Step 3 Installing the Hardware

For using an expansion board under Windows, you have to let the OS detect the I/O addresses and
interrupt level 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 Add 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 to install the board, first determine what PC resources
are free to use.

- The resources to be used does not depend on the location of the PCI 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 resources previously assigned to the two
boards is assigned to the remounted board. In this case, you must check the resource settings.

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 simple checker when an external device is actually connected.
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.
Set the board in the default factory.

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 7, Vista, Windows XP, Server 2003, 20 00]

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.

If your problem cannot be resolved

Contact your retailer.

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

Data I/O Function

This board supports the equivalence to the mode 0 of two i8255 chips, capable of input/output of up to
48 TTL-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.

Data I/O

I/O signals are TTL levels and positive logic.

Input
When input data is low level, [0] is input to the corresponding bit.

When input data is high level, [1] is input to the corresponding bit.

Output
When [0] is output to the corresponding bit, low level is output to the external part.

When [1] is output to the corresponding bit, high level is output to the external part.

4. Function

Digital Filter Function

Using this feature, The DIO-48D2-PCI can apply a digital filter to every input pin, thereby preventing
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 clock signal. When the

Input Signal

Filter Setting Time

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, therefore, the level change is ignored.

Set Digital Filter Time

Set the digital filter time to 0 - 20 (14h).
Setting the digital filter time to 0 disables digital filtering. It is set to 0 when the power is turned on.
Figure 4.2 shows the relationships between digital filter time settings and the actual digital filter times.

4. Function

Interrupt Control Function

The DIO-48D2-PCI 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 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 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 fa ll of th e inpu t s ign al from High to Low).
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 th e inpu t s i gn al from Low to High).

CAUTION

When the power is turned on, all of the input signal edge selection bit are set to 0.

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.

- The interrupt status bits are set regardless of the state of the interrupt mask bit.
