This manual provides installation, driver setup, and programming instructions for the KRXGK KPCI-842 optically isolated digital input card.
The KPCI-842 interface card is designed for PCI bus slots in original, compatible, and industrial control computers. It is widely used in industrial process control systems and laboratory applications for monitoring changes in switch states. The card connects to external devices via a 37-pin D-type connector on the card.
The document details the installation process, including static discharge precautions and pin definitions for the 32 digital input channels (DI). It also covers the installation of the driver software and provides specific library function examples for Visual C++ and Visual Basic to read and write data from the card. This manual is written in Chinese.
