Hardware Address Limitations
The ACC-11E has a hardware address limitation relative to the newer series of UMAC high-
speed IO cards. The new IO cards have four addresses per chip select (CS10, CS12, CS14, and
CS16). This enables these cards to have up to 16 different addresses. The ACC-9E, ACC-10E,
ACC-11E, and ACC-12E all have one address per chip select but also have the low-byte, middle-
byte, and high-byte type of addressing scheme and allows for a maximum of twelve of these IO
cards.

Addressing Conflicts
When just using only the type A UMAC cards or using only the type B UMAC cards in an
application, the user does not have to worry about potential addressing conflicts other than
making sure the individual cards are set to the addresses as specified in the manual.
If the user has both type A and type B UMAC cards in their rack they should be aware of the
possible addressing conflicts. If the customer is using the Type A card on a particular Chip Select
(CS10, CS12, CS14, or CS16) then they cannot use a Type B card with the same Chip Select
