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
- Optocoupler isolated inputs (compatible with current sink output), and Optocoupler isolated
open-collector outputs (current sink type)
DIO-6464L-PE has the 64 channels of Optocoupler isolated input (compatible with current sink output)
and 64 channels Optocoupler isolated open-collector output (current sink type) whose response speed is
200µsec. Common terminal provided per 16 channels, capable of supporting a different external power
supply. Supporting driver voltages of 12 - 24 VDC for I/O.
DI-128L-PE has the 128 channels of Optocoupler isolated input (compatible with current sink output)
whose response speed is 200µsec. Common terminal provided per 16 channels, capable of supporting a
different external power supply. Supporting driver voltages of 12 - 24 VDC for I/O.
DO-128L-PE has the 128 channels of Optocoupler 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.
- Optocoupler bus isolation
As the PC is isolated from the input and output interfaces by Optocoupler, this product has excellent
noise performance.
- You can use 16 input signals as interrupt request signals. (For DIO-6464L-PE, DI-128L-PE only)

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 applications 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 CD-ROM “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 Checking Operations with the Diagnosis Program
If Setup fails to be performed normally, see the “Setup Troubleshooting” section at the end of this
chapter.

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)
CD-ROM.
The following description assumes the operating system as Windows XP. 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).
API-DIO(WDM) is a new driver to perform digital I/O under Windows.
API-DIO(WDM) was developed to improve the conventional product version of API-DIO(98/PC) in the
ease of use and functionality.
It is advisable to use API-DIO(WDM) for you to use an digital I/O device. API-DIO(WDM) will
support new OS and devices in the future but will not support Windows NT 4.0, Windows 95, ISA bus.
Use API-DIO(98/PC) if your operating environment contains such an unsupported piece of software or
hardware.
Check the following selection guide to easily select the driver to be used.
