Wiring; How To Connect The Unit - Furuno FI-70 Operator's Manual

5.2

Wiring

The FI-70 is able to display information from various sensors. The typical configuration
example shown in "SYSTEM CONFIGURATION" on page vi uses the optional data
converter (IF-NMEAFI) to show information from the analog sensors. The FI-70 is part
of a network, connected via a CAN bus/NMEA2000 backbone.
For detailed information about CAN bus wiring and configuration, see the "Furuno
CAN bus Network Design Guide" (TIE-00170-*) on FURUNO Tech-Net.

How to connect the unit

Cable assy.
(M12-05BM+05BF-060, 6 m)
To CAN bus/NMEA2000
network backbone
Ground wire
(IV-1.25sq., local supply)
NMEA2000 port
Using the supplied cable assembly, connect the FI-70 to the CAN bus/NMEA2000
network backbone. The FI-70 must be on the same network as the sensors you wish
to connect to. Power is also supplied via the CAN bus/NMEA2000 backbone to the
FI-70.
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.
