For Marine alternator applications a CAN Bus compatible alternator regulator option is the:
•
Wakespeed WS500
Using a CAN Bus compatible alternator regulator is preferable as it offers more control
versatility.
The CAN interface can provide the following functionality to compatible devices:
1.

The CAN 2.0 Part A and Part B standard uses the SAE J1939 standard in the LiTE. It is necessary
to install a 120 Ohm resistor on each extreme end of the CAN cable (spliced to not require a
resistor). Most devices operating on CAN have two plugs to connect in and then out again on
the CAN Bus. The first and the last device in the chain must have a termination resistor
plugged into the spare (second) plug. The LiTE resistor plugs are available from the inverter
manufacturer and from Freedom Won. Where one LiTE is installed or where it is the end of
the line CAN device,
the LiTE must be fitted with a termination resistor.
The LiTE is supplied with a termination resistor as standard. The other devices must be fitted
with the correct termination resistor for that particular brand because the pin configuration
may differ from the battery plug.
The third-party device manuals must be referenced for all details regarding connecting the
CAN interface. Also refer to the Freedom LiTE Home and Business manual for more CAN Bus
pin connection information.
Most brands use 500kbps. If 250kbps is required it is available on the LiTE with a specific
profile loaded, which must be requested when ordering the LiTE or can be loaded during
commissioning by your distributor for Freedom Won technical support.
