Garmin X96 Wiring
This will be serial as well. You'll need the cable from Garmin to connect this.

Note from the Forums January 21st, 2008
If your D100/D180 EFIS has battery backup, you can assure continued operation in the case of aircraft power failure as follows:
- Split the blue wire from the Garmin x96 (Garmin Serial Tx) - Connect the split to pin 19 on the D37 connector on the D180
The EFIS SHOULD ignore this system as long as there is power to the HS34, but will use it if aircraft power fails to receive GPS data from your handheld.
Forum Note Update: Feb 22 2008
In some cases having the x96 hooked directly to the EFIS causes flickering, which they are investigating. Until they get it fixed, you may wish to install an on/off switch between the x96 and the EFIS (not interrupting the signal to the HS34).
