Hi,

first of all, you should connect an receiver to your RX2SIM. There are two examples described here: https://www.cgm-online.com/rc-flight-sim...next-usb_e.html (section RX2SIM).

- Switch on your transmitter.
- First of all, we define a new model. Select therefore the 'LNK' button.
- Then select the 'MODEL SEL.' menu and press 'RTN'.
- Select 'NEW' and press 'RTN'.
- Use the presets TYPE: AIRPLANE, WING: NORMAL, TAIL: NORMAL
-> Now the new model is defined. You can rename it to 'neXt'.

Then you bind the receiver to your transmitter as described in your manuals. Set the input mode of the RX2SIM: https://www.cgm-online.com/rc-flight-sim...next-usb_e.html (section RX2SIM).

- Then select the 'FUNCTION' menu in your transmitter.
- There are already functions for Aileron, Elevator, Throttle and Rudder defined. It's a good idea to disable the trim functions by defining '--'.
- Scroll down to page 2. The SE switch is already defined as GEAR.
- Then move to the 'VPP' row and assign there for example the 'SB' switch.
- Now You can check the output by pressing the 'U.Menu/Mon.' button on your transmitter (servo output).

Start the neXt simulator, press esc and change to settings > input device tab. Now take a look at the input monitor window. Each function should come out on one channel or button. Now you can start the calibration and follow the instructions there.

This is for all models.
