The last step of the begin sequence allows enough time for the CCUSB crate controller to switch from its interactive mode to data acquisition mode. The end sequence script executed at the end of a run sets the "Go" state of the module back to false. | The last step of the begin sequence allows enough time for the CCUSB crate controller to switch from its interactive mode to data acquisition mode.

===== Scalers and dead time ===== | ====== Scalers and dead time ====== |
The "D" connector of the trigger module is directly connected to 16 inputs of a scaler module (see mapping in the inputs and outputs section below). Scalers are connected to each of the trigger source inputs, as well as trigger box inputs. These scalers can be used to recover the number of trigger signals occurring on each of the source and trigger box inputs, in addition to the information coded for each event in the trigger register. | The "D" connector of the trigger module is directly connected to 16 inputs of a scaler module (see mapping in the inputs and outputs section below).
