A data link recorder as well as a voice recorder

• TSO-C177a Data Link Recorder Equipment carried alongside TSO-C123c
• No separate DLR needed to meet a data link recording requirement
• All valid ARINC-429 labels recorded to crash-survivable storage

Four channels, at the fidelity you choose

• Four audio inputs, configurable high or low fidelity
• Pilot and co-pilot boom headsets, intercom and cockpit area microphone
• Two rotor speed inputs and a Captain's Clock input on ARINC-429

Optional independent power

• RIPS maintains recorder, preamplifier and cockpit area microphone for 10 minutes after loss of aircraft power
• Super-capacitor bank, not a battery
• Yearly serviceability check, performed with an HHMPI or equivalent

Recording duration

• 2 hours of audio, minimum 2 hours of data link
• Operators requiring 25-hour cockpit voice recording should see SENTRY25, same enclosure, service bulletin upgrade path

Product numbers

• FDS84-2000 and FDS84-2001, SENTRY CVR
• FDS84-2100 and FDS84-2101, SENTRY CVR with RIPS
• FDS84-4200 Cockpit Control Unit for CVR-only installations
• FDS84-5001 Cockpit Area Microphone

FPGA architecture, SWaP optimized

• FPGA-based architecture with SWaP optimization, tailored for modern airframes
• Reduced footprint and low mass support direct replacement of legacy recorders without introducing new aircraft constraints
• Lower steady-state power draw preserves electrical margin for mission and cabin loads
• Contains no software, so recording is licence-free and no proprietary software is needed to retrieve the data
• Optional safety-critical soft-core processor available for third-party software

Specifications

• 3.3 in H x 4.9 in D x 6.0 in W (85 x 124 x 152 mm), base recorder
• 4.5 lb (2.04 kg), titanium enclosure
• 28 V DC, 4.5 W nominal
• Crash survivable to EUROCAE ED-112A
• Patent-pending memory protection system

Interfaces

• Ethernet 10/100 Base-T
• ARINC-717, 64 to 1,024 WPS
• ARINC-429, minimum two inputs
• RS-422/485
• Analog and discrete sensor inputs
• Two rotor speed inputs
• Four audio inputs, high or low fidelity

Certification

• TSO-C123c Cockpit Voice Recorder Equipment and TSO-C177a Data Link Recorder Equipment
• RIPS configurations add TSO-C155b
• Meets the requirements of EUROCAE ED-112A
• Qualified to DO-160G
• Installation approvals are published in the Flight Data Systems STC library

Installation note

• No flight data acquisition source required for CVR-only installations
• Beacon position and the optional RIPS module change the installed envelope. Regional beacon requirements apply, including Canada's mandate for non-lithium Underwater Locator Beacons
