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.
