SECTION I. DOWNLOADING CMB INFORMATION

1.1.

DOWNLOADING CMB INFORMATION.

Description: This task covers downloading stored maintenance information from the CMB.

1.2.

General Information: A contact memory button (CMB) is a battery-free, read/write electronic data

storage device attached to selected components tracked by the DA Form 2410. The CMB

enhances configuration management, asset tracking, inspection and maintenance for the life of

the component to which it is attached.

Aviation Maintenance Automated Tracking System (AMATS) is an automated system that uses

CMBs to input part data into an existing maintenance management information system (MMIS).

Data stored on the CMB is retrieved either by the handheld PC using the Mini Fingertip Probe

attachment or by a laptop using a ButtonLink (Figure 1). Information is viewable and updateable

on site. The retrieved information is then inputted into the MMIS. Together, CMBs and an MMIS

create an automated maintenance environment. After maintenance is performed on an aircraft

component and the maintenance data is entered into the MMIS, the handheld PC or laptop is

used to read all of the component's new historical data and to then download the data to a new or

reusable CMB.

Initial Setup

Tools:

Handheld PC (Item 2, Figure 1)

Handheld PC Charging Cradle (Item 1, Figure 1)

ButtonLink, Serial (Item 3, Figure 1)

ButtonLink, USB (Item 4, Figure 1)

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.
