About Software for Linux

The Linux version of digital I/O function driver, API-DIO(LNX), provides functions that execute the
following features:

Digital input/output of specified ports

Digital input/output of specified bits

Hardware digital filtering that prevents chattering

For details, refer to the help file. The help file provides various items of information such as “Function

Reference”, “Sample Programs”, and “FAQs”. Use them for program development and
troubleshooting.

Driver Software Install Procedure

The Linux version for digital I/O driver, API-DIO(LNX), is supplied as a compressed file
/linux/dio/cdioXXX.tgz on the bundled disk. (Note: XXX represents the driver version.)

Mount the bundled disk as shown below, copy the file to an arbitrary directory, and decompress the file
to install the driver.

For details on using the driver, refer to readme.txt and the help file in HTML format extracted by
installation.

To install the driver, log in as a superuser.

Decompression and setup procedure

# cd
