1 System description
The system consists of minimum two units one of them is gliding computer and another unit is a 57 mm
vario. As an option is available also 80 mm vario unit. Gliding computer has a sunshine readable 5.5 inch
colour display and a high power Linux running computing device. Vario unit is a stand alone unit which
electronics is based on high precision digital sensor transducers. Connection between vario and computer
unit is via LX system bus. System extensions (second seat unit, remote control, compass ….) are also
possible after using of LX system bus solution. All connections are plug and play that means no exacting
works which needs specialists.
The manual for LX Zeus and for LX Zeus 4.3 is the same as the units uses the same software. Hardware
is also nearly the same.
LX Zeus 4.3 highlights:
• layout: 82x103 mm
• graphic colour display (400x800 pixels)
• the same operation philosophy as LX Zeus
1.1 Hardware concept
The system is designed to offer flexible solutions of system configurations, so the pilot is able to provide
some kind of custom design. At the back side of the unit there are plenty of connectors which makes
possible to connect (plug and play) a bright palette of GPS signal sources, as the unit doesn’t have
integral GPS receiver. Units as Colibri, LX 20, VL and any other GPS source which is capable to deliver
NMEA at nearly any baud rate, are compatible.
A special plug is provided for Colibri II connection in that case is Colibri II also powered from Zeus. Using
of Colibri II offers some important benefits for the pilot. The benefits are:
• automatic switch on of Colibri II as Zeus becomes power
• automatic power off after Zeus will be switched off and the system isn’t in flying mode, if flight
status is detected Colibri II will go on with its own battery
• downloading of flights via Zeus USB stick
When two GPS sources are connected at the same time, both signals are combined and loosing one of
GPS source will not degrade system availability.
Colibri II is used as an IGC flight recorder in case of an IGC approved solution. In that case a high level of
communication is established between Colibri II and Zeus and the pilot is able to operate the system, the
same way as by integral Flight recorder.
The unit can operate in portrait and also in landscape orientation. Conversion from portrait and vice
versa is simple and could be done by pilot.
Note!
Pictures used in this manual may slightly
differ from the LX Zeus original screens.

2.1.4 Vario settings
Settings of this menu defines vario characteristics
and some other important inputs connected to
vario and speed command.
Vario:
-vario filter defines dynamic of vario needle
lover number means faster reaction and vice versa
-smart vario*
-vario average time (display on vario unit)
-vario scale, three options (2.5, 5 and 10 m/s)
(5, 10 and 20 kts, if defined in Units)
Other:
-Silence range, defines no audio area around zero
by speed command,
-SC switching threshold, changeover speed
which will change from Vario to SC in case of
Auto setting
-ETA (Estimate Time of Arrival) calculation, you can
choose between several options
-Automatic SC switching, defines way of automatic
change over to SC
-External switch mode**, determinates external SC
switch status which change over to SC
TE value***, set TE compensation style, 0%
for tube compensation
TE filter*** only valid by electronic TE compensation
*
The LX system incorporates two configurable electronic filters in the circuitry. The first filter adjusts the
time constant and is adjustable between 0.5 and 5 seconds. The 0.5 setting is the fastest while the 5
setting provides maximum damping.
The second filter, called the Smart Vario, is a dynamic filter and controls the rate at which the vario
indication moves. When set to OFF, there is no restriction on the rate of movement of the vario indication
other than the setting of the time constant filter. When set to 1, the vario indication will not move faster
than 1 m/s (2 kts) per second, while when set to 4, the vario indication will not move faster than 4 m/s
(8kts) per second. It should be noted that when set to 4, the vario indication will move four times faster
than when set to 1.
Summary:
The Smart Vario should not be used in isolation but in conjunction with the setting of the time constant
filter. When the Smart Vario is activated, the time constant filter may need further adjustment to
provide optimum indications.

