B. Circuit Boards
The FA2100CVR electronics contain all the necessary power supplies and circuitry
to input, record, monitor and playback data. In addition, circuitry to perform self–
test functions and provide signals to the appropriate status indicators is also inte-
grated into the FA2100CVR electronics. The removable circuit boards include the
Aircraft Interface PWA, Audio Compressor PWA, and Acquisition Processor PWA.
C. Power, Control and Monitor Signal Interface Characteristics
Input power may be 115 Vac, 400 Hz or 28 Vdc (PN 2100−10X0−5X units are 28
Vdc only). At normal power level, an interruption equal to or less than 200 millisec-
onds will not affect the Model FA2100CVR's function. Upon application or re-ap-
plication, or normal, abnormal, or emergency power, the FA2100CVR will begin stor-
ing data in memory within 250 milliseconds.
