The external display has two modes of operation:
•
WARNING Mode will activate a red blinking diode, if another glider equipped with Flarm will
be close and a prediction for a collision risk will exist. An audio warning will be also executed.
Higher collision risk will increase blinking frequency and the same is with audio. The warnings
are classified into three levels (See Flarm manual for details)
-First level approximately 18 seconds before predicted collision
-Second level approximately 13 seconds before predicted collision
-Third level approximately 8 seconds before predicted collision
•
NEAREST Mode will show the direction to the nearest glider which position is inside of radio
range. One green LED will light permanently and there will be no audio. The unit will change
over to Warning Mode automatically, if warning criteria will be fulfilled and will continue in
NEAREST after collision risk will disappear.
Note!
The external displays produced by LX Navigation will change over to Demo mode after MODE button
will be pressed short 10 times. Nearest mode and all possible warnings will be displayed. To change over
back to normal operation switch the unit off.
•
Pressing of MODE selector continuously for approximately 4 seconds will deactivate Flarm
external display for 5 minutes, no warnings and no near information will be displayed during this
period. A very typical situation only Power LED on, will characterize this status.
Note!
To change mode of operation press MODE button for approximately 2 seconds. If the radial LED’s will
run from top toward bottom means change over to NEAREST and vice versa. After new power on, the
mode active before switching off will remain.
•
Obstacles. Flarm electronic is capable to store coordinates of obstacles, which could cause a
collision during flight. This data is available on www.flarm.com, use Flarm tools to update. The
unit is factory loaded with actual obstacle database. An obstacle warning will be activated, if an
obstacle is to be found in the front of the glider and a collision risk is predicted.
After a low level warning has been activated two upper LEDs will be active (such a situation will
newer appear by glider collision risk). Medium and high risk will be indicated with more LED’s
active and more frequent audio signal.
•
To change audio warning volume press short mode selector, each press will increase audio
volume (three levels and mute available).
Note!
To change mode of operation press MODE button for approximately 2 seconds. If the radial LED’s will
run from top toward bottom means change over to NEAREST and vice versa. After each new power on,
the unit will start in Nearest mode.

3.1.1 Display settings
Using of mode selector button is possible to adjust some parameters of the display (baudrate and
hierarchy). Disconnect the unit, press mode selector and hold, power on and continue holding of mode
selector for about 4 seconds.
The display parameter indication will change (see table below) after each press on mode selector for
approximately 2 seconds. To change press mode short, the status will indicate circular LED’s.

Table of possible settings
If two units will work in parallel (double seater), one unit must be PIC (front seat) and another PAX.
Note!
LX Flarm Mini Box baudrate is factory set to 19200.
3.1.2 Mini Box settings
As there are practically two units built in the Flarm Mini Box, (Flarm electronics and the display) it is
obligatory that both have the same communication speed (baudrate). If there is any reason for another com
speed, (using of Flarm as GPS source for other units…), the com speed of the Flarm unit can be adjusted
any time after using of Flarm tools. Use option Settings, how to connect Flarm Mini Box to PC see capture
4.
Note!
The option “Navigation and Flarm” means that the Flarm unit is sending Flarm and navigation data. This
option is obligatory to be enabled, if the LX Flarm Mini Box will be taken as GPS source for another
navigation instrument or PDA.

If another navigation device for instance PDA is intended to be used, a splitter should be inserted. LX
Navigation offers a wide range of splitters.
Note!
LX Flarm Mini Box settings update is also possible to be carried out by using of SD card and flarmcfg.txt
file. See capture 8 for details.
4 Firmware update
Flarm software expires and therefore periodically firmware upgrades are necessary. Flarm original tools
should be used, available on www.flarm.com. A cable set isn’t a part of delivery. Use IGC compatible
cables, for instance Colibri/LX20 power and data adapter (COL-AC-PC).
Note!
Colibri power adapter will also power Mini Box
The procedure:
• Run actual Flarm tool on PC
• Power ON Red Box
• Wait (apr.30 seconds) until connect status on tools will appear

5 Installation
The unit is designed to be installed on the top of the instrument panel to ensure GPS reception. As the unit
needs some manipulation during flight, please respect this fact.
5.1 Power
Each unit is delivered with a power cable. On one end you will find one red and one blue wire, connect
them to the glider 12 V power network (red +/ blue -). The opposite side is equipped with a 6p telephone
type connector and this should be plugged into suitable plug on the back side of the unit.
Note!
There is no internal fuse built in the unit. Use External fuse 1A. The unit is prevented against wrong
polarity of input voltage.
5.2 RF antenna installation
The RF antenna installation should be taken serious; a bad positioned antenna may reduce system
parameters dramatically. The antenna orientation should be as much as possible vertical and also as high as
possible. Special care should be taken by carbon gliders.
Dipole antenna
5.3 GPS antenna orientation
The GPS antenna is positioned on the top of the unit and can’t be removed. Don’t cover antenna with metal
parts to ensure GPS reception.
Note!
Flarm unit will not work until having GPS 3D, means antenna installation is an important fact.

6.1 Firmware update procedure
Ready for update:
-Insert the card and switch the Flarm unit off, for minimum 5 seconds
-Power on Flarm unit Firmware update:
-An update will follow after a file having extension .fw will be detected; the procedure will take
approximately one minute and will run automatically.
The obstacle data base update procedure:
-If an .obs file type will be detected, an update will follow. The update may take several minutes.
Read of flight recorder data:
-The last 20 flights will be automatically copied to SD card after each power on. If some flights also exist,
they will not be doubled. After a longer time flying without the card inserted the copy procedure may take
some longer time because all 20 flights must be transferred to the card. To start copy to SD card remove
power for apr. 5 seconds and power on again. The procedure will run automatically.
7 Limitations
Note!
Using of Flarm will not reduce responsibility of the pilot to monitor the airspace and to react in case of a
collision risk.
See Flarm manual for details.
8 LX Flarm Mini box with IGC approved flight recorder
LX Flarm Mini Box is offered also with “diamond level” IGC approved flight recorder. Units having this
option differ against to non approved units in following:
• On the label you see a three character IGC designation code (for instance MR0)
• The unit is protected with two safety label against non authorized opening of the box
• A push button marked as event is positioned on the top of the box, its main function is setting of
additionally records after activation
Note!
The label should remain not damaged, after damage the flight data will become invalid.

8.1 Task declaration
There are many ways to provide task declaration. The simplest way seems to be with SD card and
flarmcfg.txt file. Immediately after Flarm will recognise mentioned file an automatic update will follow.
To create files use FLARM-CONFIGURATION TOOL available on www.segelflugsoftware.de/flarmcfg/.
As a possible PC solution we suggest SeeYou and as PDA solution you can use:
• ConnectMe ( a free ware program from Naviter)
• Srepla
