4. For VXI systems that include VME devices, ensure that the VME
devices are not configured in the upper 16 KB (starting from 0xC000)
of the A16 address space. This region is reserved for VXI device
configuration registers, which are used for initializing, configuring,
and interacting with VXI devices.
Note Also ensure that no other VXI devices in your system are configured for logical
address 0. This is the default configuration for the VXI-8340 series.
Connect the Cable
Connect the MXI-3 cable to the PCI-8330 series and the MXI IN port of the
VXI-8340 series, as shown in Figure 2-1.
Power on the System
1. Be sure the MXI-3 cable is connected securely.
2. Turn on the VXI chassis.
Note Always power on the VXI-8340 series at least 8 seconds before your PC. Refer to
Appendix D, Power Sequencing Requirements , for more information regarding power-up
requirements for the VXI-8340 series controllers.
3. Turn on the host computer.
4. If your system CMOS setup requires you to adjust PCI bus parameters,
do so at this time.
Note The PCI bus usually assigns IRQs and port addresses automatically. However, in
some PC systems, you may need to edit the PCI bus parameters manually in your CMOS
setup. Some older PCs also require bus mastering to be enabled. Refer to your computer
documentation for further instructions.
