Details Dialog Controls
1. Pulse: When this checkbox is enabled, the output will be pulsed. Disable this checkbox for a
steady-state output. The output must be pulsed when the Acquisition Delay is greater than 0.
2. Pulse Length (ms): Specifies the duration of an output pulse (10 to 1000 ms).
3. Acquisition Delay (N): Specifies the number of acquisition or tracking pulses (0 to 1000) to
delay the output after a signal pulse is received by an output Line. If Acquisition Delay = 0,
then the In-Sight device updates the output line immediately on evaluating the WriteDiscrete
function. If Acquisition Delay > 0, then the output Line is always pulsed.
4. Strobe Trigger: Rising Edge will trigger a strobe on the rising edge of the signal; Falling Edge
will trigger a strobe on the falling edge of the signal.
A.2 Configuring the Discrete Input
The Discrete Input Settings dialog (Figure A-2) configures the parallel input lines on the
active In-Sight sensor. Discrete input signals are read into the In-Sight spreadsheet using
the ReadDiscrete function. The number of accessible inputs varies per In-Sight model as
shown in Table A-4.
