R9MX - Manual

Smart Port (S. Port) is a signal wire full duplex digital transmission interface developed by FrSky
Electronic Co., Ltd. All products enabled with Smart Port (including XJT module, XSR, X6R and X8R receiver,
new hub-less sensors, new Smart Dashboard, etc), serial port user data and other user input/output devices
can be connected without limitations for numbers or sequences at a high transmission speed.
Features
• ACCESS protocol and supports OTA functions
• 915MHz / 868MHz long-range with low latency
• Enhanced and durable design
• Support S.Port / F.Port (Configurable in OpenTX / FrOS menu)
• With inverted S.Port outputs
• Signal redundancy function
• Detachable Ipex1 connector antenna
The R9 MX is the enhanced versions of the previous R9 MM/Mini series long-range capable receivers, equivalent in size and weight
equipped with a robust detachable Ipex1 antenna connector.
The R9 MX takes features from the previous R9 Mini and R9 MM making it compatible with more external devices by providing an
Inverted S.Port output and supporting the redundancy function. Additionally, it retains soldering points to connect 4 PWM channels.
The enhanced design proves to be more durable, and in conjunction with the latest ACCESS firmware, the two are now synchronized
and we are able to unlock the true potential of the ACCESS protocol.
