The L−3AR Portable Interface/2, provides a means to download the Data Link mes-
sage data at the CVR level so that an operator can easily and quickly download pre-
viously recorded Data Link information without removing the recorder from its mount-
ing.
The downloading may be performed by means of the ROC/7 with the L−3AR Audio
Data Link Player utility software. Refer to the L−3AR Audio Data Link Player (ADLP)
Operators manual, p/n: 165E3596−01 for more details.
H. CVR RIPS Status Monitoring
The Recorder Independent Power Supply (RIPS) is an ON−CONDITION LRU de-
signed to provide 10 minutes CVR backup power as per ARINC Characteristic
777−1. The CVR RIPS status monitoring provides a way to monitor the function sta-
tus of RIPS within the CVR. There is no change in CVR hardware except for the pin
assignments to the rear connector. Listed in Table 7 are the difference in the pin as-
signments of the CVR rear connector for both prior to RIPS and RIPS installation.
RIPS status will be received and transmitted using Fault Warning Label 350, Label
351 and Label 352 as part of the OMS. RIPS status will also be stored within the
CSMU memory and the data will be able to be retrieved using the existing support
equipment for analysis.

(1) RIPS Active
The CVR will use Pin 10 to receive the RIPS Active Status Discrete output. In
addition to reporting the RIPS Active status on this input, the assertion of this
input will start the CVR Stop Recording10 minute timer in order to retain this
standard CVR functionality. Since the RIPS is only active for up to 10 minutes
maximum, the function will be correct if either the RIPS or the CVR shuts down
first.
This status will be received and transmitted in the Label 350, Label 351, and
new Label 352 outputs as follows:
