4 Troubleshooting the E5810B
Checking PC Client Connection
100 E5810B User’s Guide
E5810B appears to be hung There are several possible causes. For all of the following, use of client
timeouts and/or E5810B timeouts (the I/O timeout and LAN timeout
configuration values) can be used to ensure that the E5810B will not stall
indefinitely.
• If you determine that the E5810B 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 E5810B to proceed. Otherwise, you
can select the Clear ALL Pending Operations button on the Find and
Control Instruments Connected to your E5810B Web page or you can
reboot the E5810B.
• The network connection to the E5810B has been broken.
• The E5810B 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 E5810B 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 selecting the Session Status tab to display the E5810B
LAN/GPIB/USB Gateway Status Web page.
