PWM1\~PWM13 are Dshot and PWM capable. However, mixing Dshot and normal PWM operation for outputs is restricted into groups, ie. enabling Dshot for an output in a group requires that ALL outputs in that group be configured and used as Dshot, rather than PWM outputs.
If servo and motor are mixed in same group, make sure this group run lowest PWM frequency according to the servo specification. ie. Servo supports Max. 50Hz, ESC must run at 50Hz in this group.

However, bi-directional protocols which include telemetry, such as SRXL2 and FPort, when connected in this manner, will only provide RC without telemetry. To allow CRSF and embedded telemetry available in Fport, CRSF, and SRXL2 receivers, the Rx6 pin can also be configured to be used as true UART RX pin for use with bi-directional systems by setting the [BRD\_ALT\_CONFIG](https://ardupilot.org/copter/docs/parameters.html#brd-alt-config) to “1” so it becomes the SERIAL7 port’s RX input pin. With this option, [SERIAL7\_PROTOCOL](https://ardupilot.org/copter/docs/parameters.html#serial7-protocol) must be set to “23”, and: * PPM is not supported. * SBUS/DSM/SRXL connects to the Rx6 pin, but SBUS requires that the [SERIAL7\_OPTIONS](https://ardupilot.org/copter/docs/parameters.html#serial7-options) be set to “3”. * FPort requires connection to Tx6 and [SERIAL7\_OPTIONS](https://ardupilot.org/copter/docs/parameters.html#serial7-options) be set to “7”. If Telemetry doesn’t work, try set [SERIAL7\_OPTIONS](https://ardupilot.org/copter/docs/parameters.html#serial7-options) = 135. * CRSF also requires a Tx6 connection, in addition to Rx6, and automatically provides telemetry. Set [SERIAL7\_OPTIONS](https://ardupilot.org/copter/docs/parameters.html#serial7-options) to “0”. * SRXL2 requires a connection to Tx6 and automatically provides telemetry. Set [SERIAL7\_OPTIONS](https://ardupilot.org/copter/docs/parameters.html#serial7-options) to “4”. Any UART can be used for RC system connections in ArduPilot also, and is compatible with all protocols except PPM. See [Radio Control Systems](https://ardupilot.org/copter/docs/common-rc-systems.html#common-rc-systems) for details. – **ArduPilot Relay(PINIO)** * Camera-1 and Vsw On by default * Make sure 2 cameras are set with identical video format, both PAL or both NTSC. \# GPIOs * PD10 PINIO1 OUTPUT GPIO(81) //9Vsw pad power switch * PD11 PINIO2 OUTPUT GPIO(82) //Camera switch \# RCx\_OPTION: RC input option * 28 Relay On/Off * 34 Relay2 On/Off * 35 Relay3 On/Off * 36 Relay4 On/Off e.g. * RELAY\_PIN 81 //9Vsw GPIO * RC7\_OPTION 28 //Relay On/Off, Use CH7 of Transmitter to switch 9Vsw * RELAY\_PIN2 82 //Camera switch GPIO * RC8\_OPTION 34 //Relay2 On/Off, Use CH8 of Transmitter to switch camera The configured feature will be triggered when the auxiliary switch’s pwm value becomes higher than 1800. It will be deactivated when the value falls below 1200. Check the pwm value sent from the transmitter when the switch is high and low using the Mission Planner’s Initial Setup >> Mandatory Hardware >> Radio Calibration screen. If it does not climb higher than 1800 or lower than 1200, it is best to adjust the servo end points in the transmitter.
