Set Sensor Parameter
optoNCDT 1320
Implemented trigger conditions:
Level triggering
with high level / low level.
Continuous measurement input resp. output, as long as the
selected level is applied. Then stops the data output.
The pulse duration must be at least one cycle time. The sub-
sequent break must also be at least one cycle time.

Edge triggering
with rising or falling edge.
Starts measured value acquisition resp. output as soon as
the chosen edge is applied to the trigger input. The sensor
outputs a fixed number of measurement values when trigger
conditions have been met. Value range from 1 ... 16383. After
termination of data output the analog output sticks to the last
value (sample & hold).
Pulse duration must be at least 50 µs.

Software triggering.
Starts the measurement value output, when a software command comes. The trigger
time is defined more inaccurately. After the trigger event the sensor outputs the preset number of measure-
ment values or starts a continuous measurement value output. If “0“ is selected for the number of measure-
ment values, the sensor stops the triggering and the continuous value output.
Measurement output can also be stopped by means of a command.
