physical addresses for the:

’

s system memory—so the

card and the host computer can exchange data through the dual-port

interface. This is the base memory address.

•

host processor

’s I/O map—so the card’

s I/O devices can receive commands

from the host computer

. This is the

base I/O space addr

ess.

ou can have as many as four KTCX15 cards in one computer as long as each

card has dif

ferent base memory and base I/O space addresses.

in your computer must have a unique

base memory address and a

unique base I/O space memory address. If another card in the host

computer is using one or both of the factory-set addresses, you

must change a card’
