Group,
A friend of mine who is very good with electrics (ham, did electronics in the coast guard, does circuit level troubleshooting) was looking at my panel diagram and recommends against running a serial output from one device to several others without an isolator.
For example, the aviation serial output on the GNS430W is connected to the EFIS and Portable GPS.
Far and wide this is minimized by each device having multiple inputs/outputs, but in some cases there isn't enough serial ports and it doesn't seem reasonable to output the same information twice.
So here are the questions:
1. Is it acceptable to split serial outputs?
2. Is there an isolator I can buy?
3. What do certified aircraft use to get around this problem?
Thanks,
schu
