4System Description
4.1 Description of larm Led Display
Flarm led consist of 5 main parts:
•Status LEDs
•Horizontal direction LEDs
•Vertical direction LEDs
•Push button
•Beeper
4.1.1 Status LEDs
Status LEDs indicates if flarm receiver receives any data, transmits data and GPS status.
GPS status led has 3 different modes:
•Fast blinking mode, means, that FlarmLed does not receive anything over serial bus
(probably needs to set correct baud rate)
•Slow blinking means, that GPS status is BAD
•Solid light means, that GPS status is OK.
4.1.2 Horizontal direction LEDs
12 horizontal LEDs are indicating the direction of threat.
4.1.3 Vertical direction LEDs
5 LEDs are describing vertical angle of threat divided by 14°
4.1.4 Push Button
With push button we can adjust volume of beep, turning on/off near mode or adjust initial
settings of FlarmLed display.

4.2 Normal operation
In normal operation with short press, we can cycle between three different volumes (Low,
Medium and High). With long press, is enabled or disabled near mode. Switching of mode is
also visually supported with moving light around circle. Red moving light means, that near
mode is enabled, yellow moving light means, that near mode is disabled.
4.2.1 WARNING Modus:
WARNING Mode will activate a red blinking diode, if another glider equipped with Flarm
will be close and a prediction for a collision risk is calculated. An audio warning will be also
executed. Higher collision risk will increase blinking frequency and audio beep rate. The
warnings are classified into three levels (See Flarm manual for details)
oFirst level approximately 18 seconds before predicted collision
oSecond level approximately 13 seconds before predicted collision
oThird level approximately 8 seconds before predicted collision
4.2.2 NEAREST Modus:
Will show the direction to the nearest glider, which´s position is inside of radio range. One
yellow 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.
4.2.3 Obstacle warning
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. The warning is shown with two red LEDs, symmetrical
around the 12 o´ clock LED at 1 and 2, they alternate with those at 11 and 1. As we
approach to the obstacle the frequency of the alternation increases.
4.2.4 Undirected PCAS warning
Is the FlarmLED connected to a device, which also translates transponder signals with ADS-B
data into Flarm warnings, you will receive them in the same logic as above. Transponder
signals without ADS-B data contain no direction for the thread therefore you will get an
undirected warning with the following alternating signals:

4.3 Powering up larmLed display
LXNAV FlarmLed is powered directly from flarm device with 3.3Volts. When gets power it
passes boot up sequence with test of all LEDs and short beep, shows version of FlarmLed
display firmware (yellow led indicated major version, red indicates minor version).
4.4 Setting up larmLed display
If we hold push button, during power on, LXNAV FlarmLed will go in setup mode, where is
possible to adjust following settings:
•Communication speed
•Master/Slave mode
•Enable7disable PCAS warnings
Yellow led indicates mode that we are setting, Red LEDs indicates setting of each mode.
Red 12 Red 1 Red 2 Red 3 Red 4 Red 5
Yellow 12 Baud rate 48 bps 96 bps 192 bps 384 bps 576 bps 1152 bps
Yellow 1 Master/Slave Master Slave / / / /
Yellow 2 PCAS Enabled Disabled
This setup is prepared because some FLARMs are set to different baud rates, so it’s
necessary also to set FlarmLed to same baud rate. Normally Flarm default baud rate is
192 bps, on that setting is also set FlarmLed display.
Master/Slave option is usable only if we have connected to flarm more than one Flarm led
display. In that case display can interfere each other. Only one can be set to Master, all
other must be set to slaves.
Last setting enables or disables PCAS warnings, which might be sometimes very annoying.
