6.4.7 SEN 1, 2, 3, 4 ports - Sensors
Sensor input ports can be configured to receive serial data from the Gyro (or Gyro Converter),
the external GNSS used for navigation and from the LOG. Each of the four sensor (SEN1,
SEN2, SEN3 and SEN4) ports can be used to receive information from one of these sensors.
Alternatively, all sensor information can be received at any one of the sensor ports provided that
the information is first multiplexed.
The sensor ports require configuration before use; this is outlined in the Commissioning Guide,
section 12, and described in detail in the Operation Manual.
The AIS must be connected to:
• The GNSS unit used for navigation
• The gyrocompass providing heading information
If available the following information can be connected to the AIS:
• Rate-Of-Turn (ROT)
• Speed over ground from bottom-referenced log
Sensor wire connection
The twisted pair shall be assigned as RxA and RxB
