4.9 Trigger Detector
4.9.1 Using the Manual Trigger
The function "Manual Trigger" allows the user to generate a trigger event manually from
within MC_Rack. This can be used to create timestamps in a data file. Manual triggers can only
be generated during online data acquisition, and only in continuous mode. Manual triggers are
intended to mark external events like changing perfusion solution, turning on or off a pump,
changing temperature or similar events.
These triggers can NOT be used to mark specific signals, as the manual trigger will be generated
in real time when the button is pressed, but the signal displayed in MC_Rack is approximately
one second behind real time.
To use the manual trigger, insert a “Trigger Detector” in your rack and select "Manual Trigger"
from the bottom of the list in the “Channel” drop down menu. To generate a manual trigger,
press the “Trigger” button below the Channel drop down menu or the manual trigger icon in the
main menu toolbar. Each timestamp generated with the manual trigger will be counted up, and
stored in the “*.mcd” file. You just have to note which event is correlated with manual trigger 1,
2, 3 etc.. When replaying the marked data file in replayer mode, the manual trigger events will
always be shown on one channel of the display only: Using the MCS default two dimensional
channel map, the marker will appear on channel 47, in one dimensional channel layout on
channel 1.
