    The XTend RF Module supports three different network topologies: point-to-point, point-to-multipoint and peer-to- peer.

    Point-to-multipoint networks Acknowledged mode. Point-to-multipoint networks This following section provides the RF communication type and RF mode for XTend RF Module point-to-multipoint networks. Definition Point-to-multipoint means a network with RF data links between one base and multiple remotes. Sample network profile (Broadcast communications) Assume the default value for all parameters that are not in this list.

  • Page 64: Basic Rf Modes

    In Peer-to-peer networks, RF devices remain synchronized without the use of master/server dependencies. Each device shares the roles of master and slave. Digi's peer-to-peer architecture features fast synch times (35 ms to synchronize devices) and fast cold start times (50 ms before transmission).

  • Page 65: Acknowledged Rf Mode

    Basic communications includes two sub-types: • Broadcast. By default, the XTend RF Module communicates through Broadcast communications and within a peer-to-peer network topology. When any device transmits, all other devices within range receive the data and pass it directly to their host device.
