COMMANDING
				----------


		    SENDING COMMANDS TO SPACECRAFT DURING NRT

- Monitor the health of MDI by checking the following screens:

   Health Monitoring Web Pages: http://mdiems.nascom.nasa.gov/health_mon/ 
   Flight Status (screen 12)
   xmonseq (on unix) - shows what framelist is being executed by sequencer
   xmonlog (on unix) - displays operators log
   mon_sci5k (in IDL) - displays low rate data and loi images
   mdi_display (in IDL) - displays high rate data products
   iperr_sea (in IDL) - gives list of IP Errors
   plots of IP Errors (on web or in IDL using rtplot)
   DEP Status (on toolchest)
   Power & Temperature (on toolchest)
   General Telemetry (on toolchest)

- Prepare instance 

  the script lists the commands to be sent

- Bring up EGSE Command Console
 
  Start EGSE to get Main EGSE Console then hit command button for Command
  Console and make sure you are in the flight directory by highliting "CD" on 
  the sidebar under the word "Display ->" and look at the directory listed
  there.  If you are not in the flight directory, highlight the
  "New CFL dir: flight" and hit return or send to switch into the flight 
  directory

- Hit start button 

  This requests commanding authority from the ECS, and once permission to 
  command is granted by a message on the screen from the ECS, continue on

- Highlight "PROCS" on the sidebar 

- Find the command you want in "PROCS". If it is in perform status it is 
  ready. If it is in compile status then compile the new commands by typing
  compile <procedure name> or comp -n (this compiles the newest procedures,
  but takes longer), then hit the PROCS button again to reload the listing of
  the procedures and then the status of the procedure should have changed from
  compile to perform status 

- Hit return or click on the "SEND" button to send the command

- Enter the initials of the operator and the command just sent into an
  emacs window, to send the comment to the ops log hit <Cntl>-x <Cntl>-a 

- Take the time from the daily log and put it into the instance file as a 
  start time

- Redo this procedure for the next command in the script
 
- When you are all done commanding, hit the stop button



			    TROUBLE SHOOTING

- If MDI_ACQ quits (it collects the data for us)

  hit shutdown

  type EGSE in shell window to restart it

  call EOF and have them reconnect telemetry on Socket 0 (low rate) and
  Socket 1 (high rate)

  fill out a GSDR on the web (found on SOI page under documentation) and hit
  MDI Ops Forms, then hit GSDR)

- Stopping Procedures while commanding

  If the procedure needs to be HALTED, for example if there is a pause in
  the NRT link, click on HALT.

  If the procedure needs to be aborted,first halt it then type abort all 
  in the MDI EGSE Command Select command window.
