Introduction

ADLINK's PCIe-296 is a high-density parallel digital I/O board with 96 I/O channels. The header connectors are fully compatible with industry Opto-22 standard. Thus, PCIe-7296 can utilize the Opto-22 external devices. The PCIe-7296 device emulates mode 0 of the industry standard 8255 programmable peripheral interface (PPI) chips. The PCIe-7296 provides 4/2 PPI chips respectively. Each PPI offers three 8-bit ports: Port A, Port B and Port C. The Port C is divided into 2 nibble-wide (4-bit) ports. The PCIe-7296 device has programmable timer/counters. One 16-bit counter is available for event counting, while the other 32-bit timer is available for timed interrupt generation. The PCIe-7296 device provides multiple programmable interrupt sources from DIO channels, as well as the output of the timer.
