ILEC SN10 Flight-Computer Resources
Last Update 20-May-2013
The ILEC SN10 is manufactured and sold by ILEC Gmbh,
in Bayreuth, Germany.
The ILEC web site is the primary source for the current manual and software:
In North America, ILEC products are sold and supported by:
Knauff & Grove
For Australia and New Zealand: ILEC Australia

In the unlikely event your ILEC instrument needs to be returned to
ILEC for service, please carefully follow these
shipping instructions to avoid delays in service:

For many versions, the ILEC SN10 has supported FLARM, and pilots
world-wide use FLARM to provide GPS as well as traffic info to the SN10.
Enable the optional FLARM support features on the "SN10 Options 2" page:
Make sure you set both FLARM and ILEC SN10 GPS baud rates to 19200 !
Your ILEC SN10 will optionally decalare your task from the SN10 into the FLARM (only works for IGC-approved versions of FLARM).
PowerFLARM brick is supplied with a DB-9 cable to ease connections. This cable is color-coded but please double-check the pin connection of each DB-9 wire before soldering.
|ILEC SN10 Function||ILEC Panel Cable wire color||DB-9 Cable wire color||DB-9 Pin Number||PowerFLARM Brick Function|
|NMEA-format serial input||Green||Brown||2||serial port #2 NMEA-format output|
|NMEA-format serial output||Yellow||Red||3||serial port #2 NMEA-format input|
|Do NOT connect to SN10 power output !||Blue||7||+12v power input|
|Do NOT connect to SN10 power output !||Yellow||5||Power ground|
Note: The PowerFLARM serial port in the DB-9 connector must be
enabled (default it does not operate).
Please configure your brick to enable serial port #2,
using a USB-memory stick,
following these instructions:

With the ILEC SN10 USB adapter,
a USB "thumb-drive" "memory-stick" can
be used to save flight logs, load new site information into the SN10,
and load new SN10 software versions - no more carrying a laptop
to the glider, searching for the SN10 PC-cable, or fighting with
cranky USB-to-serial adapters. See:
ILEC SN10 Manual supplement for USB adapter
Download the file
ILEC SN10 USB
adapter software ZIP
and unzip it onto a memory stick (you should see ILECUSBA.HEX).
Follow the update instructions in section 10.5
of the USB manual supplement above. The link above points to the most
version of ILECUSBA.HEX. Updates to the USB software are detailed below.
Some DOS and Windows text editors stick a DOS-specific control character (ctrl-Z) at the end of a file. The USB adapter, as with many of us, was surprised and confused by this ctrl-Z, and the SN10 displayed an error "USB-NDB Error, Line 554, unrecog. record" with the line number pointing to the last line of the file. This update of the USB-adapter software (not the SN10 software) ignores the ctrl-Z - update the USB adapter software as described above.
The SN10 got pretty excited when presented with a USB memory stick requiring too much power. To stop getting the warning message "USB stick requested too much power", it was not only necessary to unplug the stick, but to turn the SN10 off and on again and clear one last warning. This software update calms it down, only one warning ! Thanks to JJ for bringing this to our attention and sending me a stick that actually requested more than 100ma. A tenth of an Amp should really be enough power, but there are some el cheapo sticks out there that ask for more... This bug is in the software within the USB adapter (not the SN10 software) - update the USB adapter software as described above.
We found a bug that caused some NDB files not to load properly (only some NDBs without airspace information). This bug is in the software within the USB adapter (not the SN10 software) - update the USB adapter software as described above.
ILEC SN10 pilots who haven't yet installed an SN10 USB adapter use a laptop to upload turnpoint and map data to the SN10, and to download flight logs from the SN10. Most pilots have no problems, however...
You must use the ILEC PC-cable to connect a PC to the SN10. The wrong cable will typically short out various SN10 signals and power supplies, causing the knobs and buttons to stop working, and possibly damaging the SN10 and/or the PC. The ILEC PC-cable looks like the picture at left.
plug a USB-serial adapter directly into the SN10 or panel cable.
Do not use a "standard" serial cable, or the cable you found underneath the desk in your clubhouse, or you will have problems.
The elimination of "real" serial ports on new PC's
has resulted in much pain and suffering.
We really suggest you get an ILEC USB-adapter to avoid needing a PC at the glider.
However, if you must use a PC, find which USB-to-RS232 solutions work, how to use a Mac instead of a PC, and what to avoid here:

Several people have had badge applications denied because of a missing aircraft registration in a Volkslogger flight log. If you are using a Volkslogger with an ILEC SN10, please follow the instructions below.
IF YOU DO NOT FOLLOW THIS PROCEDURE THE "AIRCRAFT REGISTRATION" WILL BE BLANK IN YOUR LOG FILE, AND YOUR BADGE OR RECORD CLAIM MAY BE REJECTED.
To declare a flight for an IGC badge or record, you will need to fill in the "Aircraft Registration". While the ILEC SN10 can declare the task, pilot, and contest ID to a Volkslogger, you must fill in the aircraft registration (N number) using the Volkslogger directly.
(1) Using the 3-buttons on the Volkslogger, enter your aircraft
This is under the menu:
FAI > EDIT > INFO > AIRCRAFT-REG
(2) IMMEDIATELY erase the flight recorder memory:
ACT > MEMCLR
Paradoxically, erasing the Volkslogger's memory
is what permanently saves the current FAI info.
If you do not erase the memory after entering the registration, the next time you declare a task from the SN10, the aircraft registration field will be BLANK !
Note: "Declare Task" does NOT save the aircraft registration permanently ! You must ACT > MEMCLR !
Once you've performed this procedure, you will never need to re-enter the aircraft registration in the Volkslogger - it will be permanently saved.
Please lobby your SSA Regional Director and our IGC representative to use common sense when homologating badge and record claims. The aircraft, pilot and competition ID in the flight log, plus an official observer's signature should be enough !
The following are technical notes to help create software and services that work with the ILEC SN10.
The ILEC SN10 optionally produces output to drive an
in-cockpit PDA. This output is used by some
popular PDA software. Here's how it works:

The ILEC SN10 displays a moving map including airspace
features. Starting with airspace information in Tim
Newport-Peace's format, the information is translated
into the SN10's internal format and appended to the
Using utility software we provide, this is performed
automatically by some popular PC programs and web sites,
including StrePla and John Leibacher's World-Wide
Turnpoint Exchange. Here's how the process works:
