1. Before Using the Product
This chapter provides information you should know before using the product.
About the Board
This product is a PCI Express bus-compliant interface board that extends the digital signal I/O
functions of a PC.
This product is a 12 - 24VDC opto-coupler isolated type with opto-coupler isolated input 16ch and opto-
coupler isolated open-collector output 16ch. You can use all of the input signals as interrupt inputs.
Equipped with the power for opto-coupler operation (12VDC) supplied and the digital filter function
and output transistor protection circuit (surge voltage protection and overcurrent protection).
This product supports a Low Profile size slot and, if replaced with the supplied bracket, supports a
standard size slot, too.
Windows/Linux driver is bundled with this product.
Using the dedicated library VI-DAQ makes it possible to create each application for LabVIEW.
Features
Opto-coupler isolated input (supporting current sink output) and opto-coupler isolated open-collector
output (current sink type)
This product has the opto-coupler isolated input 16ch (supporting current sink output) whose response
speed is 200sec and opto-coupler isolated open-collector output 16ch (current sink type).
Common terminal provided per 16ch, capable of supporting a different external power supply.
Supporting driver voltages of 12 - 24 VDC for I/O
Opto-coupler bus isolation
As the PCI Express bus (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 events.
You can use all of the input signals as interrupt events and also disable or enable the interrupt in bit
units and select the interrupt edge.

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.
This product has a digital filter to prevent input signals from carrying noise or a chattering.
This product has a digital filter to prevent 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.
Output circuits include zener diodes for surge voltage protection and overcurrent protection circuit.
Zener diodes are connected to the output circuits to protect against surge voltages. Similarly,
overcurrent protection circuits are fitted to each group of 8ch outputs.
Functions are compatible with PCI Express compatible board DIO-1616B-PE and PCI compatible
board PIO-16/16B(PCI)H.
The functions same with PCI Express compatible board DIO-1616B-PE and PCI compatible board
PIO-16/16B(PCI)H are provided.
Functions and connectors are compatible with PCI compatible board PIO-16/16B(LPCI)H series.
The functions same with PCI compatible board PIO-16/16B(LPCI)H are provided.
In addition, as there is compatibility in terms of connector shape and pin assignments, it is easy to
migrate from the existing system.
LabVIEW is supported by a plug-in of dedicated library VI-DAQ.
Using the dedicated library VI-DAQ makes it possible to create each application for LabVIEW.

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 media “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 on your PC, install the Driver libraries from the bundled
API-PAC(W32).
Although some user interfaces are different depending on the OS used, the basic procedure is the
same.
About the driver to be used
Two Analog I/O drivers are available : API-DIO(WDM) and API-DIO(98/PC).
API-DIO(WDM) is a driver to perform analog I/O under Windows.
When this product is used, digital input/output high performance driver "API-DIO(WDM)" is used.
If you use this product with digital input and output high-performance driver 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 media attachments, select "all" from the "Installer" later in this chapter and
starts the execution environment and development environment packages installer
Please see the Help folder in the installed hardware installation instructions please see reference in
