For those who have been there done that.....
I am connecting a Garmin SL30 and a Garmin 696 to a Dynon HS34. The Garmin manual calls for a 3 wire shielded serial connection: Tx, Rx, Serial Ground, plus shield connections to ground at both devices (at the SL30 and the other device, in this case the HS34). The HS34 has no serial ground connection. So do I ignore this wire on the SL30, or do I connect the serial ground to ground at the SL30 only? How about the shields? Connect at both ends as the Garmin manual says, or just at the SL30? Or no shields at all as the Dynon manual says?
For the 696 connection, the Dynon manual shows no shields, so I assume this is ok. Correct?
Thanks and Happy New Year!
