(Jared Yates) ________________________________ Message 1 _____________________________________ Time: 10:38:13 PM PST US Subject: AeroElectric-List: GNS430 Communication Voltage- 14v or 28v? From: Jared Yates I'm wiring my 14-volt panel, which includes a Garmin GNS430, non-WAAS "legacy" version, and I am looking for advice from someone who is familiar with the development timeline. I have an older hard copy of an installation manual that says that the aircraft power on the P4002 (Communications) connector must be at 28 volts. I noticed in the more recent 430W installation manual that only the "A" high power units have this 28-volt requirement. Does anyone know when the change happened? For instance, do all of the old non-waas units have this 28-volt communication requirement, or is there a mod that makes some of the non-w units (hopefully mine) 14-volt capable? The placard on the unit says that it is up to mod level 5, and I have a list of all of the various service bulletins that have been applied to it, in case any of that might help. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
