- The board cannot be properly installed unless the resources (I/O addresses and interrupt level) for
the board can be allocated. Before attempting to install the board, first determ ine what PC resource s
are free to use.

- The resources used by each board do not depend on the location of the PCI Express bus slot or the
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 res ources previous ly
assigned to the two bo ards is assi gned to th e re moun ted bo ard . In th is c ase , you mus t ch e ck th e

Step 5 Checking Operations with the Diagnosis Program

Use the diagnosis program to check that the board and driver software work normally, thereby you can
confirm that they have been set up correctly.

What is the Diagnosis Program?

The diagnosis program diagnoses the states of the board and driver software.
It can also be used as a si mple ch ec k er when an ex t ern al dev i ce i s actu all y co nn ect ed .
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 text the input/output and check the execution environment.
To connect the external device, see Chapter 3 “External Connection”.

Setup Troubleshooting

Symptoms and Actions

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 isolated type, it has a time lag for its response between the output by a function
and the actual output. Consider the execution intervals between functions.

The OS won’t normally get started or detect the board.
[Windows Vista, Windows XP, Server 2003, 2000]

Turn off the power to your PC, then unplug the board. Restart th e OS and delete the board setting s of
API-TOOL Configuration. Turn off the PC ag ai n, pl ug the board, a nd res tart the OS. Let the OS detect
the board and use API-TOOL Configuration to register board settings.

inductive load such as a relay coil or incandescent lamp, suitable protection measures are required to
prevent damage to the output stage or malfunction owing to noise. The instantaneous interruption of
current flowing through a coil, includi ng a relay ,re sults in the s udden generat ion of a hi gh-voltage p ulse.
If the voltage exceeds the withstand voltage of the transistor, the transistor performance may be
degraded or the transistor may be damaged. To prevent this, be sure to connect a surge absorption
element when driving an inductive load including a relay coil. Examples of measures against voltage
surge are shown in Figure 3.7. below.

4. Function

This section describes the features of the board.
Each function described here can be easily set and executed by usi ng the bundled API dr iver library. For

details, refer to API-DIO HELP available after installation.

Data I/O Function

This board supports the equivalence to mode 0 of four i8255 chips, capable of input/output of up to 96
LVTTL-level active high signals.

I/O setup of the port

The I/O function of the port must be set properly before the board can input/output data correctly.
Writing a control word sets each port for either input or output.
The input/output setting can be achieved in eight signals unit for ports A and B and in four signals unit
(upper 4 bits and lower 4 bits) for port C.

CAUTION

Each port is assigned as an input port when the power is turned on.

Digital Filter Function

Using this feature, the < DIO-96D-L PE > can apply a di gital filter to ever y input pin, t hereby pr eventing
wrong recognition of input signals from carrying noise or a chattering.

Digital Filter Function Principle

The digital filter checks the input signal level during
the sampling time of the c lo ck si gnal . Wh en the

signal level remains the same for the digital filter set
time, the digital filter recognizes that signal as the

If the signal level changes at a frequency shorter than
the set time, therefore, the level change is ignored.

4. Function

Interrupt Control Function

The < DIO-96D-LPE > can use all of the input signals as interrupt request signals.
The board can generate an interrupt request signal to the PC when the input signal change fr om 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 correspondi ng inp ut
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 edge of input signals, at which to generate an interrupt

The input signal edge selection bit can be used to set the input logic for interruption bit by bit.
If you set an input signal edge selection 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 fro m High to Lo w).
If you set an input signal edge selection 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 sign al from Low to High).

CAUTION

When the power is turned on, al l of th e i nput signal edge selection bit are set to 0.

Clearing the Interrupt Status and Interr upt Sig nal

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 i nterrupts, the i nterrupt status bit i s not set even whe n
the input signal changes its level.
