E. Assembly (A) Column
An ”A” in this column indicates that the part indicated is an assembly. If the P/N and
description reads ”200-0XXXX-0099 COMMON BOM” or ”200-XXXX-99 COMMON
BOM” the parts for that assembly are included in the same BOM. The parts breakdown
for an assembly with any other P/N will be found in the BOM with the same number.
F. Unit of Measure (UM) Column
This column indicates the Unit of Measure for each part. Common abbreviations found in
this column are listed below.
G. Quantity and Flavor Columns
Individual flavors of an assembly are identified by the last four digits of the P/N. Part
quantities for each flavor will be indicated under headings numbered 0000 through 9900
as required. The parts indicated in the 9900 Column are common to all other flavors of
the assembly and are considered the Common Bill of Material for the assembly.
H. Software Documentation
The documentation of software involves the use of several unique types of part numbers.
The following subsections list these part numbers with their descriptions. In some cases,
specific versions of hardware must be used with specific versions of software. To
determine the correct part number for ordering the programmed device, it is necessary to
know the part number of the device and the software revision level of the unit.
The last two digits of all software related part number, designated in the following text as
RN, indicate the revision number or level of the related software. This number is
incremented with each revision of software. For example, -01 is revision 0, -02 is revision
1, and so on. When ordering specific integrated circuits or devices, the applicable
122-XXXXX-XXRN part number is used. Applicable assembly drawings and schematic
diagrams will then follow in order.
