Labrie EXPERT Maintenance Manual page 377

Multiplexing 369
The Joystick page allows the operator to check if all functions of the joystick are working correctly. If
one joystick is installed on your vehicle, it will be represented on the monitor display by joystick 127.
However, if two joysticks are installed on your vehicle, any of the two joystick numbers (127 and 72)
can represent either joystick on the screen.
If you press a joystick button, the corresponding button on the monitor will turn green. If nothing
happens, there may be a communication problem between the joystick and the master control
module. Refer to the maintenance personnel or LabriePlus.
Also, if you move the joystick backwards, forwards or sideways, you should see the values under the
illustration changing. If no change occurs when moving the joystick, a communication problem
between the joystick and the master control module may be the cause. Call LabriePlus for support.

J1939
The J1939 page is useful when you need some specific information (e.g. current gear, road speed,
brake status).
Figure 9-16 J1939 page
Your vehicle is equipped with 2 different CAN-based communication buses:
 the J1939 bus, which is used for the chassis equipment; and
 the CANopen bus, which is used for the body.
These 2 communication buses are completely independent of one another, except for some specific
data that are transferred from the chassis J1939 bus to Labrie's Multiplex System in which they will be
used. These specific data are the following:
 selected gear
 current gear
 road speed
 engine RPM
 brake
 parking brake
