====== Installation and commissioning of cable chamber ======

===== Geometry =====

Four FEBs intsalled from external to middle:
   * TDC 5, First serie, strip 1-12
   * TDC 8, Second serie, strip 13-24,
   * TDC 6, second serie, strip 25-36
   * TDC 7, second serie, strip 37-48

Each of it is reading 12 strips both side. The mapping of the 12 strips is the following:
^Strip ^ TDC channel High Radius ^ TDC channel Low Radius ^
|1| 10 |14| 
|2| 6 |11|
|3| 2 |7|
|4| 0 |3| 
|5| 4 |1| 
|6| 8 |5| 
|7| 12 |9| 
|8| 16 |13| 
|9| 18 |15| 
|10| 20 |17| 
|11| 22 |19| 
|12| missing (23) |21| 

The channel 23 is not connected to a lemo in the current version of firmware. Upgrade version of firmware with the correct connection will require a new calibration of Petirocs DAC

Run 739605,606 and 607 were done to align all pedestal to VThTime @ 480


The settings for starting a run are:
<code>
# 4 FEBS aligned 491+15
daqcontrol --daq-download --dbstate=FE1_24CH_29
daqcontrol --daq-setvth --vth=506
daqcontrol --daq-configure
daqcontrol --trig-spillof --clock=10000
daqcontrol --trig-spillon --clock=100000
# 499 for TDC5 and 494 for TDC8 in DB
#daqcontrol --daq-setvth --vth=500
daqcontrol --trig-spillreg --value=4