LX Zeus has a connection for an external speed command switch, which is wired to vario unit. Using
an external switch it is possible to switch between SC and Vario manually. Setting the SC Switch to ON
means that closing of the switch will cause SC mode, and setting SC INPUT to OFF means that closing
the switch will select Vario mode. There is a third option by setting SC INPUT to Toggle and connecting
a push button, now each press will toggle between SC and Vario (obligatory setting when using the LX

LX Zeus has the capability to offer variometer total energy compensation in two
ways. Selection of compensation method is done after selection of the % figure.
000% means total energy compensation when using a TE tube. When using this
solution the unit does not process compensation this depends entirely
on the TE tube and its installation. After an input of a percentage which is other than zerothe special
software routines will be activated and will provide an electronic
compensation process. The default value is 100% but this can be varied following
a test flight.
The TE compensation can be fine tuned during flight with the following procedure. It is essential that this
is only done in smooth air; it is not possible to tune the TE accurately when it is thermic.
• select 100 % and default TEF
• accelerate up to approximately 160 km/h (75 kts) and keep the speed stable for a few seconds
• gently reduce the speed to 80 km/h (45 kts)
Observe the vario indicator during the manoeuvre. At 160 km/h (75 Knots) the vario will indicate about –2
m/s
(-4kts). During the speed reduction the vario should move towards zero and should never exceed zero
(slightly positive indications are acceptable). If the vario shows a climb, then the compensation is too low,
increase the TE%; and vice versa. Repeat this procedure and make further adjustments if necessary.
Note!
Electronic and pneumatic TE compensation requires
different connection of tubes.

The TEF (TE filter) is the compensation delay. Larger numbers will increase the delay and vice versa.
During the first test is recommended to use TEF 4.
Electronic TE is only effective when the pitot and static sources are co-located and the pneumatic lines to
the instrument are approximately the same length. The best sensor to use is the combined pitot/static
Prandtl tube. If problems are experienced with the electronic TE compensation, then the most likely cause
is the glider's static source. The static source can be checked by plumbing the pneumatic tubes for
electronic compensation and then setting the TE: to 0%. In still air, accelerate to approximately 160 km/h
(75 Knots) and reduce the speed. Observe the vario indicator. If the static source is good, then the vario
should immediately start to move to show a climb. If the needle initially shows increased sink and then
moves to a climb, the static source of the glider is unsuitable and there is no way to provide successful TE
compensation electronically. The use of a dedicated and accurate fin mounted pitot/static source such as
a Prandtl tube might help.
There are two ways by which the vario units can be corrected for total energy; electronic TE
compensation based on speed changes with time; and pneumatic compensation with a TE probe. When
using pneumatic compensation by use of a TE probe. The quality of the TE compensation depends
entirely on the location, size and dimension of the TE tube. The installation must be leak-proof.
Note!
If electronic TE compensation is selected, then the TE(Pst) port should be connected to a good static
pressure source. If pneumatic compensation is selected, then the TE(Pst) port should be connected to
the TE probe.

2.1.5 Indicators
Indicator means vario indicator with its mechanical
needle and colour graphic display. One indicator is
incorporated into USB D 60 vario unit.
The system is also capable to drive secondary indicators.Secondary indicators may be simple repeaters
or may also indicate different data sets, all depends on indicator address.
Vario unit is always addressed as Number 1, secondary indicators
can be addressed from 1 up to four.
In general every indicator consists of: mechanical needle, SC dot, needle status indicator, upper and
lower digital indicator. It is important to point out that the settings should be done separately for vario and
SC mode of operation.
A radial moving dot serves as a continuous speed to fly indicator, no setting is possible.
Some explanations of terms:
Vario needle : means needle function in vario mode, alternatives; vario, Netto*, SC, Relativ**
SC needle: means needle function in SC mode……..
Vario up nr.: upper numerical display indication in vario mode
SC low nr.: lower numerical display in SC mode

Secondary indicators should be connected via 485 system bus.
There are three 9P connectors at the back of the unit
All contacts are absolutely parallel, so it doesn’t matter which one
is occupied. The unit can be also used as 485 system bus
splitter. To define Ind number use DIP switches which you find at
the back of the unit.
After indicator functions have been defined, switch the unit off and then on again, this procedure will
memorize the settings.

