the restrictions on the cover page of this document.
As an additional capability, this CVR also monitors the status of an attached
Recorder Independent Power Supply, if present, and includes that status with the
OMS output reporting. The RIPS status is monitored using the CVR input pins listed
in Table 1.2:
Table 5. CVR Pins Assigned to RIPS Status Monitoring
Pin
Number
RIPS Monitoring Function State
10 CVR Stop Recording / RIPS Active Open = Not Active
Closed = RIPS Active or Stop Recording
29 RIPS Fault Open = RIPS Fault
Ground = RIPS OK
38 RIPS Maintenance Open = No RIPS Maintenance Needed
Ground = RIPS Maintenance Required
42 RIPS Present Pin Program Open = No RIPS Installed
Ground = RIPS Present
If the RIPS is not present, then the CVR will not monitor the RIPS status inputs, and
they will not be reported (default to “0’’ in Label 350 output).
