====Setup====
Turn on crate\\
Login to cmspixel PC\\

====Trigger====
Start XDAQ TTC control:\\
  source TriDAS/pixel/POSRelease/setenv.sh
  cd run/TTC/
  source run_ttcci.csh

Open firefox ("TTCci XDAQ" bookmark)\\
In the TTCciControl tab:
  click: configure
  click: enable
  
//**''Note: PC name, port, TTCci slot and TTC configuration file are sepcified in run/TTC/XDAQConfig.xml''**//

====pxlpilotfed====
In a new terminal:\\
  source TriDAS/pixel/POSRelease/setenv.sh
  cd TriDAS/pixel/pxlpilotfed
  ./pxlpilotfed

The program gives a list of options which can be selected by keyboard entries.

//**''Note: TTCci/FED base addressed defined in __ttcaddcsr0/FEDBASE__''**//


====case 'a'====
Inject one trigger and readout FED.\\

The above is the output of one fiber. The fiber is selcted by a VME command:
  //this choose the channel read by piggy: ex. CHa_CHb_mux+0x2304 reads channel 4
  VMEout(0x3,LAD_N+0x1a8000,4,CHa_CHb_mux+0x2300); // ch selection for transparent mode: 5-fiber#12, 4-fiber#11, 3-fiber#10, 2-fiber#9, 1-fiber# 8, 0-fiber#7
  VMEout(0x3,LAD_S+0x1a8000,4,CHa_CHb_mux+0x2304); // ch selection for transparent mode: 5-fiber#12, 4-fiber#11, 3-fiber#10, 2-fiber#9, 1-fiber# 8, 0-fiber#7
  
The output can be decoded using Satoshi's script (see: https://github.com/hsatoshi/FpixTbmDecoder):\\

**Output of FIFO 1**: Data for all channels which are connected is printed (loop over all channels).\\
Decodes TBM Header and Trailers. \\
Channel mapping for FIFO1 is described on p.1 here: http://www.physik.uzh.ch/~leac/CMSPixel/Docs/FED/FED_configuration_map.pdf\\
Channels 1-4 are Nup, channels 5-9 are Ndown\\
Channel selection described on p.3.
