Terminate LinkConnect Control Wiring
Unison control stations communicate with the Paradigm Architectural Control Processor using the
Echelon LinkPower network (LinkConnect). LinkConnect is based on Echelon LonWorks with
LinkPower bidirectional protocol, and uses one pair of wires (data+ and data-).
Termination is available for up to twelve home runs of LinkPower data runs utilizing Belden 8471 cable
(or approved equal) plus one 14 AWG ESD drain wire when the data cable is not installed in grounded
metal conduit.
LinkPower wiring is topology-free and polarity independent. Wiring may be any combination of bus,
star, loop, and home run. The total combined length of LinkPower wire run cannot exceed 1,640 ft
(500 m), with a maximum distance of 1,313 ft (400 m) between any two communicating devices.
Without a repeater, no device may be more than 1,313 ft (400 m) away from the Architectural Control
Processor.
Standard interoperability requires that there should be a maximum of only one station repeater
between any two LinkConnect devices. This means that only one Repeater Module, whether a
Paradigm Station Repeater Module (P-REP) or a Paradigm Dual Station Repeater Module (P-DREP), may
be used per Paradigm Architectural Control Processor (P-ACP). Each individual topology-free LonWorks
network can have no more than 62 LON stations with a repeater, Station Power Module,and Paradigm
Architectural Control Processor.
1:
Pull Belden 8471 (or approved equal) control wiring into the ERn4 enclosure through the conduit
opening previously prepared.
2:
Strip 3/16” (5 mm) of insulation from the ends of each wire pair.
3:
Remove the LinkPower connector (labeled LON)
from the top right I/O board.
• Notice the LinkPower connector is labeled to
indicate that the connector is split between two
segments, allowing six station wire home runs
per segment. This is effective only when a
Paradigm Dual Station Repeater module (P-
DREP) is used. With the standard Paradigm
Station Repeater module (P-REP) you may
connect up to twelve station home runs connect to the single control segment.
4:
Loosen the terminal screws for as many wire pairs you are terminating. Keep in mind that the
connector is split into two segments when used with a Dual Repeater Module. Be sure to
terminate each wire pair to the correct segment.
5:
Insert each white (typical) wire from the pairs into an “A” terminal on the connector and tighten
the screw firmly to secure the wire into the connector.
6:
Insert each black (typical) wire from the pairs into an “B” terminal on the connector and tighten
the screw firmly to secure the wire into the connector.
Note:
Wire tie down locations provided on rear panel.
Note:
All low voltage control cables must run in separate conduit from power wires.
Note:
When utilizing a Paradigm Station Repeater module (P-REP) or Paradigm dual station
repeater module (P-DREP), terminate the affected LON segment(s) and associated
auxiliary power wiring to the top right I/O board in the ERn4 enclosure.
