2. Introduction
The LX160 is an electrical vario meter and final glide calculator with the ability to receive
NMEA sentences from an external GPS device (COLIBRI, LX20, LX400, GARMIN …). This way
the LX160 calculates a final glide to a point selected on the GPS device. The LX160 calculates
the wind component. Without the external GPS device, the LX160 functions like a normal
electrical vario meter with final glide calculation. The pilot just enters the parameters
(distance, wind component, altitude of target point, polar). This instrument is made on the
LX5000 principle, so all the mathematics about final glide calculations are the same as the
LX5000.
This manual will teach you about the device, its functions and all the advantages. Please read
it carefully before you install the device. The best way to learn basic and more advanced
functions about the LX160 is to turn it on at home and go step by step through this manual.
We have done our best to achieve, as little handling during the flight as possible, if the on-
ground preparation has been optimal.
The manufacturer doesn’t take the responsibility for possible mistakes or misprints in this text
and gives no guarantee for accuracy of this manual.
This manual has been written with the greatest care and we have done our best to avoid any
mistakes but with all respect please check any doubtful statement and let us know. We would
be very grateful and we thank you in advance for any comment.

3. Description of switches
Figure 1 Switches
ON/OFF:
Switches power on or off.
SC/VARIO/AUTO: (mode selector)
•SC is speed command mode
•VARIO mode
•AUTO mode
MC:
After MC switch is activated the upper number shows the MC. After
App. 1 second this disappears. With a short press MC
increase/decrease for 0.1, with a long press MC increase/decrease
for 0.5.
BUGS:
•upper position (2) 10% glide ratio
degradation (
default
)
•middle position (BUGS) 0% glide ratio
degradation (
default
)
•lower position (1) 5% glide ratio
degradation (
default
)
BALLAST:
•upper position is full ballast (2) +20% of min. load
(
default
)
•middle position is without ballast (BAL)
•lower position with half of ballast (1) +10% of min. load
(
default

FILTER: (vario filter)
•upper position (2) 3 seconds-
default
(very
strong filter)
•middle position (FIL) 0.5 seconds-
default
(almost no filtering)
•lower position (1) 1.5 seconds-

(weak filter)
AUDIO VOLUME:
With a long press the volume increases/decreases faster, with short press
volume is increased/decreased slower.

Figure 2 LCD indicator
The unit is powered from LX 160 via 485 cable. On the back there are two SUB D 9P
connectors, which are completely parallel. Both could be used like inputs or like outputs for
other units (LCD). 485 protocol is delivering data strings for four independent LCD vario
settings. Which data string will be accepted is defined using different positions of the DIP
switches on the backside. There are no other settings on the unit.

5. Pneumatic
On the rear side of LX160 are three probes.
•On TE probe is connected total energy or static, if we havent total energy. If static is
connected, vario is not compensated. Electronic compensation is necessary.
•Pst is static pressure needed for speed.
•Ptot must be connected on total pressure in nose of glider (pitot). If this probe is not
connected properly, instrument will not work good. (on speed depends all important
calculations like glide path, speed commad, netto relativ, polar…)

6. Power on
After powering up the LX160, wait app. 40 sec. to warm up the sensors. On the LCD
indicator we will see displayed LX160 and the number of version.
Figure 5 After power on
7. Two main working modes
The LX160 has two main modes: VARIO and SC (speed command) mode. In the vario mode
the needle displays vario, the upper number displays average. The lower number display is
decided by the user in the “INDIC” set-up menu.
Figure 6 Vario mode
In SC mode, the needle displays SC, other information is selected by the user, the same as
in the vario mode.

Figure 7 SC Mode
The SC ring always displays SC value, no matter in which mode the LX160 is in.
Settings for VARIO mode and SC mode are different
Warning!
Altitude, which is displayed on the lower number is always set on zero (QFE)
after power on. In case you switch off the instrument during flight, the old
QFE remains if IAS is greater than 40km/h
