Brief Description: Connect Dynon EMS and EFIS DSAB's Together
Both the Dynon EMS and EFIS units need 9 pin D-Subs connectors on the DSAB wires (Dynon Smart Avionics Bus) so they can connect to a serial port on a PC for software updates and also so they can connect to each other. The EMS unit already had the D-Sub installed on the harness from SteinAir. However, I had to wire up the connector for the Approach Systems harness for the EFIS. The two were then connected together via a null modem and male changer that I purchased from Radio Shack. These wires are relatively long so they can be disconnected and pulled down into the cabin to hook up to my laptop via a serial to USB converter for future software upgrades so for now I just coiled them up and temporarily zip tied them to the left subpanel rib.
