-The Filter provides two CRDC packets: one for CRDC1 and one for CRDC2. Each CRDC packet is divided in two sub-packets: the "Raw" sub-packet with information about the pads energies (encoded in the [[S800 USB DAQ data format#Tag 0xCFDC: XLM72V crdc1 pad readout module|CRDCs XLM72 modules]]), and the "Anode" sub-packet with anode energy and time information encoded in the CRDCs [[S800 USB DAQ data format#Tag 0x7167: Phillips 7164 ADC module for CRDC anodes (energies and TAC)|Phillips ADC]].  +The Filter provides two CRDC packets: one for [[Detectors|Cathode Readout Drift Chambers (CRDC)|CRDC1]] and one for [[Detectors|Cathode Readout Drift Chambers (CRDC)|CRDC2]]. Each CRDC packet is divided in two sub-packets: the "Raw" sub-packet with information about the pads energies (encoded in the [[S800 USB DAQ data format#Tag 0xCFDC: XLM72V crdc1 pad readout module|CRDCs XLM72 modules]]), and the "Anode" sub-packet with anode energy and time information encoded in the CRDCs [[S800 USB DAQ data format#Tag 0x7167: Phillips 7164 ADC module for CRDC anodes (energies and TAC)|Phillips ADC]]. In the following, we describe the structure of the packet provided by the Filter for each CRDC.
