Tim... I've flown mine using the supplied battery, without any issues. I've also performed quite a few ground tests (I use Christmas tree bulbs when doing so) without any problems.
Is there someone who lives near to you who has a TeleMetrum, where you can try their battery? -Kevin -----Original Message----- From: altusmetrum [mailto:[email protected]] On Behalf Of Tim Navickas Sent: Tuesday, April 08, 2014 8:06 PM To: 'Keith Packard'; 'Bdale Garbee'; 'Altus Metrum' Subject: Re: [altusmetrum] Telemetrum Problems Today I connected to the Telemetrum via USB and tried to fire the igniters. On both the Main and Apogee firing the Telemetrum resets and goes through the startup sequence. I assume this means I cannot use the supplied battery to fire igniters. I am also assuming that others have used the supplied battery to fire the igniters. Does this mean I have a bad board now? Is there any other kind of troubleshooting I can do? I really do not want to use this only as an expensive tracker and have to use 2 other altimeters.

TeleMetrum v1.0 units had some extra RF sensitivity due to a missing capacitor as described here: http://www.gag.com/bdale/blog/posts/RF_Immunity.html Have you been trying to fire igniters via USB? Or just over the RF link? If it's over USB, then RF can't be involved as there won't be any transmissions from either end. Does the TeleMetrum reset when you try? It would beep out the startup sequence again if it were. If it's only over RF, then you might send some pictures of the installation as we may be able to suggest ways to reduce the RF problem. > I have always flown this as a data logger and tracker but this will be > the first time I have used it for dual deploy.

I'd definitely agree with this plan; fly nothing that you aren't sure about. -keith _______________________________________________ altusmetrum mailing list [email protected] http://lists.gag.com/mailman/listinfo/altusmetrum _______________________________________________ altusmetrum mailing list [email protected] http://lists.gag.com/mailman/listinfo/altusmetrum
