To con�igure:
1. Select the Settings button on the Main page.
2. Select the Controller tab at the top of the page. Ensure Serial Protocol is set to PWM.
3. Select a PWM channel to con�igure.
4. Select the desired function.
5. Select the number of states. The number of states will depend on the type of switch that
is being mapped on the �light controller. For a three-position switch, the number of states
will be three.
6. Assign functions to the available states for each signal.
7. Program the �light controller to provide signals to the Aux Out ports for the P1, P2 and/or
P3 connectors on the Accessory Cable.
The Duo Pro R accepts standard PWM inputs for the R/C industry, 3.3-5vdc, 50Hz. LOW =
1ms/20ms, MID = 1.5ms/20ms, HIGH = 2ms/20ms.
Frame Sync: PWM channel 3 (Accessory Port Pin 4) can be con�igured to provide a 3.3vdc
output during image save operations for time synchronization with other external devices.
For Still images, the signal is high during the capture of individual frames. During Video and
Timelapse the signal is high for the duration of capture. Frame Sync is not available as an
input to the Duo Pro R. To enable Frame Sync, select "Frame Sync" as the function for PWM3
through the UAS App.
MAVLink: Many UAS �light controllers support the MAVLink serial protocol to provide an
interface with external components. The Duo Pro R can be con�igured to use this bus to
capture available telemetry data provided by GPS, altimeter, accelerometers, etc. This data
is saved as standard EXIF metadata in Still Image �iles (JPG & TIFF). This data is not saved to
Video �iles as there is no current standard for doing this. Metadata is accessible through
standard photo editing applications, �ile explorers, and suggested mapping applications.
