1 System description

The system consists of a minimum of two units. One of them is a gliding computer and another unit is a 57 mm vario. The vario unit is also available as an 80 mm option. The gliding computer has a sunshine readable and anti-reflective 5.5 inch colour display and a high power Linux running computing device. The vario is a standalone unit and has its electronics based on high precision digital sensors and transducers. The connection between vario and computer unit is via LX system bus. System extensions (second seat

unit, remote control, compass ....) are also possible after connecting the LX system bus solution. All

connections are plug and play, what means no specialists are required to install the system.

1.1 Screen size options

LX Zeus comes in five different screen size variants, which makes it possible to install the LX Zeus system into practically any instrument panel. The complete electronics and also all functions are the same for all variants. The only difference is, that 2.8 and 4.3 variants uses a 2x4 push button organization and other options have a 5x3 push button organization. Every unit except the 2.8 model, is delivered with a suitable steel template which makes possible to prepare new cut out by hand after using of hand tools. There are two orientations possible*: landscape or portrait orientation. This can be specified during ordering. The user can also change the orientation in the system settings. *Zeus 2.8 is only available in landscape orientation.

1.1.1 LX Zeus 2.8

This version of Zeus can be installed into any normal 80 mm panel cut out and therefore does not require an instrument panel upgrade. Display orientation is only landscape.

1.1.2 LX Zeus 4.3

The display diagonal of the system is 4.3 inch and has following outline dimensions:

83x136x52 mm

1.1.3 LX Zeus 5.5

This is the most common used variant and comes with 5.5 inch display. Layout size is:

106x146x52 mm

1.1.4 LX Zeus 7.0

This version size can be fitted in the majority of instrument panels used in modern gliders. The display size is 7 inch and the unit layout is:

110x190x52 mm

Note!

Pictures used in this manual may slightly differ from the LX Zeus original screens.

LX Zeus v 3.0 25.6.2014

1.1.5 LX Zeus 8.0

This is the biggest LX Zeus model and its display diagonal is 8 inch.

161x218x52 mm

1.1.6 LX Zeus Mobile

LX Zeus Mobile is a derivate from LX Zeus 4.3. The unit uses a 4.3 inch display, the same as by Zeus

4.3. The unit is prepared to be installed as an integral part of the panel, but can be also used as a mobile device installed on panel by using a gooseneck. A vario unit is also a part of delivery and its default configuration is a black box solution. An upgrade to color display and the needle is possible at any time.

1.2 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 make it possible to connect (plug and play) a various palette of GPS signal sources, as the unit does not have integral GPS receiver. Units as Colibri, LX 20, VL and any other GPS source which are capable of delivering NMEA data at nearly any baud rate, are compatible.

A special plug is provided for Colibri II connection and in that case Colibri II is 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 is powered on. automatic power off after Zeus will be switched off and the system is no longer in flying mode; if

flight status is detected, Colibri II will continue logging its own internal battery.

downloading of flights via Zeus USB stick

When two GPS sources are connected at the same time, both signals are combined and losing one of the GPS sources will not degrade system availability. Colibri II is used as an IGC flight recorder in the 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 in the same way as by an integral flight recorder. The Colibri II unit can operate in portrait and also in landscape orientation. Changing orientation is very easy and can be done by pilot. See Colibri II user manual for more information.

Commercially available versions:

Rotary switches and push buttons

There are 8 push buttons and two rotary switches on the front of the unit. Also the rotary switches have a double push function (short and long press). On one side there are five push buttons which all have a double push function (short and long press) and on the other side there are three push buttons with one push function. Buttons are labelled and this makes unit manipulation very easy. (Zeus 2.8 has a 4x4 push button organization.

LX Zeus v 3.0 25.6.2014

Both rotary switches are multifunctional as follows:

Default functions:

audio volume adjustment function zoom selector

In edit:

zoom: scrolling and press confirmation volume: bigger steps of scrolling and escape/cancel by pressing

1.2.1 USB and SD port

An A-size USB port is situated on the front panel. The port is exclusively used for data transfer and firmware updates. The customer can also easily do the firmware updates. The SD port is only used when a Flarm is connected (Flarm Red Box, Swiss Flarm and optionally Flarm Mini Box). The SD port makes direct communication with Flarm possible, which means downloading of flights stored in Flarm, uploading of declaration and also Flarm updating.

