Datasheet: PCI-PIO 48 Channel Programmable Input/Output Card Blue Chip Technology www.bluechiptechnology.co.uk The PCI-PIO is a PCI-compatible half-card which provides digital input/outputs and counter/timers. There are 48 TTLcompatible 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. Options 1 metre cable with IDC and D type connector (P/N 1371 0071) 50 way screw terminal adapter (P/N 1981-0004) Windows(R) 98/2000, NT(R) and There are also three programmable counter/timers, the XP(R) drivers enable and clock inputs being available externally, if required. The outputs are 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.
