Operation - LX Navigation Zeus User Manual

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


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

 2x CAN bus*
2x User ports

 Flarm port (12 V power and data) *
