I purchased the Pro combo Ronin SC that included the external focus motor and followed the few directions provided to get it set up, but no matter what I try, I'm unable to have the focus motor connect to the gimbal/focus wheel down on the hand grip. Both are just blinking red still. Has anyone else had a similar issue?

I'm working with a Sony A7rii – the camera control (start/stop recording) works when attached so the cables seem to be working fine

I found that if I used the wrong cable it didn't work for me. Make sure you use the multi-spitter cable. Then when you turn it on, double tap the button on the focus wheel to calibrate.

Hmm, I'm using the multi splitter – When you turned it on after connecting, did the lights still blink red? I double tapped the button on the focus wheel and it didn't do anything

Blink red is means No Found Motor.
Type-c Camera is connect to middle connector above the  multi splitter.
And on side Type-c is connect the Moter, Other side Type-c connect  the hand grip.
Tye again ?

solid yellow: found moter ,but no calibration.
single yellow blinking: being travel calibrated.
solid green:   found moter with travel calibration complete or found camera.
single green blinking:  set a point.
double green blinking: set a-b point complete.  Now rotate the wheel, traval will from a-b or b-a point only. If you click buttom again,two point will be delete. The led will be solid green.

When I turn it on it gives me a solid yellow to indicate it needs calibrating.

Don't connect the camera to the multi-splitter and start it up and see if you get at least the solid yellow light. If that doesn't work, check the switch at the bottom the focus wheel, and make sure it's on S-Bus, not on Can. Then turn it all on again and see if it works for you.

Yeah, that's how I have it connected – the labels are pretty clearly labeled
(TO SONY) Multi - that's plugged into my Sony a7rII
(TO FOCUS MOTOR) USB-C - that's plugged into the focus motor next to the camera lens
(TO GIMBAL) USB-C – that's plugged into the gimbal arm just under where the camera is mounted

Weird, yeah no luck – I've tried all kinds of stuff. Turning things on in different order, plugging them in in different order, switching to both S-Bus and Cam and still stuck with the red light. Tried without the camera plugged in as well

I feel like your cable is defective. I’ve tried different USB cables myself and none of them work but that multi-splitter one. I have no idea what is special about that cable but it’s the only one that works for me.

Have you tried the other side of the grip to see if the connections on that side might make a difference? That’s about all I have left to suggest. Obviously contact support and see about getting a new cable.

I have a similar issue with a a6500 and the sony 50 /1.8 lens. I have tried to use both the CAN and the SBUS selection. I also tried the unplugging of the camera and still no use. Sometimes the SC motor goes to a solid green but when I turn the wheel nothing happens. If I double click to try to go to calibration nothing happens. I called support in the morning and they did not provide any help, just pointed me to this page and said watch teh video, what video ?

Yeah, that's what I'm thinking – defective motor or cable

I sent them a message yesterday so I'll see what happens

thanks for your help!

hahaha yeah, there was zero information anywhere for the external focus motor other than the small pamphlet in the box

I was looking all over for a video when I was installing it

I have the same issue with my Ronin SC. The Focus control keeps blinking red. I did the firmware update but no success in being able to calibrate the focus motor. Any idea what could be?

Hey, did you figure out the solution to your problem? I just set up a Tonin-SC with the red blinking right when you turn on the device. Thanks!

Hi , can anybody tell me if the problem with the[b] Ronin S connecting a HDMI feed to an Ninja V has been solved. I sent mine back after getting so annoyed with it, but thinking of the SC if the problem was fixed.
I'm using a Nikon Z6 and Atamos Ninja V.
Problem, when Nikon Z6 is connected to the Ronin S using the USB cable, the live feed to the Atoms Ninja V doesn't work.
Please can someone help. Cheers.

Just fixed this problem after two hours of trouble shooting. I just got the Ronin SC and assembled it out of the box. I’m using a Panasonic Gh5 and canon glass. The focus wheel and motor went through different iterations of blinking Red. Sometimes slow and then also a fast double blink. I powered down the device and then turned it back on while I pressed the multifunction button on the focus wheel, this set it into a “needs to be updated mode” I then proceeded to go through the update process and it booted up/calibrated focus motor perfectly.

I am having a similar issue with my SC and the follow focus.  There are three issues as far as I can tell.

One is that the while the wheel sees the motor (light is yellow) it will not calibrate.  On the off chance that pressing the button causes the light to blink, the motor light then begins to blink red.  When I move the wheel, the motor turns in very short 'spurts' (not much distance and very quickly).  

Also when I am connected to my GH5, the screen 'blinks' about once a second. I am using PC Tether as my connection type.  Latest GH5 firmware.

Lastly, the app is always offering the latest Firmware update even after a successful update.  In the Firmware tab the "Firmware Version' is N/A.  Wheel is 2.2 and Motor is 1.0.

Any help on this would be appreciated.

Hello, I recently got the Dji ronin sc but ever since I turned it on! The pull focus wheel blinks red! I I’m only trying to pull focus from my camera set to manual, and not trying to use a focus motor. Online it shows this works but hasn’t been a good experience. I’m not sure if it’s a defective focus wheel. Does Dji replace this?
