MACRO CPU Board
Introduction 1
INTRODUCTION
The 3U MACRO-CPU board is the processor and MACRO interface board that is used in a 3U MACRO
Station (in either UMAC MACRO or MACRO Stack configuration).
Note
Three documents describe the operation of Delta Tau Data Systems Inc. 3U
MACRO Station products:
• UMAC System Manual (General Product Overview)
• 3U MACRO Station User’s Manual
• 3U MACRO Station Software Reference
This manual describes the interfaces and physical hardware that is used on the 3U
MACRO CPU.
The UMAC MACRO and the MACRO Stack provide a remote interface for encoders, flags, direct-PWM
digital drives, analog drives, stepper drives, analog I/O, and digital I/O for Delta Tau Data's PMAC products
that have a MACRO interface.
The UMAC MACRO and MACRO Stack configurations communicate with PMAC2 Ultralites or Turbo
PMAC2 Ultralites solely through the MACRO ring, interfacing to standard drives, encoders, flags, and I/O
through on-board connectors. This MACRO Station integrated packaging and connectivity strategy provides
revolutionary flexibility and ease of use.
A 3U MACRO Station consists of a set of “3U” format Euro-cards (100 x 160 mm) that can be assembled in a
variety of configurations. When used in the rack configuration, connected through a backplane bus, the
backplane is UBUS format, designed by Delta Tau Data Systems Inc. for motion control and I/O interfaces.
When using the fiber optic MACRO interface, the 3U MACRO Station can be up to 3 kilometers (2 miles)
away from the PMAC2 controller or any other station on the ring. When using the RJ-45 copper electrical
interface, it can be up to 100 meters (~330 feet) away.
The 3U MACRO Station allows PMAC2 MACRO controllers to control servo axes and I/O just as if they were
directly connected to the PMAC2, even though they may be a great distance away. The only interface needed
from the PMAC2 is the electrically isolated MACRO ring.
Typically, a PMAC2 “Ultralite” board, one without any of its own servo interface circuitry, is used with the
MACRO Station to provide the most cost-effective solution.
