Network Topologies in MultiHop Mode

Cable Replacement Configuration for Point-to-Point Networks--In this simple cable replacement application, the radio system knows all data 
originating at one end must be transmitted to the other end. This allows the radio system to automatically correct for transmission problems 
and it also provides the greatest throughput. This is the fastest configuration.

Cable Replacement Configuration for with Repeaters--In this simple cable replacement application with a repeater radio, the radio system 
still knows all data originating at one end must be transmitted to the other end. In this application, no serial devices are connected to the 
repeater(s). The system still corrects for transmission problems, but it takes time to repeat the message. The network delay is double that of 
a system with no repeater.

MultiHop Mode (Star Network)

--In this more complex star topology, the client radio at the center of the network can communicate with many 

server radios. A common example would be a PLC at the center communicating with many remote I/O systems. The star topology is slower 
than a point-to-point network but faster than a tree network.
