  • Page 19: Digital I/O Lines

    Principles of Operation Digital I/O Lines DT351 boards support eight dedicated digital input lines through the digital input (DIN) subsystem and eight dedicated digital output lines through the digital output (DOUT) subsystem. Channel-to-channel isolation of 250 VDC is provided by physical separation of the inputs and outputs and separate ground runs.

  • Page 20: Interrupts

    Chapter 2 Interrupts The DT351 board can generate a PCI-bus interrupt when any of the digital input lines changes state. This feature is useful when you want to monitor critical signals or when you want to signal the host computer to transfer data to or from the board. You enable the interrupts on a bit-by-bit basis during DT351 driver configuration.

  • Page 21: Operation Modes

    Principles of Operation Operation Modes DT351 boards support the following digital I/O operation modes: • Single-value operations are the simplest to use but do not allow you to check the interrupt status. Use software to specify the DIN or DOUT subsystem, a resolution of 8, and a gain of 1 (the gain is ignored).
