CIMA approval document and user instructions for the MLR
MLR downloader software
This is used to download the data from MLR SP24XC's which are in CIMA logger mode to IGC format required for flight analysis.
- Download the software.
- Unzip the file somewhere on your computer.
- Double click on MlrDownload.exe or at a shortcut pointing at it.
- Set the location where the eventual output files will be saved.
- Plug in the MLR and switch it on.
- The MLR should download automatically.
- Note that it is MUCH easier and faster to download MLRs when the ID of each one has been saved,
and a task window has been set. See Annex 2 of the CIMA approval document for full instructions.
Normal MLR firmware changer software
In championships, all MLRs must be in 2 second or 5 second logger mode. Any pilot found in posession of
a MLR in 'free flying mode' will score zero and could be disqualified.
Use this software to switch a MLR between free flying mode, 2 second flight recorder mode and 5 second flight recorder mode.
- Download the software.
- Unzip the file somewhere on your computer.
- Double click on MLR LOAD VL-FF.exe or at a shortcut pointing at it.
- Set Receiver type to SP24XC TRACK_2 (for 2 second interval logging = 4h 32 min endurance.)
- Set Receiver type to SP24XC TRACK_5 (for 5 second interval logging = 11h 20 min endurance.)
- Plug in the MLR to a serial port. (Note that only some USB-Serial converters work).
- Click the button to start loading the MLR firmware.
- Note that in 'free flight' mode the serial port connection is closed by default and must be opened in the MLR's settings menu before this
software will work.
- VERY IMPORTANT Do NOT disconnect the MLR until the process has finished or the logger could be rendered useless for ever!
Nuclear MLR firmware changer software
If the display on a MLR shows only
WRONG CHECKSUM WAIT PROGRAM then the ROM is corrupted. It is possible to achieve this by
disconnecting data cable when altering the internal software. The 'nuclear' software can often be used to recover a 'dead' MLR - if this doesn't
work then the MLR is truly dead.
- Download the software.
- Unzip the file somewhere on your computer.
- Double click on MLR LOAD V1.12.exe or at a shortcut pointing at it.
- Set Receiver type to SP24XC FFVL
- Plug in the MLR to a serial port. (Note that only some USB-Serial converters work).
- Click the button to start loading the MLR firmware.
- VERY IMPORTANT Do NOT disconnect the MLR until the process has finished or the logger could be rendered useless for ever!
- When finished, go to the MLR's settings menu and open the serial port so you can load the normal 2 sec or 5 sec logger firmware as above.