1.2.2 Connections

On the back side of the unit there are following connectors:

4x 485 system bus (Zeus 2.8 has 2x 485)* 2x CAN bus** Colibri II port (5V and data)*** Flarm port (12 V power and data)**** 2x Flarm display outputs 1x Flarm SD 1x OAT plug to connect OAT sensor

Zeus 5.5/7.0 with AHRS:

1x Pst connector 1x Ptot connector 1x USB (not in use)

* 485 connects LX Zeus to:

USB D 60 Vario unit Remote control stick Secondary Vario indicators Compass module Voice module

** CAN bus:

Connects Second seat unit

*** Colibri II port:

Makes possible to arrange direct connection of LX Zeus to Colibri II only via cable (special cable

required, is included when purchased together)

**** Flarm port can be also used to connect any other GPS source which has an IGC standard connector. For instance: Colibri LX 20, VL… If Flarm is connected, two Flarm displays can be connected to the system by using Display 1 and Display 2 plugs. The SD connector is directly connected to the micro-SD card reader on the front of the Zeus.

1.3 Software

SW package is completely developed by LX Navigation and is running on Linux operation system. The logic used kept the well-known LX Navigation philosophy, but some new approaches have been involved. The SW is continuously developed and upgrades are regularly published. Upgrades of SW can easily be done by user without requiring any passwords. Contact your dealer to get notified of future updates.

simply move the frame to the last position, press 1-4 and a new row will open. The display configuration may consist of one, two or three bottom rows. See Setup/Layout for details.

1.7.1.3 Header customization

Customization of the header should be done in the similar way as by bottom row. After a long press on volume the customization can start. Size of indicators can be adjusted by rotating Volume button. Box types can be selected after press on Zoom button. Rotating the zoom button will give the option to select the position for the indicator.

2 Setup

Setup menu is available after short press on SETUP labelled push button. The menu is divided into two sections (Pilot and System settings). System settings are settings that are valid for the whole system and are not pilot specific data. Pilot connected items may vary from pilot to pilot and depend on individual requirements. Suitable symbols with text will help you to find the menu of interest.

use Zoom button and rotate it to find out menu of

interest (selected menu size will increase)

use push function of Zoom to enter menu.

2.1 Pilot specific settings

The data stored in this part of Setup are pilot specific data. After pilot selection during booting the data of individual pilot becomes active. All settings are saved to the personal saved pilot profile and are active when the pilot is selected (reserve altitude, logger settings, NAV BOX line, layout settings, task colours etc…)

2.1.1 Pilots

Pilots name and certain personal data can be stored. All stored pilot names will be offered during booting. Selection of one pilot is mandatory. The system offers

one name called as DEFAULT - can be used as a default pilot. Furthermore plenty of empty positions are offered

and this can be used for pilot names input. Additionally to the name some additional parameters can be entered,

such as pilot’s weight, default ballast and reserve altitude

– all that will be calculate into final glide. Limiting altitude

means setting of altitude limit that will turn on the altitude warning alert. You can also save user (pilot) settings to the USB stick and import user by pressing the buttons: Import user (VARIO/FLARM) and Save user (TSK/MOVE). There is also an option to put a password

to each pilot profile, to prevent, that other pilots flying with the same unit will be able to change settings to the pilot (this function was especially developed for flying in the aeroclub). After press on clear password a password will be removed, also valid for delete user.

2.1.2 Audio settings

This menu defines audio configuration. The audio generator is a part of the vario unit (USB D 60), but settings are stored in LX Zeus.

Speed command mode:

Defines audio in SC, there are several variants

the most common used setting is both which means no beep indication by positive deflections.

Speed command volume:

Defines audio volume in SC, may be increased

decreased…

Vario tone:

Defines audio in vario mode, you can adjust

frequencies and also types of audio, use Test

vario after adjustment

Alarm: The audio generator is also capable to generate

some alarms (warnings), combining two frequencies. Set frequencies and time intervals and use Test to check.

Note!

All settings active at the moment of new pilot creation under “Pilot” will be adopted.

Use Test vario option to play the audio variant. It is important to change over to SC before test;

otherwise vario audio variant will be

reproduced.

The frequencies set are also valid for SC audio.

2.1.4 Vario settings

Settings in this menu define vario characteristics and some other important inputs connected to vario and speed command.

