Changes
== Changes == Dec 2022: 1ms1 has been replaced with lesedis2 (username & password unchanged) and lesedi-nuc has been replaced with ioserver1. == SiTech == The SiTech software runs Lesedi on 1ms1 lesedis2 (="1-metre lesedi server 12", i.e. Lesedi's TCS PC). 1ms2 is Lesedi's backup machine. There is a main GUI for the telescope (SiTechExe.exe), a communications GUI (ServoSCommunicator.exe), a GUI for each rotator (SiTechRotatorTCP.exe and "SiTechRotatorTCP.exe left"), one for the secondary and tertiary mirrors (SiTechFocuserTCP.exe), one for the dome (DomeControlTCP.exe) and a GUI that communicates with each subsystem's software (ObservatoryControlSAAO.exe). All of these GUIs must be running for the telescope to function fully, and only one instance of each can be run at a time, else problems will arise.
'''Leave the SiTech software running at all times during normal operations. It is vital to ensure that no parameter is changed in any of these GUIs.'''
== Starting SiTech software ==
The software should be opened on lesedi-nucioserver1, by connecting by ssh to lesedis2 and running the software using the mono libraries. If in Sutherland, you can do this from the lesedi-nuc ioserver1 PC in the warm room, else if working remotely from Cape Town, VNC to lesedi-nucioserver1:
1. Open Remmina Remote Desktop Client, select "VNC" from the dropdown menu and double click on Lesedi_Nuc ioserver1 from the list of servers. Enter the password and the lesedi-nuc ioserver1 desktop will be displayed on the screen.
2. Look for an existing terminal on lesedi-nucioserver1, else open a new one, and log in to lesedis2:
ssh -Y observer@lesedis2.suth.saao.ac.za (you shouldn't need the full path from inside the network, just observer@lesedis2)
7. If you ever need to restart either ServoSCommunicator or SiTechExe, you will first need to close all the other subsystem GUIs, and reopen them in the order above.
8. If working in the dome, bundle all the GUIs onto the left-hand monitor (it makes it easier to find them if someone needs to VNC from a smaller screen) then minimise them - they won't need to be accessed during the night unless something goes wrong. If working in Cape Town, you can close the VNC session with lesedi-nuc ioserver1 by clicking the right-hand "Disconnect" button on the Remmina tool bar.
== Stopping SiTech Software ==
== Making a pointing model using SHOC ==
1. Open Remmina and VNC into lesedi-nucioserver1.
2. Make sure all the usual SiTech software is running and ready the telescope for observing, then in /home/observer/bin open the programme that connects to SHOC and run astrometry:
9. '''Save the model''' by clicking "Save Text Calibration File" on the Main PXP tab of the PointXP6 window. The naming convention is '''YYYYMMDD_SHOC_Right_NorthUp_150points.PXP''' for a 150 point model made with SHOC on the right-hand rotator tracking the parallactic angle. If you intend to use the model, '''also save it as AutoLoadRight.PXP''' (overwrite existing file) so that it is loaded automatically when selecting the SHOC port. The model file selected for each port is set on the Tertiary Mirror tab of the SiTech TCP Focuser GUI (currently /usr/share/SiTech/SiTechExe/AutoLoadRight.PXP - if you change this, remember to click "SAVE Settings" on the Configuration tab).
10. Close the Script, PointXP6 and Astrometry windows, the SiTechCamera GUI and CTRL-C in the terminal to stop running the astrometry programme. If going back to normal operations, stop all SiTech software and reopen from lesedi-nucioserver1, then do a "sudo systemctl restart lesedi" and "sudo systemctl restart lesedi-web" from lesedis2 and restart the autoguider software.
