IMPORTANT CAUTIONS
Installing ARINC 757A type CVR recorders connection wiring:
Damage will occur if power is applied on 2100−1027−02 recorder only if the interconnect wiring are not to
ARINC 757A requirements. This is because of the power pins are different in the ARINC 757A from the
ARINC 757. The mating keys on the connector are rotated different (Refer to Figure 5, sheet 2 of 2 of this
manual) as a safe guard to prevent mating a ARINC 757 type recorder. Do not remove or rotate the keys.

GENERAL
This product and related documentation must be reviewed for familiarization with
safety markings and instructions before operation.
This instrument was constructed in an ESD (electrostatic discharge) protected envi-
ronment. This is because most of the semiconductor devices used in this instrument
are susceptible to damage by static discharge.
Depending on the magnitude of the charge, device substrates can be punctured or
destroyed by contact or the mere proximity of a static charge. The results can cause
degradation of device performance, early failure, or immediate destruction.
These charges are generated in numerous ways such as simple contact, separation of
materials, and normal motions of persons working with static sensitive devices.
When handling or servicing equipment containing static sensitive devices, adequate
precautions must be taken to prevent device damage or destruction.
Only personnel who are thoroughly familiar with industry-accepted techniques for
handling static sensitive devices should attempt to service circuitry with these devices.
In all instances, measures must be taken to prevent static charge build-up on work
surfaces and persons handling the devices.
BEFORE APPLYING POWER
Verify that the product is set to match the line voltage and that the correct fuses
are installed.
Servicing instructions are for use by service-trained personnel only. To avoid dangerous
electric shock, do not perform any servicing unless qualified to do so.
Adjustments described in the manual are performed with power supplied to the
instrument while protective covers are removed. Energy available at many points may, if
contacted, result in personal injury.

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.

Model FA2100CVR Cockpit Voice Recorder
The FA2100CVR is available in two recording configurations: the first records a minimum of 30 minutes
of high quality audio, Part Number 2100–1010–( ), The second records a 120 minutes of high quality
audio and are Part Number 2100−1025/26/27−( ) and Part Number 2100–1020–( ) MOD−DOT #7.

Part Number 2100–1020–( ) pre MOD−DOT #7 records a fifth internal audio stream 30 mins of HQ au-
dio along with 120 mins of standard quality (SQ) audio. This fifth internal audio stream is a standard
quality recording of the combination of the Pilot, Co-Pilot, and Public Address or Third Crew Member
audio inputs. Part Number 2100−1020−( ) pre MOD−DOT #7 also records a sixth audio stream, a
standard quality recording of the Cockpit Area Microphone (CAM) audio input, for a minimum of 120
minutes. (Table 7 illustrates the recording specifications for the cockpit audio input and combined chan-
nels.) The audio inputs are conditioned, amplified, and equalized as necessary. The resulting signals are
converted to digital pulse code modulation (PCM) data. Part Numbers 2100−1025/26/27−( ) and
2100−1020−( ) MOD−DOT #7 only records a minimum of 120 minutes of high quality recording on all
four audio channels. Onboard Maintenance System (OMS) and Data Link are applicable to the
2100−1025−( ) and 2100−1026/27−02 configurations only. The Part Numbers 2100−1025−22/24 and
2100−1026/27−02 have the Onboard Maintenance System (OMS) and Data Link that includes RIPS
monitoring status.
The FA2100 FA2100CVR can record Greenwich Mean Time (GMT) Time via the ARINC 429 GMT in-
put and can record rotor speed data via the Rotor Speed input.
In ARINC 757 installations, the CVR Fault Line provides continuous status of FA2100CVR operation.
It may be connected to an annunciator or to an aircraft central maintenance computer.
At start−up, the FA2100CVR initiates a Built-in-Test (BIT) and then continuously monitors itself for
fault conditions.
Previously recorded information cannot be read from the Model FA2100CVR while it is installed in the
aircraft. (Refer to paragraph 6.0 for additional information).
1.5 Onboard Maintenance System Interface
The 2100−1025−( ), 2100−1026/27−02 CVR includes an ARINC 429, high speed, Onboard Maintenance
System (OMS) output interface (Pins 50/51) and an ARINC 429, low speed, OMS input interface (Pins
39/40). The 2100−1025/26/27−02 CVR supports a comprehensive OMS input/output protocol. Contact
L−3AR for further information.
The 2100−1025−22/24 supports the OMS interface as defined below. The OMS output interface is used
for transmission of CVR status information to a Centralized Maintenance Computer (CMC). The OMS
outputs are listed in Table 2.
Table 2. CVR OMS Output Words
Label Parameter Format Rate
350 CVR Status Word BNR 1 s
354 LRU identification (P/N and S/N) ISO 5 0.5 s
377 ARINC 429 equipment identification BCD 1 s
The Label 350 status word can be used to supplement or replace the discrete status outputs that are other-
wise available from the CVR (e.g. CVR Fault discrete, DataLink Fault Discrete, and Test Good Indicat-
or). The CVR software provides the Label 350 status output word, per ARINC 757, once per second.
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 3:

