The Pro-150 has been designed with the simplest possible wiring which is shown in the diagram. The controller cover is not shown in this diagram.
For more information on wiring, the instruction manual is available.
This does not show the display which connects via a 4 core cable to its own connector. It is recommended that the display also be fitted although the Pro-150 will work without.
An auxiliary 6 way connector is also present: initially this is used to program the controller if required. In use, it provides additional (optional) functionality.
The reversing switch shown in the diagram below is optional: if not required the controller can easily be re-programmed to joystick mode (centre zero on the pot).
The above wiring is the same as that for the earlier Pro-120 (and the VTX) so that the Pro-150 can be used as a direct replacement for the Pro-120 in most applications.
