ACCESS protocol and supports OTA functions 900MHz/868MHz long-range with low latency Enhanced and design 6 standard servo connectors (default PWM channel) Switchable CH5/CH6 into S.Port/SBUS Output channels Support S.Port / F.Port (Configurable in OpenTX / FrOS menu) Signal redundancy function External battery detection Detachable Ipex1 connector antenna The R9 SX is the enhanced version of the R9 Slim series of long-range capable receivers. It adds 3-pin servo connectors with 6 full PWM channels and utilizes the dual-antenna design. The light-weight protective shell has a Multi-use 6-pin plug to bring you additional functions like signal redundancy, telemetry feedback, external battery detection and more. Flexibility is a key feature of this receiver. The 6 PWM channels can be converted to 4 PWM channels with the additional Ch5 and Ch6 can be configured as an alternative S.Port and SBUS outputs to the 6-pin port. The enhanced design proves to be more , and in conjunction with the latest ACCESS firmware, the two are now synchronized and we are to unlock the true potential of the ACCESS protocol.
