SEN 1, 2, 3 ports - Sensors
The Sensor input port can be configured to receive data from the Gyro, the GNSS used for
navigation and the LOG. Each of the three sensor (SEN1, SEN2 and SEN3) ports can be
independently configured to receive information from one of these sensors. Alternatively ALL
sensor information can be received via ONE of the sensor ports.
The sensor ports require configuration before use; this is described 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
Recommended cable for connection of Sensors:
Single twisted pair, shielded, PVC sheathed.
Cable length to display Required dimension
0 – 100 metres 0.8 mm
2
each wire
Sensor wire connection
The twisted pair shall be assigned as RxA and RxB
SEN Ports necessary sentences:
The basic requirements are:
IEC 61162-2 standard
ITU-T V.11 electrical properties
Speed can be configured from 1200 - 38400 bits/sec
Data bits 8, Stop bits 1, Parity none
All required as well as optional sentences are listed in the table; ensure that the connected
sensor transmits at least the required sentences (as given by IEC 61162):
