To add HV settings configurations for proper monitoring and mapping:
+
* Control GUIs [[Control_GUIs_Doc_Portal|Portal]]
* Log into aslow@adaq3 (using the adaq password
+
* Most up to date (but not necessarily correct): [https://hallaweb.jlab.org/tech/Detectors/public_html//hall_a/controls/ioc_portserver_reboot_locations.htm reboot locations]
* Run the hvs [right/left] command in the ~/slowc folder
+
* [[HVgui]]
** Use: Tools->Map Configurator, and then compare the voltage maps with the displayed voltages to make sure you are looking at the right ones
+
* [[Detectors]]
If you need to add your own configuration that isn't already one of the available maps
+
* Edit the ~/RIGHT/[whatever].map to contain the information you need (which requires that you know what HV cards your channels are plugged into, see the other maps for examples)
+
* Then do: Tools->Add/remove frame list->Cancel->Update Connections, which updates the map list
+
If the HV control GUI doesn't load, then you need to log into pi@rpi7, with Bob's rpi password, then run ./start_hv, and if that doesn't work, you will need to make sure the cron job is running in the background (./scripts/start_hv_cron) and then continue using aslow@adaq3's hvs command to proceed.

The SAMs are in rpi7:2001 port, S4 slot, L0.0->L0.7 channels
 
  
The SAM wired connections are established as indicated in this [[:media:SAMs_connections.pdf|PDF]] (but Actually, there is an error; SAM4 and SAM8 are connected to KDPA001 not KDPB001).
 
  
Devi made some initial pedestal studies: see [https://ace.phys.virginia.edu:80/HAPPEX/3607 HAPLOG 3607], and more recently, see [https://ace.phys.virginia.edu:80/HAPPEX/3617 3617] and [https://ace.phys.virginia.edu:80/HAPPEX/3618 3618]
