16
DOC No. 7ZPJD0387C
1.10.3. Recording Control Unit: RCU (NDV-1800/1850)
1.10.3.1. Operation Panel (Internal)
(1) Performance:
a) Button operation:
1) Recording stop: Stop to record data to PCU
2) Recording restart: Restart to record data to PCU
3) Card recording stop: Stop to record data to CF card. (enables to take out CF card from RCU)
b) LED Indication:
1) Recording status Recording / Recording stop
2) CF card status Recording / Recording stop (enables to take out CF card)
3) CF card Media error Access error to CF card
1.10.3.2. Data Processor Unit
(1) Function:
a) Control of recording navigation and hull data to PCU.
b) Collects data of navigation and hull condition according to IEC61162-1/2.
The data collected are as follows according to the IEC61996-2
1) Date and Time (UTC)
2) Ship’s position measured by the electronic position fixing system
3) Ship’s speed (over ground/water)
4) Ship’s heading with a gyrocompass or magnetic compass
5) Under keel clearance
6) Main alarms (indicated in the bridge)
7) Rudder order and response data
8) Engine order and response data
9) Hull opening status (for RO-RO passenger ships and ferry ships only)
10) Watertight door / Fire door status
11) Bow acceleration and hull stress data
(only for the ships mandatorily having hull stress indicator)
12) Wind direction / wind speed data
(only when the vessel is equipped with anemometer)
13) AIS data (S-VDR)
When radar images cannot be recorded, the output data of AIS must be recorded as a
substitute.
However, JCY-1800/1850 can also record both AIS data and radar images.
In case of S-VDR:
If the sensor outputs no data by IEC61162, items 5)-12) are not recorded.
c) Capturing, encoding and recording of conversation audio on the bridge, VHF communications audio and radar
image shown on the display.
d) Copying the recording data to the CF card.
e) Monitoring and control of the system.
(2) Performance:
a) Communication to PCU:
1) Standard: IEEE802.3 (10Base-T/ 100Base-TX )
2) Protocol: TCP/IP
b) Sensor data input :
1) Input channel: NDV-1800 (VDR): up to 32 (channels)
NDV-1850 (S-VDR): up to 16 (channels)
