1.1. Outline of the Equipment

This equipment helps investigators identify the causes of marine accidents in order to prevent their recurrence.
The equipment records navigation and hull data, as required by International Standards.

1.2. Feature of New VDR/S-VDR

1) Sensor Data I/F
● Reduction of serial wiring cables is possible by sharing data (LAN: IEC61162-450) with new RA-
DAR/ECDIS.
(For introduction, confirmation for supervisory authorities and ship's classification is required.)
2) Image Data I/F
● Reduction of RGB wiring cable (5 coaxial cables) is possible by connecting to new RADAR/ECDIS
through LAN (IEC61162-450).
3) Capsule I/F
● No separate power cable is required since power is supplied to the capsule unit with the LAN cable.
4) Data recording in capsule units (meet the demands of new standard)
Both the fixed protective capsule unit and the float-free capsule unit store the data recorded for the past 48
hours.
● In VDR (JCY-1900), install both the protective and the float-free. In S-VDR (JCY-1950), install one of
capsules.
● When retrieving the capsule units from the sea, with this 48-hour data recording function, the situation in
the event of an accident can be analyzed by comparing it to that before the accident.
● Addition of the float-free capsule unit makes the retrieval of recording data easier.
5) Data recording in the internal storage (meet the demands of new standard)
The internal storage stores the data recorded for the past 720 hours.
● With this 720-hour recording internal storage, the residual ratio of accident data rises substantially.
● For voyage within 720 hours, all the data during the voyage can be recorded.
6) Audio recording for the bridge
● The 6-track microphone audio function enables recording of conversations in the bridge at 4 places in
addition to the dedicated audio recording in the wing.
● Sound quality is improved (newly designed microphones and re-examined A/D conversion and com-
pression performance).
● Downsized microphone unit and waterproof microphone unit.
7) VHF audio recoding
● The 2-track VHF audio function enables separate recording of No. 1 VHF and No. 2 VHF.
8) RADAR/ECDIS image recording
● The 3-screen capacity for image recording enables recording of 3 screens in total (6 channels at max-
imum) for X band RADAR, S band RADAR and ECDIS.
● Recording image alternately for the same units.
9) Performance test (meet the demands of new standard)
● Checking the latest recorded data is available through the Operation Panel Unit..
(meet the demands of new standard)
