26Any given LDC collects data from a number of D-RORC cards connected to this same LDC by separate DDLs. This data is stored in corresponding number
27of DDL buffers.
28
29Each DDL buffer corresponds to a single D-RORC. The data this buffer contains are hardware generated by D-RORC. The buffer starts with common header
30which size and structure is standartized and mandatory for all detectors.
31The header contains among other words, so called Equipment ID word. This unique value for each D-RORC is calculated as detector ID << 8 + DDL index.
32For RICH the detector ID is 6 (reffered in the code as kRichRawId) while DDL indexes are from 0 to 13.
33
34Common header might be followed by the private one although RICH has no any private header, just uses the common one.
35
36Single RICH D-RORC serves one half of a chamber i.e. 3 photocathodes even LDC for left part( PCs 0-2-4) and odd LDC for right part(1-3-5)
37as it's seen from electronics side.
38
39So the LDC -chamber-ddl map is:
40DDL index 0 -> ch 1 left -> DDL ID 0x600 DDL index 1 -> ch 1 right -> DDL ID 0x601
41DDL index 2 -> ch 2 left -> DDL ID 0x602 DDL index 3 -> ch 2 right -> DDL ID 0x603
42DDL index 4 -> ch 3 left -> DDL ID 0x604 DDL index 5 -> ch 3 right -> DDL ID 0x605
43DDL index 6 -> ch 4 left -> DDL ID 0x606 DDL index 7 -> ch 4 right -> DDL ID 0x607
44DDL index 8 -> ch 5 left -> DDL ID 0x608 DDL index 9 -> ch 5 right -> DDL ID 0x609
45DDL index 10 -> ch 6 left -> DDL ID 0x60a DDL index 11 -> ch 6 right -> DDL ID 0x60b
46DDL index 12 -> ch 7 left -> DDL ID 0x60c DDL index 13 -> ch 7 right -> DDL ID 0x60d
47
48RICH FEE as seen by single D-RORC is composed from a number of DILOGIC chips organized in vertical stack of rows.
49Each DILOGIC chip serves 48 channels for the 8x6 pads (reffered in the code as kDilX,kDilY). Channels counted from 0 to 47.
50
51The mapping inside DILOGIC chip has the following structure (see from electronics side):
52
535 04 10 16 22 28 34 40 46
544 02 08 14 20 26 32 38 44
553 00 06 12 18 24 30 36 42
562 01 07 13 19 25 31 37 43
571 03 09 15 21 27 33 39 45
580 05 11 17 23 29 35 41 47
59
60 0 1 2 3 4 5 6 7 padx
61
6210 DILOGIC chips composes so called "row" in horizontal direction (reffered in the code as kNdil), so the row is 80x6 pads structure.
63DILOGIC chips in the row are counted from right to left as seen from electronics side, from 1 to 10.
6424 rows are piled up forming the whole FEE served by single D-RORC, so one DDL sees 80x144 pads separated in 3 photocathodes.
65Rows are counted from 1 to 24 from top to bottom for right half of the chamber (PCs 1-3-5) as seen from electronics side, meaning even LDC number
66 and from bottom to top for left half of the chamber (PCs 0-2-4) as seen from electronics side, meaning odd LDC number.
67
68RICH raw word is 32 bits with the structure:
69 00000 rrrrr dddd aaaaaa qqqqqqqqqqqq
70 5 bits zero 5 bits row number (1..24) 4 bits DILOGIC chip number (1..10) 6 bits DILOGIC address (0..47) 12 bits QDC value (0..4095)
