Troubleshooting Information
Checking PC Client Connections
E5810 appears
to be hung
There are several possible causes. For all of the following, use of client
timeouts and/or E5810 timeouts (the I/O timeout and LAN timeout
configuration values) can be used to ensure that the E5810 will not
“hang” indefinitely.
If you determine that the E5810 is truly hung, you may be able to
free it by terminating a particular client connection at the client,
thus freeing the resources to allow the E5810 to proceed.
Otherwise, you can press the
Clear ALL Pending Operations
button on the
Find and Control Instruments Connected to your
E5810
Web page or you can reboot the E5810.
The network connection to the E5810 has been broken.
The E5810 may be attempting a transaction to a non-existent or
powered-off device. Check the address used, as well as the
status of the device.
The E5810 is busy performing a very long transaction to a (slow)
device, or it is waiting for input from a device.
A client may be waiting for access to a device/interface locked by
another client. Check for possible deadlock situations and, if
possible, make sure the clients owning locks and the connections
to those clients are still up and functioning. You can check the
current session by clicking the
Session Status icon to display the
E5810 LAN/GPIB Gateway Status Web page.
