11. To resume normal configured operation when configuration is complete, switch the factory default DIP
switch on the 245U-E to RUN and cycle power.
NOTE Security Certificates. Configuration of the 245U-E uses an encrypted link (https). The security
certificate used by the 245U-E is issued by ELPRO and matches the IP address 192.168.0.100.
When you first connect to the 245U-E, your Web browser will issue a warning that ELPRO is not a
trusted authority. Ignore this warning and proceed to the Configuration webpage. To avoid seeing this
warning in the future, you can install the certificate into your browser.
Internet Explorer 7 has an additional address check on security certificates. Unless the 245U-E has the
address 192.168.0.100, when you first connect to the 245U-E Internet Explorer 7 will issue a warning
about mismatched security certificate address. You can turn off this behavior in IE7 by selecting:
Tools > Internet Options > Advanced > Security > Warn about certificate address mismatch
Method 2 – Set 245U-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
245U-E so that it appears on your network. Ask your system administrator if you do not know the correct
settings for your network. The default IP address of the 245U-E modem is 192.168.0.1, and the network
you wish to connect to is on 10.10.0.X (the PC is on 10.10.0.5).
Once you have determined the correct settings for your network, you need to connect to the modem’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.
1. Open HyperTerminal and monitor communications.
2. Set the SETUP/RUN switch to the SETUP position, and connect power to the modem.
3. Observe HyperTerminal and when you see the ELPRO Dragon screen (see below) press Enter to get the
following prompt “#.”
4. Type the following “ifconfig” command to show the configuration of the Ethernet port. From this you
will see what the IP address is.
