Performance
This parameter changes the logic polarity for digital inputs, the digital outputs, and the relay outputs.
When this parameter = 0 the digital outputs are in push-pull mode.

Serial comms
When this parameter = 1 either the high-side drive (negative logic polarity) or the low-side driver (positive logic polarity) is disabled.
This allows outputs to be connected in a wire-ORed configuration.
