Operation
combiSENSOR 64x0
Level triggering (high level). Continuous measurement output
with adjusted data rate, as long as the selected level is active.
After that the controller stops the output of the measuring
values.

Edge triggering. Starts measuring value output, as soon as
the rising edge on the trigger input is active. If trigger condi-
tions are met, the controller outputs a measuring value. The set
data rate must be higher than the maximum trigger frequency.
If triggering is faster than the set data rate, individual measu-
ring values are transmitted twice, because internally no new
measuring values of the AD converter are active.
The duration of the pulse must be at least 5 µs.

Gate rising edge. Starts measuring value output with set data
rate, as soon as the rising edge on the trigger input is active.
Another rising edge stops the measuring value output respec-
tively switches it on again.

Software triggering ($GMD). A measuring value is output per channel, as soon as a command is sent. The
point of time is not defined as accurately.
No trigger is set ex factory. The controller starts the data transfer immediately after the switching on.
