SBUSo for extra servo ports - No output on Cube?

Hey guys,

I’m trying to use the SBUSo port on a Cube to add two digital servos (using an SBUS to PWM decoder).

On one of our two Cubes, there is no measurable output on that port (it’s a cube developers version). Is that a hardware issue or is it possible to completely deactivate the port in Software?

Thanks a lot
