//Simulated triggers uses Q variables
#define  SIMFLAG0 (pshm->Coord[1].Q[10])
#define  SIMFLAG1 (pshm->Coord[1].Q[11])
//real triggers, uses inputsfrom the EVR-card
//  s.a. Power PMAC Software Reference Manual.pdf Gate3[i].Chan[j].Status -> page 919 UserFlag
#define  FLAG0 (gate3_1->Chan[0].Status&0x800)
#define  FLAG1 (gate3_1->Chan[1].Status&0x800)

work of triggerSync program:
 - wait for [SIM]FLAG0 (arm trigger)
 - once armed, each [SIM]FLAG1 trigger is a frame trigger.

the EVR flags are set in;
caqtdm -attach -macro SYS=SAR-EXPMX,DEVICE=EVR0,FF=PCIe G_EVR_main.ui

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

Here values as they were set (??.10.24):

testing simulated start triggers
