CAN-bus Communications
The TEC communicates with other electrical components (lithium battery
pack, electric motor, and InfoCenter display) on a CAN-bus communication
system. The CAN-bus system reduces the number of electrical components and
connections that are used on the machine and allows the number of wires in the
wire harness to be reduced.
The CAN identifies the controller area network that is used on the Greensmaster.
The 2 twisted wires form the bus. These wires provide the data pathways
between the machine components. The engineering term for these 2 wires are
CAN High and CAN Low. At the ends of the twisted pair of bus wires are the
120-ohm terminator resistors.
The CAN-bus link controls each of the components that requires only 4 wires
to operate and communicate to the system: CAN High, CAN Low, B+ (power),
and ground.
IMPORTANT
The terminator resistors at the ends of the bus wires are required for
proper electrical system operation.
