User manual

trigger is available for Multi Frame DAQ modes only. With the trigger signal, you can use an external event to
start data acquisition or you can synchronize multiple CEBO-LC devices.
After startup TRG is configured as input signal, but inactive. To use TRG as a trigger, the corresponding
peripheral needs to be enabled first. This is done by software calls (API).
An example about using TRG terminal as Trigger Input/Output is provided in Programming Reference =>
C++ => Trigger.
Trigger Input
In Trigger Input mode, an external signal must be supplied to the TRG terminal. CEBO-LC supports three
different ways of trigger recognition.
Rising edge:
In rising edge mode, every transition from low to high on the TRG terminal is a trigger event.
Falling edge:
In falling edge mode, every transition from high to low on the TRG terminal is a trigger event.
Alternating:
In alternating mode, both edges are trigger events.
Trigger Output
You can use trigger output for hardware timed DAQ modes. The TRG signal becomes an actively driven
output. Depending on your settings (pulse mode, alternating mode) it toggles or pulses on every acquisition
of a frame.
