1.1 Introduction
DJI™ SDR Transmission is a wireless transmission system featuring DJI SDR video
transmission technology. DJI SDR Transmission features modes such as SDR mode and
Wi-Fi mode, oering you a more cost-eective monitoring solution. Control mode and
Broadcast mode are supported using SDR signal transmission. In Control mode, you can
connect one transmitter to two receivers, allowing seamless auto frequency hopping
and dynamic bitrate adjustments, which ensure ultra-long-range transmission and strong
interference resistance. In Broadcast mode, you can connect one transmitter to an
unlimited number of receivers, allowing multiple receivers to monitor within a close range
simultaneously. Wi-Fi mode allows one transmitter to connect up to two mobile devices at
the same time, which is suitable for temporary monitoring.
In addition to connecting to the monitor via HDMI and SDI ports, DJI SDR Transmission
also supports connecting mobile devices via USB-C port or Wi-Fi and monitoring via the
Ronin app. The Ronin app also provides professional monitoring assistance tools and
supports functions such as gimbal control and camera control. You can log in to your
accounts to sync the footage to the Filming app.

In Control mode, you can connect one transmitter with up to two receivers, experiencing
a longer video transmission distance and a stronger interference resistance. Control
mode enables seamless auto frequency hopping and dynamic bitrate adjustments,
meeting the demands for high-quality transmission and scenarios where one transmitter
is connected to two receivers. Two-way communication via the headset is enabled
between the transmitter and the receiver. Each transmitter can only communicate with
one receiver.
Linking
Control mode is enabled by default. Follow these steps to link the transmitter and the
receiver:
1. Slide down on the receiver home screen, tap Connection Mode and select CTRL.A or
CTRL.B to enter the linking status.
2. Press and hold the link button on the transmitter to enter the linking status and start
linking. Tap Cancel to terminate the process at any time during the process.
Once connected, slide up on the home screen of the transmitter or receiver to select the
appropriate channel. This action can also be completed by sliding down on the receiver
home screen, tapping SDR Channel, and then selecting the appropriate channel.
• When a transmitter and two receivers are connected in Control mode, place the
receivers at least half a meter apart to avoid uplink interference.
• Minimize obstructions between the transmitter and receiver for the optimal
transmission signal. Elevate the transmitter or the receiver if necessary.
5.2 Broadcast Mode
Introduction
In Broadcast mode, you can connect an unlimited number of receivers to a transmitter,
but compromises on transmission range and bitrate when compared with Control mode.
