VXI-1394 Interface for Windows NT/98
Slot 0 VXI-1394, and another VXI-MXI-2 in Slot 0 of the next mainframe.
You can then fill up this mainframe with additional devices.
If you have additional GPIB devices to add to the system—such as a
GPIB-VXI/C controller in Slot 0 of another VXI chassis—the VXI-1394/G
comes with a built-in GPIB controller so that you can connect GPIB
devices directly off the VXI-1394/G without the need for a GPIB controller
in your host computer.
How can I determine the serial number and hardware revision of the
VXI-1394 board?
Run T&M Explorer and right-click on the name of the VXI-1394 board.
Select Hardware Configuration, and the dialog box for the VXI-1394
board is displayed. The title bar includes the serial number and hardware
revision of the board.
What is Resman?
Resman is the name of 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.
When do I need to run Resman?
Run Resman whenever you need to configure your VXI instruments. For
example, if you power-cycle your VXI chassis, your instruments will be
reset, and you will need to run Resman to configure them. You can get into
trouble if you run Resman when your devices are not in a reset state.
Therefore, if you have to run Resman after running it once, you should reset
all of your VXI instruments.
You can perform resource manager operations from within T&M Explorer
after you install the VXI-1394 and cable it to your computer. With the
VXI-1394, you may need to run the Resman utility if you boot your
computer before turning on your VXI chassis or if you power-cycle your
VXI chassis while the external PC remains on. In these cases, the
instruments would have been reset without the computer rebooting.
You will need to run the Resman utility or configure your system in T&M
Explorer to initialize your VXI system.
