4. RF Communication Modes
The network configurations covered in this chapter are described in terms of the following:
 Network Topology (Point-to-Point, Point-to-Multipoint or Peer-to-Peer)
 RF Communication Type (Basic or Acknowledged)
 RF Mode (Streaming, Multi-Transmit, Repeater, Acknowledged or Polling)
Note: Please see the DigiMesh chapter for additional information on networking features.
The following table provides a summary of the network configurations supported.
* Assume default values for parameters not listed. Prs do not t addressing implementations.
** AM (Aut
o-set MY) Command must be issued through a terminal program suh as the one rporated in the
X-CTU 'Terminal' tab.

Peer-to-Peer
Definition
RF modules remain synchronized without use of master/server
dependencies. Each module shares the roles of master and slave.
MaxStream's peer-to-peer architecture features fast synch times
(35ms to synchronize modules) and fast cold start times (50ms
before transmission).
