REP-1 Connections and Ratings

Electrical connections:

A basic repeater connects to the net-

work at the end of the run. A repeater

can extend the distance of the network

or can add more nodes to the system.

If a basic repeater is in place, the

original network ends at the REP-1 and

is terminated with a 120 ohm resistor.

Basic Repeater - Style 7 Wiring

The new repeated network begins at

the REP-1 and also has an end of line

resistor. In a Style 4 network the

second half of the REP-1 is not used,

so it has both sides terminated. For

Style 7 networks use both halves of

the REP-1. For additional wiring infor-

mation see the REP-1 Installation

Instructions, P/N 315-092686.
