Multiplex System

The Firefly Multiplex System provides advanced
automation and mobile electrical solutions for your
touring coach. Firefly is a multiplex network system
that combines multiple signals across a media to
reduce wires and simplify end-user control� The system
combines all desired functions and controls of the
touring coach into a simple touchscreen interface that
allows you to control many systems�
Each button illuminates when pressed, indicating the
circuit is either ON or OFF� The button will turn white
when the circuit is OFF and blue when it is ON� Buttons
controlling circuits such as Light Master and Panel
Lights typically do not change from blue to white�

Systems Controlled By Firefly

• All lights (inside and outside)
• Power awning and awning lights
• Shades
• Roof vent
• Climate
• Generator
• Tank monitoring (Fresh, Black, Grey and LPG)
• Battery voltage
• Water heater
• Tank heaters
• Water pump
There are several touchscreen control panels for the
multiplex system� The central (main) touchscreen
control panel is in the front roadside roof locker, with
remote touchscreens placed throughout the touring
coach� While all screens have controls for all the
major systems, the central panel has additional status
and system information features not found on the
secondary panels� The circuit control board for the
system is below the curbside ottoman�
NOTE
The Multiplex System is self-resetting should a
circuit trip. The owner should never need to reset
the system for any reason. If the main control
panel or remote panels are not operating, this
could indicate a short in the wiring that will require
service by a certified technician.

Multiplex Home Screen/Monitor Panel

The Home screen displays fluid levels of the Fresh
Water, Grey and Black Water, and LPG tanks. All fluid
monitoring systems are factory calibrated to the tank
capacities of each model� Sender pads are installed
and adhered to the sides of the holding tanks� The
sender pads scan the level through the tank wall using
the sender's microprocessor programming�
The Home screen also displays the status and settings
of the major systems of the touring coach, including the
voltage status of the House and Chassis batteries�
Multiplex Secondary Screens
The navigation bar on the left side of the screen allows
you to select from the five secondary screens: Lights,
Electrical, Climate Control, Shades, and Settings (see
next page for examples)� From here, you can navigate
to additional screens that serve a variety of functions�
You may encounter Warning screens when entering
settings. Some Changes will affect functions of the
touchscreens and your touring coach and should
only be changed by a trained technician.

Cleaning the Multiplex Touchscreens

To clean the glass surface of the LCD touchscreens,
power down the system and then gently wipe it with a
soft, slightly damp cloth (using ONLY minimal amounts
water or lens cleaner)� Ensure the LCD is fully dry
before powering the system up again�
The components of the Firefly system must not
be exposed to liquids or moisture of any kind
(including the use of any cleaning agents). The
only approved exception is cleaning of the glass
surface of LCD touchscreens.
