Omnia57 Family System Overview
The Omnia57 instrument family has many innovative
features, common to all models as described below.
OMNIA57 FAMILY SYSTEM OVERVIEW

alloy, CNC milled and powder coated to last a long time
over the years always showing a new appearance.
- Large 2.4 inch TFT display, 320x240 Pixels, 1000 nits,
antiglare surface, sunlight readable, wide temperature
range.

Omnia57 Family System Overview
1.3 INTERCONNECTION ABILITY
All the instruments of the Omnia57 family can be
connected together to form a communication network,
making some data exchange operations simpler.
The software update of a Omnia57 instrument connected
in group takes place through the CAN bus communication
with the instrument that has the USB pen drive connected.
This means that the USB connection is made to a single
instrument, and the information will be forwarded via CAN
bus to or from all the others in the group.
The configuration data and the data logger of the
interconnected instruments are saved or restored via CAN
bus on the same USB pen drive. A single brightness sensor
can provide information to all the connected instruments
to automatically adjust the backlight intensity.
Up to 16 Omnia57 can be connected together through
the CAN 1 bus.

1.4 EASY SOFTWARE UPDATE
The user can download any new firmware, when available,
from Flybox website, connect a USB pen drive to the
instrument and freely update it with the last features.
With one USB connection only, it will be possible to update
every instrument installed in the panel. If more Omnia57
are installed and properly connected, they will search for
the right firmware through the CAN bus.
1.5 EASY DATALOG SAVING
Easy logging of the data for debug purpose. If needed,
each Omnia57 unit can save a last flight log on the USB
pen drive. The user can then send the log via e-mail to
Flybox support for a help/support request.

Omnia57 Family System Overview
All the Omnia57 instruments have the following common
interfaces:
2 separate CAN BUS: they can be used to connect the
Omnia57 instruments together, to interface them with
other Flybox instruments or with external devices like
Engines ECUs or new devices that will be possibly
developed in the future.
2 RS232 serial ports: used to connect the Omnia57
instruments to an external GPS (when applicable). This
feature appears in some models only.
1 Sensor Light Input: if connected, it allows the automatic
light intensity adjustment, one sensor for all the
instruments.
2 Power outputs for sensors: one 12 V 500mA@60°C
and the other 5 V 350 mA@60°C, both protected from
short circuit.
1 Alarm output: all the Omnia57 instruments can activate
an external warning device like a lamp or a small relay
through this NPN transistor output.
1.6 INTERFACES
Caution!
High current PIN 2
If the current on one of the
outputs is too high, a caution
message will appear.

Mechanical installation
MECHANICAL INSTALLATION
The Omnia57 Fuel Comp instrument fits in a standard
2 ¼” (57 mm) panel cutout; it's recommended to choose
a position that permits optimal display visibility. It's
furnished with four M4 screws to install it to the panel, if
you use other screws consider that the maximum thread
length inside the instrument body is 10mm (see the picture
below).

Mechanical installation
Omnia57 Fuel Comp has 2 fuel flow sensor inputs.
If your installation includes a flow of fuel returning to the
tank, you can install the second flow meter obtaining a
differential measurement.
The input 1 is dedicated to measuring fuel flowing from the
tank to the engine and the input 2 is dedicated to
measuring fuel returning from the engine to the tank. The
flow of sensor N. 2 is subtracted from the flow measured
by sensor N. 1 and the resulting amount represents the
instantaneous flow of fuel burned.
Omnia57 Fuel Comp accepts all flow meters as long as
they meet the characteristics listed in the technical
specifications, see pag 48.
The standard one supplied from Flybox is the code 503030
EI FT-60 (RED-CUBE).
To install the fuel flow sensors, follow the manufacturer's
instructions included in the sensor package, together with
the general recommendations below.

Mechanical installation
●Install the sensor with the wires pointing up.
●Respect the IN and OUT port labelled on the sensor
body.
●Do not install the sensor close to high temperature
objects like the exaust system or others and if needed
protect the sensor with firesleeve material.
●Do not use teflon tape for the inlet and outled ports,
use liquid sealant only.
●Never clean the sensor by blowing compressed air into
it.
●Install a filter in the fuel line before the sensor.
●The tubes before and after the sensor should be
straight for at least 4/5 cm to avoid turbulence in the
fuel and inaccurate flow data.
●Check for leakage after system starts.
●Do not clamp the sensor directly to the engine,
vibrations could damage it.
●Follow the instructions supplied from the sensor
manufacturer.
