2.2.2 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 4.6 (IMO MSC.163(78) 5.4).
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:
2) Protocol:
b) Sensor data input :
1) Input channel:
2) Data input interface:
3) Recording interval:
Stop to record data to PCU
Restart to record data to PCU
Stop to record data to CF card.
(enables to take out CF card from RCU)
Recording / Recording stop
Recording / Recording stop (enables to take out CF card)
Access error to CF card
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
When radar images cannot be recorded, the output data of AIS must be
recorded as a substitute.
However, JCY-1850 can also record both AIS data and radar images.
