2 Basics

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 are featuring also PDA port for easy connection on 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:

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.
Artificial horizon can be enabled on main display unit. Vario sensor box is constantly
using data from inertial platform in order to make vario signal smoother, however if pilot
would like to see artificial horizon and software option to do so must be purchased.

Page 12 of 192

Basics Version 6.03, May 2017

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 second seat
device or for side by side operation.

 Electrical Compass Device

4.1.3 Buttons

All buttons have a dynamic function; the first time one presses each button, it displays its
function 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 upper­left 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 shown by the cursor blinking.

Rotating the zoom selector changes colour transparency. Transparency is very important for
fill colours which are used for airspace zones, observation zones and FAI area. If a fill
colour is not transparent (0%), all other map items will not be seen through it. If a fill
colour is 100% only the solid border will be drawn.
Press PICK button to define colour more precisely. A colour dialog will open, where you can
select colour from HSV circle or enter values for red, green and blue colour.

4.3.9 Pull down menu

4.4 Switching off

Please use one of the following recommended methods for shutting down the LX90xx
system:

Method 1

Press the button with the OFF label which is displayed in navigational modes. See Chapter

5.5 for more details. A message to confirm shutdown will be shown.

Method 2

Press the button with the OFF symbol for approximately 4 seconds. The OFF message will
be displayed and the instrument will shut down. When the message appears you must
release the power button.

Page 26 of 192

System Description Version 6.03, May 2017

If you are using method 2 to switch off the system it is necessary to release the
button when you see the shutting down message. If you continue to press the off
button the main display unit may shut down by method 3.

It is important that the main display unit is switched off via software. Never
power down the system using the main power switch. The main display unit is
running the Linux operating system and sudden power loss may corrupt the file
system.

If main power is lost for a few seconds during flight the flight recorder will not
produce two flights. The most important flight parameter (altitude) will remain
which means that the final glide calculations are not affected.

Method 3

When the button with the OFF symbol is pressed for more than 8 seconds the system will
perform an unconditional shutdown. This method is recommended only in case that the
program hangs and it is not possible to shutdown with methods 1 or 2.

If the request for OFF is made during flight the instrument will ask for confirmation so that
the system cannot be switched off by mistake.
