The serial number of the rotator controller is A603G14W, so this confirms that the rotators are communicating on port ttyUSB1. If the above command gives you a different serial number, edit the command to try each port from ttyUSB0 to ttyUSB5 until you find A603G14W. Now go to the ServoSCommunicator GUI and select the Rotators tab. In the dropdown menu, select the appropriate port - in this case ttyUSB1. Go to each of the Left Rotator GUI and the Right Rotator GUI and click on the pink warning complaining of no comms. If the warning doesn't clear, shutdown and restart all SiTech. ServoSCommunicator should wake up with the ttyUSB1 port selected, and communications to the rotator GUIs should be restored.
7. '''The telescope won't slew'''. First check that the telescope is unparked and that the target is within the visibility window. If those things are fine, the telescope may have triggered the hardware azimuth limit switch. This sometimes happens if the telescope is at azimuth ~165. Go to the SiTechExe GUI (the long, thin one) and at the top of the Scope tab, check if any of the arrows are red or orange. If they are, click the opposite arrow a few times to move the telescope out of the limit. If the motors are in "blinky", you may need to click the button at the bottom to switch the motors to automatic.
