Appendix D Common Questions
VXI-USB User Manual D-2 ni.com
How can I determine the serial number and firmware version of the
VXI-USB module?
This information is displayed in the title bar of the Hardware Configuration
window in MAX.
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 (nonzero) logical address and is a message-based device, you need
to start Resman before running it on the Logical Address 0 computer. The
VXI-USB is always logical address 0.
When do I need to run Resman?
Run Resman whenever you need to configure your VXI instruments (for
example, when you power cycle either the host computer or the chassis).
You do not need to run Resman if you unplug your USB cable from the host
and plug it in again without power cycling either the chassis or the host
computer.
Which NI-VXI utility program must I use to configure the VXI-USB?
Use MAX to configure the VXI-USB. MAX is in the
National
Instruments
program group folder, and a shortcut is on your desktop.
How do I handle VME devices?
Although there is no way to automatically detect VME devices in a system,
you can add them easily through the Add Device Wizard in MAX. Through
this procedure, you can reserve resources for each of your VME devices
and configure MAX to show VME devices on the screen with all your other
devices.
Which NI-VXI utility program must I use to perform startup Resource
Manager operations?
Use the Resman program to perform startup Resource Manager operations
in Start»Programs»National Instruments»VXI. Resman uses the
settings configured in MAX. It initializes your VXI/VMEbus system and
makes the information it collects accessible through MAX. You can also
run Resource Manager operations from MAX. Through MAX, you can also
configure Resman to run automatically at startup.
