- 1 crate for the hodoscope that has 12 fADC (total 192 channels)
- Update firmware on all 3 VTPs to send fADC aggregated data frames in the EVIO format, through UDP.
- Design ERSAP FE application containing an actor that receives VTP frames through UDP, extracts information about the source/data ID and frame number (tick), and sends it to the EJFAT packetizing engine.
- Stage 1 testing: single stream/data-ID
