R5
SUPREME - Navigation System MkII
INSTALLATION
7000 118-383, B1 Page 27
The R5 Navigation Sensor is designed to operate on 12-24 VDC. The nominal power
consumed is up to 5.7 W. The R5 Navigation Sensor is internally fused (slow blow fuse) by
a 2A fuse.
The R5 SUPREME CDU is designed to operate on 12-24 VDC. The nominal power
consumed is up to 13 W. The R5 SUPREME CDU shall be fused by a 5A fuse.
The R5 Navigation Sensor has an internal 5A slow blow fuse used for optional powering of
the R5 CDU directly from the sensor. The CDU must be externally fused if powered from any
other source.
Sensor Interface ports
Below ports can be accessed in the R5 Navigation Sensor.
See Chapter 19 for electrical details.
5.9.2.1 Input Ports
The sensor has five unidirectional ports. These ports can be used to connect to external
sensors such as compass, gyro or depth sensors. This either for collecting heading data or
for forwarding data.
To receive data on a port, its RX signals shall be connected to the TX signals of an external
equipment.
It is up to the user to configure the types of messages that shall be received on each port, as
well as the baud rate used for communication.
See section 10.1.16 and 10.1.25 for information about the configurations mentioned above .
These ports are also configurable to detect a discrete alarm acknowledgement, making it
possible to acknowledge all active alarms at once using an external switch.
5.9.2.2 Output Ports
The sensor has eight unidirectional ports that only can be used to output data from the R5
SUPREME Navigation System to external equipment. The TX signals of the port shall be
connected to the RX signals of the external equipment.
It is up to the user to configure the types of messages that shall be sent on each port, as well
as the baud rate used for communication.
See section 10.1.26 for information about the configurations mentioned above.
Note: Combine one input and one output terminal for bidirectional communication
5.9.2.3 Alarm Relay Port
The Alarm Relay port is used to indicate navigational alarms to external alarm signalling and
alarm monitoring systems.
The alarm relay will be active as long as there are no alarm which not received acknowledged
and by that linking Normally Open/Common on the Alarm Relay screw terminal. The relay
will, when an alarm (unacknowledged) gets active, be deactivated and thereby switch link
state from Normally Open/Common, to Normally Closed/Common.
Note: Connection to the Alarm Relay terminal depends of the alarm systems functionality. A
straight audible- or visual indication shall be connected to the Common and Normally Closed
terminal pins.
