Volkslogger - No Log Download Success "data -transfer ready!"

FINAL CONCLUSION... SERIAL CHIP DEFECTIVE ON VL

I think the serial chip is defective. Tested unsuccessfully downloading using SeeYou Connection Wizard with another old PC using a regular serial port.. Now, I don't even get the he "DATA-TRANSFER READY" message on the VL even with the USB converter on various PCs and notebooks. Apparently the 115200 bps speed for data transfers no longer works reliably.

My VL still works ok at 4800 bps driving my SN10B (Just tested again this afternoon in my glider).

Based on Murphy's Law... my VL will probably fail on the first day of the Region 9 contest at Moriarity (1.5 weeks away). Symptoms seems to be pointing in this direction with a 15 year old unit. I'm going to buy a Nano and wire it up before I leave...

Hey Walt - Get a PowerFLARM if you haven't already done so !
Logger works great, SN10 can declare task into PowerFLARM.
Hope that helps,
See ya, Dave

PS: 2.38 is now released:

Hi Dave,

I've already got PowerFlarm. It drives LK8000 on the Vertica V2 which can also declare tasks on the PF. I've been using igc files from the PF for the last half dozen flights and they validate fine on OLC. Want to keep full logger redundancy each driving their own flight software. Needed to replace the VL with another logger that has validation for all flights. PF doesn't isn't good for National or World records.

BTW, ten pilots out of 14 flew PF at our local Central California Soaring Contest and v3.0 worked just fine. PCAS seems more sensitive. FLARM sensitivity worked great in and around gaggles.

Dave,

Can the SN10B declare tasks to an attached (wired RS-232 interface) Nano data logger?

Hi Walt,

The SN10 can send task declarations to Volksloggers and FLARMs, but not to
Nano's or anything else.

POST FINAL CONCLUSION...MY VL WORKS FINE NOW!

Long after the original post, I re-visited my VL download problem by using a different but identical USB Converter (XS-882 from USConverters.com). Low and behold, my download to a PC from the VL worked perfectly! So, my VL is OK... I'm the idiot for not checking all the components/cables that could have caused the problem. Moral to the story is... Check all possible connectivity problems before blaming hardware on your logger. It's hard to test these USB Converters since so few devices use serial connections. But, you can do a loop back test with the right type of connectors: http://www.usconverters.com/download...bleshooter.pdf I wasn't able to do this because those connectors were not available to me.

BTW, USConverters.com, is a great company to work with. After returning my XS-882 with a letter asking them to test it and replace if faulty.. they simply mailed me a new one free of charge! Now, I have a VL, set of cables and a USB Converter for sale in case anyone out there wants to buy my setup.
