Step 3 Installing the Hardware
For using an extension board un der Window s, you have to let the OS detect t he I/O addresse s and IRQ to
be used by the board. The process is referred to as installing the hardware.
In the case of using two or more boards, make sure you install one by one with the Found New Hardware
Wizard.
Turning on the PC
Turn on the power to your PC.
CAUTION
- The board cannot be properly installed unless the resources (I/O addresses and interrupt level) for
the board can be allocated. Before attempting t o install the boar d, first det ermine what PC resources
are free to use.
- The resources used by each board do not depend on the location of the PCI Expr ess bus s lot or th e
board itself. If you remove two or more boards that have already been installed and then remount
one of them on the computer, it is unknown that which one of the sets of resources previou sly
assigned to the two boards is assigned to the remounted board. In this case, you must check the
resource settings.
Setting with the Found New Hardware Wizard
(1) First, “PCI Standard PCI to PCI Bridge” will be checked and end automatically.
(2) The “Found New Hardware Wizard” will be started.

Using the “Diagnosis Report” feature reports the driver settings, the presence or absence of the board,
I/O status, and interrupt status.
Check Method
Connect the board to a remote device to test the input/output and check the execution environment.
For this board, an external power supply is not needed.
The Check Mate (CM-32(PC)E) comes in handy when you check digital I/O boards.
Check the board with the factor defaults untouched.

Setup Troubleshooting
No output can be obtained.
Use API-TOOL Configuration to check whether the board name setting is wrong.
The board works with the Diagnosis Program but not with an application.
The Diagnosis Program is coded with API-TOOL functions. As long as the board operates with the
Diagnosis Program, it is to operate with other applications as well. In such cases, review your program
while paying attention to the following points:
- Check the arguments to functions and their return values.
- When the board is an isolat ed type, it has a tim e lag for its response between the output by a functio n
and the actual output. Consider the execution intervals between functions.
The OS won’t normally get started or detect the board. [Windows XP
Turn off the power to your PC, then unplug the board. Restart the OS and delete the board settings of
API-TOOL Configuration. Turn off the PC again, plug the board, and restart the OS. Let the OS detect
the board and use API-TOOL Configuration to register board settings.

4. Function
This section describes the features of the board.
Each function described here can be easily set and executed by using the bundled API function library.
For details, refer to API-DIO HELP available after installation.
Data I/O Function
Data Input
When input data is “ON”, “1” is input to the relevant bit.
When the input data is “OFF”, in contrast, “0” is input to the relevant bit
Data Output
When “1” is output to the relevant bit, the corresponding transistor is set to “ON”.
When “0” is output to the relevant bit, in contrast, the corresponding transistor is set to “OFF”.
CAUTION
When the PC is turned on, all output ar e reset to 0 (OFF).

4. Function
Digital Filter
Using this feature, this product can apply a digital filter to every input pin, thereby preventing the input
signal from being affected by noise or chattering.
Digital Filter Function Principle
The digital filter checks the input signal level during the sampling time of the clock signal. When the
signal level remains the same for the digital filter set time, the digital filter recognizes that signal as the
input signal and changes the signal level of the PC
If the signal level changes at a frequency shorter than the set time, there fore, the level cha nge is ignored.

4. Function
Interrupt Control Function
This product can use all of the input signals as interrupt request signals.
This product can generate an interrupt request signal to the PC when the input signal change from High
to Low or from Low to High.
When the digital filter (described above) is used, interrupt requests are generated by input signals that
have passed through the filter.
Disabling/enabling Interrupts
Interrupt mask bits can be used to disable or enable the individual bits for interruptions.
Once a certain bit has been interrupt-disabled, no interrupt occurs even when the corresponding input
signal changes its level.
To let interrupts occur, enable the corresponding interrupt mask bit for interruptions.
CAUTION
All of the interrupt mask bits are interrupt-disabled when the power is turned on.
Selecting the Interrupt Edge
Interrupt edge select bits can be used to set the input logic for interruption bit by bit.
If you set an interrupt edge select bit to 0, an interrupt occurs when the input value to the corresponding
bit changes from 0 to 1 (at the fall of the input signal from High to Low).
If you set an interrupt edge select bit to 1, an interrupt occurs when the input value to the corresponding
bit changes from 1 to 0 (at the rise of the input signal from Low to High).
CAUTION
When the power is turned on, a ll of th e inte rrup t edge select bits are set to 0 so that an interrupt
occurs when the input valu e cha ng es fr o m 0 to 1 (at the f all of the in put sign al f ro m High to Low ).
Clearing the Interrupt Status and Interrupt Signal
Interrupt status bits are used to identify the input signal bit being used for requesting an interrupt.
When an interrupt status is input, the interrupt request signal and the interrupt status are cleared
automatically.
CAUTION
- All of the interrupt status bits are set to 0 when the power is turned on.
- If an interrupt mask bit has been set to disable interrupts, the interrupt status bit is not set even whe n
the input signal changes its level.
