Introduction
This chapter describes the basic features of the PowerDAQ PD2/PDL/PDXI
DIO boards.
About the PowerDAQ DIO board
Thank you for purchasing a PowerDAQ DIO board. The PowerDAQ DIO
board was designed from the ground-up to provide you a best possible
features, reliability and performance available.
The associated PowerDAQ DIO software suite has been written specifically
for these products. Numerous third-party software products are supported
including real-time OS, like QNX and RT-Linux.
Overview
All PowerDAQ Digital IO boards where designed for better
manufacturability and corrected the flaws of 8255 based DIO boards. The
PD2/PDL/PDXI-DIO is feature rich; no longer do you have to design
external circuitry for start-up states, work against problems associated with
the 8255 and relays nor have a separate mechanism for generating
interrupts. Additionally, it features ESD protected I/Os and automatic user-
defined values load on power-up, which loads 10mS after the system reset.
The PD2/PDL/PDXI-DIO has it all and more and is the lowest cost of
ownership board on the market.
The PowerDAQ digital input/output boards are configured as 64 or
128 (PD2-only) lines. Board uses 16-bit line drivers, (not 8255 devices)
which allow you to configure the start up states in groups of 16-bit ports.
The on-board DSP/PCI interface allows you to use up to three 24-bit
counter timers, four additional 100nS high speed IRQ lines and two
16.5Mbit/s high speed ESSI ports.
