Below signals can be accessed in the R5 NAV Junction box, or using the R5 Signal
Cable DSUB-OPEN.
See Chapter 13 for electrical details.
2.8.3.1 Sensor Port
The Sensor port is used to connect to the R4 Navigation Sensor unit. The Tx signals
of the port shall be connected to the Rx signals of the System port on the R4
Navigation Sensor. The Rx signals of the Sensor port should be connected to the Tx
signals of the System port on the R4 Navigation Sensor.
2.8.3.2 User Port 3 and User Port 4
Theses ports are bidirectional and can be used to connect to external equipment
and sensors, such as a compass or depth sensor.
To receive data on the ports, their RX signals shall be connected to the TX signals
of the external equipment.
For an external equipment to receive data from the R5 SUPREME Navigation
System via the ports, the TX signals of the ports 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 and
received on the ports, as well as the baud rates used for communication.
User Port 3 and User Port 4 on the R5 SUPREME CDU are high-speed ports with
isolated power and ground. They
can be used to interface equipment in a ―high-
speed craft‖ installation for output of NMEA GPS sentences. All user port baud rates
and sentence outputs can be configured via the R5 SUPREME CDU.
