NOTE:
Post-MOD DOT 13 CSMU Memory Assemblies have circuitry located
on the bottom (flat) side of the CSMU. Only place the CSMU down ori-

Acquisition Processor (AP) PWA Removal
(See Figure 306 or IPL Figure 1, Item 175)
The Model FA2100’s Acquisition Processor PWA (1-175) is mounted in the bottom
of the recorder chassis just below the CSMU. It provides an interface between the
Aircraft Interface PWA through Cable Assembly W001 connected at J2, the Audio
Compressor PWA through Cable Assembly W003 connected at J4, and the CSMU
via the Memory Interface Cable assembly connected at J1. The Acquisition PWA
also provides an interface between the FA2100 Recorder and Ground Support
Equipment, GSE, directly through front panel connector J3.
