ERn Wall-mount Installation Manual
Install a Paradigm Repeater or Dual Repeater Module
Both repeater module types may only be utilized in the top module slots of the ERn4 rack enclosure.
The Paradigm Station Repeater (P-REP) module extends the system station bus length by 1,640 ft
(500 m) 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 ft
(1,000 m) through two separate topology-free Echelon segments (each supporting 1,640 ft (500 m) of
additional LinkPower station wire each) and adds support for up to 30 additional stations.
