Can I use multiple PCMCIA cards in one computer?
Yes, but make sure there are enough free resources available. Unlike PCI
or PXI CAN cards, PCMCIA CAN cards cannot share resources, such as
IRQs, with other devices.
I have problems with my NI PCMCIA CAN card under Windows NT.
How can I resolve them?
Windows NT offers minimal support for plug and play and there are several
things to consider.
Because Windows NT does not automatically assign resources to PCMCIA
cards, the PCMCIA CAN cards are configured to use default values for the
IRQ and the memory range. If those resources are already in use by other
devices, it might be necessary to manually change those values.
To do so, right-click the PCMCIA CAN card in MAX and choose
Properties. Assign resource values that do not conflict with other device
resources for either the Interrupt Request (IRQ) or the Memory Range.
Initially, all NI PCMCIA CAN cards will have the same resources
assigned. If you have more than one PCMCIA CAN card installed, the Self
Test will fail. You must change the resources of one of the cards manually.
Windows NT does not allow more than one PCMCIA card of the same type
installed. Thus, you cannot use two NI PCMCIA cards in the same system.
Why are some components left after the NI-DNET software is
uninstalled?
The uninstall program removes only items that the installation program
installed. If you add anything to a directory that was created by the
installation program, the uninstall program does not delete that directory,
because the directory is not empty after the uninstallation. You must
remove any remaining components yourself.
