3Basics
3.1 LXNAV S8x/S10x at a Glance
The LXNAV S8x/S10X is a standalone digital variometer, final glide calculator and navigation
system with a simple moving map. The LXNAV S8x/S10x has both GPS/FLA M and PDA/PNA
input/output. The unit has standard dimensions that will fit into a glider panel with an
opening of 80 mm diameter (3.15”) or 57 mm diameter. It is also able to supply a PDA/PNA
with power (5VDC/1A). The unit has an integrated high precision digital pressure sensor and
inertial system. The sensors are sampled more than 100 times per second. eal Time Data
is displayed via a vario needle, an airspace map and up to 4 variable numeric fields displayed
on a QVGA 320x240 pixel, 3.5-inch (S80/S100) or 2.5-inch (S8/S10), high brightness (1200
nits) colour display. To adjust values and settings the LXNAV S8x/S10x has two rotary push
button knobs and three additional push buttons.
The LXNAV S8x/S10x can be expanded with one or more repeaters (LXNAV S8x/S10x) via
the CAN bus. This allows both pilots in a two-seat glider to have independent control of all
functions of each unit in the front or the rear seat.
The
S10x
unit
includes
a built
-
in IGC
-
approved
flight
recorder,
a
Bluetooth module
and its own backup battery which provides from 3 to 4.5 hours of independent
operation.
The S10x is also capable of running HAWK system, which provides pilot a real time
three dimensional wind. You can learn more about HAWK in chapter 7.

ev #37 Version 8.0 April 2021

3.2 LXNAV S8x/S10x Features
•An extremely bright 3.5’’ (S80/S100) or 2.5” (S8/S10) QVGA colour display readable
in all sunlight conditions with the ability to adjust the backlight.
•Two rotary switches (knobs) with push button function and three push buttons are
used for input.
•Pre-loaded polar database for nearly all gliders.
•GPS/FLA M and PDA/PNA input/output.
•FLA M Indication if a FLA M is connected to the GPS/FLA M port.
•Programmable “needles” for selectable data such as netto vertical speed, relative
(super netto) and vertical speed (vario).
•320x240 pixels colour screen for additional information such as average, thermal
vario, time, speed etc…
•Many custom audio settings.
•100Hz sampling rate for very fast response.
•Speed to fly indication.
•TE compensation can be selected to be either pneumatic TE probe or electronic TE.
•Audio equalizer, for custom vario sound performance.
•Audio thermal assistant.
•Built-in high level, IGC-approved flight recorder.
•Built-in Bluetooth module.
•Backup battery.
•Engine noise level sensor (ENL).
•Built-in GPS module.
3.2.1 Interfaces
•GPS/FLA M port input/output on S232 level ( J12 connector, none-Standard IGC)
(12V/2A)
•PDA port input/output on S232 or TTL level for PDA/PNA devices with 5V power supply
(8 pin J 45, 5V / 1A).
•Audio port (Standard 3mm phone jack).
•1Mbit CAN bus for extension to S8xD repeater or emote stick (CAN remote).
3.2.2 Options
By using a CAN bus system, a second seat device can be connected. The unit installed in the
rear seat of the glider is independently powered and receives all the necessary data from the
main unit. The communication between both units is exclusively via the CAN bus system
( emote stick, Compass module, Second seat device).
3.2.3 S8/S80 Club
The S8 Club and S80 Club are special price performance editions of the basic S8 and S80
units. The following features are optional on this device: Task mode (see Chapter 5.6),
Digital inputs (see Chapter 5.7.13.1), Pilot profiles (see Chapter 5.7.15) and Airspaces
(see Chapter 5.7.8.3). Every option can be upgraded separately at any time. To purchase
additional options please contact LXNAV.

4S stem Description
4.1 Push Button – Rotar Switches
The two otary switches also have a push button function. The LXNAV S8x/S10x detects
short or long presses of the push button. A short press means just a click, a long press
means pushing the button for more than one second.
4.1.1 Power Button
The system is powered up by pressing any of the push buttons or a press of either of the
rotary knobs. A long press of the upper rotary knob will turn the S8x/S10x off. Use this
instead of the avionics master switch.
4.2 Rotar Switches
The upper rotary knob is designed for direct volume control. A short-press on the upper
rotary knob will produce an option to select between options and adjust volumes for the
Vario, Speech and FLA M beep.
A long-press on the upper rotary knob will shut down the system cleanly.
The lower rotary knob is used to adjust settings within the current mode or within menus.
With the lower rotary push button, it is possible to toggle between the MC and the Ballast
and Bugs settings. In all other menus this knob is used for setting values and editing texts.

ev #37 Version 8.0 April 2021
Page 20 of 121
4.3 Buttons (Three)
The three buttons between the two rotary knobs have fixed functions. The top button is ESC
(CANCEL), the middle is to switch between modes and the lower button is the ENTE (OK)
button. The upper and lower buttons are also to rotate between subpages in the WPT and
TSK modes.
4.4 Switching on the Unit
Pressing any of the buttons or rotary knobs will turn on the S8x/S10x. The first LXNAV
welcome screen will appear with the system information (Device name, Version, Serial
number...)
The S8xD rear seat unit cannot be powered up before the S8x/S10x has been
powered up.
When the boot procedure is completed the setup elevation dialogue will be displayed.
The user must set either the Elevation or the QNH with the lower rotary button. After
pressing the lower rotary button, the user can switch between the Elevation and QNH
dialogues. As soon as the settings are set the middle button must be pressed to proceed.
The upper push button also has the power OFF function.
