System Configuration Example
Local Centralized (Stack) Configuration
A network system can be configured using several tens of devices centralized using stackable hubs.
Local Configurations with Long-distance Distributed Segments
Basic network with a specific controller in a remote location, or a network that is near high-voltage power lines
or a source of noise interference can be split into two segments, with optical repeaters connected between
segments. This configuration enables a long-distance network with superior noise resistance.
