PMAC2A PC104 Hardware Reference Manual

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 Option-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 two 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 is stacked 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 Option 12 of the PMAC2A PC/104 (the Option 2 of the Acc-1P or the Acc-28B) could not be used.
