Common Questions
This appendix addresses common questions you may have about using the
NI-VISA/NI-VXI software with the VXI-8340 series.
I need more devices than can fit in one chassis. How can I expand my
VXI-8340 series system?
There are two ways to expand your system beyond a single chassis:
•
You can add additional VXI-8340 series controllers, either by
daisy-chaining through a dual-port VXI-8340 or by adding another
single-port VXI-8340 kit (PCI-8330 and single-port VXI-8340).
•
If you need all your VXI devices to appear as if they are part of the
same VXI system (that is, they share an address space, interrupts,
and triggers), VXI-MXI-2 allows you to add more chassis to your
system. VXI-MXI-2 extends full VXI functionality across multiple
mainframes in accordance with the VXI-6 specification. Place a
VXI-MXI-2 in the same frame as the Slot 0 VXI-8340 controller, and
another VXI-MXI-2 in Slot 0 of the mainframe you want to add to the
system. You can then fill up this mainframe with additional devices.
How can I determine the serial number and hardware revision of the
VXI-8340 series module?
Run MAX and right-click on the name of the VXI-8340 series module.
Select
Hardware Configuration
, and the dialog box for the VXI-8340
series module is displayed. The title bar includes the serial number and
hardware revision of the module.
What is Resman?
Resman is the utility that performs the duties of a VXI Resource
Manager as discussed in the VXIbus specification. When you set a
National Instruments controller to Logical Address 0, you will at
some point need to run Resman to configure your VXI instruments.
If your controller uses a different (non-zero) logical address and is a
message-based device, you need to start Resman before running it on
the Logical Address 0 computer.
