5.1.1 Installation of Options

All options except AHRS (LX8000D, LX8080D, Remote Control, Compass Module &
secondary vario indicators) are prepared to be connected to the RS485 system bus by use of
RS485 splitting units. Installation of any option is plug-and-play and therefore requires only
mechanical installation work. The LX8000 digital unit also powers all devices connected to
the bus. An automatic fuse built into the LX8000 digital unit prevents damage to the digital
unit should a short circuit in the wiring or in some attached device occurs.
