1. Before Using the Product

1. Before Using the Product About the Board
This product is a PCI bus-compliant interface board that expands the input function of a PC for analog signals.
Maximum conversion speed is 10MSPS (100nsec), with simultaneous sampling of four channels at a same time. The large (32M data) buffer memory and bus master transfer function allow continuous data acquisition to be performed at high speed for a long period.
Sampling can be started and stopped by software, conversion data comparison (level comparison, in-range comparison, out-of-range co mparison), ex ternal trigger, or event controller output.
Uses a BNC connector that can connect directly to the signal source. Also features four digital input and output ports respectively (requires the optional DT-E3 cable). You can use the driver library (API-PAC(W32)) supplied with the board to write Windows application
programs in any programming language (such as Visual Basic, Visual C++, etc.) that supports the calling of Win32 API functions.

Features

- Maximum conversion speed is 10MSPS (100nsec), with simultaneous sampling of 4channels at a time
The maximum conversion speed is 10MSPS (100nsec) and 4channels can be sampled simultaneously. The range for each channel can be set independently by software to match the level of the input signal source. (Input range : ±10V, ±5V, ±2.5V, ±1.25V or 0 - +10V, 0 - +5V, 0 - +2.5V) Also features digital inputs and outputs (four LVTTL level input and output po rts respectiv ely). (requires the optional DT-E3 cable)
- Sampling can be controlled by software, conversion data comparison, external trigger, event controller output, and similar start and stop conditions
Sampling can be setup to be started and stopped by software, conversion data comparison, external trigger, or event controller output. Control of sampling start and stop is completely independent and a separate setting is provided for each. It is also possible to specify that sampling stop after a specified number of samples.
The conversion data comparison function can perform level, in-range, and out-of-range comparisons on the conversion data.
- Incorporates a synchronization control connector for synchronized operation
A synchronization control connector is provided for synchronized control of up to 16 boards. This means the number of channels can be increased simply by adding boards. It is also easy to synchronize operation with other CONTEC boards that have a synchronization control connector.

1. Before Using the Product
- Large (32M data) buffer memory and bus master transfer function allow continuous data acquisition at high speed for a long period.
The large (32M data) buffer memory and bus master transfer function allow continuous data acquisition to be performed at high speed for a long period. The bus master transfer function allows large volumes of data to be transferred between the board and PC without loading the CPU.
- BNC connector used for analog input pin
The BNC connector used for the analog input has a characteristic impedance of 50Ω and is of a type commonly used for high speed analog signal. This makes it easy to connect to other devices with a BNC connector.
- Termination resistor selection function
A 50Ω termination resistor can be set to minimize the distortion caused by the reflection of high-speed input signals. The input range cannot be set to ±10V or 0 to +10V when the termination resistor is used.
- Digital filter function included to prevent misdetection due to chattering on external input signals
A digital filter is included to prevent misdetection due to chattering on the digital input signals.
- Software-based calibration function
Calibration of analog input can be all performed by software. Apart from the adjustment information prepared before shipment, additional adjustment information can be stored according to the use environment.
- Windows compatible driver libraries are attached.
Using the attached driver library API-PAC(W32) makes it possible to create applications of Window. In addition, a diagnostic program by which the operations of hardware can be checked is provided.

Step 1 Installing the Software

This section describes how to install the API function 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

There are the two drivers "API-AIO(WDM)" and "API-AIO(98/PC)" among the analog input/output drivers.
API-AIO(WDM) is a new driver to perform analog input and output under Windows. It was developed aiming at "more easily use and more convenient" "more high performance"
corresponding to the product version of API-AIO(98/PC) so far. Please use the API-AIO(WDM) with this board. API-AIO(98/PC) is not supported.

Switch Setting for Termination Resistor

The termination resistor setting switch is used to insert the termination resistor. Set up the termination resistor if suitable for the device to which you are connecting. This product has internal 50Ω (±1%) termination resistors. SW4 sets the resistor for channel 0, SW3 for channel 1, SW2 for channel 2, and SW1 for channel 3.
CAUTION
- Do not change the switch setting while the signal source is connected. Changing the setting may damage this product or connected signal source.
- Th e in pu t cu rrent increases when the 50Ω termination resistor is inserted. Check the output current of the input signal source if connecting the termination resistor. Inappropriate use of the termination resistor may damage the input signal source.

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 scre w . (5) Put the cover back into place.
Applicable PCI bus slots PCI bus slots used in PCs have keys to prevent 5V and 3.3V PCI bus boards from being accidentally
plugged into wrong bus slots. This board can be plugged into both of the 5V and 3.3V PCI bus slots.

- 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 is turned on. Otherwise, the board may malfunction, overheat, or cause a failure. Doing so could cause trouble. Be sure that the personal computer or the I/O expansion unit 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.
- Power supply from the PCI bus slot at +5V is required.

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 IRQ to be used by the board. The process is referred to as installing the hardware.

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 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.

When Using the API-AIO(WDM)

(1) When the " Found New Hardware Wizard" opens, select "Install the software automatically
[Recommended]" and then click the "Next" button.
* The wizard may not appear for some OS versions and instead the installation will start
automatically. In this case, proceed to the software initial setup step.
