What does Hamming distance (6) used in NK-2.4Y mean?

Invented in 1940s by Richard Hamming of Bel Labs, Hamming codes are used in error detection and correction during transmissions where signal bits in a codeword are corrupted by noise. They are a form of linear correcting codes. The value of this Hamming distance determines the error correction ability with a minimum value of 1 (no error detection) to higher values eg. 2,3..6 etc. which can detect and correct more errors.

For reliability, the Hamming feature in the NK-2.4Y can detect these bit errors (but ONLY detect, not correct) and discard the signal to prevent false outputs occurring, especially when using multiple NK-2.4Y units in one area.
