== P2.3 TCS communication test == • **Phase** : 2 • **Status** : Draft • **Category** : Daytime testing (functionality and operability) (C2) • **Recurrence** : after instrument installation at telescope platform • **Duration** : 1 hour(s) **Description** • Communication with the LBT TCS is tested, with the aim to verify that the interface with TCS works as expected. **Prerequisites** • All electronics and services up and running. **Procedure** • Test all the TCS functionality needed by SHARK-NIR, which are detailed in AD2. • Check if the fits-writer is receiving all the right values from the LBT TCS. • Check if the derotator trajectory is received from the LBT TCS. The final testing of the trajectory with optical feedback will be done during the night time commissioning. **Success criteria** • Connection to LBT TCS working well. All the test results are successful. • Fits-writer is receiving all the right values from LBT TCS. **Notes** **LBTO support** **Associated SHARK-NIR personnel** • JF, LM, MdP, MM (from AZ), Dino? **Date performed and by whom**
