Using E5810A Web Access
Finding and Querying Instruments
Finding Instruments
The Instruments Connected column of the page shows the GPIB and/or
RS-232 instruments connected to your E5810. This column shows the SICL
address for each instrument connected. The SICL address is required for
programmatically interacting with instruments via the E5810.
Using the Find
Button
To refresh the display or if instruments have been added/deleted, click the
Find button to display the current configuration. The Find command is
automatically run when the Find and Control Instruments Connected to your
E5810 page is opened and the correct password is provided. However, when
this page first opens, no instruments are displayed. Click the Find button to
display a current list of instruments that are powered up and connected to
the E5810.
After clicking the Find button, all GPIB equipment should appear in the box
below the button. In addition, the top item (" COM1,488 ") will always be listed
whether or not you have a RS-232 instrument connected. All other devices
shown in the
Instruments Connected list box are the SICL addresses of your
GPIB instruments. If no GPIB instruments are found, a message to this
effect is displayed in the output text (History) area.
Checking for
Connected
Instruments
After using the Find button, if you do not see one or more of your connected
GPIB instruments in the list, try these steps:
1 Check Cables. Make sure all GPIB instruments are connected via GPIB
cables to the E5810 GPIB port and the RS-232 instrument is connected
via an RS-232 cable to the E5810 RS-232 port.
2 Turn Instrument Power ON. Make sure power is turned on for all
instruments. Then, click the Find button at the bottom of the Instruments
Connected column.
3 Check Hardware. A broken GPIB instrument may short out the GPIB
cable and cause all instruments to show a failure. If you are
experiencing problems, try connecting only one GPIB instrument to the
E5810 at a time. Possible causes of the problem may be broken cable,
loose connectors, two or more instruments at the same GPIB address,
an instrument may be broken, or the E5810 may be broken.
4 Reboot the E5810. After checking hardware connections, reboot the
E5810 to do a self-test of E5810 hardware.
