5Installation
Remote can be used with LX90x0/LX80x0 navigation units as well as with S8x and S10x
standalone variometers. Both Remotes are the same, the only difference is additional converter
on S type variometers. Standard version has four coloured wires and one shielded cable for
PTT although early versions of Remotes have additional cable for speed command. Depending
on the selected options there might additional cables or wires.
5.1 Power and communication wiring
Four separated wires with unique colours (blue, white, yellow and red) must be inserted into
spring terminals of RS485 splitter or CAN-485 Remote adapter. Be careful, to connect correct
wire to pin, which is marked with same colour.

5.1.1 RS485 (LX90x0, LX80x0)
LXNAV remote stick is connected to RS485 bus directly through spring terminals on RS485
splitter.
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 programmed to control
repeater unit, which is installed on 2nd seat.
For detailed description, correct settings and remote functionality read user manual
of LX90x0 and LX80x0 units.

5.1.2 CAN (S8x, S10x)
LXNAV remote stick is connected to CAN bus through 485-CAN Remote adapter. Spring
terminals are wired to remote and SUB D9 connector to S8x cable set via enclosed CAN Splitter
S8x cable.
Remote stick will not operate, until is registered on device. Remote stick can be
registered under setup-hardware-Remote stick. Registration must be done on each
unit (front and back seat).
For detailed description, correct settings and remote functionality read user manual
of S8x and S10x varios.

5.2 Push to talk –PTT
Coaxial cable labeled “PTT”is wired directly to PTT button and is independent of other
remote’s functionality. It should be wired to VHF radio as per their installation manual. Shield
usually goes to ground and center wire to pin on radio connector.
5.3 Speed command –SC
We have been working very hard to simplify the remote stick so that we can have the same
functionality but use fewer cables. The new version of LXNAV 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
LX90x0/LX80x0/S8x/S10x. To make the SC function work with the new stick, please check the
SC setting in the configuration/setup page. Go to Setup->Hardware->Digital inputs.
Please make sure that NONE of inputs is set to “SC on/off switch” or "SC toggle button".
However there is still an option for the customer to have previous version of remote stick,
where “SC”cable should be wired to V5 or S8x cable set, depending on the instrument used.
5.4 Wiring of function switches
5.4.1 Trim switch
Remote can be ordered with 3 position momentary switch for
trimming purpose. 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 trimmer has wrong
moving direction simply switch one pair of wires between them and
the direction will be reversed.
5.4.2 Starter button
This option is for gliders with electric starter on internal engines.
Remote has red momentary button for starting engines on the
ground or in the air. Button is in normally open configuration and
makes contact when it is pressed. Coaxial cable is separated from
other wires and labelled as “Starter” and should be wired to engine
control unit as stated in their manual.
