Overview
Developed based on PSDK and a high-performance embedded computer, gPort is an add-on
accessory enabling users to integrate Gremsy gimbals with DJI’s enterprise drone platforms, adding
a new level of efficiency to commercial missions.
This guide shows you how to mount, connect, configure and control Gremsy gimbals (Pixy F, Pixy
WS) to collect images & videos on M300/M200 V2 series using gPort. It also covers steps to set up
your application with DJI’s Drones.

Features
Capturing and live streaming video from DJI drone system
gPort lets your payload (including camera & Gremsy gimbal) communicate with DJI drone's
transmission system to capture and live stream video in real-time as well as provides high quality
video with efficient H.264 encoding.
Gathering data from the Drone and Gimbal to tag your pictures
Controlling and configuring the Gimbal
gPort allows users to control gimbal from remote controller and set gimbal parameters through
the DJI Pilot app during the flight.
Controlling and configuring the Camera
FLIR Duo Pro R
Full alternative for the FLIR UAS App. This allows users to adjust the MSX, IR Color Palette,
Display Video Mode (Visible stream only, thermal infrared IR stream only and a Picture-In-Picture
stream), and advanced settings:
Recalibrate: To maintain optimum performance
Digital Display Format
Recorded Video
IR Format
Still File Type

Radiometry
And more…
Please refer to FLIR DUO PRO R User Guide.
Workswell Wiris Camera
Taking advantage of Wiris protocol supported for Wiris Security and Wiris Pro. Using DJI app
can eliminate the keyboard and display for setting and configuring parameters for the WIRIS camera.
CANBus & UART SDK gives the user option to control WIRIS PRO, WIRIS PRO SC, or
WIRIS Security with simple widgets on the DJI Pilot App.
Record/capture
Muli-camera modes (Ful screen mode, IR only, VIS only, Picture-In-Picture)
Set palette
Set camera zoom
