PART ONE –Introduction
1.1 Preamble
Why LX Navigation?
LX Navigation is one of the oldest glider navigation brands. Its founders started experimenting with glider
computers way back in the '70-ies and the Company has been working on improving your flight
performance ever since.
Throughout the last 40 years or so it has been working on instruments that most pilots will have used at
some time. In fact our equipment can be found in almost any gliding club !
Our equipment has always been ground-breaking.
Our motto?
Be the first. Be the best. Be different.
Why Zeus?
Because Zeus is a top of the line product. Crème de la crème.
Used by pilots from all over the world, our instruments offer the best for both cross country soaring and
competitions. The LX Zeus is the latest in this tradition.
Devices
We offer a wide range of instruments suitable for both club and competition soaring.
Our systems combine two components:
First, a glider computer (LX Zeus) which is used for calculating and displaying all of the key information
used by pilots. This glider computer is the brain of the operation.
The second part of the system is a variometer (Eos, Helios, and Era). Its job is to gather the information
which the Zeus uses. The vario has pressure connections as well as the GPS antenna connection which is
required for IGC logs.
There is a wide variety of choice for varios and for LX Zeus display sizes.
All our varios are standalone devices which can be used without a glider computer for displaying basic
flight parameters such as final glide information, Speed Command (SC) as well as simple navigation. Our
varios also have an internal battery which means that your IGC logs do not depend on your glider`s
batteries.

System extensions (second seat unit, remote control (LX Joy), compass, NavBox, MOP, Flap sensor, AHRS
...) are also possible. Everything is connected using a CAN bus (single cable for power and data). All
connections are plug and play, which means no specialist is required to install the system.
1.2 Operation
Front panel interface
Communications between the pilot and the instrument is done via two rotary knobs and 8 push buttons.
All buttons and rotary switches have a double push function (short and long press). All buttons are
labelled which makes unit manipulation very easy. The top labels are selected with a short press.
Bottom labels are selected with a long press. On Zeus 2.8” and Zeus 4.3” there is a 4-4 button
arrangement. On other screen sizes the button arrangement is 5-3.
Both rotary knobs are multifunctional as follows:
Default functions:
 Volume rotary knob
o Volume adjustment function - scroll
o Select (TP, APT, TSK) - short press
o Shortcuts - long press
 Zoom rotary knob
o Zoom adjustment function –scroll
o Open more options (TP, APT, TSK) - short press
o Edit NavBoxes –long press
In edit:
 Volume rotary knob: bigger steps when selecting values and escape/cancel by pressing it
 Zoom rotary knob: scrolling and press confirmation
USB/SD
There are two ways of transferring files: either via USB or via SD port. A standard USB-A female port is
available on each device (on Zeus 2.8 slim USB keys should be used). The port is exclusively used for data
transfer and firmware updates. The micro SD port is only used when Flarm is connected (Flarm Red Box,
Swiss Flarm and optionally Flarm Mini Box). The micro SD port is used for direct communication with
Flarm, which means downloading flights stored on Flarm, uploading declaration and Flarm firmware
updates.
Back panel interface
On the back side of the unit there are the following connectors:
 2x CAN bus*
 2x User ports
 Flarm port (12 V power and data) *
 Flarm display output
 USB – A port

* CAN bus connects LX Zeus to:
 LX Eos (57/80)
 LX Era (57/80)
 Second seat unit
 LX Joy
 LX NavBox
 LX Flaps sensor
 LX MOP
 LX AHRS
1.3 Installation procedure (LX Zeus and Eos/Era)
Installation of LX Zeus
The dimensions of larger units (4.3, 5.5 and 7.0) do not match air norm standards (57 or 80mm). A new
cut out in the panel is necessary. There are two ways to prepare the panel:
The first option is to buy a new panel from the glider manufacturer and the second is to upgrade the
existing panel. The user can also do a panel upgrade and, in that case, basic experience in fiberglass
technology will help. (LX Navigation can provide additional instructions on how to rebuild the panel by
yourself –just ask!)
Every unit (except the 2.8 inch, which fits an 80mm instrument hole) is supplied with a carbon which makes
it possible to make the LX Zeus cut out by hand. If a CNC solution is planned, then please ask for .dwg file.
1.3.1 Installation of LX Eos/Era
The unit occupies one 57 mm or 80 mm standard cut-out. The maximum dimensions of LX Eos/Era 57 are
60x60 mm max and they do not exceed the dimensions of classic pneumatic instruments. LX Eos/Era 80
mm are 82x82 mm max. LX Eos/Era is shallow, which means that there shouldn’t be any problems
installing it as regards space behind the panel.
Note!
Check labels near pneumatic connections on LX Eos/Era, during pneumatic tube connection
process to ensure correct connection.

1.3.2 Screen rotation
The screen can be rotated by using password 9109 under Setup > Service > Admin password. The buttons
must be rotated by hand. Follow the procedure below:
1. Open the unit (remove all screws and cover)
2. Move rounded rubber to the middle
3. Take out the button and rotate it to the proper position
4. Put button back on blue button (be careful that blue button is inside the black hose)
5. Put rounded rubber back to the first position (be careful with the Rotary knobs as the rubber
must not be pushed all the way in)
1.3.3 Connecting LX Zeus with LX Eos/Era
This part of the installation is easy and doesn’t require any specialists. LX Zeus and LX Eos are connected
via a CAN bus cable. Connect one end of the cable into Eos CAN bus port and the other into any of the CAN
bus ports on the LX Zeus. LX Zeus receives power from LX Eos/Era. All data from and to LX Zeus and LX
Eos/Era goes via a single CAN cable.
LX Eos receives power via two power lines, which should be connected to 12V glider power source and
ground. The red wire is +12V and blue wire is Ground.
At this side the rounded rubber is touching the
back plate of display, do not push it too tight
At this side the rounded rubber is
pressed fully to the plate.

Connect supplied power cable with switch to 2-pole connector on LX Eos/Era.
LX Eos/Era and LX Zeus turn ON when the user switches the power ON. This is not the case if LX Eos/Era is
a standalone version, which has different hardware and requires a push on the knob to turn ON.
For more information about LX Eos/Era refer to LX Eos/Era manual!
1.4 Update procedure
LX Zeus software is constantly being upgraded. Please contact your local dealer for the latest upgrade.
The latest version, together with a change log, is always available on our website (www.lxnavigation.com).
The upgrade procedure is very simple, just follow these steps:
 Put the upgrade file (Zeus-x.y.z.kus) onto a USB stick
 Insert USB stick into LX Zeus
 Turn on LX Zeus (If it is already powered on it should be restarted)
 Hold VARIO/FLARM button until the blue window opens
 Select upgrade with a push on the Zoom rotary knob
 Find the update on the USB stick
 Select the file with a push on the Zoom rotary knob
 Wait for installation, when an Initial setup screen shows then the update is finished
 All devices connected to CAN bus will be automatically updated
 In a Double-seater configuration the system may ask if this is FIRST or SECOND seat (confirm
correct one)
 In case of Double-seater configuration repeat the whole procedure on the second seat LX Zeus
Important!
When LX Eos/Era is connected, the terminator must not be connected to the system, because there
is a terminator integrated in LX Eos. Only one terminator should be used at once.
