80 Operation Theory
4.9 Multiple Card Operation
The motion controller allows more than one card in one system.
Since the motion controller is plug-and-play compatible, the base
address and the IRQ setting of the card are automatically
assigned by the PCI BIOS during system startup. Users don’t
need and can’t change the resource settings.
When multiple cards are applied to a system, the number of cards
must be noted. The card number depends on the card ID switch
setting on the board. The axis number is dependant on the card
ID. For example, if three motion controller cards are plugged in to
PCI slots, and the corresponding card ID is set, then the axis num-
ber on each card will be:
Axis No.
Notice that if multiple cards have the same card ID the function will
not work correctly.
