Voyage Data Recorder (SVDR)
Japan Radio Co., Ltd. (JRC)
Refurbished
The JRC JCY series consists of professional marine Voyage Data Recorder (VDR) and Simplified Voyage Data Recorder (S-VDR) systems developed by Japan Radio Co., Ltd. for continuous recording of essential shipboard navigation, communication, audio and sensor information.
The supplied SM MARINE SERVICE™ photograph shows a legacy JRC voyage-recording installation with a protective capsule and multi-channel microphone/audio recording equipment, representative of the type of architecture used in earlier JRC VDR generations.
The JCY family includes older systems such as JCY-1700, while the current JRC range includes the JCY-1900 VDR and JCY-1950 S-VDR. JRC describes JCY-1900 as a VDR and JCY-1950 as an S-VDR variant with either fixed or float-free capsule arrangement.
Manufacturer: Japan Radio Co., Ltd. (JRC)
Country of Origin: Japan
Models Covered: JCY-1700, JCY-1900, JCY-1950
Product Type: Voyage Data Recorder / Simplified Voyage Data Recorder
Marine Application: Continuous recording of navigational, audio, radar/ECDIS and ship-sensor data
System Category: Marine Safety / Navigation Recording Equipment
A Voyage Data Recorder is often described as the “black box” of a ship.
It continuously records critical information about vessel operation so that investigators and ship operators can reconstruct events after an accident or abnormal incident.
Typical recorded data can include:
• Date and time
• Vessel position
• Ship speed
• Heading
• Water depth
• Bridge alarms
• Steering commands and rudder response
• Engine commands and response
• Fire door and watertight door status
• AIS data
• Wind speed and direction
• Radar images
• ECDIS images
• Bridge audio
• VHF communication audio
JRC's current JCY-1900 specification lists these categories among the data recorded by the VDR system.
The JCY-1700 is one of JRC's earlier-generation Voyage Data Recorder systems.
JRC's own historical technical review identifies the JCY-1700 as a significant earlier VDR platform in the company's marine-electronics development history.
For vessels still operating JCY-1700 systems, typical replacement needs can include:
• Recording control equipment
• Protective capsule
• Microphone units
• Interface cards
• Data acquisition modules
• Power supply parts
• Recording media
• Cables and connectors
Because the JCY-1700 is a legacy generation, exact component compatibility should always be checked using the nameplate, part number and system configuration before supply.
The JRC JCY-1900 is a modern VDR platform designed to simplify installation, expand recording capability and integrate with current bridge-navigation systems.
JRC states that the JCY-1900 is built around its Multi Function Display architecture and can accept multiple radar and ECDIS video inputs over LAN.
The system also supports JRC's Remote Maintenance System, allowing shore-side diagnosis of onboard equipment when connected through suitable satellite communications.
The JCY-1950 is the S-VDR variant based on the JCY-1900 architecture.
JRC states that JCY-1950 can be configured with either a fixed protective capsule or a float-free capsule, subject to vessel class and flag-state requirements. It conforms to the revised S-VDR performance standard referenced by JRC as MSC.493(104).
This makes it particularly suitable for replacing older S-VDR installations that may no longer receive manufacturer support.
JRC officially lists the following major equipment:
NDV-1900 – Recording Control Unit for JCY-1900
NDV-1950 – Recording Control Unit for JCY-1950
NCG-1900 – Operation Panel Unit for JCY-1900
NCG-1950 – Operation Panel Unit for JCY-1950
NDH-338 – Fixed Protective Capsule
NDH-339B – Float-Free Capsule
NVT-181 – Microphone Unit
NQE-7700A – Junction Box
CYC-825 – Playback Software for Accident Investigators
CYC-826 – Playback Software for Users
Optional equipment includes:
NVT-182 – Waterproof Microphone Unit
NCT-82 – 32-channel Contact Signal Input Unit
NCT-83 – 64-channel Contact Signal Input Unit
NCT-84 – Data Acquisition Unit
CEF-60 – A/D Converter Board
NWP-69 – Image Capture Unit
JRC's current JCY-1900 specification lists:
Fixed Capsule: 48 hours, 32 GB
Float-Free Capsule: 48 hours, 80 GB
Internal Silicon Disk: 720 hours / 30 days, 512 GB
This extended internal storage allows operators to review a much longer period of voyage information than the crash-protected capsule alone.
