Re: Issues in MCA module with XFlash detector

Hi Abdallah,

Are you communicating with the XFlash over a serial port or over their QM100 high-speed interface?

If it is over a serial port then you should enable asynTrace to see the communication stream.

Subject: Issues in MCA module with XFlash detector

 

Hi

 

We have the MCA module running on a Windows 10 machine to control the XFlash detector from Bruker. We started to face the following issues:

• When the IOC starts, the state is always acquiring without pressing the start button.
• The buttons to erase/stop/start the acquisition have no effect, they do not stop or start the acquisition.
• The real time and live time show weird values on startup, like in 10s or 100s. of seconds.
• If I wait long enough, the acquisition stops but pressing the start button again, say for a real time of 1 second, it starts acquiring for fraction
  of a second and then freezes, nothing is progressing.

 

Despite what is mentioned, the IOC log shows no error messages. The Bruker software seems to acquire just fine, but not tested thoroughly. We even

Installed the IOC on a different laptop and a PC and still the same behavior. Any idea on what might went wrong with the detector or IOC?

 

Best Regards,
