Notes

Models: FrSky R9 receivers

R9 receivers must be running ACCST Flex firmware

Only supported on MULTI-Modules which have an SX1276 RF module, e.g. the Jumper T18 Pro Internal 5-in-1 module.

Binding

OpenTX <= 2.3.9

During binding the receiver will be configured to output channels 1-8 on the PWM pins, with telemetry on.

OpenTX >= 2.3.10

When binding an R9 receiver the radio will prompt you to choose the bind configuration. This prompt allows you to configure the receiver outputs, in the same way that it can be configured with physical jumpers placed on the PWM output pins during bind.

R9 Binding

The selection you make determines which channels will be output on the PWM pins of the receiver, and whether telemetry is on or off. The remaining channels will be output on the SBUS port.

For Example:

Ch1-8 Telem ON will output the radio channels 1-8 on the receiver's PWM pins and channels 9-16 on the SBUS port, with telemetry enabled. This configuration could typically be used on a model with servos connected directly to the receiver.

Ch9-16 Telem ON will output the radio channels 1-8 on the SBUS port and 9-16 on the receiver's PWM pins, with telemetry enabled. This configuration could typically be used on a model with a flight controller connected to the SBUS port and accessories (such as a camera gimbal) connected to the PWM pins.

Refer to your receiver documentation for more information.
