CAN--bus Termination Resistors
Systemcommunicationbetween electricalcomponents
on Greensmaster Hybrid TriFlex machines is accom-
plished on t wo (2) CAN--bus communication systems.
Two (2) speciallydesigned, twisted cablesformthe bus
for both of the networks used on the Hybrid machines.
These wires provide the data pathways between ma-
chinecomponents.Attheendsofthe twistedpairofbus
cables are 120 ohm termination resistors.
The resistors plug into the wire harness in the following
areas:
A. The two (2) termination resistors for the main
electricalsystemon Greensmastermachines arelo-
cated near the hydraulic lift control manifold under
the right side cover next to the operator seat.
B. The two (2) termination resistors for the E--Reels
electrical circuit are located near the wire harness
connectors for the RH and LH cutting reel motors.
NOTE: Refer to the Electrical Schematics and Wire
HarnessDrawingsinChapter10 -- Foldout Drawingsfor
additional information on termination resistor locations
and wire connections.
IMPORTANT: The termination resistors at the ends
of the bus cables are required for proper electrical
system operation.
Resistor Test
The termination resistors (Fig. 79) 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 Hybrid
TriFlex machines.
