Support Software

You should use CONTEC support software according to your purpose and development environment.

Windows version of counter input driver

API-CNT(WDM) / API-CNT(98/PC)

[Stored on the bundled CD-ROM driver library API-PAC(W32)]

The API-CNT(WDM) / API-CNT(98/PC) is the Windows version driver library software that provides products in the

form of Win32 API functions (DLL). Various sample programs such as Visual Basic and Visual C++, etc and

diagnostic program useful for checking operation is provided.

< Operating environment >

Windows 7, Server 2008, Vista, XP, Server 2003, 2000

Adaptation language

Visual Basic, Visual C++, Visual C#, Delphi, C++ Builder

You can download the updated version from the CONTEC’s Web site (http://www.contec.com/apipac/). For more

details on the supported OS, applicable language and new information, please visit the CONTEC’s Web site.

Linux version of general-purpose COUNT driver:

API-CNT(LNX)

[Stored on the bundled CD-ROM driver library API-PAC(W32)]

This driver is used to control CONTEC counter boards (PC Cards).

You can control CONTEC counter boards easily using the shared library used by gcc, Kylix, the device driver (module)

for each kernel version, and the board (PC Cards) configuration program (config).

CONTEC provides download services (at http://www.contec.com/apipac/) to supply the updated drivers and

differential files.

For details, read Help on the bundled CD-ROM or visit the CONTEC’s Web site.

< Operating environment >

RedHatLinux, TurboLinux, etc..

(For details on supported distributions, refer to Help available after installation.)

Adaptation language

gcc, Kylix

Others

Each piece of library software requires 3 megabytes of free hard disk space.

Data acquisition VI library for LabVIEW

VI-DAQ

(Free download)

This is a VI library to use in National Instruments LabVIEW.

VI-DAQ is created with a function form similar to that of LabVIEW's Data Acquisition VI, allowing you to use various

devices without complicated settings.

See http://www.contec.co.jp/vidaq/ for details and download of VI-DAQ.
