A Simple Guide to Running Taurus
---------------------------------
This assumes you are not using an Etalon.   You need expert assitance (i.e.
Keith Taylor) if you are.  This also assumes that you are running Taurus
from the AAT40A Observer account using an X device.


Physical Setup
--------------
This should be done by Site staff but they may forget the control room
connection of the Panic Button to the 50 way connector.  Ask for the 
Panic Button and enusre it is plugged into a 50 way connector.  If not,
remind the Site technical staff.    Both the control room panic button and
the small panic button in the Cass cage must be connected.

Software
--------
Log into the Vax observer account from an X terminal or Sun console.
Type
	$XON node

If and only if running the FOP module using the polarimetry software
	$SYSTEM POLCT

If you wish to change the version in use
	$VERSION version_name

where node is the X Terminal or sun name. Type
	$RVTAURUS CCD_n

where n is 1 or 2.

The Sms screen will come up on the logging terminal and the CCD system will
appear a bit later.

On an sms menu, sub menu's are suffixed by a colon (:), parameter entry
fields by a dash (-) and commands have no suffix.

Hit "Return" to enter a sub menu or a parameter entry field perfrom an action 

Use PF1 to exit a menu or parameter entry and perform the any associated action
Use PF2 to exit a menu or parameter entry without doing the action.

Parameter fields are either editable (using normal edit keys - Ctrl-U deletes
the entire entry) or enumerated (use left/right arrow keys to select).  Use
up/down arrow keys to move to the field.

You can get help on most menu items by hitting "?".  A second "??" will
often get more detailed help.

When the Taurus startup menu appears, you must first enter the "Startup" 
parameter field.  Normally, the entries where will be correct and you should
just hit return.  The Taurus status display will now appear in its own window.
When Taurus has initialised, the other menus will be enabled and "Startup"
disabled.

If you exit the top level menu, then the SMS system will shutdown (although
Taurus and the CCD will be left running).  You can restart SMS by typing
RUNTAURUS.    You will need to go though the Startup item again.


Taurus menus
------------
    setup - Used for setting up taurus.  In addition to the standard
	close_shutter entry, it has two sub menus.

	control - Used for controlling Taurus.  Note that  "access_etalon" 
		moves the specified  etalon position to the access position
		and move the pupil filter such that the access hole is in
		the access position.   Note, if the access doors are open then
		you cannot move the wheels or open the shutter.   The status
		of the door is displayed on the Taurus status screen.   To
		override the interlocks, use the "interlocks" entry.

	configure - Used to save and restore definitions - such as filter
		position/name relationships.   To name a filter, use
		"def_wheel_pos", selecting the wheel and position number.
		After this is done, the filter will be displayed using the
		name (you can still enter the number when selecting filters).

		Use "save_wheel_defs" to save the current definitions.  Default
		file name is TAU_FILTERS.TFD.  The file can be edited with	
		a text editor if desired.

    run - Run control options.  Probably not of any interest unless an
		etalon is being used.
	
    shutter - open or close the shutter

    close_shutter - quick close of the shutter

    operate_ccd - If enabled, provides a menu to run the CCd system.  Note,
		arguments will be prompted for.

    panic_recover - Use if the panic button has been hit.   The status screen 
		will display an appropriate message if the button has been
		hit.

   refresh - refresh the status display screen.  Use ctrl-r for the SMS
		screen

   maintenace - password protected menu for software maintenance operations.

   finished - Prompts for shutting down Taurus.

Possible Problems
-----------------
Ccd system does not come up - You have not done  "XON".

Taurus Status display does not come up  (assuming CCD system has).   
	1. You have not correctly used the "startup" menu - try again.  
	2. The Taurus micro is not connected or the lat server port is hung.  
		Ensure connections are made in the cass cage and have someone 
		(e.g. Bob Dean) forcefully log out the terminal sever port 
		assocaited with TAURUS_SIF.  

A single Command error on startup - ignore this.

Taurus Iris motor timeouts - sorry, the iris motor is stuffed.   It will work
	some of the time.   We generally try to leave it open (15).

Takes a long time to move the Focal plane filter - This is ok, it takes a while
	to ensure Focal Plane tilt is nulled.
