All necessary electronics is built into the top of the stick and only the wires from the control
tube to the interface unit need to be used. This solution makes the installation very easy.
Additionally two shielded cables are used for speed command key and PTT.
Do not forget to set the speed command input setting to TASTER (see Chapter
5.1.12.1).
The original stick grip should be removed and replaced with the new one. On the top of the
new grip there are 9 push buttons. An additional button positioned on the front side is for
climb/cruise change over. Both the PTT and climb/cruise buttons are wired separately. All
remaining buttons are connected to the built-in microcontroller and only four wires should be
connected to the RS485 system bus. A very small interface printed circuit board connects
four wires coming out of the stick to the 485 System bus.
After installation there is no special setting required on LX9000 side as the remote
stick will be automatically detected.
