Can--Bus Termination Resistors - Toro Greensmaster TriFlex 3300 Service Manual

CAN- -bus Termination Resistors
System communication between electrical components
on Greensmaster TriFlex machines is accomplished on
Termination
A
B
a CAN--bus communication system. Two (2) specially
Resistor
designed, twisted cables form the bus for the electrical
system. These wires provide the data pathways be-
tween machine components. At the ends of the twisted
pair of bus cables are 120 ohm termination resistors.
The resistors plug into the wire harness near the hydrau-
lic lift control manifold under the right side cover next to
the operator seat.

NOTE: Refer to the Electrical Schematics and Wire
Harness Drawings in Chapter 10 -- Foldout Drawings for
additional information on termination resistor locations
and wire connections.
Resistor Test
The termination resistors (Fig. 58) can be individually
tested using a digital multimeter (ohms setting). There
should be 120 ohms resistance between terminals A
and B. Terminal C is not used on Greensmaster TriFlex
machines.
