36 PMAC Basic Specifications
Options
Option 0
For PMAC VME only, reduces cost for standalone applications by removing the
special interface chip used to communicate with the VMEbus.
Option 1
Additional four channels each of: quadrature encoders, analog (DAC) outputs, analog
inputs (serial digital data from Acc-23 or Acc-28) for eight channels each on a
PMAC. On PMAC VME or PMAC STD, this option is a piggyback board. On
PMAC PC, this option is extra ICs on the baseboard. This option is not available for
PMAC Lite.
Option 2
8Kx16 Dual-ported RAM: for high-speed repetitious communication of data. On
PMAC VME, this option is extra ICs on the baseboard. On PMAC PC and Lite, this
option is a separate half-size board. This option is not available for PMAC STD.
Option 3
For PMAC VME, enhanced front plate that provides more connectors for auxiliary
I/O on the front plate.
Option 4A
Optional CPU section with 20 MHz CPU, 128K x 24 bit zero-wait-state Static RAM,
4 Mbit flash ROM for firmware and user program storage (no battery), on-board
buffers for expansion port. Provides approximately 25% computational speed
increase over base version.
Standard on all PMAC Packs purchased after July 1, 1995.
Option 5A
Optional CPU section with 40 MHz CPU, 128K x 24 bit zero-wait-state Static RAM,
4 Mbit flash ROM for firmware and user program storage (no battery), on-board
buffers for expansion port. Provides approximately 125% computational speed
increase over base version.
Option 5B
Optional CPU section with 60 MHz CPU, 128K x 24 bit zero-wait-state Static RAM,
4 Mbit flash ROM for firmware and user program storage (no battery), on-board
buffers for expansion port. Provides approximately 250% computational speed
increase over base version.
Option 5C
Optional CPU section with 80 MHz CPU, 128K x 24 bit zero-wait-state Static RAM,
4 Mbit flash ROM for firmware and user program storage (no battery), on-board
buffers for expansion port. Provides approximately 375% computational speed
increase over base version.
Option 6
Extended (Pole-Placement) Servo Algorithm: Firmware option for servo filter more
sophisticated than standard PID; to be used with difficult-to-control systems
(resonances, backlash, friction, disturbances, changing dynamics). Requires one-time
purchase of Acc-25A or Acc-25B.
Option 7
Mounting plate for PMAC PC (Opt-7) or PMAC VME (Opt-7V) to provide support in
standalone applications.
Option 8
Super-high accuracy clock crystal (<10 ppm) for long-term velocity accuracy.
Available for all CPU Options (standard, 4A, 5A, 5B, and 5C) with Opt-8A.
Option 9L
RS-422 serial interface for PMAC Lite. Replaces standard RS-232 interface.
Option 10
PROM Version Specification: Permits customer to specify version of firmware to be
installed onboard. If this option is not selected, newest firmware version is installed.
Option 14
Replacement of flag input opto-isolators with socketed shunts. This permits parallel
sub-count interpolation from Acc-8D Option 8 or equivalent, or 5V-level flag inputs
from Opto-22 or equivalent modules.
Option 15
Voltage to frequency converter chip for Wiper analog input on JPAN connector.
