Communication
Module
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 shield. The wiring is polarity sensitive.
The polarity of the signal must always be maintained throughout the
network. Always connect + 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 L W communication wiring is polarity insensitive, no polarity
ON ORKS
must be observed when making connections via the unshielded twisted-pair wiring.
Wiring: Use twisted shielded pair (Connect Air W221P-2544 or equivalent).
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 connect + 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.
