FAQ
General
What status indicators does DJI SDR Transmission 2 have?
There is one status indicator for system voltage. A fast-flashing red light indicates insufficient voltage, while a green light indicates normal voltage.
Does DJI SDR Transmission 2 support channel quality monitoring?
Yes. A signal quality bar graph is displayed on the Channel Dashboard of the transceiver and in the DJI Ronin app. Taller bars indicate better signal quality. A channel in green indicates good channel quality, while a channel in red indicates poor quality.
What should I pay attention to when using DJI SDR Transmission 2 in high-temperature environments?
Ensure the environment is well-ventilated, avoid blocking any air vents, and avoid exposure to direct sunlight.
Does DJI SDR Transmission 2 support monitoring using a smartphone or tablet?
Yes.
1. A smartphone or tablet can connect to the transceiver (RX) through a USB-C to USB-C or USB-C to Lightning cable*. In this case, the signal is transmitted via SDR for enhanced stability and reliability.
2. For details on smartphones and tablets compatible with the DJI Ronin app, refer to the Ronin App Compatibility List on the Downloads page.

Does DJI SDR Transmission 2 support third-party antennas?
No. Additionally, the antennas on DJI SDR Transmission 2 are non-removable.
Can DJI SDR Transmission 2 be used simultaneously with other wireless devices, such as wireless microphones?
When the transceiver auto-hops to a 2.4GHz channel or a 2.4GHz channel is selected manually, there may be interference with other wireless devices, including wireless microphones. In this case, manually selecting a non-2.4GHz channel is recommended. When selecting a channel, you can check the center frequency of the channel on the transceiver's main interface to confirm whether it is on the 2.4GHz frequency band.
What batteries does DJI SDR Transmission 2 support?
NP-F series batteries. Please note that due to differences in battery capacity and battery life, the actual runtime may vary.

Tips
How do I troubleshoot if the device does not power on properly?
When the transceiver is connected to a stabilizer:
1. Check whether the connection is correct. You can refer to the diagrams in the Quick Start Guide.
2. Check whether the connection cable is the Multi-Camera Control Cable provided with the stabilizer, as third-party USB-C cables may not support power supply.
When using NP-F batteries for power supply:
1. Check whether the battery voltage is sufficient, as low voltage may prevent the device from powering on properly.
When powered via the USB-C port:
1. Check whether you are using a power adapter that supports the PD protocol*. Non-PD power adapters might not supply power correctly. For details, please refer to the PD Adapter Compatibility List on the Downloads page.
* A PD power adapter with an output of 65 W or above is required.

How do I troubleshoot if the monitoring screen is not displaying correctly?
1. Check whether the transceiver (TX) and transceiver (RX) have successfully established a wireless connection. Successful connection information should be displayed on the main interface of the transceiver (RX).
2. On the transceiver (RX), check whether the video stream is being transmitted properly. If it is, video resolution, frame rate, and bitrate should be displayed. If these details are not showing properly, check the video status icon on the transceiver (TX)'s main interface to ensure it is normal.
3. Check whether the video source output format is supported by DJI SDR Transmission 2:
DCI 4K: 23.98/24/25/29.97/30/50/59.94/60fps

How do I troubleshoot grid-like patterns that keep appearing on the monitoring screen?
Check for wireless channel interference:
1. On the Channel Dashboard, check whether multiple device sets are sharing the same channel. When multiple devices are operating on the same set, make sure to use different channels.
2. Access the Video Transmission Diagnostics screen on the transceiver (RX) and adjust the channel based on the diagnostic results.
Check whether there are obstructions:
Elevate the transceiver (RX) to a higher position or minimize obstructions as much as possible.
Check the physical distance between devices:
There are no distance requirements between transceivers (TXs) of different groups or between transceivers (RXs) of different groups. However, it is recommended to keep a distance of at least 30 cm between a transceiver (TX) and a transceiver (RX) from different groups.
For example, if two transceiver groups are on set (TX-A with RX-A, and TX-B with RX-B), there are no distance requirements between TX-A and TX-B, or between RX-A and RX-B, but it is recommended to keep TX-A and RX-B at least 30 cm apart.
Check for cable-related issues:
If the grid-like patterns still occur when the transceiver (RX) is moved to about 1 meter from the transceiver (TX) and the bitrate on the transceiver (RX)'s main interface continues to fluctuate significantly, it could be a cable-related issue. Consider switching to a different cable.

When should I use the low-latency output feature on DJI SDR Transmission 2?
1. When a monitor supports 4K/60fps 10-bit input but the video source frame rate is below 60fps, enable this feature to ensure the transceiver (RX) outputs at a stable 60fps for smoother monitoring.
2. For low-frame-rate video sources, this feature reduces latency to provide a more responsive live view, helping focus pullers and other crew members respond and adjust more precisely.
