== Stopping SiTech Software ==
If one of the SiTech GUIs hangs or reports a comms error, the easiest fix is as follows: 1. Close to close all GUIs in this order, using the x in the top left-hand corner of each: i. ObservatoryControlSAAO.exe; ii. DomeControlTCP.exe, both left and right SiTechRotatorTCP.exe and SiTechFocuserTCP.exe in any order; iii. ServoSCommunicator.exe iv. SiTechExe.exe
# ObservatoryControlSAAO.exe;
# DomeControlTCP.exe, both left and right SiTechRotatorTCP.exe and SiTechFocuserTCP.exe in any order;
# ServoSCommunicator.exe
# SiTechExe.exe
Then follow the instructions on [[#Starting SiTech software| starting SiTech software]] to restart.
