+====== Catania 09 TB ======
+Going to acquire:
+  - Start counter (1 or 2): Scintillator
+  - Tracker: DCH
+  - Dump: Scintillator
+=== STC ===
+Readout (splitted channels):
+  * 2 channels that go to Discriminator to NIM - ECL converter to Fast TDC.
+  * 2 channels go to WVF
+=== Dump ===
+Readout (splitted channels):
+  * 2 channels that go to Discriminator to NIM - ECL converter to Fast TDC.
+  * 2 channels go to WVF
+=== DCH ===
+Readout :
+  * 16 channels that go to discriminator to NIM - ECL converter to Fast TDC.
+===== Hardware =====
+==== Power Supply ====
+  - Low voltage Power supply for DCH readout [OK]
+  - Low voltage Power supply for STC [OK]
+==== Gas ====
+  - Gas mixture: Ar, CO2, Iso [available @ CT]
+  - Gas pipes + connections [available @ CT]
+  - Mixer + fluximeter : to be brought
+==== Cables ====
+HV cables
+  - 2 cables are needed for DCH [@ CT]
+  - 2(3) cables are needed for Dump or CsI [@ CT]
+LV cables
+  - LV is needed by Photomultipliers of STC
+Chmb Acquisition
+  - Need 16 Long Lemo from CHMb to Discriminator
+  - Need 16 short Lemo from Discriminator to Nim - Ecl converter
+  - Need 16 flat cables from converter to TDC
+STC + Dump Acquisition
+  - Need 6 Long Lemo from detector to Splitter
+  - Need 6 Short Lemo from Splitter to Discriminator
+  - Need 6 Short Lemo from Splitter to WVD
+  - Need 6 Short Lemo from Discriminator to Trigger Logic
+Trigger Logic
+  - Need Short Lemo cables from Discriminator to Coincidence unit
+==== HV ====
+  - Two HV modules needed (one for STC + Dump and one for DCH)
+==== LV ====
+  - One module plus cables is needed [brought it]
+==== Trigger ====
+  - 1 PLU [need 1 as spare] for 4 input from scintillators
+    - Exit goes to
+        * TDC trigger
+        * WFD trigger
+        * I/O reg trigger
+  - Dual timer: needed to implement busy
+==== DAQ ====
+  - Splitter [Splitting cables?? will save module]
+     * Needed to split the output of Scintillators to TDC, WVD
+     * Available only 4 Channels: Ok for 1 STC + Dump. **Problem if STC>1 or DCH splitted**
+  - Discriminator
+     * Need to discriminate 16 (max) DCH +  4 Dump + STC
+     * Currently available only 8 chs : **2*8 chs missing**
+  - Coincidence Unit
+  - I/O Register
+  - Converter
+     * 2 modules available: 1*16 + 1*8 = 24 chs total [OK]
+  - Fast TDC
+     * 64 Channels available [OK]
+  - WaveForm digitizer
+     * 8 Chs available with sampling @ 500 MHz [OK?]
+===== Software =====
+==== ACQ Code ====
+=== Acquisition ===
+The acquisition code is compiled on the CPU.
+Performs the reading of the various modules (returning each a vector with the needed information)
+and also the event writing. Writing is implemented as unformatted/binary.
+  - Hardware: CPU
+  - Code location: /home/daq/CT
+  - Running instructions:
+    - compile with make acquire
+    - run with ./acquire + options.
+Provided options are:
+  - [-n] : number of events to be acquired
+  - [-p] : number of events on which the ACQ rate is computed
+  - [-f] : Full path to output file (binary, unformatted)
+  - [-z] : switch on and off of zero suppression
+=== Monitoring ===
+  - Hardware: PC daq
+  - Code location: /home/daq/acq
+  - Running instructions:
+    - compile with make Analizer
+    - run with ./Analizer + options
+Provided options are:
+  - [-in] : full path top input file (link to data/ dire of acquisition is provided)
+  - [-out] : output root file
+==== Event structure ====
+  - Evt num
+  - Num boards
+  - Then for each of the boards in the event: b{j}_nwords [j=0,N_boards]
+  - Then for each of the boards in the event: b{j}_words{i} [j=0,N_boards][i=0,b{j}_nwords]
+Boards order:
+  - IOREG
+  - TDC1190
+  - WVD
+=== Structure of Board events ===
+== IOREG ==
+To be implemented
+== TDC1190 ==
+  - 1w ->Evnum
+  - 3w*n_firing_cha ->For each firing channel 3 words containing event number channel and measurement are stored
+  - 1w ->Trailer (possible check of errors)
+== WVD ==
+To test the zero suppression you need to test the 3rd word  of the event, checking the 24th bit (if == 1 -> zs data):  data>>24 & 0x1;
+  - if zero suppression
+    - 1w -> n of words in the event
+    - 1w -> falg for checking ZS data
+    - 1w -> mask of enabled channels
+    - 1w -> Trigger time
+    - Then For each channel
+      - 1w -> Total channel words [included this one]
+      - 1w -> Number of 32 bit words skipped
+        - nsam*1w -> Number of words with samples over threshold
+        - 1w -> Number of 32 bits skipped
+  - else
+    - 1w -> n of words in the event
+    - 1w -> falg for checking ZS data
+    - 1w -> mask of enabled channels
+    - 1w -> Trigger time
+    - 512w*ncha -> 512 words for each enabled channel
+==== To Do List ====
+  - Test TDC
+  - Calibrations
+    * 32 chs TDC
+    * 8 chs
