If your Ronin 2 experiences issues that sound like:
Often users find the only solution they come across is rebooting the Ronin, Receiver, or unplugging the Receiver to resolve this issue.
You may be experiencing S.Bus Signal Corruption.
Sometimes the Ronin 2 can switch modes/settings because of a signal loss/interference between there receiver and the Ronin that occurs in line with the cable that connects the two.
This failure has been observed to have several different causes.
The Ronin 2 has several S.Bus channels.
A few of the channels control Heading Modes and Profile. If the values in these channels changes even 1 bit for one packet, the gimbal will change modes or profiles.
In other digital communication methods, there is a checksum or other digital validation scheme to prevent corruption. S.Bus does not have this. Nor has DJI adopted a method to prevent this (such as a time delay).
If the connection between the receiver or the gimbal jostles the digital pin, then the data can be corrupted.
If the connection between the receiver and the gimbal jostles the power or ground pin, then the receiver will reboot instantly, and the data can be corrupted.
If the data is corrupted, the mode or profile will change.
It is not necessary to reboot the gimbal or receiver because these settings are directly changeable in the wheels.
Within the Inertia Wheels, under Menu > Output > Ronin Settings, you can toggle these modes directly. This will save you from having to reboot/unplug anything.
To address the failure permanently.
A) Confirm you have this style of Receiver to R2 cable.
B) Try a backup cable.
C) Clean the contacts on the Ronin 2 and on the Receiver with electrical contact cleaner to ensure no dust or debris is creating interference.
D) Jostle the cable lightly with your hand. If it repeatedly causes this issue, then something between the Receiver and the Ronin 2 is likely damaged. We have observed damaged cables, damaged Receivers, and even damaged Ronin 2 pins.
E) Confirm you have set up the gimbal according to the suggested settings chart. One setting that is often overlooked is that we suggest both the Default Profile and User 1 be identical profiles. That way if the profile does change it will not impact the operating or gimbal performance.
