Page 67 Using the 8255-Emulation Protocol Your NI 653X can perform handshaking I/O with devices that contain the 8255 chip, including the National Instruments NI PC-DIO-24/PnP, NI 650X family, and NI PC-DIO-96/PnP. Performing the 8255-emulation protocol with your NI 653X is similar to 8255 or 82C55 Programmable Peripheral Interface (PPI).
Page 68 Chapter 3 Timing Diagrams NI 653X terminology differs from 8255 terminology. • Input—The REQ line carries the 8255 STB (Strobe) input signal, and the NI 653X ACK line carries the 8255 IBF (Input Buffer Full) output signal. • Output—The REQ line carries the 8255 ACK input signal, and the NI 653X ACK line carries the 8255 OBF (Output Buffer Full) output signal.
