Triggers
DT3130 Series boards provide the following trigger sources:
• A software trigger
−
The board can acquire a frame when a
software command is issued.
• An external trigger
−
By attaching a digital signal to an external
trigger input on the board, you can synchronize frame
acquisitions with external events.
You program the trigger source for the acquisition using software.
Table 3 shows the connectors on the EP312 cable provided for
connecting external trigger inputs to a DT3130 Series board.
