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, 

) on the front 

panel of your VXI-USB controller indicates your connection speed.

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, 

.

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.
