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.
