====== Electronics, patch panels, and hardware ======

===== data-U6 (south end) =====

  * **Electronic location:** two racks that contain all the electronics and patch panels 

  * **Oscilloscope TEKSCOPE11**
        * Use: [[Detectors|S800 detector]]/timing diagnostics
        * Location: left rack on shelf below beamstop control at Image 3 of [[http://www.nscl.msu.edu/exp/devices#a1900|A1900]] 
	
  * **NMR Oscilloscopes**
        * Use: NMR resonances display
        * Location: upper two shelves on right electronics rack

  * **NIM bin** 
        * Location: below NMR scopes in right electronics racks
        * Use: Canberra HV supply for [[Detectors#Plastic scintillators|Object scintillator]] (see rightmost module in figure below) and Tennelec HV supply for the electrostatic gate of the CRDCs

  * **Top patch panels (top of right rack)** 
        * Cables 1-20: to data-U1 (signals from [[http://www.nscl.msu.edu/exp/devices#a1900|A1900]] detectors) 

{{:wiki:patch-panel1-du6.jpg?500|Patch panel 1 in data-U6}}


  * **Top patch panels (top of left rack)** 
        * Cables 1-10: to the [[Stations#Object|object station]] (not connected in vault; maybe these go to an old target location in the transfer hall)
        * Cables 11-20: to the [[Stations#Object|object station]] 
        * Cables 21-25: to the [[Stations|intermediate image station]]
        * Cable 26: missing
        * Cable 27-50: should go to the [[Stations|target station (pivot point)]] (mostly not connect in vault)

  * **Middle patch panel (middle of left rack)** 
        * Cables 51-70: to the [[Stations|focal-plane station]] 
        * SHV cables 1-2: to the [[Stations|object station]] 
        * SHV cables 6-10: should go to the [[Stations|intermediate image station]] (apparently not connected in vault)
        * SHV cables 11-20: to the [[Stations|target station (pivot point)]] (not connected in vault)

  * **Bottom patch panel (middle of left rack)** 
        * Cables 71-111: to the [[Stations|target station (pivot point)]]  

===== S800 Focal Plane (top level of S3 vault) =====

  * **Electronics location:** bottom of right rack inside cabinet located on top level of S3 vault on north side of the focal plane

  * **Patch panels:**
        * SHV Cables 21-30: to data-U6 
        * Cables 51-70: to data-U6
        * Cables 91-110: to the [[Stations|target station (pivot point)]]

{{:wiki:patch-panel-s3.jpg?500|Patch panel 3 in data-U6}}

===== Pivot point (bottom level of S3 vault) =====

  * **Electronics location:** one rack on bottom level of S3 vault on south side of final analysis line triplet near stairs to middle level

  * **Patch panels**
        * Cables 75-110: to data-U6
        * Cables 70-80: to the [[Stations|object station]] 
        * Cables 81-90: to the [[Stations|intermediate image station]]
        * Cables 91-110: to the [[Stations|focal plane station]]

===== Intermediate Image (accessed via middle level of S3 vault) =====
  * **Electronics location:** one rack above intermediate image box located on west end of top level of S3 vault

  * **Patch panels** (in electronics rack on top level of S3 vault)
        * Cables 21-25: to data-U6
        * Cables 81-90: to the [[Stations|target station (pivot point)]]
{{:wiki:patch-panel-image.jpg?500|Patch panel in intermediate image plane.}}


===== Object position (access via middle level of S3 vault) =====
  * **Electronics location:** under first triplet in analysis line

  * **Patch panels** (mounted on object box support under object box)
        * Cables 11-20: to data-U6
        * Cables 71-80: to [[Stations|target station (pivot point)]]
        * SHV cables 1-2: to data-U6
