MACRO-CPU Hardware Reference
Assemblies of 3U-format boards can be made with either of two CPU processor boards – a 3U MACRO-CPU
board, or a 3U Turbo PMAC2 CPU board. Most other 3U-format boards, labeled “Accessory” boards, can be
used with either CPU board.
•
•
When the 3U MACRO-CPU board is used, the resulting assemblies are called “UMAC MACRO” or "3U
MACRO Stack."
When the 3U Turbo PMAC2 CPU board is used, the resulting assemblies are called “UMAC Turbo” or
"Turbo Stack."
Refer to the "UMAC & 3U Stack Products Selection Guide" for more detailed descriptions of how the rack and
stack products are integrated.

UMAC Turbo UMAC MACRO Turbo Stack MACRO Stack
The UMAC Turbo is composed of
a 3U-format Turbo PMAC2 CPU
board and a set of accessory boards
in 3U-format, all plugged in a
common UBUS backplane and
installed inside a 3U format rack. A
PC/104 computer and several
optional communication
accessories (including all of the
major FieldBuses, MACRO and
Ethernet) can be installed inside the
UMAC system providing
convenient flexibility and virtually
unlimited expandability. The UMAC MACRO is composed
of a MACRO Interface/CPU board
and a set of accessory boards in 3U-
format, all plugged in a common
UBUS backplane and installed
inside a 3U format rack. The UMAC
MACRO must receive commands
from an external MACRO
compatible device like a PMAC2
Ultralite or a UMAC Turbo system.
The UMAC MACRO does not
support a PC/104 or communication
accessories and it is preferred for
distributed control over a MACRO
ring connection. The Turbo stack is composed of a
3U-format Turbo PMAC2 CPU
board and a set of accessory boards
in 3U-format plugged to it in a stack
configuration. The Turbo stack
configuration is less expensive than
the UMAC Turbo system but it is
limited to eight axes of motion
control versus 32 axes on a UMAC
Turbo system. The Turbo Stack is
selected over a UMAC Turbo
system because is more compact,
allowing its installation inside
already existing cabinets with some
space limitations. The MACRO stack is composed of
a MACRO Interface/CPU board
and a set of accessory boards in
3U-format plugged to it in a stack
configuration. The UMAC
MACRO must receive commands
from an external MACRO
compatible device like a PMAC2
Ultralite or a UMAC Turbo
system. The MACRO Stack is
selected over a UMAC MACRO
syst em because it is more compact,
allowing its installation inside
already existing cabinets with some
space limitations.
