Subject: LGS How To for the twiki

Here is the how to for the lgs software. It doesn't have the complete command set in there but has everything the
LGS operator will need.

This is the first draft and will change a bit as the changes to the temperature (disable most likely) are implemented.

PS - When I send this to Renu she said it all came in as one big paragraph. It is formatted nicely on my screen. Let me know
if it is hosed.
				Palomar Laser Guide Star (LGS) Monitor and Control System
						
							User's Guide
		
							 Version 1.0

1.	General Start up and Stop processes

	The general start up of the LSG Monitor and Control systed is to use the
	start and stop scripts located in /home/lgsusr on the LGS computer.
	To execute the scripts, run the following commands:
	
	To Start the LGS system:
	/home/lgsusr: StartLGS.sh [-debug] [-gui]

	The -debug flag will send debug messages to the terminal screen for monitoring. 
	The -gui flag starts the LGS Monitor and Control Graphical User Interface (GUI).
	
	To Stop the LGS system:
	/home/lgsusr: StopLGS.sh

1.1	Command Summary

	The following is a summary of the LGS Monitor and Control command set. The detailed
	description and syntax for each command are provided in subsequent sections.

	Temperatures:
	------------	

	From the command line on the gui, it is possible to request any data related to the
	McShane Temperature Control Box. The most recent data is displayed in the GUI but
 	can also be requested on the command line.
	
	Syntax:
	reqtemp <unit number>

	Where:
	<unit number> = 1 - 6

	Syntax:	
	settemp <unit number> <temperature>

	Where:
	<unit number> = 1 - 6
	<temperature> = desired temperature (C)

	Syntax:
	disable_unit <unit number>
	
	Where:
	<unit number> = 1 - 6

	Photo Diodes:
	------------

	From the command line on the gui, it is possible to request any data related to the
	photo diods controlled by the "brick" built by Chris Shelton. The most recent data 
	is displayed in the GUI but can also be requested on the command line.
	
	Syntax:
	reqdiode <number>

	Where:
	<number> = 


	Record Data:
	-----------

	From the command line on the gui, it is possible to request the LGS Monitor and Control
	System to record data to a Palomar AO data recorder.

	Syntax:
	set_record

	The recording rate can also be set from 1 to 20 Hz. Currently it defaults to
	1Hz upon start-up. 20 Hz is pushing the capability of the serial devices.

	Syntax:
	set_log_rate <rate>

	Where:
	<rate> = desired logging rate (1 - 20) Hz
