Measurement Computing's PC-CARD-DIO48 is a data acquisition and control board for PC compatible computers having PC-CARD/PCMCIA type slots. PC-CARD-DIO48 features two 82C55 digital I/O chips. The 82C55 chip uses TTL logic.
The digital I/O is organized into two 24-line groups (24 channels per 82C55). Each 24-line group is divided into three portsA, B, and C. Ports A and B are banks of 8 lines. Port C can be configured as two banks of 4 lines or one bank of 8 lines. Each bank is programmable as input or output.
On power up and reset, all I/O bits are set to input mode. All signals pass through a 50-pin high-density connector. The board is completely plug-and-play, with no switches or jumpers to set.
"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
