The PCI-PIO is a PCI-compatible half-card which provides digital input/outputs and counter/timers. There are 48 TTL-compatible programmable digital input/outputs available from the board. If the controlling devices are used in handshake mode, the handshake lines are available as
interrupt sources. There are also three programmable counter/timers, the enable and clock inputs being available externally, if required ,and the outputs being accessible externally or as interrupt sources. A 4MHz crystal oscillator is available on board to allow the counter/timers to act as accurate timebases. All input/output lines are available at an industry standard 50 way D-type plug connector. One PCI interrupt line may be selectively driven by the seven interrupt sources on the board, the interrupting source being readily identified by the board.
