3. Quick Start
This section is intended to serve as a “primer” enabling you to quickly build a
simple system and see how it operates. This section describes in four steps
how to set up a pair of RF400s in a direct connect, point-to-point network. We
recommend that you do this before undertaking field installation. For
additional help on point-to-point networks and for help on creating point-to-
multipoint networks, refer to Software Setup Section 5.
