1. Before Using the Product
This chapter provides information you should know before using the product.
About the Board
This product is a PCI-compliant interface board used to provide a digital signal I/O function on a PC.
This product can input and output digital signals at 12 - 24VDC.
PIO-16/16L(PCI)H features 16 opto-coupler isolated inputs and 16 opto-coupler isolated open-
collector outputs. You can use 16 input signals as interrupt inputs. In addition, the digital filter
function to prevent wrong recognition of input signals is provided and output transistor protection
circuit (surge voltage protection and overcurrent protection).
PI-32L(PCI)H features 32 opto-coupler isolated inputs. You can use 32 input signals as interrupt
inputs. In addition, the digital filter function to prevent wrong recognition of input signals is provided.
PO-32L(PCI)H features 32 opto-coupler isolated open-collector outputs. In addition, output transistor
protection circuit (surge voltage protection and overcurrent protection).
Windows/Linux driver is bundled with this product.
Possible to be used as a data recording device for LabVIEW, with dedicated libraries.
Features
- Opto-coupler isolated input (compatible with current sink output) and opto-coupler isolated
open-collector output (current sink type)
PIO-16/16L(PCI)H has the 16ch of opto-coupler isolated input (compatible with current sink output)
and 16ch of opto-coupler isolated open-collector output (current sink type) whose response speed is
200µsec. Common terminal provided per 16channels, capable of supporting a different external power
supply. Supporting driver voltages of 12 - 24 VDC for I/O.
PI-32L(PCI)H has the 32ch of opto-coupler isolated input (compatible with current sink output) whose
response speed is 200µsec. Common terminal provided per 16channels, capable of supporting a
different external power supply. Supporting driver voltages of 12 - 24 VDC for I/O.
PO-32L(PCI)H has the 32ch of opto-coupler isolated open-collector output (current sink type) whose
response speed is 200µsec. 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.
- You can use all of the input signals as interrupt request signals.
(For PIO-16/16L(PCI)H, PI-32L(PCI)H only)
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.

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.

Step 1 Installing the Software
This section describes how to install the Driver libraries.
Before installing the hardware in a PC, install "Driver Library API-PAC(W32)" from the
bundled media or download and install the latest edition of this software from the CONTEC web
site.
Although some user interfaces are different depending on the OS used, the basic procedure is the
same.
About the driver to be used
Two Digital I/O drivers are available : API-DIO(WDM) and API-DIO(98/PC).
When using this product, use the advanced digital I/O driver "API-DIO(WDM)". The following
information is focused on setting up API-DIO(WDM).
If API-DIO(98/PC) using existing systems continue to use API-DIO(98/PC).
Please note that the API-DIO(98/PC) does not support Windows 8 or later, and the 64-bit OS.
Use the API-DIO(98/PC)
If you are installing from disk attachments, select "all" from the "Installer" later in this chapter and
starts the execution environment and development environment packages installer
