Introduction
ADLINK PCI-7296/7248/7224 are high-density parallel digital I/O boards with 96/48/24 I/O
channels. The header connectors are fully compatible with industry Opto-22 standard.
Therefore, PCI-7296/48/24 can utilize the Opto-22 external devices. The PCI-7296/7248/7224 devices emulate mode 0 of the industry standard 8255 programmable peripheral interface (PPI) chips. The PCI-7296/7248/7224 provides 4/2/1 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.
