While trying to configure my Dynamixel motor, I've tried to use Arduino ax12SetRegister function.

I've decided to write:

ax12SetRegister (1, 3, 5);

1 was the current ID of motor.
3 as the register location.
5 was the new ID value.

And here is where everything went wrong. Now my ID is -1. I cannot access it. Do you know a fix? I cannot enter RoboPlus, and I am not sure even that would help. I cannot find it with DynaManager now, as well. I've changed the baud to 16, so 115200, but it was also saying -1...
