Chapter 1
Introducing the PCI-PDISO8
Overview: PCI-PDISO8 features
The PCI-PDISO8 is an eight channel-isolated high voltage digital input and eight relay output interface board.
You can use the PCI-PDISO8 for control and sensing applications where high voltages need to be sensed or
controlled.
Caution! High voltages are present on the PCI-PDISO8 board when you connect high voltage inputs or
outputs to the PCI-PDISO8 connector. Use extreme caution! Never handle the PCI-PDISO8 when
signals are connected to the board through the connector.
Never remove the protective plates from the PCI-PDISO8.
The eight inputs are individual, optically-isolated (500 V) inputs that can be read back as a single byte. The
inputs are not polarity sensitive and may be driven by either AC (50 - 1000 Hz) or DC. Each input channel has a
programmable low-pass filter with a time constant of 5 ms (200 Hz).
The eight outputs are electromechanical relays. Five relays provide Form C connections, and three relays
provide normally-open Form A connections. The relays are controlled by writing to an eight-bit port. The relay
control register can be read back from the same port.
Signal conditioning installed
The PCI-PDISO8 is a combination digital I/O board with signal conditioning installed. Most accessory boards
provide signal conditioning or easy-to-access signal termination. The PCI-PDISO8 does not require additional
signal conditioning.
PCI-PDISO8 functions are illustrated in the block diagram shown here.

Chapter 2
Installing the PCI-PDISO8
What comes with your PCI-PDISO8 shipment?
The following items are shipped with the PCI-PDISO8.
Hardware
PCI-PDISO8
Software
MCC DAQ CD
Documentation
In addition to this hardware user's guide, you should also receive the Quick Start Guide. This booklet provides
an overview of the MCC DAQ software you received with the device, and includes information about installing
the software. Please read this booklet completely before installing any software or hardware.
Optional components
Cables
oC37FF-x and C37FFS-x
Signal termination boards
Measurement Computing provides signal termination boards for use with the PCI-PDISO8. Refer to Signal
termination on page 9 for more information.
Unpacking
As with any electronic device, you should take care while handling to avoid damage from static
electricity. Before removing the PCI-PDISO8 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: [e-mail]
For international customers, contact your local distributor. Refer to the International Distributors section on our
web site at www.mccdaq.com/International.
Installing the software
Refer to the Quick Start Guide for instructions on installing the software on the MCC DAQ CD. This booklet is
available in PDF at www.mccdaq.com/PDFmanuals/DAQ-Software-Quick-Start.pdf.
Installing the hardware
The PCI-PDISO8 is completely plug-and-play. There are no switches or jumpers to set. Configuration is
controlled by the system BIOS.

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.
Complete the following steps to install the board:
1. Turn your computer off, open it up, and insert your board into an available PCI slot.
2. Close your computer and turn it on.
When you connect the device for the first time to a computer running Windows, a Found New Hardware
dialog opens when the operating system detects the device. 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.
3. 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.

Information on signal connections
General information regarding signal connection and configuration is available in the Guide to Signal
Connections. This document is available on our web site at www.mccdaq.com/signals/signals.pdf.
Signal termination
You can use the following screw terminal board with the C37FF-x cable:
CIO-MINI37 –37-pin screw terminal board.
SCB-37 –37-conductor, shielded signal connection/screw terminal box.
Details on these products are available on our web site at www.mccdaq.com/products/screw_terminal_bnc.aspx.
Caution! Do not use exposed-screw terminal boards if your field voltage is more than 24 volts. Using a
screw terminal board with high voltage inputs or outputs exposes you and others to those high
voltage signals. Construct a safe cable to carry your signals directly from your equipment to the
PCI-PDISO8 connector.
Additional information about digital interfacing
Detailed information about digital interfacing is contained in the Guide to Signal Connections. This document is
available on our web site at www.mccdaq.com/signals/signals.pdf.
