Install a Paradigm Repeater or Dual Repeater Module
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 topology-free Echelon segments (each
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 only be utilized in the top module slots of the ERn4
enclosure.
