2Basics
2.1 The LX90x/LX80x Series at a Glance
The unit includes an integral 50-channel GPS receiver and a high brightness colour display.
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 compliant with 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:
•LX808 model with 2.8” screen and 320x240 pixels resolution,
•LX800 model with 3.5” screen and 320x240 pixels resolution,
•LX905 model with 5.0” screen and 800x480 pixels resolution,
•LX900 model with 5.6” screen and 640x480 pixels resolution,
•LX907 model with 7.0” screen and 800x480 pixels resolution.
Optionally additional vario indicators and a wide range of interface devices can be daisy-
chained using the RS485 bus.

Rev #2 Version 7.10 January 2020

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 the 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 LX80x models).
•Pre-loaded with worldwide terrain maps, airspace and airport databases.
•Unlimited number of waypoints.
•Unlimited number of routes.
•Comprehensive flight and route statistics.
•Display of nearest airports.
•Unlimited number of pilots/profiles.
•Integrated flight recorder according to high-level IGC specification.
•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.
2.1.2 Interfaces
•The RS232 interface has NMEA output for external devices.
•An SD Card interface.
•A USB slot for data transfer using USB memory stick.
2.1.3 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. If pilot would like to see the
artificial horizon an additional software option to do so must be purchased.

Rev #2 Version 7.10 January 2020
Page 10 of 145
2.1.4 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:
•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.
•Wi-fi module
•External FLARM module

2.1.5 Simulator
There are two possibilities to become 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 Section 5.1.10).
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.

4System Description
The main display unit of the LX90x series can be mounted with portrait or landscape
orientation. After installing the main display unit, the orientation must be defined via the
Display menu. The main display unit of the LX80x series units can be mounted only in
landscape mode.
In this manual all screenshots are given for portrait orientation of the LX900
system, which is the most commonly used unit. However, all functionality is the
same in any other configuration of system. Minor differences are shown further
in the manual.
4.1 Rotary Switches and Buttons
The following controls are mounted on the front face of the main display unit:
•Four rotary selector knobs
•Eight (lx90x) or six (lx80x) push-buttons
•SD card reader.

4.1.2 Portrait Orientation
4.1.3 Buttons
All buttons have a dynamic function; the first time one presses each button its function is
displayed without executing any action. Not all buttons have a function on every page. In
some cases, buttons have a long press function.
4.1.3.1 Power Button
The power button is marked with the ON/OFF symbol. It has multiple functions. Primarily it
is used to switch the system on and off.
4.1.4 Rotary Switches (Knobs)
The main display unit has four rotary knobs. Each has a single function with the exception
of the zoom knob which has in some cases a function other than zoom. With the upper-left
rotary knob the volume can be adjusted. The upper-right rotary switch is the mode selector
(it changes the mode of the operation). At the lower-right is the up/down knob which is
used for selecting sub-pages, sub-menus and editing menus. At the lower-left is the zoom
knob which is multifunctional. While its main function is to change the zoom level within
graphic mode, it can also be used if an error is made during editing –it is possible to move
the cursor back by rotating this knob. However, this can only be done if 'editing' is active
which is indicated by the cursor blinking.

4.2 Switching on the Unit
After a short press of the power-on button the main display and vario units will turn on and
a welcome screen will appear. The first screen shows the boot loader screen followed by
the Linux kernel screen and then the file system screen.
The boot procedure normally takes up to 20 seconds but in the case of a firmware update or
system check it can take longer. The final boot screen displays information about the
system firmware and the IGC serial number. When the boot procedure is completed the
profile selection dialogue is shown. Please refer to Section 6.2 for more details about
starting up the system.
4.3 User Input
The main display unit user interface consists of many dialogues which have different input
controls. They are designed to make input of names, parameters, etc. as easy as possible.
Input controls can be summarized as:
•Text editor
•Masked text editor
•Spin controls
•Selection control
•Checkboxes
•Colour selector
•Line width selector
To move the function from one control to another, rotate the PAGE selector knob (page
selector) as follows:
•Clockwise rotation will select the next control.
•Counter-clockwise rotation will select the previous control. Press the SELECT button
(usually lower-right) to enter control input.

4.3.1 Text Edit Control
The Text Editor is used to input an alphanumeric string of arbitrary length; the picture below
shows typical options when editing text. Use the bottom-right knob to change the value at
the current cursor position.
Press the CHAR>> button to advance the cursor to the next position. The cursor can also
be moved to next position using the bottom-left knob. Rotate it clockwise to move forward.
The Abc button is a toggle button and will change the letter case. Press it to toggle modes.
•Abc mode will start every new word with a capital letter; subsequent letters will be
lower case.
