new documents to clarify the mapping between bpms, fecs and fip addresses. (edms 1342851 )

• Document : “LHC Orbit System Low level SW procedures” : EDMS ID 1348775. Contains an introduction to the system infrastructure and several low level procedures:

• Calculation of the LHC Beam Position in mm: Main difference wrt LHC run#1 are:

• Update of the coefficients.• 2D geometrical corrections. Those coefficients can be found in Andriy’s

document : EDMS ID 1342295 (Table 2).• No more multiplication by Kf before geom. non-linearity correction.• Tilt expressed as an angle, and not as a cos (45°), to allow generalization to all

the BPMs. • QA: SW “embedded” offsets and tilts should be specified on this

document.• D. Missiaen will provide us updated info about offsets & tilts by the end

of the year. (BPMD, etc).• Temperature compensation: keep as it is implemented now. • Hard-coded

• Some errors were found in the FIP decoding for the “FipOverview” procedure described in the previous document version. Application should be checked.

• Described procedure to obtain serial numbers of the tunnel cards as human readable numbers.

• New documents to clarify the mapping between BPMs, FECs and FIP addresses. (EDMS 1342851).

• There will be new BPMs, and some name changes. These changes will be propagated soon to the previous document.

• Pt 3 :

• Pt 4 : New monitors for the BGI: BPMWI.5L4.B1 and BPMWI.5R4.B2• Pt6:

• Pt 5 : BPMs in Roman Pots will move from 4L6 to 6L5 and from 4R5 to 6R5. 6L5 and 6R5 already had Totem stations. New names to be defined.

• Channels equipped with Diode Orbit also seen by the OFC: • Duplicated channels for BPMS in Q1.• Collimator BPMs.

• Terminals in the SR buildings?

Before LS1, PC in rack BY01.

1) Either we find a new place to install them back• There are empty racks in the same row: SR1, SR2, SR5, SR6.• SX4 we can place it in a table in the BI closed local.• SR8: empty racks • Without place: SR3, SR7 and SR8.

2) Either we replace them by CO centrally managed PC + 1U KVM console installed in a free slot at rack BY05.

• CO accepts this solution and seems easy to integrate.• Prices from 700CHF up to 2k CHF, and typically ~1400CHF.

Some KVM consoles:

• StartTech.com : starting at ~760 USD (17” 1280x1024 display, 1 VGA and 1 USB A) up to 1400 USD (17” 1920x1080 display, 1 USB B, 1 VGA and 2 PS/2).

• Dell: ref. 331-9437 for 1240 USD (18.5" display, and 1 KVM and 2xUSB interfaces).• APC: 17” or 19”, comes with a custom cable at the console end and it has 2 PS/2 + 1

VGA at the other end.• Tripp lite: 17” 1280x1024 LCD with also a KVM cable kit (VGA + 2 PS/2). 2kCHF at

mouser.ch• Schroff: 17” 1280x1024, 2 PS/2 or USB, about 1200 euro/piece.

Drawing is wrong !

No rack empty but these two have many space available.
