2.6 Cable Selection
The HART bus is a balanced (differential) 2-wire interface running
over a Shielded Twisted Pair (STP), Un-shielded Twisted Pair (UTP), or
Ribbon cable. How to decide a cable type, cable length, and terminator in
the HART bus network, please refer to the following table.
Note: The AWG means a standard method used to measure wire. The
numbering system works backwards from what people would think, the
thicker (heavier) the wire, the lower the number.
