the reboot sequence, all changes
are in effect.
4.3 Radio Settings
The E2 can be configured for different radio transmission rates. A reduction in rate
increases the reliable range (transmission distance). The factory-default data rate
settings are suitable for the majority of applications and should only be modified by
experienced users.
The E2 allows for configurable fixed or fallback radio transmission Data Rates. When a
fixed rate is configured, the radio transmission rate is never altered, even under
extremely poor conditions. The fallback rates allow a maximum rate to be configured
whilst enabling the unit to automatically reduce the rate when transmit errors occur.
When a radio transmission is unsuccessful, the E2 will automatically drop to the next
lowest data rate and enter probation. If subsequent transmissions are successful at the
lower rate, the E2 will attempt to increase to the next highest rate when probation has
ended. When a station connects to an access point the two devices negotiate a data
rate based which is within configured range of radio data rates for both devices. If there
is no common data rate, then the devices will not be able to connect.
Select the “Radio” Menu to change the following configuration parameters. If a change
is made, you need to select “Save Changes” to retain the changes. Changes will not
take effect until the unit is reset.
