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.
The PCI-7296/7248/7224 devices have
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 PCI-7296/7248/7224 devices provide multiple
programmable interrupt sources from DIO
channels, as well as the output of the timer.
