I have a question for anyone who had done this install to a GNS-430W. The only wires that connect to the 430 are the RS-232 in and out ports. The wire is shielded.
The directions show a shield ground to the shield ground block (symbol "s" in triangle) and at the 430 end the shield goes to aircraft ground (standard aircraft ground symbol).
There is a detailed instruction about attaching a wire to the shield and also adding a boding strap from the Flight stream connector shell to the aircraft.
So if I understand this right, at the Flight stream end I attach a wire to the shield then use a ring terminal to attach it to the DB connector shell (all metal) then use another ring terminal and 10AWG bonding strap to connect the DB shell to someplace on the aircraft.
On the 430 end the shield gets attached to the wire and then to aircraft ground, is this the same as the ground block on the back of the 430. Right now each shielded wire going into the 430 has a ground wire attached to the shield via a solder sleeve and these wires attach via a small pin into a plastic block that attaches over a metal blade that is part of the back shell of the 430, the connector slides over the metal blade giving contact to the back shell.
So, do I run the shield from wire to this same block or to an air frame location near by?
If I can use the shield block on the back of the 430, where to I find the connector pin, my local Garmin Dealer who is doing the software update on the 430 does not carry them.
Thanks for any help. I can't wait to load flight plans from the iPad into the 430!
Cheers
