5.0 Network Topologies
5.3 Peer-to-Peer (P2P)
P2P mode is used for communications between pairings of Remote modems,
e.g. Slave 12 can exchange data with (only) Slave 14, Slave 6 can exchange data with
(only) Slave 7, etc.
There are no specific factory default settings for P2P modems.
To establish a basic P2P network:
Master
•
enter into Command Mode
•
load the &F1 factory default settings
•
change the Network Type (S133) to 2
•
change Packet Retransmissions (S113) from 5 to 0 (increase from 0 if re-
quired)
•
save the change using the AT&W command
•
go online with the ATA command
Slave 1
•
enter into Command Mode
•
load the &F2 factory default settings
•
change the Network Type (S133) to 2
•
change the Destination Address to 3 (to be the UA of Slave 2)
•
save the change using the AT&W command
•
go online with the ATA command
Slave 2
•
enter into Command Mode
•
load the &F2 factory default settings
•
change the Network Type (S133) to 2
•
change the Unit Address (S105) to 3
•
change the Destination Address to 2 (the UA of Slave 1)
•
save the change using the AT&W command
•
go online with the ATA command
The Master will broadcast (actually ‘re-broadcast’) the data incoming to it from both Slaves to
all (2) Slaves; one Slave’s data has a destination being the other Slave and vice versa.
A P2P network
requires a Master
modem.
The data being
transmitted from one
Slave to another in
P2P mode is
transferred via the
Master.
