 The Filter parses and re-formats information from the [[Detectors#Tracking Parallel Plate Avalanche Counters (TPPAC)|Tracking PPACs]] encoded in the [[S800 USB DAQ data format#Tag 0x5870: XLM72V tracking ppac readout module|XLM72 TPPACs module]]. The new packet includes both TPPACs; its structure is very similar to that from the CRDCs. The Filter parses and re-formats information from the [[Detectors#Tracking Parallel Plate Avalanche Counters (TPPAC)|Tracking PPACs]] encoded in the [[S800 USB DAQ data format#Tag 0x5870: XLM72V tracking ppac readout module|XLM72 TPPACs module]].

 The **connector** number is defined between 0 and 3, and it is related to the pad number (**pad**). The value 0 refers to the first 64 pads, and correspond to the strips in the dispersive direction of the first TPPAC. The value 1 is for pads between 63 and 127, and includes the strips in the non-dispersive direction of the first TPPAC. The value 2 corresponds to pads between 128 and 191, which are associated to the strips in the dispersive direction of the second TPPAC. Finally, the value 3 corresponds to pads between 191 to 256, and covers the strips in the non-dispersive direction of the second TPPAC. The **connector** number is defined between 0 and 3, and it is related to the pad number (**pad**).
