POPULATING A CMB
4.1.
Description: This task covers the process of populating a CMB.
4.2.
General Information: A CMB is populated with historical maintenance information for the component
to which it is attached. A CMB attached to an assembly with DA Form 2410 tracked subcomponents
will usually contain all subcomponent historical maintenance information as well. The CMB is
populated after all maintenance and testing on the component is finished and all maintenance records
have been updated in the facility's existing maintenance information database. The same tools used
to read and download the CMB (refer to Section I) are used to populate the CMB. CMB population is
critical prior to shipping a component, so the location later receiving the component can take
advantage of the accurate, up-to-date electronic data on the CMB rather than being forced to enter
data by hand using the attached paperwork.
4.3.
Initial Setup
Tools:
Handheld PC (Item 2, Figure 1)
ButtonLink, USB (Item 4, Figure 1)
Handheld PC Charging Cradle (Item 1, Figure 1)
Mini Fingertip Probe (Item 5, Figure 1)
ButtonLink, Serial (Item 3, Figure 1)
Laptop (Item 7, Figure 1) or other computer
CAUTION
Handheld PCs contain rechargeable battery packs. These units must be
pre-charged in accordance with the device's operating instructions.
Handle the AMATS equipment with care, as the electronic circuitry can be
damaged from improper handling. Use surge protectors whenever possible.
NOTE
When populating a CMB, make sure the probe is vertical to the CMB, and press
down firmly. Hold the probe in this position, until the writing device shows that
the population of the CMB is complete.
4.4.
Populating the CMB
4.4.1
Notify database management personnel: Notify the applicable database management personnel that
the CMB is ready to receive maintenance information from the facility's maintenance information
database.
4.4.2
Upload component maintenance information: Upload the component's maintenance information to
either the AMATS computer or the handheld PC from the facility's existing maintenance information
database
4.4.3
Populate the CMB: Populate the CMB from either the AMATS computer using the ButtonLink or from
the handheld PC using the mini fingertip probe (See Figure 1).
