 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]].

-===== Versioning system ===== 
-ATTENTION: This section needs to be updated!!!!! 
- 
-The detectors installed in the S800 and the data to be read from them often changes with the differing requirements of each experiment. This in turn impacts the details of the data format, and requires the use of a version number in order to be backward compatible. Subsequent changes to the S800 data acquisition will increment the version number of the data format and new configurations will be reflected in new packet tags. Documentation for these changes will be given here, in links accessible from the following table. The current version of the data format is indicated with a star. 
- 
-^ S800_VERSION ^ Notes ^ Current Version | 
-| [[S800_VERSION 0x0004|0x0004]] | Last version using the SBS readout system, up to end December 2011 | | 
-| [[S800_VERSION 0x0005|0x0005]] | First version to use the VM/CC-USB parallel readout system, beginning January 2012 |  | 
-| [[S800_VERSION 0x0006|0x0006]] | The S800_GALOTTE_PACKET is added for the Galotte MCP Object box detector | * |
