The National Instruments DAQPad-6507 / DAQPad-6508 is a 96-bit parallel digital I/O device for computers with the universal serial bus (USB). It uses four 24-bit programmable peripheral interfaces (PPIs). Each PPI can be further divided into three 8-bit ports. The DAQPad-6507 is very flexible when interfacing to peripherals or other computers. It can operate in either a unidirectional or bidirectional mode and handshake with peripheral equipment. The DAQPad-6507 differs from the DAQPad-6508 in that it has built-in screw terminals instead of a 100 pin I/O connector.
