Point-to-Point
Definition
An RF data link between two modems.
Sample Network Profile *
(Broadcast Communications)
Use default values for all modems.
Sample Network Profile *
(Acknowledged Communications)
All Modems: ATAM [auto-set MY (Source Address) parameter] **
ATDT FFFF [set Destination Address to 0xFFFF]
Basic Communication RF Modes
Streaming Mode [p28], Repeater Mode [p29]
Acknowledged Communication RF Mode
Acknowledged Mode [p32]
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]

Streaming Mode [p28], Repeater Mode [p29]
Acknowledged Communication RF Modes
Acknowledged Mode [p32], Multi-Streaming Mode [p34]
Peer-to-Peer
Definition
Modems remain synchronized without use of a master/server. Each
modem shares the roles of master and slave. MaxStream’s peer-to-
peer architecture features fast synch times (35ms to synchronize
modems) and fast cold start times (50ms before transmission).
Sample Network Profile *
(Basic Communications)
Use default values for all modems.
