How To: Set the Camera Output to Trigger a Different Device on Every Other Frame (Flip Flop)#
This solution is compatible with ace2, boost, dart IMX/M, and racer 2 cameras.
The goal is to alternate the camera's output line with each frame, allowing different lights or devices to be triggered in sequence. This setup behaves similarly to a flip-flop circuit.
This solution is applicable for customers who request a "Multiframe Trigger" feature, where two separate light sources would be triggered alternately with each frame. This is not a standard feature supported by Basler cameras.
However, it can be implemented using the camera’s Counter functionality. To achieve this behavior, apply the following configuration to the camera:
Counter 1:
Counter 2:
Line 2:
Line 3:
Start image acquisition to begin the Counter loop.
Note
On racer 2 cameras, the configuration described above will switch the trigger with each line of the image. To switch between full frames instead, set Counter Event Source = Frame Active for Counter 1 and Counter 2.
