4.4 Factory Default Switch
When powered up with the Factory Default switch on, the 905U-E will start with temporary
settings of ethernet IP address 192.168.123.123, subnet mask 255.255.255.0, gateway IP
192.168.123.1, username and password “user” and the radio disabled. This allows easy access to
configuration when configuration detail has been forgotten. The existing configuration is not
modified, unless the user makes changes.
Do not forget to set the switch back to the OFF position and cycle power at the conclusion of
configuration for resumption of normal operation.
4.4 Configuration Program
The 905U-E has a built-in webserver, containing webpages for analysis and modification of
configuration. The configuration must be accessed using Microsoft® Internet Explorer. This
program is shipped with Microsoft Windows or may be obtained freely via the Microsoft®
website on the internet.
Serial configuration for IP address, gateway address and subnet mask may be accessed via the
RS-232 serial port.
Accessing Configuration inside a module for the first time
There are two methods for accessing the configuration inside a 905U-E. The first method
requires changing your computer settings so that the configuring PC is on the same network as
the 905U-E with factory default settings.The second method requires setting an IP address so the
905U-E is accessable on your network.
You will need a straight through ethernet cable between the PC ethernet card and the 905U-E.
The factory default ethernet address for the 905U-E is 192.168.123.123.
Consult your network administrator for an IP address on your network, the gateway IP address,
and network mask.
Adjust PC or 905U-E network settings so that both are on the same network. This may achieved
two ways as outlined below.
Option 1 – Set PC to same network as 905U-E
Connect ethernet cable between unit and the PC configuring the module.
Set the Factory Default Switch to the ON (SETUP) position. This will always start the
905U-E with ethernet IP address 192.168.123.123, subnet mask 255.255.255.0,
gateway IP 192.168.123.1 and the radio disabled. Do not forget to set the switch
back to the OFF position and cycle power at the conclusion of configuration for
resumption of normal operation.
