Rear Seat Device (LX8000D or LX8080D)

In two-seat gliders it is possible to install the LX8000D rear seat device.  The LX8000D looks
almost identical to the LX8000.  However inside the device there is no GPS or Flarm module.
The  rear  seat  device  must  be  connected  only  to  the  LX8000  via  the  RS485  bus  system.
Power  is  available  from  the  bus  hence  no  external  power  is  needed.    The  device  can  be
switched on only when the LX8000 is powered on.
The basic idea of two-seat configuration is that both devices work independently from each
other with the possibility to exchange various data on user request or automatically.

10.3.1

Data Exchange

Because the GPS and Flarm modules are not integrated in the LX8000D this data is received
from the LX8000 digital unit through RS485 bus.
After power on, the LX8000 also sends polar data and pilot information to have them
synchronised in both devices.
The user can define which data will be automatically synchronised between the LX8000 and
LX8000D.

Way point and task databases are not synchronised between the LX8000 and
LX8000D. To have databases synchronised you have to use the SD card and copy
files from the rear to front device or vice versa. See Chapter 5.1.5.4 for how to
copy way point files.

To set up data which is going to be received from the LX8000D, enter the “Rear seat device”
menu on LX8000 digital unit (see Chapter 5.1.12.5).
To define which data is going to be received from the LX8000 go to “Front seat device”
menu in the LX8000D unit (see Chapter 5.1.12.5).

Data is divided into two groups; flight parameters and navigational data. If a specific value
is checked this value will be automatically be received from the other device.
Check

MacCready

,

Ballast

and/or

Bugs

to receive the current MacCready value, current

ballast setting or bugs from the other device.
If

Waypoint

is checked a new way point target will be automatically assigned when the

user changes the way point target on the other device. A message

“Waypoint target

received”

will be shown on the screen and you will be navigating to the same way point as
