1 System description

The system consists of a minimum of two units. One of them is a gliding computer the other 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, which 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 the 2.8 and 4.3 options use the 2x4 push button organization where as

5.5, 7.0 and 8.0 have a 5x3 push button organization. Every unit except the 2.8 option is delivered with a

suitable steel template which makes it possible to prepare a new cut out by hand. 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 2.8 Retrofit

Zeus 2.8 Retrofit is the same display size as Zeus 2.8 but differs in hardware. Vario (USB-D) module is

inside of the main unit and only a vario indicator is needed. Back plate is equal to LX 5000 (2x 15pin

connectors). If LX 5000 has a 25 pin connector, an adapter for 2x15 to 25 pin is needed, which can be

supplied from the LX Navigation Company. The purpose of Retrofit solution is that all wiring remains as is,

also an old vario indicator can be used!

1.1.3 LX Zeus 4.3

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

83x136x52 mm

Note!

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

LX Zeus v 3.4.3 10.9.2014

- 8 -

1.1.4 LX Zeus 5.5

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

106x146x52 mm

1.1.5 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

1.1.6 LX Zeus 8.0

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

161x218x52 mm

1.1.7 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.

1.1.8 LX Zeus CAI 302

All Zeus units can be connected to Cambridge vario CAI 302 as a plug and play solution. Cambridge vario

must be connected to Zeus Flarm port, so in case of CAI configuration Flarm cannot be connected to LX

Zeus. Zeus is exchanging following data with CAI:

QNH

Vario data

Airspeed

GPS

MC

Volume

CAI 302 vario is powered from LX Zeus device.

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 an GPS receiver. Units as Colibri, LX 20, VL and any other GPS source which is 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 in landscape orientation. Changing orientation is very easy and can be

done by pilot. See Colibri II user manual for more information.

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.)

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 update the firmware. 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

LX Zeus v 3.4.3 10.9.2014

- 10 -

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
