Note
You also can use VXI Interactive Control Program (VIC) to control the VXI/VME
devices and develop and debug VXI application programs. VIC is not included in the
default NI-VXI installation; to install it, select
NI-VXI API Development
from the
custom installation screen in the installer.
You can launch VISAIC (or VIC) from the Tools menu in MAX or from the
VISA or VXI subgroups in
Start»Programs»National Instruments
.
Try the following in VISAIC: In the tree view, navigate using your mouse
to the VISA resource for your controller—probably
VXI0::0::INSTR
,
representing the VXI system 0, logical address 0 instrument resource (refer
to Figure 3-2).
Figure 3-2.
Select Your Controller in VISAIC
Open the selected resource and navigate to the Register I/O tab. In this tab,
you can read registers on the device, such as the VXI device configuration
registers. Execute the
viIn
operation (called
In
in LabVIEW compatibility
mode) with the default parameters. The Data Value field shows the I/O
operation result, such as
0x9ff6
. The Return Value field shows the
function status, such as
0
for
VI_SUCCESS
. This dialog box may look
slightly different for LabVIEW users. Refer to Figure 3-3.