Ground = RIPS OK
38 RIPS Maintenance Open = No RIPS Maintenance Needed
Ground = RIPS Maintenance Required
42 RIPS Present Pin Program Open = No RIPS Installed

If the RIPS is not present, then the CVR will not monitor the RIPS status inputs, and they will not be re-
ported (default to “0’’ in Label 350 output).

In general, the Label 350 Status Word bits operate as outlined in ARINC 757−4, Attachment 20. There is
some interaction among the status bits in Label 350 with regard to Bit 11 (CVR Status), the CVR Fault
Status discrete output, and with the results of the CVR Push−to−Test function. These interactions are
summarized in Table 5 below:
The RIPS Status reporting is unique for the P/N: 2100−1025−24. RIPS Maintenance Status (Battery) is
indicated in bit 26 and RIPS Fault Status is indicated in bit 27. The CVR provides this data as received
from the RIPS in near real time over this OMS link. Upon power interruption or loss to the RIPS/CVR
system, the CVR would ensure that the RIPS supplies the CVR with the required backup power. Spe-
cifically, if the system was powered for at least 10 minutes but less than 15 minutes, a hold up time of at
least 5 minutes would be expected, and if powered for 15 minutes or more, a hold up time of at least 9
minutes would be expected.
If the RIPS meets this requirement, which ensures it is operating in accordance with its intended func-
tion, on the next power up the OMS discrete bits would indicate a no Maintenance and a no Fault condi-
tion regardless of the information the RIPS provides to the CVR. This no Maintenance and no Fault re-
porting would also occur if the previous recorder power cycle was less than 10 minutes in duration. In the
event the RIPS does not provide for its intended function on the previous power cycle, as described
above, the CVR would report actual real time status of the Maintenance and Fault signals it receives from
the RIPS in bits 20 and 15. Reporting of RIPS Present would always provide real time status on bit 22
and RIPS Active would always provide real time status on bit 21. To provide for comprehensive
troubleshooting, real time status of RIPS Maintenance and Fault will be provided on OMS label 350 bits
26 and 27 respectively.
In all scenarios, the status of the RIPS as reported to the recorder will be recorded in the Cockpit Voice
Recorder fault log.

It is important to note that certain CVR faults can only be detected through the “Push−to−Test” function.
This commanded BITE provides the only test of the CVR audio input circuits. During the Push−to−Test
operation, the CVR generates a test tone and sequentially injects it into each of the four audio input chan-
nels. A CVR fault will be asserted if the tone amplitude or frequency is not correctly detected. Like any
other internal CVR fault, this audio circuit failure will be reported using: the Label 350 output Bit 11, the
CVR Fault Status discrete output, and the Push−to−Test results. If an audio input circuit failure occurs
after a successful Push−to−Test operation, it will not be detected, or reported, until the next Push−to−Test
is initiated. This audio input circuit failure is the only fault that would not otherwise be detected and re-
ported by the CVR continuous BITE. Push−to−Test results are reported, during the test, using the CVR
Test Indicator output (Pins 15/16) which is usually connected to an indicator lamp or meter on the CVR
Control Unit. In addition, CVR failures reported through the Push−to−Test operation will be indicated by
muting of the CVR Monitor Audio output (Pins 5/6).
The fault criteria used to determine the reporting status associated with the CVR Label 350 Status Word
bits are summarized in Table 6.
