performance. Plug-in boards with USB 2.0 ports are also supported but may not provide
the highest performance. Full-speed (USB 1.x) ports are supported as well, but provide
much lower performance. The LINK light (refer to Chapter 1, Introduction) on the front
panel of your VXI-USB controller indicates your connection speed.
Software Configuration and Verification
To configure the software and verify the configuration, follow these steps:
1. Run MAX. You must run the Resource Manager (Resman) every time
the chassis or computer power is cycled, so that your application can
access devices in the VXI chassis. You can also configure MAX to run
Resman automatically at every computer startup by selecting
Tools»NI-VXI»VXI Options and selecting the appropriate checkbox.
2. You can also use MAX to interactively configure the National
Instruments hardware in your system. Use the right-click help for
information about the various configuration options. After you finish
configuring the system through MAX, verify the configuration
through the interactive control utility, VISAIC (Start»Programs»
National Instruments»VISA»VISA Interactive Control), as
described in Chapter 3, Developing Your Application.
Note If you are using extenders such as MXI-2 to create a multichassis system, you may
need to run Resman before configuring some of your devices. Also, if you are using
multiple VXI-USB controllers to create a multisystem configuration, you configure each
system separately.
