4. RFCommunicationModes
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, Repeater, Acknowledged or Multi-Streaming)
The following table provides a summary of the network configurations supported.

Point-to-Point
Definition An RF data link between two modules.
Sample Network Profile *
(Broadcast Communications)
Use default values for all modules.
Sample Network Profile *
(Acknowledged Communications)
All Modules: ATAM [auto-set MY (Source Address) parameter] **
ATDT FFFF [set Destination Address to 0xFFFF]
Basic Communication RF Modes Streaming Mode [p37], Repeater Mode [p38]
Acknowledged Communication RF Mode Acknowledged Mode [p
41]
Point-to-Multipoint
Definition RF data links between one base and multiple remotes.
Base: ATMY 0 [set Source Address to 0x00]
ATDT FFFF [set Destination Address to 0xFFFF]
Sample Network Profile *
(Basic Communications)
Remotes: ATAM [auto-set MY (Source Address) parameter] **
ATDT 0 [set Destination Address to 0x00]
Base: ATMY 0 [set Source Address to 0x00]
ATDT FFFF [set Destination Address to 0xFFFF]
ATRR 3 [set number of Retries to 3]
Sample Network Profile *
(Acknowledged Communications)
Remotes: ATAM [auto-set MY (Source Address) parameter] **
ATDT 0 [set Destination Address to 0x00]
ATRR 3 [set number of Retries to 3]
Basic Communication RF Modes Streaming Mode [p37], Repeater Mode [p38]
Acknowledged Communication RF Modes Acknowledged Mode [p
41], Multi-Streaming Mode [p43]
Peer-to-Peer
Definition
Modules remain synchronized without use of a master/server. 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).
