ACCESSORIES
The Compact UMAC Turbo CPU board is always used with accessory boards. Delta Tau provides
several accessory boards in the Compact UMAC family that can be used with the CPU board; other
parties may produce accessory boards as well. Each accessory board has its own hardware reference
manual.
Acc-Cx Compact UBUS Backplane Boards
The Acc-Cx family of Compact UBUS backplane boards
provides the means for the CPU board to communicate with
other accessory boards. The x in the name of the backplane
board refers to the number of backplane data slots provided.
