 +  * **Energy values** 
 +The energy (from the Phillips 7164H ADC module) is given by a series of words that look like:  
 + 
 +^  ^^^ Ch ^ energy  ^^^^^^^^^^^| 
 +| 0 | 0 | 0 | X | X | X | X | X | X | X | X | X | X | X | X | X | 
 +| 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 | 
 + 
 + 
 +Where Ch is the segment number (from 0 to 15, being segment 0 the most upstream). The Filter gives an energy word for each segment as long as **energy** is greater than 0. 
 + 
 + 
 + 
 + 
 +==== CRDC packets ==== 
 +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]].
