  1. Cabling of RICH Electronics F. Bucci & M. Piccini

  2. Readout: Overview 1952 Photomultipliers splitted in two flanges  976 Photomultipliers per flange (Named Jura and Saleve) 64 Front-end boards (each one 4 NINO for 32 channels)  32 Front-end boards per flange (in 2 custom crates with 17 slots) 16 TDCB (data)+2 TDCB (OR of NINO chips, 256 signals) 4 TEL62 (data) +1 TEL62 (NINO OR) 2+1 TEL62 on Jura side and 2 TEL62 on Saleveside change!!! Low and High Voltage: 4 Agilent mainframes to power the front-end boards  2 on Jura and 2 Saleveside 4 SY1527 Caen Crate, all on Jura side, with 488 outputs (4 PMs each)

  4. Summary Known problems with the length of the cables to boot the CCPC  swith needed on Saleve side In total: 33 ethernet cables: 21 on Jura side 12 on Saleve side 12 (7?) CANBUS cables + 4? (to be defined): 8 (4?) on Jura side + 2? (to be defined) 4 (3?) on Saleve side + 2? (to be defined) 5 optical fibers: 3 on Jura side 2 on Saleve side External inputs needed for Choke&Error connections
