Paradigm Repeater Module Installation

The Paradigm station repeater (P-REP) module extends the system station bus length by 1,640
feet (500m) and adds support for up to 30 additional stations.

The Paradigm dual station repeater (P-DREP) module extends the system station bus length 3,280
feet (1,000m) through two separate Echelon segments, supporting 1,640 feet (500m) of additional
LinkPower station wire each, and adds support for up to 30 additional stations.

Both repeater module types may be utilized in the top module slots of the ERn4 rack enclosure.

The following table lists the recommended control wire types used in a typical Unison installation
and the maximum wire runs allowed.

ETC Setup Guide

Terminate LinkPower (LON®) Control Wiring

Unison control stations communicate with the Paradigm architectural control processor using the
LinkConnect station communication bus from the architectural control processor to the stations.
LinkConnect is based on Echelon
pair of wires (data+, data-).

Throughout this document, LinkConnect is referred to by the protocol it uses, LinkPower.

Termination is available for up to six home runs of LinkPower (LON) 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, you can install
your LinkPower data runs in any desired combination of bus, star, loop, and home. The total
combined length of LinkPower wire run cannot exceed 1,640 feet (500m), with a maximum distance
of 1,313 feet (400m) between any two un-repeated communicating devices. Without a repeater, no
device may be more than 1,313 feet (400m) away from the architectural control processor.

Standard LON interoperability requires that there should be a maximum of only one repeater
between any two LON 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.

Note:

Note:

Step 1: Pull Belden 8471 (or approved equal) control wiring into the ERn4 enclosure.
Step 2: Strip 3/16” (4.8mm) of insulation from the ends of each wire pair.
Step 3: Remove the LinkPower connector (labeled LON) from the I/O board

All low voltage control cables must run in separate conduit from power wires.

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.

Notice the LinkPower/LON connector is labeled to
indicate that the connector is split between two LON
segments, allowing three station wire home runs per
segment. This is effective only when a Paradigm dual
station repeater module (P-DREP) is used. With the
