       * For each ToF, SpecTcl will search the hit number that fits in the selected region. The new MTDC ToF parameters are **s800.fp.vmetdc.mtdc_rf**, **s800.fp.vmetdc.mtdc_obj**, and **s800.fp.vmetdc.mtdc_xfp**        * For each ToF, SpecTcl will search the hit number that fits in the selected region.

-  * If necessary, adjust delays: +  * If necessary, adjust delays of Phillips TDC (in principle, the TACs delays don't need to be adjusted): 
-      * Using the [[S800 DAQ tools#Trigger GUI|ULM trigger GUI]] assign TDC-start to one of the Inspect Trigger channels and trigger the scope with it +      * Using the [[S800 DAQ tools#Trigger GUI|ULM trigger GUI]] assign TDC-start to one of the Inspect Trigger channels (patch panel #55 - #58) and trigger the scope with it (be aware that the TDC-start signal seen in the scope has an additional delay of ~200 ns due to the length of the cables between the ULM module in S3 vault and dataU6 patch panel) 
-      * Select the timing signals (Delay inspect channels) E1 up, OBJ and XFP with the [[S800 DAQ tools#Delay Window|Delay GUI]] and look at them in the scope +      * Connect the XFP and/or OBJ signals going to the Phillips TDC (via cables plugged to patch #66 and #67, respectively) to the scope 
-      * Adjust the TDC delays of OBJ and XFP using the delay boxes connected to the CANBERRA CFD 454 in data U6 +      * Adjust the TDC delays of OBJ and/or XFP with respect to the TDC start, using the delay boxes connected to the CANBERRA CFD 454 in data U6 
-      * Adjust the TDC delays of E1 up, down using the Delay GUI +      * Be aware that the after adjusting OBJ and XFP delays in the scope, the signal will be further delayed by ~200 ns due to the length of the cable between dataU6 patch panel and the Phillips TDC in the S3 vault. 
-      * In principle, the TACs delays don't need to be adjusted +      * Check the corresponding ToF spectra in SpecTcl to confirm that the timings are properly adjusted.
  
   * Check the efficiencies of the Phillips TDC, TACs, and MTDC for the OBJ-FP and XFP-FP ToFs:   * Check the efficiencies of the Phillips TDC, TACs, and MTDC for the OBJ-FP and XFP-FP ToFs:
