    Cable 2. B3 sband power supply building to B2A (dome). (top)

        This cable connects the sband power supply building with the fiber box B2a in the dome. There are 12 multimode fibers.

    Cable 3. B1 control room to B6 laser shack on platform corner. (top)

        Cable 3 goes from control room box b1 (2nd box) to laser shack B6. It currently stops at the weather station.
    It comes out at box B1 in the control room columns P,Q There are 12 multi mode fibers.

    Cable 4. B1 control room to laser shack. (top)

        The cable is not yet connectorized. It probably stops at the weather station. There are 5 single mode fibers.

    Cable 5. B1 control room to B7-12 tiedown 12. (top)

        The cable has 12 multi mode fibers. It goes from B12 (cols c,d) in the control room to B7-12 at tiedown 12. From 12 it goes to B7-4, then loops back to B7-12->B7-8. It mainly comes from patch cable 2 (pb2) that goes from B1 to the back of the pntcrate in the clock room.

    Cable 5a: Td 12 to Td 4

        This cable connects td 12 to td 4. It also loops back the cables from td4 that need to go to td8. These fibers go back to the fiber box at 12 and then on to td8.

    Cable 9. B1 rcvr room to B3 in sband power supply building. (top)

        This multi mode cable contains 12 fibers.

    Cable 10. B1 rcvr room to birdie generator bowl. (top)

        There are 6 single mode fibers that go from the control room to the birdie generator in the bowl.

    Platform ethernet (top)

        The platform ethernet originates in the rfi crate cpu rfip1. It goes via patch cable PA9,10 to RP1.port6. RP1.port5 goes upstairs to RP2 via C1.11,13.
        The ip net is 192.160.175.000 . The cpu names are:
  • pntp1 in rfi crate. platform0 is the host name for ifconfig on the ethernet port.
  • PA11 rx@rfip1 ->PA.9 ->RP1.tx6
  • PA12 tx@rfip1 -> PA.10->RP1.rx6

    • RP1: The repeater in the receiver room.

  • RP1.rx5 -> B1.C1.13 -> B2.13 -> RP2.tx11 repeater in dome
  • RP1.tx5 -> B1.C1.12 -> B2.12 -> RP2.rx11 repeater in dome
  • RP1.tx4 -> B1.C5.7  -> TD8.
  • RP1.rx4 -> B1.C5.8 -> TD8.
  • RP1.tx3 -> B1.C5.9 -> TD4.
  • RP1.rx3 -> B1.C5.10 -> TD4.
  • RP1.tx2 -> B1.C5.11 -> TD12
  • RP1.rx2 -> B1.C5.12 -> TD12

    • RP2: The repeater in the dome:

    Note: 12oct06: rp2 fails. we used a fiber barrel to jump port 11 input to port 12 input so the dewar monitoring would work. All the other ports won't work till we replace the repeater.

    Notes.. PC6  doesn't have enough fibers for the platform ethernet to go to tertiary and the turret fixed
    floor. We'll probably just run it to the tertiary. You can undo the jumper in B13 if you want it at the turret fixed floor.

    Patch cable 4 connects B2 in the dome to the rotary floor (moveable part).

    Scramnet fiber routing.

        The scramnet boards are a reflective memory system connected via fibers. It is a ring structure with a pair of cables entering and exiting each station (the order of the pair is
    not important). The connection topology (at least on the fiber labels) are:
    OPR->COR->DA->PNT->OBS->OPR

    Datataking ethernet

        The data ethernet for the vxworks datatking is a 10 Mbit ethernet coax (limited by the single board computer ethernet transceivers). The cabling order is:
