Guardian issue

just got my system this week (V4 logger, osd pro, gps and guardian).
after i connected every thing i can't get the guardian to work i arrtificial horizon is not moving and i noticed that even when i connect only the guardian to logger and to the USB the Firmware control window says guardian not connected ... any chance i am doing some thing wrong and it is not a bad unit???

One more thing i would like to use the latest alpha with the ppm mode will it work with the guardian? if i will ever get it to work..

guytzoler, sorry to hear about your issue. First, does the OSD Pro show up under the firmware control page, when it is connected to the eLogger? If so, that indicates that both the eLogger and OSD Pro are working correctly, and we can narrow down the issue to the Guardian.

If so, s it possible that the wire harness for the Guardian is plugged backwards into the eLogger (or OSD, depending on where you have it connected in the chain)? If you could post a photo of your connections, that would help to verify. Also, does the Guardian's LED blink when connected?

Thanks for the help first of all
the OSD and eLogger both shows up and can update firmware and works great i have already made my own OSD screen and checked it out side for GPS FIX all looks good
i have tried 2 different chain connection.
1. eLogger->Osd->Guardian
2. eLogger->Guardian->Osd
on both cases did not got any kind of life sign from the Guardian no lights and the osd said stabilizer disconnected.
i have also tried these 2 chains under 2 different firmware versions
1. eLogger v 1.19 and OSD v2.62
2. eLogger v 1.15 and OSD v2.52
right now i have installed it into my bixler without the Guardian for Friday morning so i can't take photos but trust me for that this is not a connection issue i am know my way around electronic equipment and i have gone all over the manuals.
i have bought this from TowerHobbies last week (for any warranty issues).
if you have any other idea i will be happy to try it i have a lot of spare time from Sunday.

Thanks for the updates. It does sound like there is an issue with your Guardian. If you could open a ticket with us at, and link to this thread, we will get it resolved for you asap. Since the other pieces are working fine, we should only need to replace the Guardian. Sorry for the trouble!

I'll make sure your ticket is followed up on if it hasn't been already. March/April are always really busy due to the good flying weather all the sudden.
