G. Storage Capacity
The Model FA2100CVR storage media is designated as the Crash Survivable Me-
mory Unit (CSMU). The CSMU in the Model FA2100, p/n 2100–1010–( ), contains
flash memory with enough storage capacity to allow continuous recording of the four
high quality audio channels for a minimum of 30 minutes. The CSMU Flash memory
in the Model FA2100, p/n 2100–1020–( ) pre MOD−DOT #7, provides enough stor-
age capacity to allow continuous recording of the four high quality audio channels for
a minimum of 30 minutes, and the standard quality combined and cockpit micro-
phone channels for a minimum of 120 minutes. The CSMU Flash memory in the
Model FA2100, p/n 2100–1025/10261027–( ) and p/n 2100−1020−( ) post MOD−
DOT #7, provides enough storage capacity to allow continuous recording of the four
high quality audio channels for a minimum of 120 minutes.
H. Data Retrieval
Incorporated into the FA2100CVR aircraft installation is a “Record On” jumper. Dur-
ing bench test of the FA2100CVR, removal of the jumper disables the record func-
tion of the recorder, thereby allowing playback of the recorded data. While in the
Playback mode, replaying of recorded data is controlled by the Portable Interface
(PI) Unit p/n: 17TES0043 or Portable Interface/2 (PI/2) Unit P/N: 17TES0062. De-
tailed operation of the PI is contained in the PI Operation Manual, P/N:
165E1630−00 or PI/2 Operation Manual, P/N: 16521630−01.
To retrieve data from the recorder, the recorder must be removed from the aircraft,
connected to appropriate AC or DC power (DC power only for FA2100CVR Models
2100−1010−5X and 2100−1020−5X), and the Portable Interface Unit (PI) p/n:
17TES0043 or Portable Interface/2 (PI/2) Unit P/N: 17TES0062 must be connected
to the recorder’s front panel GSE connector.
The PI or PI/2 Unit allows a user to replay, using a 600-ohm headset and a
600−ohm boomset microphone headset in the case of the 2100−1025/1026/1027−(
) model, any one of the high quality audio channels, or the cockpit area microphone
channel. The PI or PI/2 Unit also has the capability to search through the stored
data using the fast forward and fast reverse command keys. The fidelity of the
FA2100CVR audio data output at the PI or PI/2 Unit is such that its internal speaker
allows quality analysis of the recorded data. The PI or PI/2 Unit also simplifies con-
nection to standard commercial recording equipment for duplicating any of the moni-
tored audio streams.
