Sets a new joystick button number to an encoder center push-button connector. Each encoder pair has a center push-button that can be mapped by J-PORT. These push-buttons can be assigned to any joystick button number between 1 and 200. They are internally connected via a virtual connector. There are four of these with the following connector numbers:
| Instrument Encoder | Internal Connector | Default Joystick Button Number | Internal Functions |
|---|
| COMM | 1 | 1 | YES |
| NAV | 2 | 2 | YES |
| ADF | 3 | 3 | NO |
| XPDR | 4 | 4 | NO |
Notes:
- COMM and NAV encoders have internal functionalities (e.g., swap frequencies) that will always perform these functions regardless of remapping. However, these can still be re-mapped to other joystick buttons if needed.
- ADF and XPDR encoders do not have internal functionalities but can also be mapped to any joystick button number.
See RNS Features in the beginning of this chapter for more detail.
