COMPONENT MAINTENANCE MANUAL
FA2100CVR
ROSE 4.0 or higher on a ROC or RAU is recommended to download
directly from a CVR and convert audio into a .WAV for playback. Re-
fer to the Read-Out Support Equipment / Recorder Interface Software
version 4.0 or Higher Operator's Manual, p/n 165E1696-03, to Re-
trieve Flight Data and / or Audio Data from a Recorder.
When decompressing Standard Quality Audio from a 2−Hr.
FA2100CVR, p/n: 2100−1020−XX, pre Hardware MOD−DOT #7, you
must have the RIU powered and the Altera chip reset using the Power
−> RIU Interface Reset command.
This is required because hardware inside the RIU is used for con-
verting of the 2−bit compressed Standard Quality Combined (SQV)
and Standard Quality CAM (SQC) channels.
This is not a requirement for the High Quality Channels (HQV & HQC)
because this 3−bit compression is converted using the CATS soft-
ware. The FA2100CVRs that have Hardware MOD−DOT #7 installed
have full two hour High−Quality for all four audio channels as does
all 30−Minute FA2100CVRs.
