My project is a simple one, relative to the panels I see being built here. But, I have some questions about the components "communicating".
I have an EDM350 engine monitor that can receive data from the Aera660 GPS to display fuel data. The EDM manual just says to connect the RS232 data lines to the GPS but does not specify a protocol. The AV30's can use NMEA as does the GPS so will I assume the engine monitor will use that protocol as well?
For physical connections, I have been looking but cannot find info on that directly. A friend has a Garmin manual and it kind of shows that to make 2 connections to one pin in a DSub connector, I can just solder a connection onto the pin wire, a little back from the pin, and then cover in heat shrink? Since my 15 pin dsubs don't use many wires, they should accommodate such a connection. Or is there another method for doing these connections? I would think I need to maintain shielding, so guessing it needs to be contained within the dsub housing? Or am I worrying too much about the short piece of exposed unshielded wire on a data line? Attached is my wiring diagram, still in development....
Any input/critique/suggestions appreciated. Thanks.
