Fixing "Inactive" Spectrometers

If the Acquisition Status window (Acqstat) shows Inactive you should try the following steps to revive the spectrometer

If the spectrometer is Inactive

  1. wait two minutes.
  2. note in the logbook what the symptoms are and what you were doing or trying to do when the problem occured.

If the spectrometer remains "Inactive" after two minutes

  1. open the terminal window named "console" by right clicking on the arrow above "disk/cpu" icon on the Workspace Manager and selecting console from the list.
  2. type 'su acqproc' (without the quotes) in the console window.
  3. hit return if you are asked for a password
If the response is Starting 'Expproc' 
  1. check the acqstat window, the console should now be "Idle"
  2. If it is still "Inactive", start over from the beginning.
  3. If it is "Idle", note in the logbook what you did to fix it and you are done!
If the response is Killing 'Expproc':
  1. type su acqproc hit return if asked for password
If the response is Starting 'Expproc':
  1. check the acqstat window, the console should now be "Idle"
  2. If it is still "Inactive", start over from the beginning.
  3. If it is "Idle", note in the logbook what you did to fix it and you are done!

If the the response is Starting 'Expproc'

Channel 1 on console already connected to another process
Channel 2 on console already connected to another process
etc...
  1. type 'su acqproc' (even if you can't see what you are typing)
  2. hit return twice
  3. the stream of error messages should now stop.
  4. now you will have to reset the console
  5. On the MERCURY 300:
    1. open the black glass door on the front of the console (twist the knob on the right and pull)
    2. press the big red button.
  6. On the INOVA 400, 500 and 600:
    1. Open the left side of the console by pulling on the door.
    2. About two thirds of the way up on the far left side, set back from the front of the console you will see a board with a Motorola logo on the lower handle.
    3. Press the white button labelled RST on the "motorola" board once.
    Back at the computer
  7. wait until you see " 100 MBs Full-Duplex Link up" in the window named "console"
  8. type 'su acqproc'
  9. you should see Starting 'Expproc'
  10. wait until you will see a message declaring that the
    Acquisition system is ready at 300 (400,500) MHz
    .
  11. start VNMR, the console should now be "Idle"
  12. If it is still "Inactive", start over from the beginning.
  13. If it is "Idle", note in the logbook what you did to fix it and you are done!