A JCY-1900/1950 system can record:
• Date and time
• GPS position
• Speed
• Heading
• Depth
• Bridge alerts
• Steering orders and response
• Engine orders and response
• Door/opening status
• Acceleration and hull stress
• Wind speed and direction
• AIS
• Electronic inclinometer
• Electronic logbook
• BNWAS
• Speed-through-ground and speed-through-water inputs
• Bridge audio
• VHF communication audio
• X-band radar
• S-band radar
• ECDIS
These categories are explicitly listed in JRC's JCY-1900 technical information.
Recorded VDR information is only useful if it can be recovered and played back correctly.
JRC provides:
CYC-825 – Accident-investigator playback software
CYC-826 – User playback software
JRC's Smart Ship Viewer platform can also retrieve JCY-1900/1950 VDR information via J-Marine Cloud on suitably connected ships. The available recordings include navigation sensor data, radar/ECDIS images and bridge/VHF audio.
JRC's Remote Maintenance System can use JCY-1900 / JCY-1800 VDR equipment as an onboard server for remote technical diagnosis over secure satellite communications.
This allows authorized service staff to inspect equipment status while the vessel remains at sea and prepare necessary repairs before the ship reaches port.
JRC VDR and S-VDR systems are used aboard:
• Cargo Ships
• Container Ships
• Bulk Carriers
• Oil Tankers
• Chemical Tankers
• LNG/LPG Carriers
• Passenger Vessels
• Offshore Vessels
• Merchant Ships
• Other SOLAS-regulated vessels
Check:
• Incoming power
• Power supply components
• Circuit protection
• Recording Control Unit
• Internal cables and connectors
For JCY-1900/1950 systems, inspect the NCG operation panel, connection to the NDV recording unit and power supplied from the recording-control unit.
Inspect capsule cable, interface board, junction box and capsule status.
A capsule error should not automatically be assumed to mean the protective capsule itself has failed.
Check:
• NVT microphone unit
• Microphone cable
• Audio interface
• Recording channel configuration
• Connector condition
Inspect radar video/LAN input, image capture arrangement and VDR configuration.
Check network/video input, ECDIS output and VDR recording configuration.
Verify the external source first, then inspect VDR interface wiring and data acquisition modules.
Storage-related faults can affect recording continuity. Internal SSD/silicon disk and recording media should be checked with the appropriate diagnostic tools.
Verify the correct playback software, recording format and exported data set before assuming recording hardware failure.
Typical service conditions may include:
• Recording failure
• Capsule communication fault
• Audio channel fault
• Sensor input missing
• Radar/ECDIS image input failure
• Storage media fault
• Power-supply problem
• Network communication problem
• Operation panel communication fault
Exact alarm text and codes depend on the model/software version and should be checked against the applicable JRC manual rather than guessed.
• Check all microphone channels regularly.
• Verify radar and ECDIS image recording.
• Confirm GPS, gyro, AIS and speed-log data inputs.
• Inspect capsule connection and status.
• Check battery / backup power condition where applicable.
• Verify free storage capacity and media health.
• Test playback periodically.
• Inspect junction boxes and interface boards.
• Keep equipment ventilation clear.
• Carry out the required VDR Annual Performance Test through approved service channels.

JRC VDR systems are widely integrated with bridge equipment, including radar, ECDIS, AIS, GPS, gyrocompass, speed log, echo sounder and alarm systems.
Replacing only a failed microphone, capsule, recording unit, operation panel or interface module can often avoid a much larger bridge rewiring project.
The newer JCY-1900/1950 platform also supports JRC's cloud/remote-maintenance ecosystem, including VDR data retrieval through Smart Ship Viewer.
The JCY-1700 is an older-generation JRC Voyage Data Recorder used to record vessel navigation, audio and operational information.
The JCY-1900 is JRC's modern Voyage Data Recorder platform with extended recording, LAN video inputs and remote-maintenance capabilities.
The JCY-1950 is the S-VDR version based on the JCY-1900 architecture and can use either fixed or float-free protective capsule arrangements.
