Measurement Computing's PCI-INT32 is possibly the most powerful digital I/O accessory available for the personal computer. The PCI-INT32 can accept up to 32 vector interrupts and output an interrupt to the PC. The board has a pair of Z8536 I/O chips interfaced to the PCI bus. Each Z8536 accepts up to 16 independent inputs that can be used to generate interrupts from bit patterns or individual bit states or transitions. The interrupt outputs from two X8536 chips can be ANDed using software.
Many other functions can be performed by the PCI-INT32 including digital pattern recognition, counting with six 16-bit counters, and up to 40 bits of digital I/O.
The 16-bit counters can be set up independently or chained together in groups of three.
The I/O pins of the Z8536 are TTL levels. All I/O lines are accessible through a 50-pin header connector. Connections to the board typically use the C50FF-# cable and the CIO-MINI50 terminal board.
"When we started designing these systems, we needed to locate a robust data acquisition unit that we could trust, have multiple inputs and a simple but effective software interface and a reasonable price." Michael Gray, Precia Molen
"We have used MCC devices for many years on any number of different projects, from pile testing to seismic tests, and we've always been more than satisified with their performance. This was the natural choice for us." Stephen Kemp, Manager, GBG Structural Services
