Wiring: Use twisted shielded pair (Connect Air W221P-2544 or equiv.).
Daisy-chain and tie shield to earth ground at one point only.
The polarity of the signal must always be maintained throughout the network.
Always c to + and – to –. The shield connection must be
continuous throughout the entire network and must be connected
to earth ground at one (and only one) point.
Use Belden 8471, NEMA Level 4, or Echelon-approved equivalent wire.
Since the LonWorks communication wiring is polarity insensitive, no polarity
must be observed when making connections via the unshielded twisted-pair
wiring.
Note: The N2 Bus can use either solid or stranded wires of the following types:
3-wire twisted cable, 2 twisted-pair telephone cable, or two twisted pair
with a shield.
The wiring is polarity sensitive.
The polarity of the signal must always be maintained throughout the network.
Always c to + and – to –. The shield connection must be
continuous throughout the entire network and must be connected
to earth ground at one (and only one) point.
