4. Mechanical Installation
Upon delivery, undertake visual inspection of the package contents for signs of transport damage and
verify the information on the type plate sticker against your order. Do not open the device housing.
For longer storage of the device, select a dry and clean environment. Make sure that the device is not
stored near strong heat sources and that no metal chippings or other dirt can get into the device or its
connectors.
4.1 Display Unit
The display unit is mounted either in front of the instrument panel or behind the instrument panel.
Second variant needs a rectangular cutout (dimensions in Table 3-1). Two mounting examples are
shown in Figure 4-1 and Figure 4-2.
Figure 4-1: Front side mounting
Figure 4-2: Rear side mounting
4.2 Sensor Unit
The sensor unit can be mounted behind the instrument panel or in the fuselage. By default, the anemoi
is delivered with a 0.5 m (3.0 ft) wiring harness kit. As an accessory, a 3.0 m (10 ft) wiring harness kit is
available. The sensor unit is mounted with 4x M4 screws. The screw hole positions can be taken from
Figure 4-9.
The mounting position of the sensor unit is shown in Figure 4-3.

Figure 4-3: Mounting cutout sensor unit
The sensor unit needs to be aligned with the aircraft axes by the following margins:
- Yaw axis: +-1°. Misalignment leads to inaccurate wind indication during longer straight flight
segments without moderate changes in airspeed and heading.
- Roll axis: +- 3°. Misalignment leads to permanent offset of the roll angle indicated by the artificial
horizon (AHRS), and potentially falsifies wind indication during longer straight flight segments.
- Pitch axis: +-7°. Alignment can be adjusted and chosen within a relatively wide-angle range with
no noticeable effect on wind indication. The mounting pitch attitude of the sensor unit will be
indicated as “zero pitch”on the artificial horizon (AHRS).
The sensor unit must always be mounted so that the labeled side of the device is “up”. A vertical
mounting is not possible.
The sensor unit can be mounted in four different yaw orientations, indicated as A, B, C, D on the top
side of the sensor unit. If the sensor unit is installed with direction A pointing in the DOF (direction of
flight) no further action is required upon installation. If the sensor unit is installed in the directions of
B/C/D, the DOF must be set in the menu once after installation, as explained in chapter 6.3: Setup
Menu under “Align DOF”.
Three-dimensional CAD-models of the units and the cutout of the display unit are available at the RS
Flight Systems website.
As waste heat is dissipated via free convection, leave at least a 5 mm gap from the aluminum surfaces
to any other object. Forced cooling is not necessary.
The installation must be in accordance with the appropriate guidelines approved by the respective
aviation authority. The person installing the device is responsible for compliance with all applicable
legislation.

4.3 Temperature sensor installation
It is recommended to install the temperature probe as closely to outside air temperature (OAT) as
practically possible, e. g. inside the nose tip or in the front air vent of the aircraft.
Errors in temperature measurement (usually, too warm measurement due to heating from cockpit
systems) can have an impact on the airspeed calibration and therefore negatively influence wind
calculation. However, the system’s sensitivity to temperature errors is quite low, and the anemoi
software is even capable of adjusting to permanent temperature measurement offsets within the first
15 minutes after takeoff. Nevertheless, good temperature measurement is necessary for ideal
performance of the wind indication.
4.4 P_TOTAL and P_STATIC Connectors
P_TOTAL must be connected with the total pressure tube, P_STATIC with the static pressure tube. The
pressure connectors and pressure tubes need to be properly sealed as leakage leads to errors in the
external airspeed indicator and altimeter. During pre-flight check both instruments need to be checked
for their proper functionality.

5. Electrical Installation
The sensor unit has six electrical connectors and two pressure connectors on the front side. The front
side of the sensor unit is shown in Figure 5-1. Label, type of connector and usage are listed in Table
5-1. Before powering up the unit for the first time, carefully check your wiring.
There is one microSD slot to update the firmware, one RJ45 connector to import GPS data from the
NMEA output. There is also an optional DIN-style connector for an external GPS receiver to import GPS
data. The P/N of the mating GPS receiver is listed in Table 3-2. Two RJ12 connectors transmit data to
the external displays. The D-SUB Power connector is the main connector to power up anemoi. As
shown in the pinout, see Table 5-1 below, D-SUB has power input and an external temperature sensor
wired to it.
GPS data can be provided by a GPS receiver or a device with NMEA output. Make sure that only one is
connected to the sensor unit. Never plug in both, NMEA output and GPS receiver, simultaneously.
If there is an NMEA output device: make sure to use the RJ45 splitter to split up the power supply and
the data lines. The RJ45 data cable is connected directly to the sensor unit in the GPS NMEA slot. The
RJ45 power cable is connected to the default NMEA output power source.
If there is no NMEA output device: plug in the GPS cable in the GPS receiver slot. Place the GPS receiver
in a spot where it has maximum optical visibility of the sky, e. g. the glare shield on top of the
instrument panel. Poor GPS reception has a negative impact on the operation of the unit. It impairs
the accuracy of the wind vector and of the ground speed data.

-The RJ45 connector has the standard IGC pinout, however only the pins Rx (anemoi receives
data) and GND are actively used. anemoi does not supply or consume power nor send data
(Tx) via the NMEA RJ45 connector.
-If anemoi is operated in parallel with other devices on the RS-232 NMEA bus, a 1:1 Y-
Adapter can be used to split the signal. The P/N of the 1:1 Y-Adapter is listed in Table 3-2. As
anemoi merely receives but does not send data on the Tx line, it is not required to detach
the Tx line from anemoi to avoid multiple devices sending on the same line.
-Make sure that the NMEA sentence “GPRMC”(standard navigation data) is included in the
output of the source device. In most cases no action is actively required to ensure sending of
this sentence, as it is the most fundamental content in the NMEA protocol.
-The Baud rate of the RS-232 NMEA data stream must be one of the following: 9600, 19200,
38400, 57600, 115200 bps. If this is the case, anemoi will automatically adjust to the correct
Baud rate.
The extended pin allocation of the RJ45 GPS NMEA connector is shown in Table 5-3. A picture with
the pin numbering is shown in Figure 5-3.

5.3 POWER Connector
The sensor unit uses a standard D-SUB 9 connector. Pin 1 is supplied with +12 VDC, Pin 5 is ground.
Pin must be fused with a 1.0 A circuit breaker. The P/N of the circuit breaker is listed in Table 3-2. The
anemoi is delivered with a prewired power connector harness, including two power cables and the
temperature sensor.

6. Operation
In this chapter operational procedures for the anemoi are described.
6.1 Startup
The anemoi starts up as soon as the required supply voltage is provided. The subsequent startup
screen is displayed for 2 seconds. The startup page is shown in Figure 6-1. The startup page gives details
about the current software version while internal testing routines are performed to ensure correct
operation of all electronic components and sensors (TMP, GPS, PRS, IMU). The color
(green/yellow/red), see Table 6-1 for explanation, indicates the state of the respective sensor.
