Serial Broadcast Mode Configuration with a Tree Network

--A tree network using multiple radios is very flexible; many repeaters and servers 

can be combined to cover vast areas and get around hills or buildings. In the other networks, the wireless "hops" are minimized. In this sys­
tem, you can "hop" as much as you need to, but the trade­off is speed. This is the slowest of the network layouts. For larger tree networks, 
we recommend avoiding serial broadcast mode and switching the radios to MultiHop Data Radio mode.

IMPORTANT: Star and tree topologies in serial mode use a Broadcast radio technique. Broadcasting allows for many 
radios and larger, complex systems but also introduces a small chance that a data packet can be lost. These network 

topologies require the control system to automatically resend missing data packets. Most control protocols (like Mod­

bus) will work fine. Other serial stream-based protocols may not be as tolerant and should only be used with point-to-

point topologies.
