3. Network Topologies  

Topology refers to the shape of a network, or the network's layout. How different nodes in a 
network are connected to each other and how they communicate is determined by the network's 
topology.  The CL4424s support a Point-to-Point and a Point-to-Multipoint network topology. 

3.1 Point-to-Point 

 

A point-to-point system is a simple arrangement consisting of just two CL4424s - a Server and a 
Client.  Sometimes referred to as a wireless bridge, a point-to-point link replaces a single 
communications cable. A point-to-point link might be used to connect a PLC to a remote 
monitoring station.

3.2 Point-to-Multipoint 

Point-to-Multipoint systems have one base station, or access point, that controls communications 
with all of the other wireless nodes in the network.  This allows for the creation of a wireless 
network consisting of multiple nodes. By programming each CL4424 with a network specific 
Channel Number and System ID multiple networks can be created as shown below.
