Serial Interconnects

In wiring my panel, I needed to build a drawing of all the serial interconnects. In the process, I provisioned it for what I believe would work with a GDL-90 ADS-B receiever.

I also have many things that share a common sources.. For example, I have 3 if not 4 items that take NMEA from the G496 and also about the same from the GPS data from the Chelton GADAHRS.

I devised a way to use "DB" type connectors as a poor mans serial buss. I'll take the source side and daisy chain together the numbers needed, and then on the destination side, the only common pin will be the shield. This should allow easier swapping as needed between the various serial devices. Hopefully, I won't have to swap, but just in case, this method seemed to be the most simple to utilize to facilitate all the sources and destinations.

Anyway, back to the drawing. You can get it from my web site - here

It is color coded for the various interconnects... It also shows the locations of the serial busses and reflects a panel design using CPC connectors to facilitate simple removal of the entire panel if needed.

Hope this helps someone, I know it certainly will help me.
