Description

Bif is a modified mini-tlu (https://www.ohwr.org/projects/fmc-mtlu/wiki) with a custom firmware (https://svnsrv.desy.de/k5websvn/wsvn/General.ScCalo_DAQ/bif/)

It provides 4 trigger inputs, but capability to store them all at once is limited. They all have to come within the same 25ns period.

  • Inputs are internally terminated (50 Ohm)
  • Logic level: Nim

Requires a gigabit ethernet! May fail to communicate over 100 MBit ethernet

The IP address is 192.168.200.16

Connection via "Frankenstein" cable

  • Frankenstein RJ45 goes to the RJ45 connector on the mezzanine
  • ground lemo cable needs to be attached to one of the inputs. The central signal pin is removed from this connector, therefore it can be used together with lemo-T splitter
  • Preferred trigger input is trigger 3.
  • clock pin need to be carefully inserted (see the right detail), red wire goes to the upper pin
  • No labels
