LAN Communication Failure
Problem:
Connection Expert cannot successfully verify a device connected via LAN (Ethernet).
Probable Cause:
There are several possible causes for this failure. They fall into two categories:
- Physical connectivity failure.
- Configuration problems involving the instrument, the network, or Connection Expert
Suggested Steps:
Check the physical connection to your instrument. Ensure that your PC is connected to the LAN; that the instrument is also connected to the LAN; and that the instrument is turned on.
Check the network connectivity by using a command outside of Connection Expert, such as ping <instrument_ip_address> or ping <instrument_hostname>. If this fails, the problem relates to your network or to the instrument's configuration. Consult your instrument's documentation and your IT department to resolve such problems.
If the ping is successful, you may have a problem involving the configuration of the interface or instrument in Connection Expert. This procedure only applies to manually-added instruments — not auto-discovered instruments.
- Select the instrument in question, and make sure the hostname or IP address is correct.
- Click the
icon.
- Examine the remote instrument name. Consult Sample Remote Names for Interfaces and consult your instrument's documentation to ensure you are using the correct remote name.
- In the list of devices on the left, select the LAN interface (for example, TCPIP0). Ensure that the selected default protocol is supported by your instrument, or try setting the default protocol to Auto.
- Examine the timeout values. You may need to increase the timeouts to work with your instrument or network configuration.