turn points which are included in turn point files. The turn point files (.cup) should be uploaded by USB
stick. See Setup Transfer for details. Practically unlimited number of .cup files can be uploaded. Turn
points can have different attributes and therefore also symbols which represent turn points are different.
Turn point TP as grass airfield
Turn point mode has also three pages, which can
be selected by SUBP key.
3.4.1 Creation of User Turn points
User turn points are turn points which are created
by pilot after using commands of LX Zeus. Such a

3.5 Task Mode
Task is a complex process which guides the pilot around the turn points of the task. Each task consists of
turn points, start point and the finish point. Additionally take off and landing can be input, but those points
don’t have any influence on task execution.
3.5.1 Task organisation
Zeus has a store for 101 tasks. 50 tasks can be
imported in one .cup file and such tasks are called
imported (IMP), next 50 can be created by user in
LX Zeus (by hand) and those tasks are called User (USR).
One task is called DECLARED. This task will be written
after a Declare process will be executed in TSK Menu.
3.5.1.1 Task declaration
LX Zeus uses external flight recorder and in case of Colibri II as a part of the system a flight declaration
transfer from LX Zeus into Colibri II is managed. All what the pilot has to do is to execute declare
procedure in TSK menu. The actual task data from Zeus will be automatically transferred to Colibri II.

Creation of Zones
ZONE function makes possible to create any
known geometry for turn points, start and finish.
The creation consists of input of sector angles
radius and orientation.
Auto next input defines change over philosophy
over turn point. AUTO means automatic change
over immediatelly after sector will be reached.
This function is default active as sector radius
is below 10 km. Bigger sectors offer a not automatic
change over. If Auto next no is active, MOVE function
will become active and that makes possible
to modify the task distance even before flight.
Exsamples of typical zone geometries.
3.5.4 Task Start, Restart and Next TP
Thre are two methodes of starting a task. Manual
start is posible after using of Next TP function. Next TP
command will change over to next TP every time when
activated, doesn’t matter if the glider is in the sector
or not.
A more sophistic start method is automatic solution.
In that case the pilot should ARM automatic start.
Use ARM command which is offred after press on
TSK button. Activation of ARM and also deactivation
are clearly shown on the display. Disarmed means
canceleratin of ARM status.

-R1below 10 km Auto next active (automatic change over)
-R1 above 10 km manual change over necessary
3.5.5 MOVE Function (during flight)
When flying an AAT big sectors are set and therefore
the pilot has to decide where to turn to next point.
Function Move helps the pilot to find optimal solution.
After long pres on TSK / MOVE button so called
move function will become active.
Use Zoom and Vol knobs to move the turn point.
All task relevant data which are affected by move
are shown at the bottom part of the display.

4 Airspace Management
The airspace used in LX Zeus can be managed by pilot to achieve optimal relation between loading of the
display and readability of the display. Too much information will reduce display readability significant.
4.1 Basic airspace settings
Those settings are available in Airspace section of
User Setup.
4.1.1 Hide airspace above
The airspace sections which are much higher than actual
glider position are not so important, but if disabled will
reduce information density of the display significant.
Use Hide airspace above to define altitude margin which
you need for a still safe flight.
4.1.2 Define appearance of airspaces regarding to zoom
After using of Show on zoom function you can define
By which zoom the airspace will become visible on the display.
Two extreme situations are described with always and never.
Factory setting is always.
4.1.2.1 Warnings
If set disabled (⌧) the airspace warnings will not appear at all,
setting checked () will produce airspace warning information.
Warning box is an indicator of the display, so the pilot is able
tp move the box and also to customize colours.
Airspace warning information consists of Airspace name, horizontal and vertical distance and is as default
positioned in the upper section of the display. The nearest point to enter
the airspace becomes visible on the display as a numbered dot.
Number 1 means more critical situation than number 2.
As long as the warning isn’t critical the dot and also
the text will be yellow.

