3. UNIT DESCRIPTION
The IFD-NET EVO EMS interface is based on a double concentric
rotary knob with a push switch that gives access to all the
settings the pilot needs during the flight, and allow to adjust
the setup’s parameters.
On the right side of this page is shown the main page of
instrument.
Spinning the big crown rotary knob will show other sensors (if
set) on the center-right part of the screen. Spinning the little
crown rotary knob will show other sensors (if set) on the low
part of the screen.
The pilot can access the main setup by keeping pressed the
knob for about 2 seconds until the screen, shown on the
right, appears.
Within setups, by rotating the little rotary knob’s crown,
moves the selection up and down, and tapping button
confirms the highlighted selection.
IFD-NET EVO is available in three different models:

In order to realize a network, IFD-NET EVO EMS can be classified in:
Master: It consists in a single unit witch capture and visualize various engine data and
generate a RS485 pack data that will be used from slaves connected to the bus.
Slave: The unit reads data from RS485 BUS

Sensors setup
4.2.3. SENSOR SETUP
EVO EMS is able to read up to 12 sensors configurable according to the model.
Like Thermocouples, through the SENSORS setup it is possible to link the physical input of the
sensor to its logical function.
The characterization of the sensor can be done in two ways:
1. Selecting a specific sensor model from the internal database (parameter SENS)
2. By inserting customized characteristic (parameter TYPE) and curve (parameter CURVE)
Settings of Sensors menu
EXIT: Come back to main setup
PARAMETER: Type of measurement required. The
available values vary depending on the model
TYPE: sensor construction technology. Valid only if
the SENS parameter is not active. Possible values:
V (Voltage Sensor)
I (Current Sensor)
R (Resistive Sensor)
SENS: Sensor model (See 10 SENSORS LIST).
RES: External parallel resistance applied (See
5.4.4CURRENT SENSORS NOTE).
CURVE : Manual setting of the sensor characteristic curve
(See 4.2.6 CURVES SETUP).
If sensor PARAMETER is F LEV (fuel level) this voice
became CALIB
ARCS : Set coloured arcs (See 4.2.8 ARCS SETUP)
