SN10 Software Revisions

ILEC Australia

SN-10 Operating Software Revision Listing

Full Version Listing (details below).


(1) With the introduction of the new SN-10b (the new improved display screen) please make sure you download the correct System Software.

If you accidentally load the SN10B software into an SN10 (or the SN10 software into an SN10B):
- your SN10 screen will be blank,
- your SN10 will sound an audio SOS (dot-dot-dot-dash-dash-dash-dot-dot-dot),
- you will need to load the correct software before you can use the SN10 !
Load the other software !  The SN10 will wait for the new software after it beeps SOS.

(2) Upgrading from 2.10 or 2.xx and above will not require reloading your map or turnpoint data; whatever 2.10 data is in your SN10 will be preserved, however...

(3) If you upgrade from a version earlier than 2.00 to version 2.00 or later, you will lose any turnpoints you entered at the SN10.  Make sure you have the NDB files you will need ready before upgrading your instrument.
Return to top.

* For instructions on updating your SN10 software, see:
- SN10-USB-adapter manual supplement using the SN10-USB-adapter
- WINupdat.TXT using a PC with 16-bit or 32-bit Windows
- DOSupdat.TXT using a DOS PC (or DOS emulator on PDA)

* See MAPHELP.TXT for a discussion of moving map data preparation.

* Please see DBFORMAT.TXT for a description of the NDB (turn)point data format.

Notable features of version 2.41 (11-July-2016):
- For OLC pilots: During an AAT task, points not already marked achieved
can be updated, and you can add areas, without resetting the task.
You still need to switch to "Setup" mode to change AAT points.

Return to top.

Notable features of version 2.40 (3-Nov-2014):
- Airspace-warning feature with following notes:
  - FOR BEST RESULTS: airspace data in NDB files should be regenerated
using AIRPAR32 from 2.40. John Leibacher has already regenerated
airspace in all NDB files on the WWTPX. Output from the new AIRPAR32
is compatible with older SN10 software.
  - Enable airspace warnings on the "SN10 Options 1" page
  - You will be warned regardless of altitude (even if you can overfly
or underfly the airspace)
  - If there are multiple airspaces you would touch, you may only get
a warning for one of them.
  - Airspace warnings will not repeat until 2 minutes have passed,
and will repeat until your trajectory does not enter the airspace.
  - If you fly parallel to an airspace boundary, you will not get a
warning until you turn towards the airspace, and YOU MAY NEVER
GET A WARNING if you turn and quickly cross the boundary...
  - Airspace warnings display the airspace name with altitude floor
and ceiling, for example:
          !! Airspace !!
          !! Warning !!

         R4811 0800-1
                5.8 ahead
         Alt: surface
          to FL180
         ENTER for map...
on the moving map, it will generate a warning if you approach it.
If you do not want warnings for airspace like MOAs, don't include
them (set INCLUDE=NO in the TNP file) or disable SN10 warnings.
  - Once you clear an airspace warning, there is no way to get it back!
Make sure you read the warning before you press HELP or ENTER.
  - If you prepare your own airspace or NDB files, please see
MAPHELP.TXT for help using AIRPAR32 (MAPHELP.TXT is available from
your Start Menu, under ILEC SN10 utilities help).
  - If you encounter ANY problems or quirks, please send me:
    - a description of the issue
    - the flight-log from your SN10 (not a different logger!)
    - the NDB file you were using
    - if possible, the TNP airspace file used to generate the NDB
- Incorrect clubmode HELP fixed: Note that in club mode, alternates on
moving map calculate glide to arrive at setting ARV AGL, not 150m AGL.
- Limit frequency of FLARM error messages to avoid blocking SN10 use
- Reduce annoying warnings (FLARM errors, USB gadget startup delays)
- Demo program bugfix: Again runs properly on Windows XP (SP2 or later)
- AirPar32 Improvements: Supports airspace warnings, faster map drawing
- DBC32 now warns of confusing almost-duplicate-names (41Start, 42Start)

Notable features of version 2.36 (30-April-2011)
- Includes IGC-style flight-log validation DLL IGC-IEC.DLL
- Includes latest (August 2010) USB-adapter HEX file ILECUSBA.HEX
Update your USB adapter software to get these improvements:

