LAN troubleshooting suggestions
If you are unable to connect to the instrument's web interface, check the following items:
• Verify that the network cable is in the LAN port, not one of the TSP-Link
®
ports (see the
description in 5. LAN
(on page 2-6)).
• Verify that the network cable is in the correct port on the computer. The side LAN port of a laptop
may be disabled while the unit is in a docking station.
• Verify that the correct Ethernet card's configuration information was used during the setup
procedure.
• Verify that the computer's network card is enabled.
• Verify the instrument's IP address is compatible with the IP address on the computer.
• Verify the instrument's subnet mask address is the same as the computer's subnet mask
address.
• Turn the instrument's power off, and then on.
• Restart your computer.
• Contact your system administrator for assistance.
