  1. Twisted Pair Cable Hybrid -Jumper Cable - Junction Card - Twisted Pair Cable – Adapter Card • Dense assembly (OD 5-7 mm) with • Twisted pairs : total 21; 44-pin 0.625 mm dual row Omnetics connector • differential signals • single-ended signals • Temperature, voltage sensing, spares • Common shield • Connectors can be purchased terminated with twisted pairs • Power and HV lines • Clock mini-coaxial cables • Round cross section – easy to route between Junction Cards and Adapter Cards

  2. 2.5 m 3-channel Junction Card 1. 2. 3. 90 mm x 25 mm • Two minicoax cables, MMX connectors • 6 AWG26 wires, Omnetics 0.050” 6-pin connector • 21 twisted pairs AWG34 in common shielding, Omnetics 0.025” 44-pin connector 4-channel Adapter Card

  3. 2.5 m 3-channel Junction Card 1. 2. 3. 90 mm x 25 mm • Two minicoax cables, MMX connectors • 6 AWG26 wires, Omnetics 0.050” 6-pin connector • Cable side : pin assembly (female) • AC side : socket assembly (male) • 21 twisted pairs AWG34 in common shielding, Omnetics 0.025” 44-pin connector • Cable side : pin assembly (female) • AC side : socket assembly (male) 4-channel Adapter Card

  4. Channel 1 • AWG26 HV field • AWG34 pair field • AWG26 LV field • Submini coax field • Common shielding field • Restrain field • (same for channels 2 and 3) 3. 5. 2. 1. 4. 6. Channel 2 Channel 3 90 mm x 25 mm

  5. HV on Adapter Card • For L2-5 HV is part of the LV/HV connector • For L0-1 • 1000 V spec • Two options • Bypass AC completely Mating connectors between HV cable and HV line of twisted pair cable Located not far from AC + no HV connector on AC - Twisted Pair Cable is different for L2-5 and L0-1 • One separate HV connector on AC Brings 3 separate HV (for 3-ch. Junction Card) to AC + same design of twisted pair cable - Additional connector on AC for L0-1

  6. Status • Signal twisted pair • AWG34 wire ordered from NE Electric Wire by CDF • will order 44-pin Omnetics connectors terminated with this wire • LV/HV 6-pin Omnetics connector • Nothing done, need to order • Submini coax cable – have enough for prototyping • Junction Card – should have prototypes in April • AVX connectors – should have soon • Assembly • Have quotes from Novosibirsk INP • Asking local vendors for quotes • First prototypes in June
