To resume normal configured operation when Configuration is complete, switch Factory Default dip-switch on the 450U-E
to RUN and cycle power.
Note: Security Certificates. Configuration of the 450U-E uses an encrypted link (https). The security certificate used by
the 450U-E is issued by ELPRO and matches the IP address 192.168.0.100.
When you first connect to the 450U-E, your web browser will issue a warning that ELPRO is not a trusted authority.
Ignore this warning and proceed to the configuration web page.
Internet Explorer 7 has an additional address check on security certificates. Unless the 450U-E has the address
192.168.0.100, when you first connect to the 450U-E, Internet Explorer 7 will issue a warning about mismatched security
certificate address. You can turn off this behaviour in IE7 by selecting
Method 2 - Set 450U-E Network address to match the local network
For this method you will need to determine what IP address, Gateway address, and Netmask to assign to the 450U-E so
rrect settings for your network.
E.g.
If the default IP address of the 450U-E modem is 192.168.0.1 and the network you wish to connect to is on 10.10.0.X
(PC is on 10.10.0.5)
Once you have determined the corre s RS-232 serial port
using a straight through serial cable and a terminal package such as HyperTerminal set to 115,200 baud. 8 data bits, 1
stop bit, no Parity.
Open HyperTerminal
Set the SETUP/RUN switch to the SETUP position, and connect power to the modem.
Observe HyperTerminal and when you see the Woody screen (see below) press <Enter> to get the following
ion of the Ethernet port and from this you will be able to
see what the IP address is, e.g.
Temporarily change the IP address to something that will enable connection to your local network. E.g type
fconfig eth0 10.10.0.6 Netmask only add the Netmask if the Netmask is anything other than the
standard 255.255.255.0
temporary and if the module is reset they will go back to the normal default (192.168.0.XXX).
