Installation
LXNAV remote stick is connected to RS485 bus through spring terminals on RS485 splitter.
Be careful, to connect correct colour wire to pin, which is marked with same colour.
PTT wires are connected to radio, SC is connected to Speed to fly input of vario unit.
If you are installing remote stick into double seater gliders or aircraft, be careful. Stick for rear seat is marked as DS. DS remote stick is programming to control repeater unit, which is installed on 2nd seat.
Remote with trim switch
Remote can be ordered with 3 position momentary switch for trimming purposes.
Such remote has four additional wires with label “IN: WHITE, OUT:RED” where
two white wires should be wired to positive and negative potential in glider,
and the second pair of red wires go to trim driver. Polarity is not important,
if the trimmer has wrong moving direction simply switch one pair of wires
between them and the direction will be reversed.
Remote with starter button
This option is for gliders with electric starters on internal engines. Remote
has red momentary button for starting engines on the ground or in the air. The
button is in a normally open configuration and makes contact when it is
pressed. Coaxial cable is separated from other wires and labeled as “Starter”
and should be wired to engine control unit as stated in their manual.
Functions
Function button (Fn) is custom button, which function can be set by user in setup – hardware – remote stick.
Remote without SC cable
We have been working very hard to simplify the remote stick so that we can
have the same functionality but use fewer cables. The LXNAV new remote stick
comes without the standard SC cable but the functionality is still available.
With the new stick, there is no more need to solder these wires to the vario
wiring loom. The SC function is programmable through LX80/90xx (version 5.x)
To make the SC function work with the new stick, please check the SC setting
in the configuration/setup page. For the LX80/90xx go to
Setup->Hardware->Variometer
Please make sure that none of input is set to “SC on/off switch” or “SC toggle button”. Configuration table for all SC switch options for new and old sticks
