Installation Instructions
Model REP-1
Network Repeater Module
INTRODUCTION
The Model REP-1 from Siemens Industry,
Inc., is an MXL module that permits the
user to extend the distance of the MXL
RS-485 network as well as the distance of
the NIM-1R RS-485 network. The REP-1
also supports both Style 4 and Style 7
wiring.
The MXL network uses an RS-485 inter-
face for its network wiring. The RS-485
supports up to 32 nodes on each pair of
wires (See Note below).
Note: A node is any location where
the network wires are con-
nected to the screw terminals
of an MXL System module.

signal makes it possible to add more nodes
to the system.
