-==== Trigger packet ====+===== Trigger packet =====
 The trigger packet includes a bit-pattern word (encoded  by the [[S800 USB DAQ data format#Tag 0x2367: Trigger module|ULM trigger module]]), with information about what sources triggered the event, and their corresponding time from the [[S800 USB DAQ data format#Tag 0x7186: Phillips 7186 TDC module for time-of-flights|Phillips 7186 TDC]]. The trigger packet includes a bit-pattern word (encoded  by the [[S800 USB DAQ data format#Tag 0x2367: Trigger module|ULM trigger module]]), with information about what sources triggered the event, and their corresponding time from the [[S800 USB DAQ data format#Tag 0x7186: Phillips 7186 TDC module for time-of-flights|Phillips 7186 TDC]].

-==== Time-of-flight packet ====+===== Time-of-flight packet =====
 The time-of-flight packet includes all the timing values encoded in the [[S800 USB DAQ data format#Tag 0x7186: Phillips 7186 TDC module for time-of-flights|Phillips TDC]] and the XFP-FP and OBJ-FP ToF from the ORTEC TACs encoded in the [[S800 USB DAQ data format#Tag 0x7167: Phillips 7164 ADC module for CRDC anodes (energies and TAC)|S800 Phillips 7164H ADC]].  The time-of-flight packet includes all the timing values encoded in the [[S800 USB DAQ data format#Tag 0x7186: Phillips 7186 TDC module for time-of-flights|Phillips TDC]] and the XFP-FP and OBJ-FP ToF from the ORTEC TACs encoded in the [[S800 USB DAQ data format#Tag 0x7167: Phillips 7164 ADC module for CRDC anodes (energies and TAC)|S800 Phillips 7164H ADC]].

-==== Scintillator packet ====+===== Scintillator packet =====
 The scintillator packet includes the energy (encoded in the [[S800 USB DAQ data format#Tag 0x4300: FERA module for plastic scintillator energies|FERA LeCroy module]]) and time (encoded in the [[S800 USB DAQ data format#Tag 0x7186: Phillips 7186 TDC module for time-of-flights|Phillips TDC]]) of the [[Detectors#Plastic scintillators|S800 FP scintillator]] signals. In the original configuration, there were 3 scintillators (E1, E2, and E3) which were later reduced to just one (E1) after the installation of the Hodoscope.  The scintillator packet includes the energy (encoded in the [[S800 USB DAQ data format#Tag 0x4300: FERA module for plastic scintillator energies|FERA LeCroy module]]) and time (encoded in the [[S800 USB DAQ data format#Tag 0x7186: Phillips 7186 TDC module for time-of-flights|Phillips TDC]]) of the [[Detectors#Plastic scintillators|S800 FP scintillator]] signals.

-==== Ion-Chamber packet ====+===== Ion-Chamber packet =====
 The Ion-chamber packet includes the energies of the [[Detectors#Ionization chamber|16 ion-chamber segments]] encoded in one of the [[S800 USB DAQ data format#Tag 0x7164: Phillips 7164 ADC module for ion chamber energies|Phillips 7164H ADC]]. The Ion-chamber packet includes the energies of the [[Detectors#Ionization chamber|16 ion-chamber segments]] encoded in one of the [[S800 USB DAQ data format#Tag 0x7164: Phillips 7164 ADC module for ion chamber energies|Phillips 7164H ADC]].

-==== CRDC packets ====+===== CRDC packets =====
 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. 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]].
