5.2.2
Installation of Options
All options (Rear Seat Device, Remote Control, Compass Module & secondary vario
indicators) are prepared for connection 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 main display unit also powers all devices connected to the bus. An
automatic fuse built into the main display unit prevents damage to the digital unit should a
short circuit in the wiring or in some attached device occur.
5.2.2.1
Remote Sticks
The LXNAV remote stick is connected to the RS485 bus via a RS485 splitter.
Ensure that you correctly connect each coloured wire to the pin which is marked with same
colour.
