ACCESSORIES
The UMAC-CPCI Turbo CPU board is always used with accessory boards. Delta Tau provides several
accessory boards in the UMAC-CPCI 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.
This picture shows an ACC-C8 8-slot backplane board. It has
a P47-style power connector suitable for a standard 1-slot
CPCI-format power supply.
ACC-8CR Test Breakout Board
The ACC-8CR board provides a behind-the-backplane breakout scheme for the J2 field wiring connector
on any of the 3U-format UMAC-CPCI board. It is designed to plug into the rear of an ACC-Cx Compact
UBUS backplane board, and it meets the Compact PCI physical specification (100mm x 80mm) for rear
distribution boards. It has 110 screw-down terminal points, one for each signal on the J2 field wiring
connector.
ACC-11C Sinking I/O Board
The ACC-11C board provides 32 isolated 12V-24V
sinking inputs and 16 isolated sinking outputs up to 24V
and 100mA per output. With its Option 1 mezzanine
board, an additional 32 inputs and 16 outputs are
provided, for a total of 96 I/O points in a single slot.
