6.1
Interface Connection Issues
Attempt to login to the RDL-3000 using a Web browser. Microsoft Internet Explorer is
recommended. If the RDL-3000 does not respond by displaying the login dialog box,
check that the correct IP address is being used. The value 192.168.25.2 is the factory
default value and may have been changed during installation.
Test is to verify the IP address is reachable from the computer. Use the ping command
to test the Service between the RDL-3000 and host computer.
>ping 192.168.25.2
If the ping test is successful, the host computer was able to send and receive packets
to/from the RDL-3000. The problem may be with the Internet browser or related settings
on the host computer. Reboot the host computer to try to resolve the problem.
If the ping is unsuccessful, there may be problems using that IP address; the IP address
may be incorrect, or there may be a duplicate address. For correct operation the host
computer and the RDL-3000 must be on the same subnet. For example, if the RDL-3000
is using the factory default settings, the host computer could be set for an IP of
192.168.25.3 and a subnet mask of 255.255.255.0.
If the correct IP address of the RDL-3000 cannot be determined, it is recommended to
perform a Long Reset operation. refer to section 6.5: Long Reset (Recover from Lost
Password or IP) on page 123. The following table lists some common troubleshooting
tips for the web interface.
