If you know or suspect that something has changed on your network,
consult with your network administrator.
Timeout Errors Timeout errors such as "Device Timeout," "File
Timeout," and "Operation Timeout," are symptoms of one or both of
the following problems:
— The currently configured timeout limits are too short compared to
— The LAN connection has failed, or fails occasionally.
To increase your timeout period, refer to your computer
documentation for instructions. Contact your LAN administrator if
problems continue.
Packets Routinely Lost If packets are routinely lost, proceed to the
troubleshooting section in this chapter relating to your network.
Problems Transferring or Copying Files If you have problems
copying files out of or into the instrument, you might be experiencing
timeout problems. See the previous section on "Timeout Errors."
Common Problems After a Connection is Made
This section describes common problems you may encounter when
using the instrument on a LAN. It assumes you have been able to
connect to the instrument in the past. If this is not so, refer to the
previous sections first.

NOTE
Remember that in any type of programming using LAN you should
avoid constantly opening and closing connections. This uses up
processing resources, adds to your system overhead, and can cause
problems with asynchronous implementation of successive commands.
When you are sending the instrument multiple commands: open the
connection, send all the commands, and close the connection.
Cannot connect to the analyzer
• If you suspect a bad LAN connection between your computer and
instrument, you can verify the network connection by using the ping
command described later in this chapter or another similar echo
request utility.
• If a bad connection is revealed, try the following solutions:
— Make sure the instrument is turned on.
