7.2 Troubleshooting the Web Interface
These troubleshooting hints assume that the status LEDs on the front panel of the
terminal displays normal functionality.
Table 31: Web Interface Diagnostics
Symptom Possible
Problem Solution
Incorrect IP
address and/or
Subnet Mask. Perform a ping test from the host computer
command line.
If the ping test is unsuccessful, then the problem
is with the IP address. Perform a long reset to
apply the default address (192.168.25.2) and
Subnet Mask (255.255.255.0)
Problems with
host computer, or
terminal. If the ping is successful try a short reset of the
terminal, and/or reboot the host computer.

Information)

Host PC ARP
table is
incorrectly
configured Run the command 'arp: -d' whenever the terminal
is swapped. Check that the subnet mask for the
host PC matches the subnet mask of the
terminal. Check that the host PCs address is
192.168.25.n, where n is not equal to 0,2, or 255.
Attempt to login to the terminal using a Web browser. Microsoft Internet Explorer is
recommended. If the terminal 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.
The next test is to verify the IP address is reachable from the computer. Use the ping
command to test the connection between the terminal and host computer. The system
always responds to ping frames less that 577 bytes in length.
>Ping 192.168.25.2
If the ping test is successful, the host computer was able to send and receive packets
to/from the terminal. The problem may be with the Internet browser or related
settings on the host computer. Re-boot 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 terminal must appear to be on the same subnet. For
example, if the terminal 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 terminal cannot be determined, it is recommended to
perform a long reset to restore the terminal to the default value.
Warning: Performing a long reset restores the terminal IP address (192.168.25.2)
and IP Subnet Mask (255.255.255.0) to the factory default value.
