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.

User's Guide Installing the PCI-PDISO16
Unpacking the board
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the PCI-PDISO16 from its packaging, ground yourself using a wrist strap or by
simply touching the computer chassis or other grounded object to eliminate any stored static charge.
If any components are missing or damaged, notify Measurement Computing Corporation immediately by
phone, fax, or e-mail:
!Phone: [phone] and follow the instructions for reaching Tech Support.
!Fax: [phone] to the attention of Tech Support
!Email: [email protected]
Installing the software
Refer to the Quick Start Guide for instructions on installing the software on the Measurement Computing Data
Acquisition Software CD. This booklet is available in PDF at www.mccdaq.com/PDFmanuals/DAQ-Software-
Quick-Start.pdf.
Installing the hardware
The PCI-PDISO16 board is completely plug-and-play. There are no switches or jumpers to set on the board.
Configuration is controlled by your system's BIOS. To install your board, follow the steps below.
Install the MCC DAQ software before you install your board
The driver needed to run your board is installed with the MCC DAQ software. Therefore, you need to install the
MCC DAQ software before you install your board. Refer to the Quick Start Guide for instructions on installing
the software.
1.
2.
3.
Turn your computer off, open it up, and insert your board into an available PCI slot.
Close your computer and turn it on.
If you are using an operating system with support for plug-and-play (such as Windows 2000 or
Windows XP), a dialog box pops up as the system loads indicating that new hardware has been detected. If
the information file for this board is not already loaded onto your PC, you will be prompted for the disk
containing this file. The MCC DAQ software contains this file. If required, insert the Measurement
Computing Data Acquisition Software CD and click OK.
To test your installation and configure your board, run the InstaCal utility installed in the previous section.
Refer to the Quick Start Guide that came with your board for information on how to initially set up and
load InstaCal.
Configuring the hardware
All hardware configuration options on the PCI-PDISO16 are software controlled. You can select some of the
configuration options using InstaCal. Once selected, any program that uses the Universal Library will initialize
the hardware according to these selections.

Field wiring and signal termination
You can use the following screw terminal boards to terminate field signals and route them into the PCI-
PDISO16 using the C50FF-x cable:
!CIO-MINI50 – 50-pin screw terminal board. Details on this product are available on our web site at
www.mccdaq.com/cbicatalog/cbiproduct.asp?dept_id=102&pf_id=258.
!CIO-TERM100 – 100-pin screw terminal board. Details on this product are available on our web site at
www.mccdaq.com/cbicatalog/cbiproduct.asp?dept_id=102&pf_id=258.
!SCB-50 – 50 conductor, shielded signal connection/screw terminal box provides two independent 50-pin
connections. Details on this product are available on our web site at
www.mccdaq.com/cbicatalog/cbiproduct.asp?dept_id=196&pf_id=1168.
You can use the following screw terminal boards to terminate field signals and route them into the PCI-
PDISO16 using the C50-37F-x adaptor cable:
!CIO-MINI37 – 37-pin screw terminal board. Details on this product are available on our web site at
www.mccdaq.com/cbicatalog/cbiproduct.asp?dept_id=102&pf_id=255.
!CIO-TERMINAL – 37-pin screw terminal board with on-board prototype area. Details on this product are
available on our web site at www.mccdaq.com/cbicatalog/cbiproduct.asp?dept_id=102&pf_id=282.
!SCB-37 – 37 conductor, shielded signal connection/screw terminal box provides two independent 37-pin
connections. Details on this product are available on our web site at
www.mccdaq.com/cbicatalog/cbiproduct.asp?dept_id=196&pf_id=1166.
Caution! Do not use the CIO-MINI50 screw terminal board if your field voltages are greater than 24 volts.
The CIO-MINI50 does not have shields to protect users from accidental contact with hazardous
high voltage signals. Construct a safe, fully insulated cable to carry your signals directly from your
equipment to the PCI-PDISO16 connector. If you use a screw terminal board, ensure that it is fully
enclosed in an insulated, protected box.
Additional signal conditioning is not required
The PCI-PDISO16 is designed with signal conditioning installed. Most accessory boards are intended to
provide signal conditioning or easy-to-access signal termination. In general, the PCI-PDISO16 does not require
additional signal conditioning.

Programming and Developing Applications
Programming languages
Measurement Computing’s Universal Library®provides access to board functions from a variety of Windows
programming languages. If you are planning to write programs, or would like to run the example programs for
Visual Basicor any other language, please refer to the Universal Library User's Guide (available on our web
site at www.mccdaq.com/PDFmanuals/sm-ul-user-guide.pdf).
Packaged applications programs
Many packaged application programs, such as SoftWIRE, Labtech Notebook™, and HP-VEE™, now have
drivers for your board. If the package you own does not have drivers for the board, please fax or e-mail the
package name and the revision number from the install disks. We will research the package for you and advise
how to obtain drivers.
Some application drivers are included with the Universal Library package, but not with the application package.
If you have purchased an application package directly from the software vendor, you may need to purchase our
Universal Library and drivers. Please contact us by phone, fax or e-mail:
!Phone: [phone] and follow the instructions for reaching Tech Support.
!Fax: [phone] to the attention of Tech Support
!Email: [email protected]
Register-level programming
You should use the Universal Library or one of the packaged application programs mentioned above 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).
