What is CAN bus?
CAN bus is a communication protocol (NMEA2000 compliant) that shares multiple
data and signals through a single backbone cable. You can simply connect any CAN
bus devices onto the backbone cable to expand your network on-board. With CAN
bus, IDs are assigned to all the devices in the network, and the status of each sensor
in the network can be detected. All the CAN bus devices can be incorporated into the
CAN bus network. For detailed information about CAN bus wiring, see “Furuno CAN
bus Network Design Guide” (Type: TIE-00170) on Tech-Net.
How to ground the FI-70
1. Fabricate a grounding cable (IV-1.25sq., local supply) with a close-end terminator
(local supply).
2. Connect the close-end terminator to the rear of the FI-70, as indicated in the figure
on the previous page.
3. Connect the loose end of the grounding cable to the ship’s ground.
5.2.2 How to connect to the Wind Transducers FI-5001/L
The IF-NMEAFI Analog Data Converter is required when connecting the Wind
Transducer FI-5001 or FI-5001L, in order to convert the analog data from the sensor
to CAN bus/NMEA2000 format data. When connecting the FI-70 to the FI-5001 or
FI-5001L, use the terminal box included with the FI-5001 or FI-5001L.
For details on installation of the IF-NMEAFI and FI-5001 or FI-5001L, refer to the
Installation Manual (IMC-72661) or Installation Guide (C72-01403).
Note: If the FI-50 series use the wind transducer’s data converted by the analog
NMEA data converter, change the setting for wind data selection on the Setup1 menu.
For how to change the setting, see the Operator’s Manual of the FI-50 series.
