2Basics
2.1 The LX9xx/LX80xx Series at a Glance
The system consists of two units: the main display unit and the vario unit. Within the main
display unit an integral 50-channel GPS receiver and a high brightness colour display are
fitted. An integrated SD card or USB interface is used for user friendly data exchange.
Some of the models also feature a PDA port for easy connection to an external PDA device.
The main display unit is equipped with a built-in flight recorder according to the most recent
IGC specification for all flights. Optionally the FLARM collision avoidance system can be
integrated into the main display unit.
Main display unit comes in different forms:
•LX8080 model with 2.8” screen and 320x240 pixels resolution,
•LX8000 model with 3.5” screen and 320x240 pixels resolution,
•LX9050 model with 5.0” screen and 800x480 pixels resolution,
•LX9000 model with 5.6” screen and 640x480 pixels resolution,
•LX9070 model with 7.0” screen and 800x480 pixels resolution.
A standard part of system is also the V8 vario unit. It is a most modern Variometer running
on a very powerful processor with inertial platform using 3 axis accelerometers, 4
gyroscopes (for inertial vario, AHRS and wind calculation), smooth audio output with audio
equalizer and integrated synthesized speech output. The unit communicates with the main
display unit via the RS485 system bus. The V8 vario features a 57 mm diameter (2¼")
colour screen and three additional buttons.
Optional vario units are available:
•V80 vario with an 80 mm diameter (3”) colour screen and three additional buttons
•V9 vario with a 57 mm diameter (2¼") indicator with mechanical needle and colour
display for additional data.
Optionally additional vario indicators and a wide range of interface devices can be daisy-
chained using the RS485 bus.

Rev #23 Version 7.10 December 2019
Page 11 of 224
2.1.1 Display Unit Features
Extremely bright colour displays readable in all sunlight conditions with backlight
automatically adapted using an ambient light sensor (ALS).
•Using Linux operating system (not CE Windows) ensures fast and stable operation of the
firmware.
•6 or 8 push buttons and 4 rotary switches (knobs) are used for input, which comprise
the well-known LX user interface. Optionally a remote stick is available for more
comfort.
•Portrait or landscape orientation (portrait orientation is not available on LX80xx models).
•Pre-loaded with worldwide terrain maps, airspace and airport databases.
•Unlimited number of waypoints.
•Unlimited number of tasks (with assigned area support).

•Display of nearest airports and out-landing fields.
•Unlimited number of pilots/profiles.
•Integrated flight recorder according to high-level IGC specification.
•Real-time flight optimisation according to FAI and OLC rules.
•Flights stored in IGC format are downloadable using the integrated SD Card.
•Flight recorder functions include an integral pressure transducer based on 1013 mbar
level for altitude recording, engine noise level sensor, memory to store more than 1000
hours of flights and digital and mechanically security devices to ensure a high level of
security.
•Integrated FLARM collision avoidance system with graphic, sound and voice (optional)
presentation.
2.1.1.1 Touch screen
LX9050, LX9000 and LX9070 devices have a possibility to have a Touch screen module. It is
a multitouch module, which is very useful when configuring device, planning a task,
exploring an airspace or panning around while flying.
Touch screen module is not included, therefore it needs to be specified when ordering a
LX90xx device.

2.1.6 Internal Options
A FLARM module can be built into the main display unit. All necessary connectors are
available on the rear side of the unit (FLARM external indicator, FLARM antenna), which
guaranties the same comfort as with the original FLARM devices. It is very important to
point out that the whole system uses only one GPS receiver and therefore offers a low
power solution.
An Artificial horizon can be enabled on main display unit. The Vario sensor box is
constantly using data from the inertial platform in order to make the vario signal smoother,
however if pilot would like to see the artificial horizon an additional software option to do so
must be purchased.

Rev #23 Version 7.10 December 2019
Page 14 of 224
2.1.7 External Options
By using a RS485 bus system a wide range of optional interfaces can be easily connected to
the basic configuration with minimal installation work. The LXNAV bus system can be
extended easily by use of RS485 splitting units, which allow plug and play connection of
optional devices.
The following units can be connected to the main system:
•Second Seat Device (LX9000D, LX9050D LX9070D LX8000D or LX8080D):
The unit installed in the rear seat of the glider is powered and receives all necessary
data from the main unit. The communication between both units is exclusively via the
RS485 bus system.
•Remote Control: An extremely ergonomic leather-coated handle which includes 8
push buttons to operate the main display unit and also two additional buttons with open
wires. These two buttons can be used for instance as PTT for radio and SC/Vario
changeover command. A second remote control can be installed to control the second
seat device or for side by side operation.
•Electrical Compass Device
•Secondary Vario Indicators (I8, I9 or I80 indicator)
•Flap sensor
•MOP box for jet engines
•232 Bridge for radio or transponder
•Wi-fi module
•External FLARM module
•Touch option

2.1.8 Simulator
There are two options to stay in condition and familiar with your system. LXSim is a free of
charge program, which you can download from www.lxnav.com or data from the Condor PC
flight simulator (www.condorsoaring.com) can be received via the RS232 port after entering
suitable passwords (see Chapter 5.1.14).
These features are extremely useful for pilots who want to learn about the system and also
wish to refresh their knowledge after a winter break. Please note that altitude data will be
sent from the simulator which means that real final glide training will be possible.
