This is the one with the orange and black display that shows bar graphs for EGT, CHT, etc. It has a data logging capability, but the interface requires their cable, which I don't have: https://www.jpinstruments.com/shop/pc-interface-cable-for-edm-700-edm-800-and-edm-760/ This looks like something that I could make out of things I have laying around the shop, vs spending $40 plus shipping. Does anyone have one sitting around that they could do some continuity testing on? If the little plug only has two conductors, I would guess that there must be two pins on the serial end that they are connected to. JPI also offers a box that takes the serial from that cable and writes to a USB drive. They charge $200 for that box, and I'd love to see what's in one of those. Another option is to send the unit into JPI, where they will modify it to have a USB interface for $300. And of course there is always the option of just pretending like it doesn't record data, but where's the fun in that? ------------------------------------------------------------------------------------- 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.
