3U Turbo CPU Board for UMAC Turbo and Turbo Stack
Introduction

INTRODUCTION
Delta Tau’s 3U-format Turbo PMAC systems combine the power of the Turbo PMAC family with an
integrated packaging strategy that gives the user revolutionary flexibility and ease of use. The heart of
these systems is the 3U Turbo PMAC CPU board, described in this manual. It can either be assembled
with piggyback accessory boards to form a “Turbo Stack,” or connected through a backplane to rack-
mounted accessories to form a UMAC (Universal Motion and Automation Controller) Turbo system.
UMAC systems provide integrated connectivity as well as ease of assembly, diagnostics, and repair.
UMAC CPU Boards
The UMAC is available with either of two CPU boards – Turbo PMAC2 or MACRO Station.
The Turbo PMAC2 CPU board creates a UMAC Turbo, a full PMAC controller completely capable of
standalone operation.
The MACRO Station CPU board creates a UMAC MACRO. It is a remote slave node on a MACRO
ring, requiring a PMAC2 controller to command it over the ring.
This manual describes the hardware for the UMAC Turbo CPU board; for the UMAC MACRO CPU
board, consult the hardware reference manual for that product.
Associated Manuals
This document is the Hardware Reference Manual for the 3U Turbo CPU board for a UMAC Turbo
system. It describes the hardware features and provides setup instructions.
Other manuals as well are needed to use the UMAC Turbo system. Each accessory to the 3U Turbo CPU
board has its own manual, describing its operation and any required software setup of the Turbo CPU.
The Software Reference Manual for the Turbo PMAC family and the User’s Guide for the PMAC or
Turbo PMAC families is also needed.
3U Board Configurations
The 3U boards can be configured in either of two fundamental assemblies – UMAC and Stack.
•
UMAC
– In the UMAC configuration (once called Pack) the 3U-format
boards are put together to communicate through a backplane bus called
the UBUS, with all boards installed in a Euro-card rack. In this
configuration, all 3U-format boards or modules can be installed or
withdrawn from the pack individually, providing ease of installation,
debugging, and repair.
The photo at right shows two boards connected through a backplane in the
UMAC configuration. They are not connected directly to each other.
•
Stack
– In the Stack configuration the 3U-format boards are put together
as a stack of piggyback boards, (right, below). This configuration is ideal
for compact, cost-sensitive embedded applications.

Configuration
Note:
The Stack boards and related breakout boards can be installed in a
Euro-card rack, creating a hybrid stack/pack configuration.
Because the Stack boards were developed first, this originally was
the only way of creating a pack configuration, and pulling boards
for service was an awkward chore. This configuration should now
be used for existing legacy systems only.