4.1.3 Disabling of airspace sections
After using of Near function is possible to disable
individual airspace sections. The action may temporary
disable one or more zones or disable zones of interest for ever.
5 GPS signal management
LX Zeus has two inputs for GPS signal which
are available on the back of the unit.
both solutions are realized by 6P telephone
type connectors which are marked as:
• Colibri II
• Flarm
5.1 Colibri II plug
Colibri II plug can be used exclusively to connect
Colibri II units. The plug delivers also power (5V)
for Colibri and receives its data directly without
any data interface. The communication way is bidirectional.
Every unit equipped with Colibri II comes with suitable
connection cable (USB mini/ 6P telephone).
5.2 Flarm plug
Flarm marked input makes possible to realize
a plug and play solution to connect any unit which has
an IGC standard compatible connector. Port delivers
also 12V.
Following units can be connected plug and play:
• Colibri, LX 20 – 2000, VL, LX Flarm RB, LX Flarm MB, Flarm
5.3 GPS signal for navigation
Both GPS input connectors are wired to LX Zeus microcontroller module which prepares an integral GPS
signal for the main computer. So, the computer will be supplied with valid GPS signal as long as one GPS
receiver delivers valid data. Colibri II data have priority, to guaranty that navigation data will match flight
recorder data. A symbol which is positioned in the right upper corner of the display shows GPS signal
status:
• red GPS BAD
• green GPS OK
• white symbol with ⌧ means
no GPS data present
Note!
LX Zeus is able to adapt baud rate
to any value between 4800 and
38400 automatically, so baud rate
of GPS source connected to
Flarm input doesn’t matter.
LX Zeus

5.4 Colibri II Zeus interaction
Colibri II will switch ON automatically when power from Zeus will be applied. In case that Zeus will go off
during flight, Colibri will remain ON using its own internal battrey. In normal situation which means that
Zeus will be switched OFF on ground after landing, Colibri II will go OFF automatically after no flying
condition will be detected (this takes some minutes). Described philosophy prevents that Colibri will
remain on after landing by pilot mistake. The solution makes possible to install Colibri II inside of the panel
or in baggage department, where no visual and physical contact is possible.
5.4.1
Colibri II - Zeus data exchange
Colibri II and Zeus build together a vario navigation system with high level approved flight recorder. The
units exchange following data:
• LX zeus receives GPS data from Colibri II (automatic baud rate adjustment, no assistance
necessary)
• after action on Zeus the actual LX Zeus task can be declared to Colibri II (DECLARE in TSK
menu)
• flight recorder settings can be set after using of Logger section of Setup
• automatic transfer of Colibri II flights into LX Zeus
• downloading of flights via USB stick
See also section 8.1.
5.5 LX Zeus and Flarm
Flarm should be connected to FLARM marked plug of LX Zeus. Flarm will also receive power via that
plug. If Flarm is also connected to aircraft power network via its power input wires, doesn’t happen a short
as there is a diode built in. This separates both power supplies. Up to two Flarm external displays can be
connected to the plugs marked as Falrm external display. SD card slot on LX Zeus front is directly
connected to Flarm SD interface (valid for RB ), without Zeus interaction. The SD card may be used for:
• Flarm firmware update
• downloading of flights stored in Flarm
• uploading of declaration (via .cfg file stored on SD)
On the back side of LX Zeus there is enough space
to install LX RB as an integral part of the system.
All connections are plug_and_play.
Non integral solutions can also used.
5.5.1 Visualisation of Flarm objects
Flarm objects are visualised in two different ways.
First one becomes active after activation of so called
Flarm radar screen (long press on FLARM).
Flarm objects are also visible in all three graphic
navigation pages.
LX Zeus

5.5.2 Flarm external displays
LX Zeus HW makes possible to connect
maximal 2 Flarm external displays, both
plugs are driven from Flarm directly without
any Zeus influence.
LX Zeus

6 Remote control
LX Zeus can be also operated by remote
control stick. The stick is standard LX Navigation
product which differs from sticks used by
LX 7000/7007 series only in labelling.
Therefore is upgrade of existing stick very easy.
Remote stick should be connected to one
485 plug, no special initialization is necessary.
6.1 Remote in second seat
Remote stick for second seat is the same as for the first seat (no different firmware as by LX 7000/7007).
The unit should be connected to second seat unit 485 bus.
7 Second seat unit
Second seat device is connected to the master
unit via CAN bus, the connection includes also
power for second seat. This means that second
seat unit doesn’t need power supply. An external
toggle switch makes possible to switch off the unit
during single pilot operation period. Otherwise
all commands are the same as by main unit.
GPS inputs are inoperative, so there is no sense
to connect GPS sources to that plugs, the same
is valid for Flarm display plugs.
LX Zeus 4.3 can be also used as a repeater in case
panel space problems.
7.1 Connection of Vario and Remote
Vario indicator (not USB D unit) should be
connected to 485 bus of second seat device
(this is not the same as by LX 700077007).
The same is valid for remote. Both vario
indicators and remotes are compatible with
existing units connected to LX 7000/7007.
Remote doesn’t require any setup.
7.1.1 Secondary Vario setup
Function of vario indicator connected to
second seat unit, should be defined in
Setup of second seat unit.

