ICS/DAS startup

The Instrument Control System (ICS) and Data Acquisition System (DAS) are integrated systems, and are accessed through one single XTERM window running an ordinary UNIX shell. This user interface runs on lpss10, whereas the actual data acquisition is controlled by lpss12. You are advised not to use lpss12 for anything else than running the system, as this could seriously interfere with the data flow.

If you haven't started up the TCS then do that first! To startup the system login to lpss12

         login: jktobs
         Password:
                           (the current password is posted in the control room)

and type

         jktobs@lpss12> obssys

in the pink window that popped up. The obssys command lets you choose which system version to run; the white board or your Support Astronomer will tell you what is the appropriate system to select. Then type

         jktobs@lpss12> startobssys

to startup the system. From this point, you should not have to issue any commands in the XTERM window on lpss12.

Then login to lpss10 (same user, same password) and again type

         jktobs@lpss10> obssys

and enter the same system version number as on lpss12, and type

         jktobs@lpss10> startobssys

in the pink window that popped up. This will bring up 5 extra windows:

- the TALKER window, which lists system messages that can be useful if something goes wrong,

- the LOG window, which lists the entries in the automated log file,

- the CCD-MONITOR window, which displays the status of the CCD,

- the TELESCOPE INFODISP window, which displays the status of the telescope,

- the JKT-MIMIC window, which displays a simplified mimic of the light path in the JAG.
You can set the CCD readout speed (standard/quick/turbo) by typing

         SYS> quick

which you have to do every time the SHUTDOWNOBSSYS command has been used. To set the full readout window use

         SYS> window 1 0 0 0 0

or, to set the window to the central 500x500 pixels of the SITe2 chip use

         SYS> window 1 500 500 262 262

where the last two arguments are the X and Y offsets. Type

         SYS> zeroset mainfilt

to initialize the JAG filter wheel.
