50 Operation Theory
4.7 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 IRQ setting of the card are automatically assigned by
the PCI BIOS at the beginning of system booting. Users don’t
need and can’t change the resource settings.
When multiple cards are applied to a system, the number of card
must be noted. The card number depends on the card ID switch
setting on the the board. The axis number is depends 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:
Notice that if there has the same card ID on multiple cards, the
function will not work correctly.
