The PCIDIO 3240 is our fastest I/O card, capable of data transport rates of up to 80MB per second. Such high speed comes from bus-mastering DMA and scatter/gather via a 32-bit PCI architecture, making this board highly suitable as an interface between high-speed peripherals and your computer.
This board is configured as two ports, Port A and Port B. Each port controls 16 DIO lines. These lines can be configured as input or output, 8-bit or 16-bit. Four different DIO modes are supported:
1. Internal clock: DIO operations are paced by an internal clock and transferred by bus-mastering DMA.
2. External clock: DIO operations are paced by an external strobe signal (DIREQ) and transferred by bus-masteirng DMA.
3. Handshaking: Through REQ and ACK signals the DIO data can have simple handshaking data transfer.
4. Pattern generation: You can output a digital pattern repeatedly at a predetermined rate. The transfer rate is controlled by an internal timer.
