Analysis Software for PalmOS, PocketPC and MacOS

Petri Kuikka and Tapio Linkosalo are authors of LOLO1/LOLO2 analysis software for PalmOS. Visit theirs website and try that neat utility. (12/12/2003)

Daniel Szkudlarek made LOLO Viewer ver. 1.1 for Pocket PC OS (1MB ZIP) . Please be aware this tool is not already supported by Daniel neither by me. (25/09/2006)

After some initial troubles Chuck Auerbach is running my software even on MacOS 10.X using VirtualPC and Windows emulation (and my USB adapter). It works!

HW Hack

If you want to activate second set of longer sampling rates follow these instructions

  • 2-nd set gives you 0.2sec (28min), 1.0sec (2h:16min), 2.0 sec (4h:32min) and 6.0sec (19h:36min) sampling rates for A2 Standard version
  • 2-nd set gives you 0.2sec(1h:52 min), 1.0sec (9h:4min), 2.0 (18h:8min) and 6.0sec (54h:30min) sampling rates for A2 BF version
  • Using sharp scalpel open small window in shrink tube on red marked position
  • Using solder bridge two soldering points (see picture)
  • Cover window by tape

This hardware modification will not void your warranty. Anyhow don't repeat soldering on mentioned points several times, you can damage printed board circuit.

Questions&Answers

Q Does the unit keep its recorded data when A2 is powered OFF?

A Yes! Until you will clear memory. However you can't clear memory seletively i.e. only some logs. You can clear only whole memory.

Q Can you change the sampling rate without loosing the data? For example, could you do a flight at the 0.1 second rate, then change to the 0.5 second rate and do another flight, and then download the data from both flights at the end?

A Yes! No problem, just sampling rate must be switched over (using DIP switch) when A2 is OFF.

Q In LOLO/LOLO RACE there were only 10 ON/OFF blocks. Is there any limit in A2/L2?

A No! There is no blocks-flights (ON/OFF) limit in A2/L2.

Q What kind of interface on PC do I need ?

A You need RS 232 interface e.g. serial port (also known as mouse port; COM1-5). If your PC has ONLY USB port you can buy USB/RS232 adapter. There are many on the market, be carefull many of them doesn't work properly. You can buy from me USB/RS232 adapter wihich 100% works with A2. Sure it works also with other RS232 devices.

Q A2 LED is just off, no blinking. Power is ON. It doesn't log. What 's wrong with my A2?

A Your A2 memory is full. Clear it!

Q It's possible to adjust the sensibility? When I power on my A2 just on the table values oscillate around 0 or even during time is drifting to bigger +/- altitudes.

A Used technology A/D converter etc. is price/performance compromise. If you want to measure altitude with 0.5m resolution (and better), always there will be some noise. Its like water surface, looks smooth but never is totally smooth. You should be aware A2 is VERY sensitive atmosphere/altitude converter, if there is weather change, sure air pressure is changing (especially during longer timed logs), when you have A2 on the table and your wife will smash with doors (So silly thing, so expensive!! :)) you will see it in altitude log. To eliminate all these effects would increase complexity, size and price, sure.

Q It's possible to calibrate my A2 precisely?

A Yes and No. Every A2 is calibrated to fit ordinary aplication precision. We tested some A2 pieces in Czech Airlines laboratories, in pressure camber for full size airplains altimeters. Testing staff was amazed by precision of this tiny device! On the other hand there was still room to modify pressure/altitude formula to reach exeptional precision. Its clear I can't make such calibration on every piece, its extremely expensive. Anyhow you can modify pressure/altitude formula to reach requested precision on your own. Its opened system.
