Please do read the user manual first to get familiar with buttons/operations. * Use a 5-pin to 3 bin cable to connect the SBUS ports on the receiver to the SBUS port on Pixhawk. While pressing the F/S button on the receiver, power it on. It will go into binding mode. * Power on the transmitter. Press `Menu` button, and then press `Page` button to navigate to `SETUP` in page 2/12. * Set `Mode` to `ACCST 16`. * Go to `RxNum`, select `[Bnd]` out of `01 [Bnd] [Rng]` and press the scroll button to start binding. Wait for a couple seconds, and the indicator of the receiver will be flashing in green. * Restart/power the receiver. If the indicator is in constant green, it is paired successfully. * Lastly, it is recommended to set up `failsafe`, following the instructions on user manual. ### Battery Consumption * An experiment is conducted to test how much time the 850mAh 4S battery can support Jetson Xavier NX onboard computer. The experiment started at 3:42pm and the voltage was logged together with timestamp as follows. The computer is running in max performance mode with full payload (using Zed camera). It was prompted constantly that "System throttled due to Over-current." ``` // time voltage 3:42 16.6v 3:45 16.4v 3:50 16.0v 3:53 15.7v 3:56 15.6v 4:04 15.2v 4:08 15.1v 4:12 15.0v 4:15 14.9v 4:20 14.8v ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
