Register-level programming
You should use the Universal Library to control your board. Only experienced programmers should try register-
level programming. If you need to program at the register level in your application, refer to the Register Map
for the PCI-PDISO16 (available at www.mccdaq.com/registermaps/RegMapPCI-PDISO16.pdf).

Chapter 1
Introducing the PCI-PDISO16
This manual explains how to install and use the PCI-PDISO16 board. The PCI-PDISO16 is a 16-channel
isolated-input and relay output digital interface board for PCI-compatible computers. The board is designed for
applications where high voltages need to be sensed or controlled.
The PCI-PDISO16 board provides 16 digital inputs and 16 Form C relay outputs.
The 16 individual, optically isolated (500V) inputs can be read back as two 8-bit bytes. The inputs are not
polarity sensitive, and can be driven by either AC (50 to 1000 Hz) or DC at levels up to 28 Volts. Each input
channel has a software-enabled low-pass filter with a time constant of 5 ms (200 Hz).
The 16 outputs are dry contact, Form-C electromechanical relays. The relays are controlled by writing to two
eight-bit ports. The state of the relays can be determined by reading the same two ports.
The PCI-PDISO16 board is completely plug-and-play, with no switches or jumpers to set.
Software features
For information on the features of InstaCal and the other software included with your PCI-PDISO16, refer to
the Quick Start Guide that shipped with your device. The Quick Start Guide is also available in PDF at
www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf.
Check www.mccdaq.com/download.htm for the latest software version or versions of the software supported
under less commonly used operating systems.
