PMAC2A-PC104 Hardware Manual

Introduction 3

ACC-2P: Communications Board

Without any options, the PMAC2A-PC/104 communicates through the RS-232 serial interface using the

optional ACC-3L flat cable. Only one method of communication is allowed at a time.

ACC-2P Option 1A: USB Interface

Option 1A it provides a 12 Mbit/sec USB interface allowing USB communications with the PMAC2A-

PC/104 motion controller.

ACC-2P Option 1B: Ethernet Interface

Option 1B provides a 10 Mbit/sec Ethernet interface allowing Ethernet communications with the

PMAC2A-PC/104 motion controller.

ACC-2P Option 2: DPRAM Circuitry

Option 2 provides an 8K x 16 dual-ported RAM for USB, Ethernet or PC/104 ports on board of the ACC-

2P communications board. If using for USB or Ethernet communications, ACC-2P-Opt-1A or ACC-2P-

Opt-1B must be ordered. If used for PC/104-bus communications, PMAC2A-PC/104-Opt-2A must be

ordered. The key component installed with this option is U17.

ACC-2P Option 3: I/O Ports

Option 3 provides the following ports on the ACC-2P communications board for digital I/O connections.

• Multiplexer Port: this connector provides eight input lines and eight output lines at TTL levels. When

using the PMAC ACC-34x type boards these lines allow multiplexing large numbers of inputs and

outputs on the port. Up to 32 of the multiplexed I/O boards may be daisy-chained on the port, in any

combination.

• I/O Port: this port provides 16 general-purpose digital I/O lines at TTL levels and these can be

configured as all inputs, all outputs or eight inputs and eight outputs.

• Handwheel port: this port provides 2 extra channels, each jumper selectable between encoder input or

pulse output.

ACC-8TS Connections Board

ACC-8TS is a stack interface board to for the connection of either one or two ACC-28B A/D converter

boards. When a digital amplifier with current feedback is used the analog inputs provided by the ACC-

28B cannot be used.

ACC-8ES Four-Channel Dual-DAC Analog Stack Board

ACC-8ES provides four channels of 18-bit dual-DAC with four DB-9 connectors. This accessory stack

to the PMAC2A-PC/104 board and it is mostly used with amplifiers that require two ±10 V command

signals for sinusoidal commutation.

ACC-8FS Four-Channel Direct PWM Stack Breakout Board

ACC-8FS it is a 4-channel direct PWM stack breakout board for PMAC2A-PC/104. This is used for

controlling digital amplifiers that require direct PWM control signals. When a digital amplifier with

current feedback is used the analog inputs provided by the Opt-12 of the PMAC2A-PC/104, the Opt-2 of

the ACC-1P or the ACC-28B could not be used.
