DOC No. 7ZPJD0387C
2) Data input interface: IEC61162-1/-2 (RS-422)
3) Recording interval: depends on the input from the sensors (normally 1 second)
c) Bridge audio input:
1) Input channel: up to 9 (channels)
2) Input sensitivity: 6kHz
3) Recording interval: continuous (1 audio file / minute)
d) VHF communications input (audio):
1) Input channel: up to 3 (channels)
2) Input sensitivity: 3.5kHz
3) Input level: 0 dBm 600-ohm balance
4) Recording interval: continuous (1 audio file / minute)
e) Radar image data input (input of No1. X band radar is recommended):
1) Input channel: 2 (channels)
Auto selection of a radar image from both channels
(If the radar is of JRC make, automatic selection of on-operation radar
is possible.)
2) Input interface: analog RGB/Hs/Vs
- RGB: 0.7Vp-p (video signal)
- Hs: TTL
- Vs: TTL
3) Resolution: 640 x 350 – 1600 x 1200 pixel (conforms to VESA DMTS)
4) Refresh rate: 60 - 85 Hz (conforms to VESA DMTS)
(Resolution 1600 x 1200 pixel 60Hz only)
5) Recording interval: 1 image every 15 seconds
f) Recording data backup:
1) Media: CF card
(Adapter for PCMCIA type-2 is attached to the RCU.)
2) Storage capacity: 2.0GB
g) Blackout processing:
1) Recording duration: 2 hours while blackout
(during the blackout, only the conversation in the bridge is recorded)
2) Restoration time required: less than 1 minute
(Recovery time from blackout operation to normal operation on
restoration of ship’s generator.)
h) GPS select signal input:
1) Interface: Dry (voltage free) contact closure
(Commonly used with External Contact Input )
2) Operation: Recording GPS selection (active open/close)
i) RADAR select signal input: (Only JMA-9900, JMA-900M, JMA-5300
1) Interface of JRC radar: IEC61162-1 (RS-422)
2) Operation of JRC radar: Active radar selection by JRC original sentence
3) Interface of other radar: Dry (voltage free) contact closure
(Commonly used with External Contact Input )
4) Operation of other radar: Recording RADAR selection by dry contact closure (active open/close)
j) External Contact Input (dry contact):
1) Number of input: maximum 3 dry contacts (voltage free)
(Commonly used with the input signals which select RADAR or GPS.)
2) Output sentences: Registers sentences at the time of their making and opening
