FLAG1 == Gate3[1].Chan[1].UserFlag == FrontUnivOut5 -> Pulser1 -> (active Low, 5000us delay 750us) Map: 40
Pulser 0: event 214 is 'ESC multipurpose event. In this case used as: start motion'
Pulser 1: maps event 40 = 'ESA_detector 100 Hz' >>> should be 77='ESC detector'
event 214 is set with the CTA. For tests one can set manually
caput SAR-EXPMX-EVR0:FrontUnivOut4-Src-Scale-SP 9 # Force High(0) -> arm event, before start motion
caput SAR-EXPMX-EVR0:FrontUnivOut4-Src-Scale-SP 8 # Force Low(1) -> trigger motion
caput SAR-EXPMX-EVR0:FrontUnivOut4-Src-Pulse-SP 0 # set back to Pulser 0 -> reset for CTA usage
