This PCI version of the DIO 48 card provides 48 TTL digital output lines. Two 8255 compatible programmable peripheral interface chips, with TTL buffered output, give a total of six 8 bit ports. These 48 i/o lines with 1 ground and one +5V/GND selectable output line are accessible from the 50 way D edge connector. Each port can be pulled high or low by optional on-board resistor networks. All 8255 modes are fully supported, the ports can be programmed in many i/o combinations, several with interrupt capability. Supplied with Quanta 2000 device drivers and Active X control. Active X controls allow easy data capture directly into any Active X enabled application. e.g. HPVEE, Labview, Microsoft Excel. Supplied complete with sample source code and online documentation.
