PIO-32DM(PCI)
1. Before Using the Product
This chapter provides information you should know before using the product.
About the Board
The PIO-32DM(PCI) is an interface board in compliance with the PCI bus specification and performs
high-speed digital input and output application using bus mastering. This should be installed in a PCI
bus slot.
The board can input and output a total of 32 TTL-level digital signals. Select input or output for each
16 signals.
Using the bundled driver library [API-PAC(W32)], you can create Windows application software for
this board in your favorite programming language supporting Win32 API functions, such as Visual
Basic or Visual C/C
++.
Feat ure s
Since the board supports bus master, it is suited for fast-processing and controlling applications to
control external devices with output of any digital pattern or to quickly sample digital input. The
board is also equipped with synchronization control connectors to solve timing lag problems during
channel expansion.
However, since the board is susceptible to electrical disturbances, it should be used for applications with
a short wiring distance and in quiet environment.
- With bus master, the board transfers data between the PC and board at a speed of 80MB/sec. (133
MB/sec. at maximum) without any burden on the CPU.
- The board stores digital signals at a sampling rate of 20 MHz and can detect patterns (pattern input).
- The board can be used as a 20 MHz digital pattern generator (pattern output).
- A 1K-Word on-board FIFO memory is installed each for input and output.
- The 32-bit I/O lines can configure as either input or output, and 16-bit or 32-bit. The board can be
set to 32-bit input lines, or 16-bit lines each for input and output, or 32-bit output lines.
- In addition to the digital I/O lines, control signals are available to start or stop pattern I/O. To
achieve high-speed access to peripherals, the board also supports the REQ and ACK handshaking
signals.
- The board is equipped with an SC connector to allow easy inter-board synchronization between the
same or different boards.
- The board can be used not only for pattern I/O using bus mastering but also as a general-purpose
digital I/O board. In general-purpose input mode, four input lines are available to interrupts
(rising edge).
- Interrupts are set by the software, not by the hardware.
- The board is installed with a timer available to applications to accurately monitor time even when
the board is used in Windows environment.

Step 1 Installing the Software
This section describes how to install the Driver 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 to be used
Two digital I/O drivers are available : API-DIO(WDM) and API-DIO(98/PC).
API-DIO(WDM) is a new driver to perform digital I/O under Windows.
API-DIO(WDM) was developed to improve the conventional product version of API-DIO(98/PC) in the
ease of use and functionality.
It is advisable to use API-DIO(WDM) for you to use an digital I/O device. API-DIO(WDM) will
support new OS and devices in the future but will not support Windows NT 4.0, Windows 95, ISA bus.
Use API-DIO(98/PC) if your operating environment contains such an unsupported piece of software or
hardware.
Check the following selection guide to easily select the driver to be used.
