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
- Opto-coupler isolated input (compatible with current sink output) and opto-coupler isolated open-
collector output (current sink type)
This product has the opto-coupler isolated input 32channels (compatible with current sink output)
whose response speed is 200µsec and opto-coupler isolated open-collector output 32channels (current
sink type). Common terminal provided per 16channels, capable of supporting a different external
power supply. Supporting driver voltages of 12 - 24 VDC for I/O.
- Opto-coupler bus isolation
As the PC is isolated from the input and output interfaces by opto-couplers, this product has excellent
noise performance.
- Power for opto-coupler operation (12VDC 240mA) supplied internally
As the power to run the opto-couplers is supplied internally, no external power supply is required. The
use of jumpers allows you to decide whether you want to use the internal or external power supply for
every 16 points.
- You can use all of the input signals as interrupt request signals.
You can use all of the input signals as interrupt request signals and also disable or enable the interrupt
in bit units and select the edge of the input signals, at which to generate an interrupt.
- Windows/Linux compatible driver libraries are attached.
Using the attached driver library API-PAC(W32) makes it possible to create applications of
Windows/Linux. In addition, a diagnostic program by which the operations of hardware can be
checked is provided.

1. Before Using the Product
2PIO-32/32B(PCI)V
- This product has a digital filter to prevent wrong recognition of input signals from carrying noise
or a chattering.
This product has a digital filter to prevent wrong recognition of input signals from carrying noise or a
chattering. All input terminals can be added a digital filter, and the setting can be performed by
software.
- The output circuit, has a built-in Zener diode and the overcurrent protection circuit of the surge
voltage protection.
Zener diodes are connected to the output circuits to protect against surge voltages. In addition, the
output circuit, it attaches the overcurrent protection circuit at the output 8-channel unit. The output
rating is max. 35VDC, 100mA per channel.
- LabVIEW is supported by a plug-in of dedicated library.
Using the dedicated library makes it possible to make a LabVIEW application.

2. Setup
This chapter explains how to set up the board.
What is Setup?
Setup means a series of steps to take before the product can be used.
Different steps are required for software and hardware.
The setup procedure varies with the OS and software used.
Using the Board under Windows
Using the Driver Library API-PAC(W32)
This section describes the setup procedure to be performed before you can start developing application
programs for the board using the bundled disk “Driver Library API-PAC(W32)”.
Taking the following steps sets up the software and hardware. You can use the diagnosis program
later to check whether the software and hardware function normally.
Step 1 Installing the Software
Step 2 Setting the Hardware
Step 3 Installing the Hardware
Step 4 Initializing the Software
Step 5 Operation Checks
If Setup fails to be performed normally, see the “Setup Troubleshooting” section at the end of this
chapter.
Using the Board under an OS Other than Windows
For using the board under an OS other than Windows, see the following parts of this user’s guide.
