I have a lynxmotion ssc-32u that I have used for a couple years with no issue. I’m using Trackskull program to create my routines. Suddenly it all stopped working.
The board is powered with 12v 3A adapter. I was going through Servo Controller to Cat6 breakout board to connect to my animatronics. controlling 9 servos
I have power on the board,
boots up to baud 115200(both the GreenA and Red B leds come on)
PC acknowledges the Device has attached,
I see power on the remote breakout board, via the cat6 cable
After launching the trackskull software it connects using setting of Controller:MiniCCS,COM5,115200. on servos 0,1,2
Once I connect and use my joystick I can see the RX1 LED flickers and the A Green LED flickesr but nothing happens with the servos.
I tried my other preprogramed setting using 4,5,6 and 8,9,10 and none of those work either.
removed all servo connections from the remote board and went strait from port 0 to a servo and still get no reaction.
Installed the SSC-32 servo sequencer - Connects COM5,115200 but can’t get any response from that either.
Just purchased a new board and it acts the same way.
Any help would be much appreciated
Hi rtink,
Can you share some picture of your original and new SSC-32U ?
This is to verify any jumpers and connection that might have been missed.
You said you are using a 12V supply but most RC servos are operated at 5-6V, do you have a separated power source for your servos or you have special 12V servos ?
The SSC-32U can share power for Logic and Servo but if you have 5-6V servos they will get burned at 12V.

Let us know,
I’m using a setup I got online, they had links to all the parts. But i’m now wondering if my power supply accidently got swapped with another I had. looking into that now. will get back to you. Thanks for the help
Ok, keep us posted about the results.
My power supplies got swapped. So im now on 6v 3A. Have pulled out a new unused servo attached to port 0.
On old board. Verified all setting are the same. I have never changed anything on the old board. Still having the same issue as before. Could there be something with the OS with some recent patch? on win11
Can you provide pictures of the board you are testing so we can verify the jumpers, wiring etc ?
Is the PC you are using the same as before ? If not you may need to install the drivers but I feel like you would not even be able to connect via the SSC-32 Sequencer.
Yes this is the same PC I have used
I’m not quite sure what that mean, can you elaborate on that ?
Regarding your picture, everything seems to be OK.
The power is connected to VS1 and jumpers for VS1/VS2 are present, the servo is also connected right.
What’s the status exactly:
- Are you able to initiate a serial communication in the SSC-32 Sequencer ?
- What’s the Baudrate auto detected in the SSC-32 Sequencer ?
- Is that the Baudrate you are using in your “trackskull” project ?
- Is you servo moving when using the SSC-32 Sequencer ? If not, do you have a way to test if your servo is still operational ?
All the best,
I’ll just stick with the SSC-32 sequencer for this issue.
The SSC-32 looks to be set at 115200, when I power up both the Green A and Red B LED are on.
When the Servo Sequencer starts up it sees the SSC32
Com5,115200, Auto Found lights on. Input A shows around 40
On the SSC32 the RX1 and A LEDs blink
have a new HS-425BB servo on Port 0, verified the black lead wire is on the ground pin.
When I move the slider on Servo0, the RX1 and A LEDs blink more rabidly but the servo does not move.
Tried all servo ports 0-3
Thanks for the detailed explanation.
Have you tried both your SSC-32U ?
Can you manually set the baudrate to “9600” and then select your COM port (5 probably) ?
Also, once communication is initiated, place you finger on the Input pins, it should trigger the A B C D inputs.
- Do you have any other system like a RC system that could be used to test the Servo ?
- Do you have extensions between the Servo and Board that might be reversed ?
Looks like I got something.
I started all over again with my new board. reset everything again and this time it started to work. Tried various ports and everything looks good.
With that said looks like I blew my ss32 board and all my servos.
Thank you for all your patience
Quite sad to know for the servos but glad you were able to get it working again.
