====== Login on LN computer ======
The LN computer lives in the GRETINA net and doesn't know
about the outside world.

  * login on gateway machine nsclgw1.nscl.msu.edu
  * login as gretina on a2.gam (35.8.35.163)
  * login as ln on gln1 (10.0.4.11)

====== LN scripts ======
They are found in ~/scripts. The main LN program (gln_master) is a job
run by root and not directly accessible by the user. Interactions happen
via scripts. Most interesting is //run-gln-ui.sh//, the User Interface.
  ***run-gln-ui.sh**: User Interface, 'help' gives option 
  *run-send-alarm.sh: Add your email here for receiving alarms
  *run-log.sh: Add your email here for receiving logs
  *run-log2.sh: Add your email here for receiving logs after each fill      
  *run-log3.sh:             
  *run-send-alarm-wd.sh  
  *finish_fill.sh: script executed after fill attempt
  *run-gln-master.sh  
  *run-mail-que-view.sh                  
  *run-time-sync.sh       
  *run-backup.sh         
  *run-tlog-and-plot.sh
  *run-dlog-and-plot.sh      
  *run-mail-que-flush.sh  
  *run-view-master.sh: Output of the LN master process

====== LN configuration ======
The LN configuration file is found as ~/gln/gln.fig. It is //self-explanatory//. If this file got updated, use run-gln-ui.sh script and the command "load" in there. Note: After a "load" in the UI all detector fill schedules are gone! You need to do a "fill x y z after h:mm".   

====== ADC to channel mapping ======
Documentation for ADC mapping: {{:connections_1_.pdf|}}

  * ADC 1-4: Manifold overflow 1-4 (Manifold overflow at supply box Q1-Q4)
  * ADC 11-17: Fill overflow Q1-Q7 (Overflow input at supply box)
