Flap Indicator unit
Basics
The LXNAV FLAP indicator is a small display unit with a red 10×7 LED matrix
display (sup for) indicating preconfigured flap positions. It can be used as a
part of main instrument or as stand-alone unit connected only to a LXNAV FLAP
sensor. The indicator has no buttons or any other user interactives. All
settings and firmware upgrades on the device are made over the main
instrument, or a PC via mini a USB cable.
At startup indicator will roll its name over the display as FLIND, (sup when
follows) followed by the “app” or “rec” and at the end, version of firmware
for example “v1.00”.
“app” (application) means that Flap indicator is in the operation mode, and
waiting either for settings from the main unit, PC or data from the FLAP
sensor to show its position. If the indicator is in the “rec” mode (recovery),
then it will not show any data. The reason could be in errors while upgrading
the firmware such as a cable disconnection, low voltage, etc.
In case the FLAP indicator is going to be used in a standalone operation, it
has to be purchased with:
- FLAP sensor
- RS485 splitter
- Power cable with termination

Installation
The flap indicator has a specific, non-standard enclosure that fixes to airplane panel with two M4 screws on 41 mm distance between them. Mount it horizontally with a mini USB connector on top.

Wirings
The LXNAV Flap indicator is connected to the RS485 bus through an RS485
splitter and a SUB D9 connector. The splitter is not part of the package. If
you don`t have a spare port on it, you must order another 485 splitter. Along
the flap indicator (supp should be mounted also) one should also mount a FLAP
sensor from which the indicator receives data.
Slave mode wiring
In the slave mode, connecting the FLAP indicator to an RS485 bus is the same
as for any other LXNAV instrument. Connect it to any free port on the RS485
splitter.
Standalone mode wiring
When the FLAP indicator is used in the standalone mode, connect it to an RS485
splitter along FLAP sensor. Two devices are powered from third connector on
which is power cable and a built-in termination resistor.
Setting flap positions
Putting the FLAP indicator in the working mode is selected automatically. When
it receives a flap setting from the main unit, such as an LX9000, it goes into
slave mode. This means, the indicator is just listening on the RS485 bus. The
second option is, when there is no main unit. In that case, it goes in
standalone mode and is constantly asking the FLAP sensor for the current
position. The standalone mode is selected right after the user sends settings
to the FLAP indicator over the USB. Setting the flap positions is described in
following chapters.
LX80xx, LX90xx
On the main unit, under the “Setup” menu, go to “Hardware” and “Flaps”. Put
the flaps (sup to) in the upper position, move the cursor on the instrument to
the first box, and click the “SET” button. This will save current angle set
from the FLAPS sensor to the first box. Write the name for this state, and
repeat the same action for the remaining positions. When this is finished,
click the “CLOSE” button, and all data will be sent to the FLAP
indicator.
If the positions are already saved, after a first startup with the FLAP
indicator, wait for a minute, and the instrument is going to update the
indicator automatically. When it receives data, it will save them to its
internal memory, and show them next time right after the system startup.
PC via mini USB
This option is available only for the standalone mode of the FLAP indicator.
Settings made over the Flap configurator tool will not be sent to the main
unit, instead they will be rewritten by LX80/90xx.
Connect the mini USB connector to the FLAP indicator after powering up. On
your computer you should see a new serial communication port. Under
“Settings”, in Flap configurator, select it, and then press the “Connect”
button just next to “Settings”.
Now you are able to see the current flap angle. Put the flaps in the upper
position, write its name in the “Pos1 name” text box, and press the “Set”
button to determine the angle. Repeat the same process for the remaining flap
positions. When it is done, click the “Save” (sup button) and “Disconnect”
buttons. Now you are ready to use the FLAP indicator with the FLAP
sensor.
Updating firmware of Flap Indicator
Latest firmware for LXNAV instruments can be found on:
http://www.lxnav.com/download/firmware
Update is possible with one of the following two examples:
LX80xx, LX90xx
Firmware updates can be done via a main unit such as the LX 80/90xx.
-
Start the main unit with the connected FLAP indicator.
-
Go to: Setup->Password and type in “89891”
-
If there is only one update file, it will automatically update the indicator. Otherwise it
should be selected manually. The update filename name is “App_FIND_x.yy.lxfw”, where x.yy is the firmware version. -
When the update is done, the FLAP indicator will restart with the new firmware and the previously saved settings.
PC via mini USB
The second option for firmware updating is via a PC, and is the only way when
the FLAP indicator is used without the main unit.
-
Download FlashLoader485App (PC update tool) from the LXNAV website under the section for S7 instruments: www.lxnav.com/download/firmware
-
Connect the mini USB connector to the FLAP indicator, and on the other side, to your PC.
-
Power up the indicator over the SUB D9 connector.
In this case, when the USB is connected before powering up the instrument, it goes in recovery mode, which can be seen from the welcome text “FLIND rec vx.yy” on the screen. From this moment on, the firmware can be updated. -
Choose the correct serial port. Baudrate has no function – leave it as it is.
-
Chose the firmware file App_FIND_x.yy.lxfw, where x.yy is the version.
-
Press the Flash button, and the update will start.
After a successful update, the indicator will restart and go back in recovery mode; thus the USB has to be disconnected and the indicator repowered. If the update procedure is interrupted (supp of any case) for any cause, the FLAP indicator will cycle in recovery mode and it has to be updated again following the process described above.
