5. Set the Signal option.
The signal type specifies whether the digital output is a continuous signal or a pulsed signal. If Signal is
set to Continuous , the signal state is maintained until the next transition occurs. If Signal is set to is
Pulsed , you must specify the pulse width and how it is scheduled.
6. Specify a pulse width using the slider.
The pulse width is the duration of the digital output pulse, in microseconds.
7. Check the Scheduled option if the output needs to be scheduled; otherwise, leave it unchecked for
immediate output.
A scheduled output becomes active after the delay from the start of Gocator exposure. A scheduled
output can be used to track the decisions for multiple objects as these objects travel from the sensor to
the eject gates.
The Delay setting specifies the distance from the sensor to the eject gates.
An immediate output becomes active as soon as measurement results are available. The output
activates after the sensor finishes processing the data. As a result, the time between the start of sensor
exposure and output activates can vary and is dependent on the processing latency. The latency is
reported in the dashboard and in the health messages.
8. If you checked Scheduled , specify a delay and a delay domain.
The Delay specifies the time or encoder distance between the start of sensor exposure and when the
output becomes active. The delay should be larger than the time needed to process the data inside the
sensor. It should be set to a value that is larger than the processing latency reported in the dashboard
or in the health messages.
The unit of the delay is configured with the Delay Domain setting.
9. If you want to invert the output signal, check Invert Output Signal .
To output a measurement valid signal:
1. Go to the Output page.
2. Click on Digital 1 or Digital 2 in the Output panel.
3. Set Trigger Event to Measurement .
4. In Configuration , set Assert On to Always .
5. Select the measurements.
The output activates when the selected decisions produce results. The output activates only once for
each frame even if multiple decision sources are selected.
6. Specify a pulse width using the slider.
The pulse width determines the duration of the digital output pulse, in microseconds.
To respond to software scheduled commands:
1. Go to the Output page.
2. Click Digital 1 or Digital 2 in the Output panel.
