Problem following loss of signal rc with sabertooth 2x12

I’m Eddy, And I need your help…

I installed a 2x12 sabertooth controller in a robot.
It receives the information by an RC receiver.
The problem is, when I turn off the power to the RC transmitter while a command is being executed, the controller does not stop and my robot continues to roll. I tried to switch the dip 6 to “ON” but that doesn’t change anything.
Have you already encountered this problem or do you have a solution?
Thanks again,
Cordially, Eddy.


Welcome to RobotShop community.

We are sorry to hear that you are having trouble with your Sabertooth controller.

Please contact the manufacturer directly to assist you with this issue:

Let us know if you need further assistance.


How are you sending commands to the sabertooth controller? Arduino Uno or something similar?

Keep in mind that shutting the power on the transmitter does not stop the last command sent to the Arduino. If the Arduino has power, it will continue to execute the last command and send signal to the sabertooth motor controller.
