1. Before Using the Product
This chapter provides information you should know before using the product.
About the Board
This board is a PCI bus-compliant interface board for input/output of digital signals.
It can be inputted by switch and relay.
PIO-32/32B(PCI)V can input and output up to 32 channels.
And this board is the equivalent of PIO-32/32B(PCI)H. For the detail, please refer to the chapter 6
Differences between PIO32/32B(PCI)H and PIO32/32B(PCI)V.
Using the bundled driver library package [API-PAC(W32)], you can create Windows application
software for this board in your favorite programming language supporting Win32 API functions, such as
Visual Basic or Visual C/C++.
Features
- A different external power supply can be used for each common pin as it is shared by 16 channels.
- The PCI bus (personal computer) and the I/O interface are isolated from each other by an opto-
coupler, offering good noise immunity.
- You can use all of the input signals as interrupt events.
You can also select the interrupt trigger edge of the input signal.
- The board has a digital filter feature to prevent noise or chatter from causing erroneous inputs.
- Up to 35VDC, 100mA per output signal, max..
- Zener diode connected to output transistors for protection from surge voltage. Overcurrent
protective device provided for every eight channels of output transistors.
- An on-board isolated supply(12VDC, 250mA) is equipped. You can select to use either this on
board supply or external power supply for driving photo-insulation circuits.

Support Software
You should use CONTEC support software according to your purpose and development environment.
Driver Library API-PAC(W32) (Bundled)
API-PAC(W32) is the library software that provides the commands for CONTEC hardware products in
the form of Windows standard Win32 API functions (DLL). It makes it easy to create high-speed
application software taking advantage of the CONTEC hardware using various programming languages
that support Win32 API functions, such as Visual Basic and Visual C/C++.
CONTEC provides download services at (http://www.contec.com/apipac/) to supply the updated drivers
and differential files.
For details, read Help on the bundled CD-ROM or visit the CONTEC’s Web site.
< Operating environment >
OS Windows XP, 2000, NT, Me, 98, etc..
Adaptation language Visual C/C++, Visual Basic, Delphi, Builder, etc..
Others Each piece of library software requires 50 megabytes of free hard disk space.
Linux version of digital I/O driver API-DIO(LNX) (Supplied: Stored on the API-PAC(W32)
CD-ROM)
This driver is used to control CONTEC digital I/O boards (cards) from within Linux.
You can control CONTEC digital I/O boards easily using the shared library used by gcc, Kylix, the
device driver (module) for each kernel version, and the board (card) configuration program (config).
CONTEC provides download services (at http://www.contec.co.jp/en/) to supply the updated drivers and
differential files.
For details, read Help on the bundled CD-ROM or visit the CONTEC’s Web site.
< Operating environment >
OS RedHatLinux, TurboLinux, etc..
(For details on supported distributions, refer to Help available after installation.)
Adaptation language gcc, Kylix
Others Each piece of library software requires 3 megabytes of free hard disk space.
Data acquisition VI library for LabVIEW VI-DAQ (Free download)
This is a VI library to use in National Instruments LabVIEW.
VI-DAQ is created with a functionform similar to that of LabVIEW's Data Acquisition VI, allowing you
to use various devices without complicated settings.
See http://www.contec.com/vidaq/ for details and download of VI-DAQ.