7.2 Interaction LX Zeus – LX Zeus Second seat
8 Flying with LX Zeus
It is recommended to prepare the unit for every flight before take off to ensure a stresses and contentedly
flight. This is especially important before any contest, record or badge flight.
8.1 Flight preparation on ground
It is suggested to check following:
• data base status
• prepare task (use new or edit options, or select from task store)
8.1.1 Before take off
• switch the unit ON at least 3 minutes before take off (this will ensure sufficient GPS reception
and will create a base line of baro trace)
• select correct pilot (many setting belongs to pilot)
• check task if correct after using of Task edit
• if declaration is obligatory, provide declaration
• switch on second seat unit in case of double seated glider
8.1.1.1
QNH setting
A long press on 1-4 button will open QNH input dialogue.
The pilot should input actual QNH value of the airport
where he will take off. This action should be carried out
on ground, after take off the menu will not open any more.
After input of QNH on ground the pilot will be able to adjust
altitude during flight, if QNH will change.
8.1.1.2
Task declaration process
Task declaration means inscription of task relevant data into IGC approved flight recorder. As LX Zeus
uses external units as flight recorders (Colibri II and Flarm IGC), the declaration data should be sent
towards flight recorder from Zeus. A simple DECLARE procedure executed from Zeus TSK page will
ensure task data transfer.
Declare command is available after pres on Zoom
in TSK mode. After activation the task declaration data
will be inscripted into Colibri II and also Flarm, if
Flarm unit is an IGC version.
8.2 During flight
The Zeus HW and SW concept is so far optimized that pilot doesn’t spend too much time to operate the
unit during flight. It is important to point out that there are many short cuts which enable direct and fast
access to most important functions. The pilot isn’t obliged to terminate edit process until end due to Auto
close feature, which closes the process after some seconds of no active commands.
Note!
Declaration process termination is visualized
Note!
QNH setting doesn’t replace setting of elevation during
booting, this should be carried out under any
conditions. QNH setting isn’t obligatory and may be
over jumped .

Note!
By not started task the statistics data is limited
to take off and flight duration.
8.2.1
After take off
A very significant signal that the unit has changed to flying
mode is Log Book replacement with statistics page after
pressing on STAT button.
8.2.1.1 Statistics
As mentioned in previous chapter the statistics page
will open after press on STAT button.
Statistics page offers following statistics data:
• Thermal analysis (not active at the moment)
• OLC; calculation of OLC points (not active at the moment)
• Baro; shows baro trace from take off until present position
• Task; presents task statistics data distributed by legs
The statistics page colour structure can be adapted under
the pilot personal requirements after using of;
Setup/User Interface/Statistics colours
8.2.1.2 Event function activation
This function is active only if Colibri II is a part of the system. A long press on EVENT button will send a
command to Colibri II flight recorder to activate so called event function; that is in fact recording in shorter
intervals as default for a limited time. The conditions are to be set in Setup/Logger.
8.2.1.3
Marker setting
If the pilot wants to mark appointed position
(outlanding place, thermal….) this can easily be done
after activation of Marker function. The process is very
fast and doesn’t occupy pilot. To mark a position pilot
should do as follows; press Zoom and Add marker
Marker is visualized as a yellow triangle positioned
over graphic page. Only one marker can be active at
the same time. To set a new one simple repeat the
procedure. Marker will be stored as user turn point
designated as #MARKER. If edit function has been
used #MARKER can be converted into normal TP.
#MARKER can be also deleted after using Delete TP command. In case of navigation data necessity
towards #MARKER point, simple select #MARKER after using of Select TP command.
Note!
If task consists of more than three legs, use
zoom to select legs of interest.

