TR-HT2xx LED Controller - User Manual
9.6
Simple FIFO mode
A sensor on IP1 detects the presence of a product . After a delay, OP1
triggers a camera. There may be several products between the sensor
and the camera.
The TR-HT stores each of the triggers and then outputs a pulse after the
correct delay. The configuration for this is shown below:

Resync mode
A sensor on IP1 detects the presence of a product . After a delay, OP1
triggers a camera. Image processing software processes the image (which
can take a variable length of time) and then sends a pass/fail message to
the TR-HT. The pass/fail is re-synchronised to the original product
presence and the reject gate is opened if necessary.
