Troubleshooting
Remote network users are unable to contact the unit

Check that the correct address is being used by the remote users.

Check the network settings. Check that the user’ network address has not been
excluded in the IP access control section.

If the UltraLink-2 is situated behind a firewall, check that the relevant ports are
being allowed through the firewall and are being correctly routed.

Check the front panel indicators, the LNK indicator should be on. If the network link
is a 100Mbps connection, the 100 indicator should also be on.
Remote IP address is locked out (Blacklisted)

If the remote user logged on incorrectly five times using the VNC Viewer, try logging
on using the Applet. If logging on using the Applet is successful, the IP address will
be unlocked.

If the remote user logged on incorrectly five times using the Applet, try logging on
using the VNC Viewer. If logging on using the VNC Viewer is successful, the IP
address will be unlocked.

If both the VNC viewer and Applet login is denied access, remove power from the
UltraLink 2 for two to three seconds. This will reset the unit and unlock the IP
address. If the UltraLink2 unit is using DHCP, the previously assigned IP address
may be changed to a different IP address when power is restored. Remote users
will need to be informed of the new IP address. If you still have problems with a
Blacklisted IP address, please contact Rose Electronics technical support.

Either, the VNC viewer is an old version or only the admin user has been