8.2.1.4 Task Start
Task start is a quite complex procedure, especially by high density of gliders who intend to start at nearly
the same time.
As pilot intends to perform task start in a close proximity
A very simple operation should be carried out;
-press on TSK button and after to ARM
A very significant message ARM will appear on the display.
This message will remain until first line crossing, after first
line crossing the task will start automatically without pilot
assistance. Task start is accompanied with a very significant
message:
In case that the pilot forgot to ARM start and has crossed the line, execution of NEXT TP will solve the
problem.
8.2.1.5 Task Restart
After a bad start and intention to provide a new start, the pilot
is obliged to execute so called Restart function. After press on
TSK button you will find RESTART option. After restart the task
will be reset (doesn’t matter on which leg) and a new start
could happen.
8.2.1.6 Task Finish
Task finish will be detected after the glider will finish the finish line. The situation will be accompanied with
a very clear message.
8.2.1.7 Flying AAT
AAT (Assigned Area Task) is a modern manner of task flying on competitions. The basic idea is to set
relative big sectors over turn points and this makes possible that the pilot decides how deep into the
sector will be entered. Usually a time limit is set which prevents to short tasks.
• set time limit: use Task/Edit
• set sector geometry: use Task/Edit/Zone
• over turn point: change to next turn point is exclusively executable after using of NEXT TP
command.
• move function: makes possible to adapt AAT distance
and also get informed about important task parameters
as for instance: remaining distance, required speed….
Move function is available after long press on TSK/MOVE
button. Use zoom and volume rotary switches.
Note!
ARM command can be
executed at any time,
even on ground.
Note!
After RESTART, the unit will
change immediately into ARM
status.
Note!
If sector radius is bigger than 10km,
the unit will recognise this as an AAT
and will set manual change over to
next turn point. Using smaller sectors
by AAT requests manual setting of
No Auto next.
Note!
If task time will not be set,
many statistics data will lack,
for instance: task delta time,
task remaining time….

8.2.1.8
Final glide calculation
The final glide calculation is based on following inputs:
• actual MC setting
• wind
• polar
• bugs
• ballast
• safety altitude (reserve)
The final glide is indicated in graphic page. As the final
glide box has nature of a display indicator, so this can be
moved over the display and also custom colours could be
assigned. (–) figures means below and (+) above final glide,
both in meters resp. in ft.
The final glide situation is also present in the first navigation
Sub page of all three navigation modes. In case of flying
a task, final glide profile until finish will be displayed.

8.3 After landing
It is recommended to keep the instrument ON for a few minutes
after landing; this will ensure base line of baro trace. Simple wait
until a very significant message on the display will appear;
This shows that flight recorder is terminating the flight and data security
operation is in progress. After calculation of security, statistics page will
be replaced with Log book and the unit is now ready to be switched OFF,
or flight download process can start.
8.3.1 Downloading of flights
LX Zeus can full interact with Colibri II in case that Colibri is used as a flight recorder. That means that
downloading of in fact Colibri flights is possible after operation on LX Zeus. The flights will be finally stored
on USB stick. After no connection to Colibri II the unit (Zeus) will produce its own “flights”, which are not
IGC conform. The structure meets IGC standard and therefore such flights could be evaluated by any
program which accepts .IGC data format.
In case of Flarm (RB IGC version) connected to LX Zeus, its flights will be stored to Flarm SD card,
without any Zeus interaction.
8.3.1.1 Downloading Colibri II flights
After termination of the process described in 8.3.1 downloading of flights can start. Downloading of flights
stored in Colibri II is possible exclusively after using of USB stick. The procedure:
• insert USB stick
• press STAT button (log book will open)
• select flight of interest
• execute Save to USB command
The process will take a couple of seconds
a very significant message will show termination
The flight is now available on USB stick in sub folder Flights. Flight data are stored in .IGC format and
therefore immediately ready for evaluation.
8.3.1.2 Downloading of flights recorded by Zeus
If Zeus will not recognize Colibri II as a GPS source
will start its own recording. The procedure is the same
as described in 8.3.1.1. Flights produced by Zeus are
designated with .

