====== BTF tracker SFWR/HDWR setup ======
\\
The BTF tracker made by two FITPIX hosted in a movable holder over a [[https://www.newport.com/p/X48-1|Newport optical rail X48-1]], linked with an [[https://www.newport.com/p/M-CXL48-50|X48 Rail Carrier]].
Max adj. Longitudinal range = 800mm
Max adj. Vertical Range = 20mm

  * The BTF group controls these two FITPIX detector with an own software that fetches data from the FITPIX up to the maximum BTF beam rep rate (i.e. 50Hz, with internal trigger up to 80Hz).
\\
  * Data will be send to a [[https://memcached.org/|MeMCached]] server time tagged via NTP server
\\
  * Data structure
 
Info to be checked every time:

- Knowledge about MemCached(MC) and BTF timing
- Download and customization of the MC-data [[https://svn.lnf.infn.it/repos/btf_science/trunk/MC_btf/MC_read_tracker/|fetching protocol]] in users DAQ software
- how to setup users DAQ veto and trigger to FITPIXs


MC key to be fetched:\\
  * MC Key Master I05-W0256\\
  * MC Key Slave  F03-W0256\\


MemCached server: to be decided\\
Hopefully the same machine of the MAIN DAQ users PC (better timing)


FitPIX's MASTER have to be:
- triggered by users veto'ed DAQ 
- trigger has to be TTL complementary logic in HighZ
