Located near the bottom of the control board are
two connections, one for the front handlebar display
communications and one to the rear connection panel
for the rear handle bar display communications.
The two small LEDs (D36 and D37) above the front
handlebar connection on the left will flash every
few seconds to indicate whether send/receive
communication is occurring between the front
handlebar display and the Control Board. (Circled in
picture on the left). The two small LEDs (D38, D39)
above the connection to the rear panel on the right
for the rear handlebar connection, function the same
as the front .
Troubleshooting Communication Issues
Handlebar display power, display information
and communications is provided by the mini USB
connection at the bottom of the display.
If a handlebar communication cable is disconnected,
has a bad connection or is damaged, the display
may still boot up past the splash screen. However,
the touch screen will not update or change anything
when touched. The handlebar switches are connected
with the big white connectors with many white
and yellow wires at the Control Board. Handlebar
functions may work when the buttons are pushed
on the handlebar, but the displays will not update
without communications. These big connectors also
enable power to be sent to the displays, so, if they
are damaged you may not have any display or switch
control .
Possible Solutions:
• Try re-booting the machine to see if the problem is
corrected .
• If not, inspect the communications cable that con-
nects to the front board . (circled, bottom)
• Check the cable connection at the front board at
both the front board inside the nose cover, and at
the display . (circled, top)
• If necessary open the machine front cover and
check the front and rear communication cable con-
nections on the Control Board.