8.3.1.3
Downloading of flights stored in Flarm
If an IGC approved Flarm Red Box unit is connected to LX Zeus a direct flight downloading via SD card
slot which is positioned on the front panel of LX Zeus is possible. The SD card slot is wired directly to
Flarm without any Zeus assistance. General rule by Flarm is that flight will be stored to SD card after next
power on of Flarm. So, power LX Zeus off and new on to download the flight.
8.3.2
Colibri II power ON and OFF management
Colibri II will switch ON immediately after Zeus will receive power and will not switch immediately OFF
after Zeus will loose power. Colibri II will switch OFF automatically after the unit will recognize not flying
condition for about 15 minutes. Close before switching off, some audio alarms will be expressed.
Note!
Pilot doesn’t need to take care about Colibri II switching OFF, as Colibri II to will switch OFF
automatically after no flying status will be detected.

9 Installation
9.1 Mechanical installation
As the unit dimensions doesn’t match air norm standard, a new cut out in the panel should be made.
There are two ways how to prepare the panel. First one is buying of a new panel and second solution is
upgrade of existing panel. Upgrade can be done also by user; in that case some little experience in glass
fibber technology would help. Instructions how to rebuild the panel you can obtain by LX Navigation.
Every unit comes also with an iron template which makes possible to manufacture LX Zeus cut out by
hand. In case of CNC solution, please ask for .dwg file.
Reinstallation after panel upgrade
9.1.1 Installation of Vario unit
The unit occupies one 57 mm standard cut out. The maximal dimensions of the unit are 60x60 mm and
don’t exceed dimensions of classic pneumatic instruments. In case of space problems, the unit can be
separated into two parts which are connected via cable.
In case of panel space problems the vario unit can be spitted into two parts connected via cable.
9.2 Electrical installation
This part of installation is easy and doesn’t need any specialists. The system receives its power via two
power lines which should be connected to 12V glider power source and ground. Red wire is 12V and blue
wire is Ground.
A 2 pole plastic connector which is positioned approximately 20 cm from the unit casing ensures simple
disassembling of the unit in case of repair.
9.2.1
Installation of USB D 60 (vario unit)
USB D 60 unit comes with prefabricated cable set, which has two connectors. 15 pole type should be
inserted into vario unit and arrested with appropriate springs.
The 9P connector should be inserted into any free 485 marked plug on Zeus back. The unit receives also
its power from Zeus.
Important!
There is no fuse built in the system, obligatory use 3A external fuse. Never remove Terminator
which occupied one CAN port (factory preset). Terminator should be removed in case of second
seat configuration. In that case the terminator should be positioned on second seat unit.
Note!
Respect labels near pneumatic connectors, during pneumatic tube connection process. See also
3.1.4 for details.

9.3 Installation of second seat units
The second seat unit is the same size as master, so no difference by mechanical installation works.
9.3.1 Electrical installation
The second set unit doesn’t need external power, as it becomes power via system bus (CAN). For CAN
connection two 8P connectors are provided on master and also on repeater. The interconnection of both
units is extremely simple and easy, all what is necessary is to insert CAN marked cable in one of two CAN
marked plugs. The same is valid for first and for second seat.
Second sat unit comes with two red wires which are terminated with a toggle switch. It is recommended to
install the switch somewhere in the rear panel, as this will make possible to switch off second sat unit
during single pilot operation.
Note!
All interfaces as; remote control, vario indicators…… which interact with second seat, should also
be connected to second seat 485 bus.
Note!
Newer remove CAN
terminator which occupies
one CAN plug of second
seat unit.

11 Zeus 4.3 specific
The units differ in general very little. The most important fact is that both units use the same SW package
and that means that all new functions will be automatically implemented also in 4.3 version. It is important
to point out that LX Zeus 4.3 uses a high resolution display which compensate smaller layout significant.
Due to 100% compatibility with 5.5 inch variant, a mixed use in double seated gliders is possible.
The main differences are as follows:
• display size
• display resolution
• layout
• slightly different push button organisation (2x4)
• no display backlight intensity adjustment
