Recorder Synchronization
The FA2100CVR equipment is designed to be able to record time code from an
ARINC 429 in priority and later FSK source (the frequencies used are /
−
30Hz and /
−
30Hz), depending on the source used on the aircraft. For
Models FA2100CVR, p/n: 2100
−
1X20
−
02/2100
−
1X25
−
( ), 2100
−
1X26
−
( ), and
2100
−
1X27
−
( ) the recorder automatically detects which source is received, ac-
quires the time data, and stores it into memory.
The A429 clock refresh time is to one (1) second; if after this time, the CVR is capa-
ble of acquiring and to recording the FSK Frequency necessary for synchronization.
The ARINC GMT word (either label 125 UTC BCD or 150 UTC BNR) is transmitted
at a rate of one (1) second, the FA2100CVR recorder is designed to recognize and
record GMT word sent at this transmit rate.
The CVR is capable of recording both label 150 or 125 with a priority for Label 150 if
both labels are present.
The CVR equipment contains an internal time reference in the event FSK or ARINC
429 time reference is not available.
Label 350, Bit 17 indicates the status of the clock as the following: 0=ok and 1=fail-
ure.

Data downloading (P/N: 2100

( ) only)
It is possible to download the Data Link message data from the crash protected me-
dium, while the recorder is installed on the aircraft (as per ED112 Part IV § IV
−
2.2.3).
The L
−
3AR Portable Interface, 17TES0043 PI/1; 17TES0062 PI/2, provides a
means to download the Data Link message data at the CVR on-aircraft so that an
operator can easily and quickly download previously recorded Data Link information
without removing the recorder from its mounting.
The downloading may be performed by means a ground PC personal computer on
and in laboratory with the L
−
3AR Audio Data Link Playback software, ADLP soft-
ware. Refer to the L

01 for more details.
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 software. Refer to the Read
