Before Using the Product
This chapter provides information you should know before using the product.
About the Board
This product is a PCI-compliant interface board that inputs and counts pulse signals from an external
device.
This product has eight channels of 32-bit up/down counters, allowing external devices such as a rotary
encoder and a linear scale to be connected. Given below are examples of using the board for
“detecting a position of the table of a machine tool” and “detecting a change in weight”.
The pulse signal incoming interface is differential line receiver input or TTL level -compatible input
that can receive pulse signals at high speed.
When run with the dedicated support software, the application for this board can transfer data between
the board and the PC at high speed using PCI bus mastering.
<Example >
Features
- Capable of receiving two-phase and single-phase signals.
- Capable of receiving pulse signals of up to 10 MHz (The minimum discernible phase difference in
two-phase signal input mode is 25 nsec.)
- Capable of selecting the differential line receiver input or TTL level -compatible input mode for
each channel.
- Protective device attached to the input circuit, providing surge protection.
- Capable of discontinuity detection in differential line receiver input mode.
- One control signal input pin per channel.
- Capable of count values sampling at a maximum sampling rate of 20 MHz.
- Supporting PCI bus mastering, enabling high-speed data transfer between the board and the PC
without intervention from the CPU.
- Detecting a position of the table of a machine tool

Setup
This chapter explains how to set up the board.
What is Setup?
Setup means a series of steps to take before the product can be used.
Different steps are required for software and hardware.
The setup procedure varies with the OS and software used.
Using the Board under Windows
Using the Driver Library API-PAC(W32)
This section describes the setup procedure to be performed before you can start developing application
programs for the board using the bundled disk “Driver Library API-PAC(W32)”.
Taking the following steps sets up the software and hardware. You can use the diagnosis program later
to check whether the software and hardware function normally.
Step 1 Installing the Software
Step 2 Setting the Hardware
Step 3 Installing the Hardware
Step 4 Initializing the Software
Step 5 Operation Checks
If Setup fails to be performed normally, see the “Setup Troubleshooting” section at the end of this
chapter.
Using the Board under an OS Other than Windows
For using the board under an OS other than Windows, see the following parts of this user’s guide.

CNT32-8M(PCI)
Step 1 Installing the Software
This section describes how to install the Driver libraries.
Before installing the hardware in a PC, install "Driver Library API-PAC(W32)" from the
bundled media or download and install the latest edition of this software from the CONTEC web
site.
Although some user interfaces are different depending on the OS used, the basic procedure is the same.
About the driver to be used
Two counter drivers are available : API-CNT(WDM) and API-CNT(98/PC).
When using this product, use the advanced digital I/O driver "API-CNT(WDM)". The following
information is focused on setting up API-CNT(WDM).
- If you intend to use this product in the existing system where API-CNT(98/PC) is used, continue to use
API-CNT(98/PC).
Please note that the API-CNT(98/PC) does not support Windows 8 or later, and the 64-bit OS.
- Use the API-CNT(98/PC)
If you are installing from disk attachments, select "all" from the "Installer" later in this chapter and
starts the execution environment and development environment packages installer.
Please see the Help folder in the installed hardware installation instructions please see reference in help
disk attachments or downloaded from CONTEC’s Web site development environment.
Furthermore, that applies to the default step 4 software described below, see config.chm folder
