FLYBOX

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.

Up to 16 Omnia57 can be connected together through
the CAN 1 bus.

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.

Omnia57 Family System Overview

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.

1.6 INTERFACES

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.

If the current on one of the
outputs is too high, a caution
message will appear.

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.

Caution!

2.2 FUEL FLOW SENSORS 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

FLYBOX

● 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.

Tank cap: set the total capacity on-board as the sum of
all the usable fuel in all tanks. (range 0-500lt, 0-132 gal.)

K-factor: the K-factor of a fuel flow transducer is the
number of electric pulses for 1 gallon of fuel flown (if you
have the K-factor in liters you must multiply this value by

3.78 before set k-factor parameter in the instrument).
If you are using the RED-CUBE FT-60 flow sensor Flybox
code 503030, make sure the K factor is 68000.
If you are using another kind of Fuel Flow sensor, make
sure about his compatibility of the electrical signals of
amplitude and frequency and follows the manufacturer
instructions to set the right K-factor in the “K-Factor”
parameter.
The K-factor can be manually modified or automatically
calculated with the “K-fact calib” function. It's
recommended also to execute the K-factor calibration as
soon as possible to have the maximum accuracy (refer to
chapter 4.5.1 “K-fact calib”).
To manually edit the K-factor select and click on the

4.5.1 K-Factor Calibration

NOTE: it's recommended to perform the calibration right after

installing the instrument.

1- With the aircraft in level attitude, fill the tank/s of fuel; note
that in the step #4 it's required to refill the tank/s at the exact
level reached here.

2- Turn-on the instrument and select “FILLED” when asked for
the fuel quantity.

3- Burn at least 1/2 of fuel in the tank/s: a greater amount of
burned fuel will increase the accuracy, and you can do this step
in more flights: at the beginning of each flight you must not add
fuel in the tank/s and you must select “NO REFUEL” when
asked after turning on the instrument.

FLYBOX

4- Fill the tank/s with the exact same level reached in the step
#1, accurately measuring the quantity of fuel added in the tank/s.

5- Turn on Omnia57 Fuel Comp and select “NO REFUEL”
(even though you have refilled it’s required to select “NO

REFUEL”).

6- Select K-Fact Calibration, the following screen will appear:

7- In the “FUEL FILLED” field, now insert the exact
quantity of fuel you have added and measured in step #4;
probably it doesn't correspond exactly to the “FUEL USED”
because this is the measurement from the transducer not
yet calibrated and it’s showed for reference only. To insert
the value, rotate the knob and press it to confirm. To exit
without saving, press the knob for 3 seconds.

8- As soon as confirmed, the display will briefly show the
newly calculated K-factor and return to the Fuel computer
menu. The transducer is now calibrated and the K-factor
is automatically stored in memory.

During later refuelling, it will be important to check that the
fuel computer indication is correct. If the indication is very
far from reality you can re-calibrate or manually change
the K-factor.

CAUTION: Each time the fuel computer calculates the
remaining amount of fuel, there will be an error due to the
fact that the K-factor is not mathematically perfect. These
errors, although small, will be added in the same direction
and this will lead after several refueling to have an
increasingly larger error. This error is reset every time you
fill up with fuel, confirming the "FILLED" function. For this
reason it is advisable to fill up when possible to reset the
errors.

NOTE: The first time you switch-ON the Omnia57 Fuel
Comp, the fuel pressure gauge will not be enabled, so if

you have the fuel pressure sensor installed, enable it as
explained in the chapter 4.5.2.
