UMAC-CPCI Turbo CPU Board Hardware Reference Manual
INTRODUCTION
Delta Tau’s Compact UMAC systems provide a compact and clean integration of motion and I/O control
for sophisticated automation equipment. The Compact UMAC CPU was previously called the UMAC-
CPCI in previous revisions of this manual. The system consists of a modular set of 3U-size (100mm x
160mm) boards in the Compact PCI format, implementing Turbo PMAC software and hardware
functions, communicating with each other over a common backplane (the “Compact UBUS”). All field
wiring is available on rear connectors, suitable for a user-designed distribution system to the machine.
Compact UMAC (Universal Motion and Automation Controller) -CPCI systems provide integrated
connectivity as well as ease of assembly, diagnostics, and repair. Compact UMAC systems differ from
standard UMAC systems in that all field wiring comes to the back of the rack, behind the backplane,
instead of direct top and bottom access.
The Compact UMAC Turbo CPU board (Part number 3A0-603625-10x) implements a Turbo PMAC2
CPU in the 3U CPCI form factor. Its software operation is completely identical to other Turbo PMAC2
controllers.
The 603625 Compact UMAC Turbo CPU has two hardware versions that will be covered in this manual.
The difference between the two is the Flex CPU design upgrade on all new revisions released after the
spring of 2005. The Flex CPU allows the board to use an 80 MHz CPU, 160 MHz CPU, or 240 MHz
CPU. The old design allowed a maximum CPU speed of 100 MHz. The revision number is designated
by the last three numbers of the part number. For example, the part number for the current revision
release is the 603625-104 and we would call the board a revision 104 release. The legacy model CPU was
the 603625-102 and it would be designated as a revision 102.
Note that a Compact PCI interface does not come with a Compact UMAC system automatically, nor is
one necessary to communicate to the system, given the other possible communications ports: RS-232,
RS-422, USB, and Ethernet.
This picture shows the Compact UMAC Turbo CPU
board. The connectors on the right side plug into the
Compact UBUS backplane board, with the bottom
right connector being the bus connector, and the top
right connector containing the external field wiring
signals, which typically pass through the backplane
board. The connector at lower left is an RS-232 port
intended for setup and diagnostics; the stack
connectors top and bottom provide the link to a CPCI
bridge board.
