<div style="background-color:#FFFFFF">Dear Greg and Pablo,<br>
<br>
the EPICS embedded IOC is not changed between version 2.0.1 and 2.0.2 so the fact that Pablo test with 2.0.1 and the test made by his coworker did not match lead me to think that the issue could not be in the IOC but elsewhere. Also the changes saw only using
the CAEN Web server seems to confirm that the unexpected changes are happening in the mainframe/boards and not in the IOC.<br>
<br>
There is only one point that doesn't sound good to me and it is the point 2, if I well understood Pablo said that the values showed by GECO was not the same showed by the EPICS client, is it correct, did you see a channel ISet value different from GECO to EPICS
client?<br>
<br>
I think the problem is related to the boards but we have to investigate and actually I don't have here these two models available so I need you help on doing the tests. I would like to know if the problem still present if you use only one board at a time (using
GECO and EPICS software together). Can you try?<br>
<br>
It would be usefull if you can share with me a video showing the issue so I can better understand how solve it.<br>
<br>
Best Regards,<br>
Alberto

I realize you are still on holiday. Please do not feel obliged to answer this immediately!<br>

In copy you will find Pablo Rojas from JLAB. Pablo is the customer we've been discussing who is experiencing some communication problems with his SY4527 mainframes and EPICS.<br>
<br>
Below he describes the steps he's taken and symptoms he is seeing. Please take a look and let us know what the next step should be?<br>

<br>
</font><font face="Times New Roman"><font face="Times New
Roman">Regarding the FW Revision 2.0.1, we can definitely give you that file to use/try. This week the CAEN office is closed, but I should be able to get it to you next week.<br>
<br>
</font>I've heard back from the engineer who manages the CAEN software division and is also responsible for EPICS integration. He has not been made aware of any outstanding issues with EPICS and any version of the CAEN HV Firmware. He also mentioned that
EPICS service are managed by by the IVoCS upgrade, not by the firmware upgrade, which is making him wonder as to the actual root of the issue.<br>
<br>
Is there any chance you could provide me with more details regarding this problem? We can try the older Firmware but we'd also like to try to better understand the issue.<br>
<br>
Many thanks,<br>
