Dear Mark，

Sorry for late reply. The fiber-optical was broken. We haven't got time to do the test. We are running the IOC on another machine, not on the marccd software itself. This marCCD is a spare detector which haven't been use for last year. We are doing the test for future use. We will test it again after the fiber problem been solved. Thanks a lot.

Best Regards,

Wenming

&gt; 
&gt; What machine are you running the IOC on?  Is it the machine that is running the marccd software itself, or is it some other machine?
&gt; 
&gt; 
&gt; Have you tried saving a file using the marccd software itself, i.e. without using EPICS, to see if that works?
&gt; 
&gt; 
&gt; The marccd server logs all of the activity when it communicates with EPICS.  Have you looked at those messages for any errors?
&gt; 
&gt;

&gt; Dear Mark,
&gt; 
&gt; Thank you very much for your reply. I tried to collect with /home/marccd, and /home/marccd/Documents, It still didn't work. The /home/marccd/Documents should have write permission, because we had written data in this fold before with BluIce.
&gt; 
&gt; Best Regards,
&gt;

&gt; &gt; Hi Wenming,
&gt; &gt;
&gt; &gt;
&gt; &gt; You are telling marccd to save files to /home/.  I suspect that the marccd account does not have write permission to /home/.  Try writing to /home/marccd, or some other directory where marccd does have write permission.
&gt; &gt;
&gt; &gt;
&gt; &gt; Mark

&gt; &gt;
&gt; &gt; Dear Sir/Madam,
&gt; &gt;
&gt; &gt;
&gt; &gt; I installed and configured the ADmarCCD module on CentOS7.  The installation looks succesed. But it always shows detector state error and writing status error in MEDM gui as shown in the following picture. Would you please give me some suggestion on how to figure out it. Thanks a lot.
