The new design is 100% backward compatible with
the older revisions in terms of:
• Operation with both the UMAC Turbo CPU and MACRO CPU
• Addressing with both the UMAC Turbo CPU and MACRO CPU
• Field wiring connections to Encoders, Amplifers, TUVW, Flags,
and EQU outputs
One of the major changes to the card designs is the placement connection
of the piggy back 2-axis expansion card to the baseboard of the
ACC24E2A or ACC24E2. The older revision piggy back 2-axis expansion
cards will not be compatible with the new baseboard design of the
newer revision because this connection has been moved for improved
signal quality. Likewise the new revision piggy back 2-axis expansion
cards will not be compatible with the older revision baseboard of
the ACC-24E2A and ACC-24E2.
The new revision of the ACC-24E2A has 603398-104 (rev4) designation.
The new revision of the ACC-24E2 has the 603398-104 (rev4) designation.
