2-6-1 Trigger Mode
USB3-FRM13 can be used for an external trigger.
The figure below shows a circuit that trigger signal inputs through the connector J3 are
used to the general board input/output. This signals - are converted the CC (Camera
Control) signal of Camera Link inside FPGA logic - will send to the camera. Currently set to
CC1 ~ CC4 is shown below.
