Spirit System

Hello Tomas.
I would like to connect a GPS sensor to the Spirit RS.
I need an EX bus for this, which is only available on E1 / E2.
I connected the telemetry from the YGE controller to E1 and only connected the RPM signal to the middle pin on E2.
How would it work best, will I probably need an Expander EX or will it work without it?

If you will connect GeoLink then it is wired to the SAT port.
In this case no additional port is needed.

But for other GPS sensors you can use EXT port if it connected with JETIBOX/Sensor telemetry.
