42 +* **Where is the GOTTHARD GUI:** FLASH2 - Panel: Infrastructure tab → Miscellaneous tab → FLASH2 GOTTHARD ctrl button
43 +* **Never change a running system:** Do not change parameters while the Detector is running/taking data, The detector will crash.
44 +* Furthermore the module will crash if recieving to much light (e.g. illuminating with flash light during data dating.
45 +* **Checking/switching server:** The server is reachable from the GOTTHARD GUI (lower left corner find the status of the server PC "hasfl2det01") click it to open server/watchdog control. The server is otherwise found under FLASH.SYSTEM → HASFL2DET01.WATCH. Open control of SVR.GOTTHARD (for start/stop/reboot)

50 +** soft reboot: 1. open console on linux DESY PC, 2. type "telnet (Hostname/IP)" e.g. "telnet cfeld-gotthard02" , 3. you are logged on the GOTTHARD module as /root, type "reboot", 4. wait until server/GUI has reconnected to the module
51 +** hard reset: power down the GOTTHARD, wait some seconds, Repower the module, wait for reconnection to server/GUI
52 +* **In case of a crashes** (no data taking, no reaction on input: Reboot the detector) or if GUI input returns error: Check connection (Power/Data), check GOTTHARD server
53 +* **Permantent operation:** Activate check box for continous run to trigger automated restart of the module after reaching the set number of short or after sefl-stopping due to hickups. The restart needs about 1-2 seconds. During this time no data is taken.
54 +* **Background**: Check "Take" stores the actual detector image~: Uncheck this again. Than this stored image is online subtracted from all images in the GUI when checking "subtract". The DAQ only stores raw data (NOT the background subtracted images)

59 +* Do not change the delay in the GOTTHARD GUI. The Alignment to the FEL pulses are done by adjusting the FLASH trigger: FL2EXP1/RTM.TRG6, it can be opened from the GOTTHARD GUI or from FLASH2 → Beamlines → FL26 → Exp. control → Patch Panel26-2 → MTCA Trigger 2
60 +* Exposure range is 2**00ns <  Exposure < ~~1/3 * Frame periode**
61 +* The periode is:** 9968ns for 100kHz, 4984 for 200kHz, 1993 for 500kHz**
62 +* The number of** frames must be lower than 125, for stable operation 120**
