RE: areadetector PV for pilatus3 retrigger and count-rate correction

Hi Mark,

 

This is for our pilatus3 X 6M, so within this manual https://media.dectris.com/user-manual-pilatus3-2020_GOKBotG.pdf. The specific commands are SetRetriggerMode and RateCorrLUTDir

Hi Keith,

 

Those commands are not supported in ADPilatus. 

 

I just searched this Dectris camserver document for the string “retrigger” and it does exist.

https://media.dectris.com/User_Manual-PILATUS2-V1_4.pdf

 

Where did you find the documentation on the retrigger command?

 

I do see the documentation on the Tau command.  ADPilatus currently only reads Tau, it does not allow setting it.

 

However, you can set it via the OPI screens as follows:

• In the screen pilatusDetector.adl open the Debugging/asyn record screen.
• Change the port on that screen to camserver (if that is what you called it in the startup script).
• Open the More/asynOctet interface I/O screen
• In the Output/ASCII screen type the camserver command.  You will see the response in the Input/ASCII field.

 

I just tested this typing “Tau” to read the current setting, and I received the correct response.

 

Mark

Are there PVs that exist for adjusting these parameters? Alternatively, since I know the specific camserver commands, is there a PV I can use to manually send strings to camserver? I noticed that there is a StringToCamserver_RBV, which piques my interest.
