6.3.2.1.1 For 9-digit 205-WWWW-RN board labels, the first 7 digits are contained on a label part
number 057-050WW-00WW, and the last two digits are specified by 057-05252-00RN. The
revision number (RN) of the 205-WWWW-RN and the 057-05252-00RN part numbers are in-
cremented when the revision number of any 125-0XXXX-XXRN part number is incremented.
Therefore, the revision number of the 205-WWWW-RN and 057-05252-00RN part numbers
will be the same.
6.3.2.1.2 For 12-digit 205-0XXXX-XXRN board labels, the first 10 digits are contained on a label
part number 057-05252-XXXX, and the last two digits are specified by 057-05335-00RN. The
revision number (RN) of the 205-0XXXX-XXRN and the 057-05335-00RN part numbers are
incremented when the revision number of any 125-0XXXX-XXRN part number is incremented.
Therefore, the revision number of the 205-0XXXX-XXRN and 057-05335-00RN part numbers
will be the same. A circuit board identification tag is illustrated below.
6.3.2.2 The 125- software programmable device sets:
The 205- P/N SW/HW board set may contain one or more 125- P/N software programmable
device sets. A 125- P/N software programmable device set contains software and one or more
122- P/N programmed devices designated for that software function. When the revision num-
ber (RN) of any one of the 122-0XXXX-XXRN programmed devices is incremented in a new
software release, the revision number the 125-0XXXX-XXRN device set is also incremented.
This 125- P/N parts list also specifies the “U” or “I” circuit designators for the programmed de-
vices found on assembly drawings and schematic diagrams. Examples of 125- P/N sets are
shown in
figure 6-0 , sheet 1, items “C1,” and “C2” in the right hand margin.
6.3.2.3 The 126- P/N non-software programmable device sets:
When specified at the 205- P/N SW/HW board set level, the 126- P/N non-software program-
mable device set fulfills software requirements. The 126- P/N parts list contains one or more
122-0YYYY-YYRN P/N programmed devices. An example of a 126- P/N set that fulfills soft-
ware requirements is shown in
figure 6-0 , sheet 1, item “C3” in the right hand margin.
6.3.2.4 The 122- P/N programmed devices:
The 122-0XXXX-XXRN part number identifies discrete programmed devices found in both
software programmable 125- P/N device sets and non-software programmable 126- P/N de-
vice sets that perform a software function. These parts also appear on the 200- P/N or 300-
P/N hardware board parts list as 122-0XXXX-9999. Their true part number is found only on
the 125- P/N or 126- P/N parts list.
6.3.2.5 The 200- P/N or 300-P/N hardware board:
The 200- P/N or 300- P/N hardware circuit board is specified by the 205- SW/HW board set.
An example of a 200- P/N hardware board reference on a 205- SW/HW board set is shown in
figure 6-0 , sheet 1, last line.
6.3.3 HARDWARE BOARDS WITH PROGRAMMED DEVICES
The 200- P/N or 300- P/N hardware board parts list contains 126- P/N non-software program-
mable device sets that fulfill hardware requirements and reference to all 122- P/N programmed
devices on the hardware board.
6.3.3.1 The 126- P/N non-software programmable device sets:
205-06616- 0000
