To configure:
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 configure.
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 flight 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 flight 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 configured 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 flight controllers support the MAVLink serial protocol to provide an
interface with external components. The Duo Pro R can be configured 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 files (JPG & TIFF). This data is not saved to
Video files as there is no current standard for doing this. Metadata is accessible through
standard photo editing applications, file explorers, and suggested mapping applications.
