6.2.6 ASSEMBLY (A) COLUMN
An “A” in this column indicates that the part is a sub-assembly. Each sub-assembly has a sep-
arate parts lists following the parent assembly. If the sub-assembly is a “COMMON BOM” with
a -9900, -0099, or -9999 suffix, the parts for that common assembly are included in the parent
assembly parts list as a separate column.
6.2.7 UNIT OF MEASURE (UM) COLUMN
This column indicates the unit of measure for each part. Common abbreviations found in this
column are listed in Table 6-3.
6.2.8 VERSION AND QUANTITY COLUMN
Individual versions of an assembly are identified by the last four digits of the P/N. The quantity
of parts for individual versions are listed in separate version columns -0000 through -9999.
The parts indicated in -0099, -9900, or -9999 version columns are common to all versions of
the assembly and constitute the “COMMON BOM.” Versions may also be called “flavors” in
parts lists. The terms are interchangeable.
6.3 SOFTWARE DOCUMENTATION
Unit software configuration is documented through several dedicated part number series. If a
unit contains software, the 206-XXXXX-XXXX P/N series designates the overall unit software/
hardware configuration set. The 205-XXXXX-XXXX P/N series designates the software/hard-
ware circuit board sets. The 126-XXXXX-XXXX P/N series designates non-software program-
mable device sets. The 125-XXXXX-XXXX P/N series designates software programmable de-
