Turbo PMAC2 VME Ultralite
Introduction 1
INTRODUCTION
The Turbo PMAC2 VME Ultralite is a member of the Turbo PMAC family of boards optimized for
interface to the system through the MACRO ring, and therefore does not contain on-board axis interface
circuitry (which is what makes it Ultralite). It can command up to 32 axes through the MACRO ring. It
can also support up to 32 channels of off-board axis interface circuitry through its expansion port,
connected to Acc-24P or Acc-24P2 boards.
The Turbo PMAC2 VME Ultralite is a VME-bus card. This card is capable of VME bus
communications, with or without the optional dual-ported RAM. Standalone operation is also possible
and communications can be done through RS-232 or RS-422.
Board Configuration

One manual per set of one to four PMACs in shipment
(Cables, mounting plates, mating connectors not included)
MACRO Ring Connector Options
If a MACRO interface is desired (which is the usual reason for use of the board), at least one of the
MACRO connector options must be selected.
Option A provides the MACRO-ring fiber optic SC-style interface connector. The key component on
the board is U4.
Option C provides the MACRO-ring RJ-45 electrical interface connectors. The key components on
the board are J14 and J17.
