RE: Manta G-235B Camera

Hi Steve,

 

• In the past (pre-vimba)  we had  cam1:TriggerDelay - although hardly ever touched it - is that PV still valid?  if so what are the units?

 

My Manta G-507C camera has these camera-specific PVs that come from the camera features XML file:

 

(base) [epics@corvette db]$ grep -i delay AVT_Manta_G507C.template

record(ai, "$(P)$(R)GC_TriggerDelayAbs_RBV") {

  field(INP,  "@asyn($(PORT),$(ADDR=0),$(TIMEOUT=1))GC_D_TriggerDelayAbs")

record(ao, "$(P)$(R)GC_TriggerDelayAbs") {

  field(OUT,  "@asyn($(PORT),$(ADDR=0),$(TIMEOUT=1))GC_D_TriggerDelayAbs")

record(ai, "$(P)$(R)GC_StrobeDelay_RBV") {

  field(INP,  "@asyn($(PORT),$(ADDR=0),$(TIMEOUT=1))GC_I_StrobeDelay")

record(ao, "$(P)$(R)GC_StrobeDelay") {

  field(OUT,  "@asyn($(PORT),$(ADDR=0),$(TIMEOUT=1))GC_I_StrobeDelay")

record(ai, "$(P)$(R)GC_FraStaTriDelay_RBV") {

  field(INP,  "@asyn($(PORT),$(ADDR=0),$(TIMEOUT=1))GC_I_FrameStartTriggerDelay")

record(ao, "$(P)$(R)GC_FraStaTriDelay") {

  field(OUT,  "@asyn($(PORT),$(ADDR=0),$(TIMEOUT=1))GC_I_FrameStartTriggerDelay")

 

It looks like the first one (TriggerDelayAbs) probably corresponds to the TriggerDelay you previously used with ADProsilica. 

 

The time units for all GenICam features are microseconds.

 

• Also tried cam1:ShutterOpenDelay and cam1:ShutterCloseDelay .....  never used these in the past, not sure how they are used, and what choice should be made to cam1:ShutterMode to make use of them?

 

The cam1:ShutterOpenDelay is generally used with external shutters that are controlled by EPICS PVs.  It is a part of ADCore.  It can also be used with detectors that have mechanical shutters controlled by the vendor API.  I don’t think it is useful in this case.

Hi Mark,  thanks ....

Steve, please be specific about what PV you are referring to.  Do you mean $(P)$(R)ShutterOpenDelay, $(P)$(R)ShutterCloseDelay, or some other PV with the string “delay” in it?

Hi, can anyone explain the usage of delay for Mantra cameras using the vimba driver?  the EDM screen says units are seconds - is that correct?   I  set this to a value that should not acquire the beam, but it still does so.

 

 

 

Thanks in advance
