By using a RS485 bus system a wide range of optional interfaces can be easily connected to
the basic configuration with minimal installation work. The LXNAV bus system can be
extended easily by use of RS485 splitting units, which allow plug and play connection of
optional devices. The following units can be connected to the main system:
 Second Seat Device (LX9000D, LX9070D LX8000D or LX8080D): The unit
installed in the rear seat of the glider is powered and receives all necessary data from
the main unit. The communication between both units is exclusively via the RS485 bus
system.
 Remote Control: An extremely ergonomic leather-coated handle which includes 8
push buttons to operate the main display unit and also two additional buttons with open
wires. These two buttons can be used for instance as PTT for radio and SC/Vario
changeover command. A second remote control can be installed to control second seat
device or for side by side operation.
 Electrical Compass Device
 Secondary Vario Indicators (V5 indicator or V80 indicator)
