KPXI-CON-PXIREM supports 64-bit or 32-bit PCI buses operating at 66MHz or 33MHz. A bundled
link can support the full bandwidth of 64-bit/66MHz PCI bus. You can utilize the following
configuration to set the operation frequency of your system.
KPXI-CON-PCIREM/KPXI-CON-PXIREM supports the following primary and secondary bus
frequency combinations:
1. 66MHz primary bus, 66MHz secondary bus
2. 66MHz primary bus, 33MHz secondary bus
3. 33MHz primary bus, 33MHz secondary bus
KPXI-CON-PCIREM/KPXI-CON-PXIREM does not support 33MHz primary/66MHz secondary bus
operation.
Installing KPXI-CON-PCIREM
Follow these steps to install KPXI-CON-PCIREM:
Step 1:
Turn off your computer, leave it plugged in while installing KPXI-CON-PCIREM. The power
code grounds the chassis and protects it from electrical damage while you install this
module.
Step 2:
Remove the top cover and the access port to the PCI bus.
Step 3:
Select any available PCI slot and remove the bracket-retaining screw.
Step 4:
Plug in the KPXI-CON-PCIREM and reinstall the bracket-retaining screw.
Step 5:

66 MHz PCI enable. If the backplane or any devices in the
system do not support 66MHz PCI bus operations, extension
modules will detect the configuration and operate at 33 MHz
automatically.
