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

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

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.
