 ==== Timing setup ====
+At present, there are three electronic "sources" with time information for ToF calculation: ORTEC TACs, Phillips TDC, and Mesytec MTDC. Some background information can be found [[Timing|here]].
-Overview:
-  * There are three electronic "sources" with time information for ToF calculation: Tennelec TACs, Phillips TDC, and Mesytec MTDC.
   * Although the ToF reference ("start") in all the ToF modules is given by the FP scintillator E1 up, the electronic path from the detector to each module is different (see {{:wiki:s800electronicstschematics-to20150907.pdf|main electronics diagram}} for more details)
   * Before going to the ToF modules, the OBJ and XFP signals are sent to a CANBERRA CFD 454 CFD in data U6 from the data-U6 patch panel (OBJ: patch panel #54, XFP: patch panel #1). (The exception is the OBJ signal into the MTDC)
