Troubleshooting


If an operating problem occurs with the interface, check the following items.


If the LAN does not operate


• Is the cable properly connected?

→ Verify that the instrument is properly connected to the PC.
→ Use a cable with straight-through wiring when the instrument is connected to a hub.
→ Use a cable with crossover wiring when the instrument is connected directly to a 100BASE-TX interface on a computer.

• Is the IP address valid?

→ Refer to the preparation.

• Is the IP address of the instrument duplicated on another device?

→ Change the IP address.

• Is the power turned on?

→ Turn on all devices.

• Has the connection timed out?

→ When no communications occur for more than one hour, the communication link is automatically disconnected.
In this case, try to re-establish the connection.

• Is Error Response enabled?

→ When Error Response is enabled, the instrument returns ?Q, ?C, or ?E. Disable this function if you don't need these responses.


If data is improperly acquired when connecting to the instrument


• Does the PC read data immediately upon connection?

→ When establishing of LAN connection from the instrument to the PC, the instrument returns messages to indicate the success of the connection. Data should be read only after the connection messages have been received.
