Chapter 1: Introduction

Features

PowerDAQ DIO boards exist in a three different series:

PD2-DIO, which has 64 and 128 channel boards for the PCI bus and

utilizes 100-way boxed high-density ribbon cable connectors. 64-channel

boards come in a three different versions – static I/O, streaming I/O (-ST)

and counter/timer streaming (-CT). A 128-channel board is available in

static and streaming I/O versions only.

PDL-DIO, 64-channel half-size digital I/O boards which utilizes high-

density 96-way shielded metal pin-less connector. It’s ideal for the noisy

industrial environments and for the space-limited applications.

PDXI-DIO, 64-channel only boards for the cPCI/PXI bus. This is the most

robust and protected version, which shares all cabling and accessories

with PDL-DIO family, but also, implements PXI bus clocking and advanced

triggering support.

The major features of the PowerDAQ PD2-DIO board are:

• 24-bit 80/100 MHz Motorola 56301 DSP (Digital Signal

Processor). DSP runs at 66MHz in order to support 33MHz

32-bit PCI bus

• PCI/cPCI/PXI Bus Host PC Interface (PCI 2.1 Compliant)

• 64/128 lines (5 V/TTL) static I/Os in 16-bit ports;

• High output current drive (-32/64mA)

• Generate interrupts on any line;

• Four Separate High speed IRQ lines (100 ns);

• No legacy '8255' based devices;

• Ideal for solid state relays;

• Per bit user-defined power-up state in groups of 16-bit ports

(High, Low, Tri-stated);

• Two Enhanced Synchronous Serial Interfaces (ESSI);

• Up to three 24-bit counter timers with PWM/measurement

modes available;

• High Speed Digital Streaming to/from Disk (Optional), -ST

and –CT models only;

• Port scan list;

• Multiple boards synchronization via external connections or

PXI bus;
