MultiHop Mode with a Tree Network Configuration

—A tree network using MultiHop radios is the most powerful wireless system possible; 

many repeaters and server can be combined to cover vast areas and get around hills or buildings. In the other networks, the wireless "hops" 
are minimized. In this system, you can "hop" as much as you need to. In MultiHop mode, there may be some speed tradeoffs, but it is still 

significantly faster and more reliable than a Tree Topology in Serial Mode.

Packet Routing in MultiHop Data Radio Mode

—In MultiHop Data Radio mode, the client radio first discovers all connected Modbus server in 

the network, then uses the Modbus ID contained in the incoming Modbus message to wirelessly route the packet only to the radio attached 

to the target Modbus server. The packet is then passed via the radio’s serial interface to the Modbus device where it is processed. This is en­

tirely transparent to the user. Direct packet-by-packet routing offers an advantage over broadcast addressing with MultiHop paths because 
each hop in the path can be retried independently in the event of a packet error. This results in significantly more reliable packet delivery over 

MultiHop paths. Modbus IDs 01 through 10 are reserved for server directly connected to the host (local I/O). As such, polling messages ad­
dressed to these devices are not relayed over the wireless link. Use Modbus IDs 11 through 60 for remote Modbus server — devices serially 
connected to an R70 Server or Repeater — allowing a maximum of 50 attached devices.
