Model FA2100CVR
1.4.1 Recorder Unit
The FA2100CVRs are housed in ARINC 404A, 1/2-ATR short cases (refer to Figure 1). The chassis and
Crash Survivable Memory Unit (CSMU) are painted international orange. Two reflective stripes are loc-
ated on the CSMU.
The FA2100CVR consists of a chassis and front panel, three Printed Wiring Assemblies (Aircraft Inter-
face PWA, Audio Compressor PWA, and Acquisition Processor PWA), and the Crash Survivable
Memory Unit (CSMU). The CSMU contains the solid state flash memory used as the recording medium.
An Underwater Locator Device (ULD), also referred to as an underwater acoustic beacon, is mounted ho-
rizontally on the front of the CSMU and is also used as a the recorder's carrying handle. The ULD is
equipped with a battery that has an expected life of more then six years. The ULD meets or exceeds the
requirements of FAA TSO–C121. The Ground Support Equipment (GSE) connector is located on the
front of the FA2100CVR. This connector provides the interface from the recorder to GSE for checkout
of the recorder, or to transfer data to a readout device. The FA2100CVR is connected to aircraft wiring
via a 57-pin, DPXB-style connector.
