Conguring and Establishing a LAN Connection
Troubleshooting LAN connections
Are the cables connected properly?
• There may be a faulty contact in the connector. Disconnect and reconnect the cable.
• The LINK LED on the instrument’s LAN connector will light up once a connection has been
established.
Has the computer’s IP address been set properly?
• Check the IP address, subnet mask, and gateway address set for the computer’s network
interface.

Can the instrument and computer communicate?
• If the instrument and computer’s IP addresses have been set properly, you can check whether
the computer can communicate with the instrument using the ping protocol.

wish to verify) and press the ENTER key.
If an IP address can be obtained from the hostname using DNS, you may also enter the
hostname.
For example, if the instrument’s IP address is 192.168.1.2, enter ping 192.168.1.2.
