The GPIB Address String
When programming the L4411A over GPIB, the instrument’s GPIB address is
included in the address string as shown below:
GPIB0::

::INSTR
The Web-Enabled Instrument Interface and Interactive IO
The Web-enabled instrument interface
is not
available from the GPIB inter-
face. (Note the “Instrument Web Interface” link that is missing from the ‘prop-
erties pane’ in Figure 2-12 compared to Figure 2-7 (LAN interface).)
The Connection Expert ‘Interactive IO’ utility can be used to send SCPI com-
mands from the L4411A command set to the instrument. See the section
“Using Interactive IO”
for more information.
Changing the GPIB Address
The L4411A GPIB address can only be changed programmatically. The com-
mand used to set the GPIB address is:
SYSTem:COMMunication:GPIB[:SELF]:ADDRess < address >
The command can be abbreviated by including only the upper-case letters in
the command syntax. Bracketed [] parameters are optional. The command can
be sent from the ‘Interactive IO’ window, or from the ‘SCPI Command Inter-
face’ window - via a LAN connection.
When the address is changed, the new GPIB address IS NOT updated in Con-
nection Expert if the instrument was previously configured.
From the Connection Expert window, highlight the instrument whose address
was changed and then select ‘Change Properties ...”. Within the configurable
properties window, change the address to the new address setting and select
‘OK’ (Figure 2-13).
