<div class="PlainText">Hi folks,<br>
<br>
Aaron and I had a brief email exchange earlier in the week, but I also<br>
had some more general follow-up questions to the DSG group. The NPS<br>
Collaboration is getting to the point where the controls noted below<br>
will be required, even after all of the delays associated with the PMT<br>
noise issue.<br>
<br>
We will need working software within a few weeks to continue the<br>
program. I understand that things are being worked on, but I'd like<br>
a rough, but meaningful, timetable for the development work noted below<br>
to help us plan on our end.<br>
<br>
o Phoebus HV GUI isn't quite ready to go.<br>
- The Instructions here aren't enough to run the GUI<br>
<a href="https://wiki.jlab.org/cuawiki/index.php/NPS_Controls#Phoebus_HV_controls">
https://wiki.jlab.org/cuawiki/index.php/NPS_Controls#Phoebus_HV_controls</a><br>
- I presume that works from the cdsg account, but that is not the<br>
account that we will use.<br>
- Can you add instructions on how to install a copy of that software<br>
in a different account (provide a tarball, etc.)<br>
<br>
o Chiller controls: Please add documentation to the wiki on how to<br>
configure and run the relevant software<br>
<a href="https://wiki.jlab.org/cuawiki/index.php/NPS_Controls#Chiller">https://wiki.jlab.org/cuawiki/index.php/NPS_Controls#Chiller</a><br>
<br>
o Thermal Readbacks: Please add documentation to the wiki on how to<br>
configure and run the relevant software<br>
<a href="https://wiki.jlab.org/cuawiki/index.php/NPS_Controls#Thermal_Readbacks_.28Keysight.29">
https://wiki.jlab.org/cuawiki/index.php/NPS_Controls#Thermal_Readbacks_.28Keysight.29</a><br>
<br>
o Can you provide an ETA on the LV controls software?<br>
- I had understood there was a GUI for the same Weiner MPOD system<br>
running in Hall A associated with the GEMs. Can that be adapated?<br>
<br>
o Can you provide a status update on the LED controls<br>
- Do you have a testbed established using the boards and drivers you<br>
in your possession?<br>
- Have you been able to take to the boards with the low level code<br>
Bryan Moffit, William Gu, et al have provided?<br>
<br>
All the best,<br>
-- Brad<br>
