RIPS Fault
The CVR will use Pin 29 to receive the RIPS Failure Status Discrete output.
This discrete input is presently assigned in ARINC 757A as FDR Rate A for
combination recorder applications. This discrete input is not presently utilized
by the pre RIPS CVR software. This RIPS status will be received and transmit-
ted in the Label 350, Label 351, and new Label 352 outputs as follows:

RIPS Maintenance
The CVR will use Pin 38 to receive the RIPS Maintenance Status Discrete out-
put. This discrete input is presently assigned in ARINC 757A as FDR Rate B
for combination recorder applications. This discrete input is not presently util-
ized by the pre RIPS CVR software. This RIPS status will be received and
transmitted in the Label 350, Label 351, and new Label 352 outputs as follows:

RIPS Present
Use of CVR Pin 42, ”CVR Ident” is being used for the RIPS Present Pin Pro-
gram. Since we do not anticipate more than one CVR installed on any current
aircraft type, the CVR Ident will be defaulted to the first CVR installed (0) in the
software for BITE reporting purposes instead of reading this through Pin 42.
This will free Pin 42 for use as the RIPS Present Pin Program. The status of
this discrete input will be used to modulate the Label 350, Label 351, and Label
352 reporting of RIPS status. If RIPS is not present, then all of the associated
RIPS status bits (Fault, Maintenance, Active, and Present) will be set to zero
(0) in the Label 350/352 output. Likewise, RIPS Fault and RIPS Maintenance
will default to zero (0) in the Label 351 output if the RIPS is not present.
If the RIPS is not present, then any reference to RIPS in the Interactive OMS
output pages will be suppressed. However, in the case where the CVR is re-