Vario:

vario filter defines dynamic of vario needle. Lower

number means faster reaction and vice versa.

smart vario* Integration 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

LX Zeus v 3.0 25.6.2014

- 22 -

*LX Zeus has a connection for an external speed command switch, which is wired to the vario unit (USB

D 60). With using an external switch it is possible to switch between SC and Vario manually. Setting the

External switch mode to ON means that closing of the switch will cause SC mode, and setting External switch mode to OFF means that closing the switch will select Vario mode. There is a third option by

setting External switch mode to Toggle and connecting a push button. Now each press will toggle between SC and Vario (obligatory setting when using the LX Remote).

2.1.5 Indicators

By Indicator, the vario indicator with its mechanical needle and colour graphic display is meant. 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 / lower digital indicator, battery indicator and GPS signal 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, this cannot be changed.

Some explanations of terms:

Vario needle : means needle function in vario mode, alternatives; vario, Netto*, SC, Relative** SC needle: means needle function in SC mode, alternative; Netto, Relative, Vario Vario upper nr: display indication by option: integrator, time, flight time, leg time Vario lower nr: display indication by option: altitude, distance, glide difference, true air speed, leg

2.1.5.1 Secondary indicators

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 indicator 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 and you will be able to adjust settings on Zeus.

2.1.6 Flarm

In the Flarm menu it’s possible to select or deselect the Flarm privacy mode, and also showing objects on the

map at specified zoom level.

2.1.7 Logger - Flight recorder settings

LX Zeus uses Colibri II as an IGC approved flight recorder. Both units collaborate so that all necessary settings can be sent to flight recorder (Colibri II) via Zeus and meaning that no actions on Colibri II are necessary. Recording interval is set to 9 seconds per default; event repetitions are set to 20 and event fix interval to 1.

Extra recording means that user can select also recording of Ground speed into log file.

This menu is usable only if Colibri II is connected to

Zeus. If you change settings, these settings won’t

change in Flarm or any other Loggers.

In a double seat configuration the second seat pilot is also able to change logger settings. The process is equal as on first seat.

2.1.8 Airspace management

All settings connected to AS management are available in this menu.

Example of Hide airspace above

Default warnings for airspaces are set to 2 km horizontally and 100 m vertically, but these warning settings can be adjusted.

Note!

Pilot and glider data are sent after task Declaration process has been executed. See section flying.

Note!

Hide airspace above option will remove airspace

sections which are higher than set. This will reduce load on graphic page significantly.

2.1.9 Wind

LX Zeus is able to measure wind under different methods. The method can be selected in Wind menu. Wind calculation results are shown as a standalone indicator in main graphic page and also as NAV BOX if set.

Pilot can choose between two circling methods, which measures wind during circling and two straight model methods during straight flight

Circling method

Speed difference is based on ground speed (GS) oscillation due to wind influence in circling. The

method is active exclusively during climbing process. During straight flight the wind data remain unchanged. The process is started (automatically) after circling is detected. After two* circles wind indication (direction and speed) will be updated. The method is based on fact that the ground speed is affected by wind. GS is maximal by tailwind and minimal by head wind. This phenomenon is used by GS difference calculation method. To increase reliability two turns are necessary for a new result. To get result the pilot should do two turns as a minimum, more turns will improve result. Note that up to 90 degrees more is required, as some time is needed to detect circling status. It is important to keep constant speed during circling.

Position drift calculates wind regarding to position offset during circling. Such a method needs

more circles (from 4 up to 8). Number of circles should be set in Drift circles option. If both methods, straight model and position drift are selected Zeus indicates a combined result.

Straight model

None: if you select none, you will have the wind from the latest circling method Compass: Compass module should be connected to the unit on 485 bus. Wind calculation is

based on well-known wind triangle method. Airspeed, ground speed and wind create a triangle of vectors. A compass device offers magnetic heading, which defines direction of airspeed vector. To measure wind by compass a straight flight with speed and direction as stable as possible is required

Head/Tail – no circling method needed (shows difference between GS and IAS) Time for straight flight: time in seconds that will be taken for one measurement (valid for

straight model). Longer period means better result. Valid only for Compass method and not for Component.

Drift circles: means how many circles are required to calculate the position drift.

Compass assistant: is a special symbol that appears on the display and helps to keep flight

parameters (speed and direction) stable during calculation.

Manual wind settings

Set manually - user can set manually wind speed and direction

* Compass is a standalone electronic device which can be connected to LX Zeus 485 bus. Integrated AHRS option also offers the same functions. The unit’s task is delivering of magnetic course to Zeus computer.
