Description and Operation
23–70–04
Additionally, the audio data can be down-loaded through the GSE connector, stored
on Type III PCMICA portable hard disks inserted in the PI Unit for later playback.
The Portable Interface Unit must have MOD-DOT 1 and the FA2100CVR must have
MOD-DOT 2 for Audio data downloading capability to be activated. For the PI/2 refer
to the PI/2 Operation Manual, P/N: 16521630−01on how audio data can be down-
loaded and the different ways to store data.
For operators using Rose 4.0 or higher software on a ROC or RAU, audio data along
with the flight data may be downloaded directly from a CVR and played back through
Rose. The audio and flight data will be time synchronized through the Rose soft-
ware. Refer to the Read−Out Support Equipment/Recorder Interface Software Ver-
sion 4.0 or Higher Operator’s Manual, Part Number 165E1696−03.
I. Data Reproduction
A standard cassette, reel-to-reel tape, or digital audio tape recorder can be used to
produce a high fidelity copy of the Model FA2100CVR recorded data. To do so, the
inputs of the copy recorder are connected to any one of the output RCA phono jacks
located on the Portable Interface (PI) Unit’s PI Audio Read-out Cable, p/n
17TES0051. Depending upon the type of recorder used for copying, the
FA2100CVR audio can be copied one channel at a time, or all individual channels
can be copied simultaneously. Reconstructed GMT/RSE output signals may also be
reproduced using the PI’s Aux Read-out Cable, p/n: 17TES0052.
J. Built-In-Test (BIT)
A continuous Built-In-Test (BIT) capability is provided at power up to establish and
monitor the mission fitness of the hardware. The built-in-test feature has been de-
signed to perform a continuous test of all bits within the solid-state memory located
in the Crash Survivable Memory Unit (CSMU).
An additional built-in-test is initiated by pressing a green TEST pushbutton located
on the front panel of the control unit (Models S151/S161, S152/S162 or
S251/S261). A green TEST indicator is located on the front panel of the Model
S151/S161/S152/S162 and S251/S261 Control Units to indicate successful comple-
tion of the manual test. (Note: The S161−1390−01 Control Unit does not have a LED
Test Indicator.) The TEST pushbutton is used to generate the 620- to 660-Hertz test
tone used for unit verification. This test tone is developed on the Audio Compressor
PWA and applied to each channel individually where it is processed, stored in
memory, read from memory, and checked for expected frequency and amplitude.
