  • Page 38: Wiring Digital Output (Open Collector) Signals

    Generally, open-collector outputs have the collector terminal of the output transition left open, or unconnected, to allow greater flexibility. In fact, the DT351 outputs provide open collectors and emitters, since each channel is completely isolated. This arrangement provides a further advantage in that it allows you to configure the circuitry using either positive or negative logic.

You enable the interrupts on a line-by-line basis during DT351 driver configuration;...

  • Page 57: 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.
