Digital Output Timing Events
Timing Events specify how the hardware paces or clocks writing Digital Output
samples. DriverLINX uses the Timing Event to program when the DAS-1700 Series
writes the next digital output sample from the port.
The DAS-1700 Series supports the following Timing Events:
•
None—Output requires no pacing as DriverLINX is writing only a
single value.
•
Rate—The DAS-1700 Series supports fixed rate writing using internal
and external clocks.
None or Null Timing Event
The Null Event specifies that the task does not need a clock to determine when to
write the next sample.
