Configuring I/O Interfaces
Configuring VXI Interfaces
Configuring VXI (E8491B) Interfaces
An IO interface can be defined as both a hardware interface and as a
software interface. The purpose of the IO Config utility is to associate a
unique interface name with a hardware interface.
The IO Libraries use an
Interface Name 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. IO Config assigns an Interface Name and Logical Unit Number to
the interface hardware, as well as other necessary configuration values for
an interface when the interface is configured.
Using IO Config to
Configure VXI
(E8491B) Interfaces
To configure VXI (E8491B module) interfaces using the IO Config utility,
click the Agilent IO Libraries Control icon (blue icon on the Windows taskbar)
and click Run I
O Config. When the main screen appears, highlight the
VXI E8491 IEEE-1394 to VXI menu item (see the following figure)
and click the C
onfigure button.
