Technical features
The Fidelix FX-AirRECEIVER is a unit that collects
data from wireless M-Bus devices and oers it to
external Modbus clients as a Modbus TCP-server.
Alternatively, the wireless M-Bus data can be sent
to the cloud by using the 4G/5G network or a
wired landline. The unit has two internal antennas
for improved range. The FX-AirRECEIVER is
meant for indoor installation in residential and
commercial properties and is to be powered
with 230 VAC.

Placement:
The indoor range between the Fidelix FX-AirRECEIVER and a
wireless M-Bus transmitter device is normally 50 to 100m.
The range depends largely on the building type and construction
method. In general, the following applies:
• Place the product as centrally as possible with in the area to
be covered. For large areas, multiple receivers or repeaters
may be required.
• Avoid placing in cold areas.
• Avoid placement close to electric cables or other metal
elements. Keep a distance of 20cm around the unit. This also
applies below the unit but obviously not the cables required
to connect the unit.
• The product is constructed to be installed on concrete walls
but a better range is achieved when installed on wood or
drywall.
• New buildings with prefabricated wall elements and low-
energy windows have a strong influence on the wireless
range and can require closer placement to the receiver.

Operation:
Start the unit by connecting the power.
The unit’s LEDs are activated for 1-3 minutes flashing a red/green sequence before changing to a fixed light for 10 minutes.
Fixed green light = functioning
Red light = malfunctioning
Description of the LEDs:
The LEDs indicate that the installation is correct as well as confirm that the unit is functioning correctly during its whole lifespan.
The unit has three red and green LEDs. The LEDs are visible through the cover and thus can be seen without opening the unit.
In normal operation, these LEDs are unlit and can be activated by placing a magnet (such as a fridge magnet) on the upper corner
of the unit or by pressing the LED button. After the unit is connected, the LEDs light up for 10 minutes before going out. The LEDs
give information about the status of the unit.
In general, a green light indicates a functioning unit, a red light indicates a fault and a
flashing green/red light indicates that the status is not yet available. An unlit LED means
that the function is inactive e.g. a unit configured for 4G/5G will have an unlit Ethernet
light.
