sors radar/ECDIS and records them in the Fixed DRU, Float-free DRU and internal long term de-
vice.
Recording interval of data and audio is as follows:
• Radar/ECDIS video signal: every 15 seconds
• Bridge and VHF audio: real time
• IEC sentences: when received
• Analog and digital data: every second
For VR-7000, you can select one or two 512-GB SSD(s) as internal long term device(s). When
selecting one SSD, you can add another one using an optional SSD kit later.
No. of pcs
1 SSD (512 GB)
2 SSDs (1 TB)
*: The recording interval for 3 channels is 15 seconds, which is compliant with IEC61996-1 Ed.2
and IEC61996-2 Ed.2. Other channels record a maximum of four video signals at intervals of 15
seconds, using the time-division method.
For VR-7000S, there are four save areas (Area1, 2, 3, 4) in the long term device(s). Each area
can record data for 12 hours.
Data Recording Unit
Fixed DRU
The Fixed DRU is housed in a highly visible protective capsule which can withstand a fire of
1,100°C for one hour and deep-sea pressure of 6,000 m.
The underwater acoustic beacon (pinger) on the capsule automatically transmits 10 ms pulses at
37.5 kHz for at least 90 days when it is submerged in water. The expected life of the beacon bat-
tery is three years.
Float-free DRU
The capsule of the Float-free DRU has the same functionality of an satellite EPIRB (Emergency
Position-Indicating Radio Beacon). The VDR data is recorded in the storage module at the bottom
of capsule.
The DCU feeds the VDR data to the bracket of the Float-free DRU through the LAN cable, then
the bracket feeds the data to the capsule by wireless communication.
The capsule of the Float-free DRU is stored in the bracket. When the Float-free DRU sinks to
depths of up to four meters, the capsule is automatically released from the bracket then floats to
the sea surface. At the same time, the capsule starts to transmit 406 MHz signal for locating the
position of capsule and 121.5 MHz signal for homing for at least 168 hours.
Note: Select fixed DRU or float-free DRU for VR-7000S.
Data items to be recorded
Note: If the sensor data is input to the DCU through an external unit (sensor adapter, junction box,
etc.), the input of the sensor data is delayed because of the communication lag between the DCU
and external unit.
