One of the wicked things about the Jeti radio, is being able to use the simulator via wireless. To do this, I bought a Jeti R5 receiver, and installed a servo wire with plug on end into my Pheonix simulator dongle. When you do this the dongle will talk to the R5 receiver over PPM signal.
If you look at the dongle, in this picture. You will see 4 wires,
White from the receiver 3 pin wire is soldered to the PPM output on the Dongle, it’s harder to see but you get the idea.
Red is soldered to the far bottom and that’s 5v Positive from the usb cable.
Black is negative. for power to the receiver wire.
