closed switch would ground the input, and a closed switch would normally be considered active.
This command affects the operation of the LIA, LID, and
polarity is reversed, the operation of these commands is reversed.
By default, the polarity for all pins is set to normal (active low).
This command is saved to global non-volatile memory and is not part of a preset. Its value is saved
each time it is changed. It will retain its value after power-down. Since this command writes to non-
volatile memory, there will be a delay before an acknowledgment is returned.

8.85. LO -- Query or Set Status of Logic Output Pins

This command sets or queries the current state of the logic outputs. There are 20 logic outputs, so an
array of 20 boolean values is required or returned, with the first value indicating the state of the first
logic output, the second value indicating the state of the second logic output, and so on.
If a logic output pin has conditions driving it (via the
override any settings imposed by the LO command.
If a logic pin is masked via the
