Plugging the Board

(1) Before plugging the board, shut down the system, unplug the power code of your PC. (2) Remove the cover from the PC so that the board can be mounted. (3) Plug the board into an expansion slot. (4) Attach the board bracket to the PC with a screw. (5) Put the cover back into place.
CAUTION
- Do not touch the board's metal plated terminals (edge connector) with your hands. Otherwise, the board may malfunction, overheat, or cause a failure. If the terminals are touched by someone's hands, clean the terminals with industrial alcohol.
- Do not install or remove the board to or from the slot while the computer's power or expansion unit is turned on. Otherwise, the board may malfunction, overheat, or cause a failure. Be sure that the personal computer power is turned off.
- Make sure that your PC or expansion unit can supply ample power to all the boards installed. Insufficiently energized boards could malfunction, overheat, or cause a failure.

Page 24
2. Setup

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 used by each PCI bus board do 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.

Setting with the Add New Hardware Wizard

(1) The “Add New Hardware Wizard” will be started.
Select “Specify the location of the driver”, then click on the [Next] button.
If you are using Windows NT 4.0, the “Add New Hardware Wizard” is not started. Go to Step 4 “Initializing the Software”.

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 test the input/output and check the execution environment. Check Mate (CM-32(PC)E) is convenient to check digital I/O boards. Set the board in the default factory.

Setup Troubleshooting

Symptoms and Actions

2. Setup
The board cannot be initialized [Windows NT 4.0 The driver may not yet be activated.
When using the board under an OS not compliant with Plug and Play, such as Windows NT 4.0, make sure that the [PnP OS] BIOS option has been set to [NO], [disable], or [Do not use]. If the option has been set to [Windows 95], for example, the board may not be detected normally. For details on BIOS settings, refer to the user’s guide for your PC.
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 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.

Connecting Input Signals

The Input circuits in the interface section of this board are illustrated in Figure 3.3. External digital signals given to signal inputs are TTL levels. The individual input signals are passed to the personal computer as active low signals. As each of the signal inputs is pulled up internally, the output of a relay contact or semiconductor switch can be connected directly between the signal input and the signal common pin.

Surge Voltage Countermeasures

When a load that generates surge voltages and inrush currents, such as an induction load (relay coil) or an incandescent light bulb, is connected to the digital output, appropriate protection must be provided in order to prevent damage to the output stage or a malfunction due to noise. The rapid shutoff of a coil, such as in a relay, generates a sudden high-voltage pulse. If this voltage exceeds the withstand voltage of the output transistor, it can cause the transistor to gradually deteriorate, or even completely damage the transistor. Therefore, when driving an induction load, such as a relay coil, you should always connect a surge-absorbing device. The following illustrates a surge voltage countermeasure that can be employed:

CAUTION
In order for a protection circuit to operate effectively, it must be connected within 50cm from a load and a contact point.

About the Protection Feature

The +5V output of the board is provided with a PolySwitch-based protection feature. If the +5V output is accidentally connected to GND, the protection feature works and it may disable the board temporarily. In that case, turn the PC off, wait for a few minutes, then turn the PC back on.

4. Function
This section describes the features of the board.

Data I/O Function

Data Input

When input data is “ON”, “1” is input to the relevant bit. When the input data is “OFF (high level)”, 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 (output is low level)”. When “0” is output to the relevant bit, in contrast, the corresponding transistor is set to “OFF (output is high level)”.
CAUTION
When the PC is turned on, all output are reset to 0 (OFF).

Monitoring Output Data

The PIO-16/16T(PCI) can read the state of the data currently being output without affecting the output data.
33
Page 41
4. Function

Digital Filter

Using this feature, the PIO-16/16T(PCI) 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, therefore, the level change is ignored.

Set Digital Filter Time

Set the digital filter time to 0 to 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.

Interrupt Control Function

When jumper JP1 has been set "to use interrupts," the board can use up to four input signals as interrupt request signals. I-00 to I-03 can be used 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 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, all of the interrupt edge select bits are set to 0 so that an interrupt occurs when the input value changes from 0 to 1 (at the fall of the input signal from 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.
- The interrupt status bits are set regardless of the state of the interrupt mask bit.