- FLARM neighbors moving map display page
- declare SN10 task into FLARM
- AAT workload reduction features. On the moving map page, ONLY when in
AAT mode (switch to "A"), and ONLY when the cursor is on one of the
four control fields at lower left:
(1) Extended HELP shows stats for the remaining task,
so there's no page switching to see how an adjustment affects
the ETF and amount over and under. Press HELP on any of
the four control fields at lower left, and you'll see this:
   == Task To Go ==
   Distance   203.0
   current MC   2.0
   ==== Times =====
   ETF         2:07
   Remaining   1:46
(2) With the cursor on one of the four control fields at lower left,
press ENTER to snap the next AAT turnpoint to the point
- on the current courseline (from leg start through your location),
- half way from your current location to the back of AAT area
If this would result in a point not in the area it just beeps.
After snapping the TP, the task is recomputed and the stats
message above is automatically displayed.
- Add Discus 2c 18-meter polar
- Formatting improvements (leading ":" on minutes time in many locations)
- Bugfix: Start and Finish lines (and sectors) stay oriented w/respect
to the nominal AAT area centers, not the dragged turnpoint location...
- Bugfix: ENTER on the scroll arrows while in AAT-drag mode does not
re-center map; now it snaps the turnpoint location as above
- DBparse bugfix (for USB adapter only, does not affect SN10 software)
- NOTE: FP traps enabled for 2.35 production release
Return to top.

- Enable on "SN10 Options  1" page (check "MapAlt")
- On map "+" symbol marks an alternate in range, "-" marks an alternate out of range, and "U" marks an alternate whose elevation is not known.
    CAUTION: As always, the alternate calculation doesn't know about the ridge between you and the alternate !
- Select an alternate at top left: 0 is none, 1 is closest, etc.

- IGC file: fill in CID (competition ID), not GID
- Initial (Rudi #4) integration
- Internal minor C++ reorgs and cleanups

- Additional polars: Blanik L-33, AMT-200 Ximango, DG-1000
WARNING: A USB-to-serial adapter with Windows XP will not work for the V2.27 SN10 software update!  To update to V2.27 you must use a PC with a "real" (standard) serial port.  The SN10 PCLink application does work AOK with a USB-to-serial converter as this USB related problem only affects the SN10 software update utility.

MS Internet Explorer adds an unwanted .TXT suffix to the file name.
  HL still requires that the 8.3 filename have type NDB.
- Bugfix: Mac users, SL/SL32 tolerates Mac line terminator in HEX files.
- Bugfix: FPM units display error (showed incorrect sink rates for polar

  selection on the option page, then before each task set the radius on
  the Flight Recorder page.
- FAI sectors available on moving map (set Competition Rules = FAI)
- FAI sectors available for datalogger turn notification (set Notice=FAI).
  VolksLogger task declaration: SN10 will detect an attached Volkslogger,
  and (if you wish) automatically declare your flight in the logger.
  NOTE: Requires Volkslogger firmware version 173 or later.
  Enter your task in the SN10 **and THEN** plug in the VolksLogger, and
  reply Yes to "Do you want to declare your task in the Volkslogger".
  NOTE: you must respond within a few seconds, or this won't work.
- Extended help on altimeter or QNH shows altitude in flight level
  and English units, for easier work with ATC and airspace boundaries.
- GPS mark creates point in database called "GPSmark" (landing,turn).
- Alternates "Go Direct" marks the point of "Go Direct" as "GPSmark",
  and shows this point as start of leg to alternate. This gives a
  courseline on the map, plus meaningful distance right and left of
  course as you fly to the alternate. You'll see GPSmark crossed-off
  on the task page after you "Go Direct" to an alternate.
- Change: By popular demand, "Dist to go" before you start a task now
  shows only task distance (and no longer includes distance to start point).
- Set "Start Time Interval" to 0:00 to suppress warning message:
  "You have 10 minutes remaining in your start time interval"
- In an NDB file, the map data origin (map home point) is now allowed to
  differ from the site's home point by up to 300km.
- Add Genesis II polar (Idaflieg/Johnson hybrid polar).
