Example: GPIB Interface Configuration
An I/O interface consists of a hardware interface and a
software interface. One purpose of the Connection Expert
utility is to associate a unique software interface ID with a
hardware interface. The Keysight IO Libraries Suite uses an
interface ID or logical unit number to identify an interface.
This information is passed in the parameter string of the
viOpen function call in a VISA program or in the iopen
function call in a SICL program.
For example, the GPIB interface system in
consists of a Windows PC with two 82351A GPIB cards
connected to three GPIB instruments via GPIB cables. For
this system, the Connection Expert utility has been used to
assign GPIB card #1 a VISA interface ID of "GPIB0" and a
SICL interface ID of "gpib0".
Connection Expert has also been used to assign GPIB card
#2 a VISA interface ID of "GPIB1" and a SICL interface ID
of "gpib1". With these names assigned to the interfaces, the
VISA/SICL addressing is as shown in
unique names have been assigned by Connection Expert, you
can use the VISA viOpen command to open the I/O paths to
the GPIB instruments. Or, you can use the SICL iopen
command to open the I/O paths shown.
