1. General Information
The part number of the unit, typically the 065-, 066- or 071- top level assembly part
number, contains a 206- item in its Bill of Materials. This 206- item is the configuration
control mechanism for programmable electronic devices of the unit. Two different
means exist to label the hardware/software configuration of the unit, depending upon
the part number of the unit.
a. When the part number of the unit is a 9-digit part as represented on the TSO
label, the last two digits of the 206- item are the digits of the sofware identification
(SW ID) tag that appears on the unit.
b. When the part number of the unit is a 12-digit part as represented on the TSO
label, the last four digits of the 206- item are the digits of the software modification
(SW MOD) tag that appears on the unit. In the example shown on sheet 1 of
Figure 6-1, the 206- item is flagged with an “A” in the right hand margin.
2. Definition of a Hardware/Software System
The 206- item represents the collection of all boards in the unit which contain
electronic programmable devices (software). The hardware/software system (206-)
bill of materials contains two categories of items.
a. The part number of the unit label (SOFT ID or SOFT MOD tag).
(1) In the case of the 9-digit TSOed unit, the unit label part number is
057-03284-00XX, where XX is the last two digits of the 206- number. The
software identification tag is illustrated below.
(2) In the case of the 12-digit TSOed unit, the unit label part number is
057-05287-YYYY, where YYYY is the last four digits of the 206- number. This
number is also referred to as the software mod level of the unit. The software
mod tag is illustrated below.
b. The 205- hardware/software board assemblies constitute all the
hardware/software boards which this unit contains. In the example, the item
marked “b” is the 205- hardware/software board used in the rest of the example.
