Special care must be taken when replacing existing ACR ISA bus controller cards with an ACR8020 PCI bus controller card.
Although the P1A, P1B, P3, and P4 connectors are direct pin for pin replacements for the ACR8000 and ACR8010, the physical position of these connectors is different. The component placement on a PCI card is reverse that of an ISA card. This means the placement of the connectors is in the opposite order.
Please consult the hardware manuals for the ACR8020 and the hardware manual for the existing card to be sure the cabling is correct before applying power.
NOTE: Plugging in the incorrect cable can cause damage to the ACR8020 and the system components.
