This guide will focus on connection setup with various commonly used receivers and ESCs.<\/p>\n\n\n\n

Connectors<\/h2>\n\n\n\n

The below figure shows the available connectors on the Nexus FBL controller.<\/p>\n\n\n

Nexus Connectors<\/figcaption><\/figure>\n<\/div>\n\n\n

Receiver, Receiver Telemetry as well as ESC Telemetry use Serial ports. The Nexus has 5 Serial ports available on different connector types. Below table summarizes all of them.<\/p>\n\n\n\n

Receiver connections<\/h2>\n\n\n\n

RotorFlight supports a number of Receiver protocols like Crossfire (CRSF), Frsky F.PORT, Futaba S.BUS, Spektrum DSM, SRLX 2, etc.<\/p>\n\n\n\n

The Receiver can be connected to any of the Serial ports highlighted green in the below picture.<\/p>\n\n\n

\n
\"\"
Nexus Receiver ports<\/figcaption><\/figure>\n<\/div>\n\n\n

NOTE: SBUS port does not receive power from USB. Ports A\/B\/C and DSP receive power from USB. So it is recommended to connect the receiver to those ports as you can test the receiver when connected over USB without requiring extra power source over the Servo Ports.<\/p>\n\n\n\n

In the below picture, Receiver RP3-H is connected to Port-A. Denoted by Serial Rx. The connection cable is provided with the RP3-H receiver.<\/p>\n\n\n

\n
\"\"

In the below picture, Receiver Frsky R-XSR is connected to Port-A. Denoted by Serial Rx. The receiver port adapter cable is provided with NEXUS controller. <\/p>\n\n\n

\n
\"\"

In the configuration screen choose “Serial Rx” for the port you have connected the receiver to. In the above examples we have connected the receiver to Port A.<\/p>\n\n\n

\n
\"\"

ESC Throttle connection<\/h2>\n\n\n\n

Connect the Throttle cable from the ESC to the ESC port on the Nexus controller.<\/p>\n\n\n

\n
\"\"

ESC Telemetry connection<\/h2>\n\n\n\n

Rotorflight 2 supports a number of ESC telemetry protocols like Scorpion, OMPHOBBY, YGE, Hobbywing, etc.<\/p>\n\n\n\n

The ESC telemetry signal can be connected to any of the Serial ports highlighted green in the below picture.<\/p>\n\n\n

\n
\"\"

Motor RPM connection<\/h2>\n\n\n\n

The Motor RPM signal from ESC or RPM sensor should be connected to the RPM port.<\/p>\n\n\n

\n
\"\"

Swashplate Servo connection<\/h2>\n\n\n\n

First configure the correct servo configuration for the servos that you intend to use. This is done in the Servos tab.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

Connect the swash-plate servos to S1, S2 and S3 ports on the Nexus according to your helicopter’s swash-plate mechanical layout. Below is an example of popular servo layouts. For more servo layouts refer to Rotorflight wiki<\/a>.<\/p>\n\n\n
