Introduction to IO	An IO interface consists of a hardware interface and a software interface.
Interface	One purpose of the Connection Expert utility is to associate a unique
Configuration	software interface ID with a hardware interface.
	The Agilent 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.
	Connection Expert assigns an Interface ID and Logical Unit (LU) Number to
	the interface hardware, as well as other necessary configuration values for
	an interface when the interface is configured. Typically, the LU Number is
	automatically assigned and you can ignore its setting. The LU Number is
	used internally as a unique identifier. When the IO interface is configured,
	you can use Agilent VISA, VISA COM, or SICL to program assigned
	instruments.
Example: IO	For example, the GPIB interface system in the following figure consists of
Interface	a Windows PC with an 82357A USB/GPIB Interface Converter connected
Configuration	between a USB port and three GPIB instruments with GPIB primary
	addresses of 3, 4, and 5, respectively. The instruments are connected via
	GPIB cables.
	For this system, the Connection Expert utility has been used to assign a
	VISA name of “GPIB1” and a SICL name of “hpib7”. With these names
	assigned to the interfaces, the VISA/SICL addressing is as shown in the
	figure.
	Since unique names have been assigned by Connection Expert, you can
	use the VISA viOpen command to open the IO paths to the GPIB
	instruments as shown in the figure. Or, you can use the SICL iopen
	command to open the IO paths.
