Appendix 2: Technical Information Pro Version 

We recommend the hardware from, simparts which is optimally matched to our software.This makes it particularly easy to build the home cockpit.

Connection of buttons and switches

Unless the CAN bus solution from simparts is used, the EC 135 Pro offers the option of connecting all important buttons and switches via standard USB joystick controllers such as the BU0836. To do this, the software generates special custom commands that can be assigned to the individual ports of the controller. In order to influence the performance as little as possible, we differentiate between different types of switches. These are optimized in such a way that as few contacts as possible are closed in normal flight conditions.

• Button. As usual, the contact is closed as long as the button is pressed.
• ON switch. As usual, the contact is closed when the switch is in the on state.
• OFF switch: The contact is closed when the switch is in the OFF state.
• 3 pole switch (e.g. ENG switch). The corresponding switches usually have two each one closed contact in the extreme positions. Accordingly, you need two ports of the joystick controller. The software provides two custom commands for each of these switches.

When wiring the panels, it is important to know which switches are of which type so that they are installed in the correct orientation.

More information will be coming soon.
