Annie CrateArchitecture• Double Width ACM:

One ACM Card can service 8 ACCs. System can be extended in multiples of 8, in a pyramid scheme.

• Single Width ACM:One ACM Card can service 4 ACCs. System can be extended in multiples of 4, in a pyramid scheme.

• New ACM can be designed to service up to 16 ACCs.
