IP920 Operating Manual: Chapter 4 Configuration 27
Network Type: defines radio network topology.
*Point-to-Multipoint (PMP) network
Point-to-Point (PP) network
Peer to Peer (P2P) network
Everyone to Everyone (E2E) network
In a point to multipoint (PMP) network, the master unit broadcasts packets
to every remotes/repeaters in the network. Destination address is set to
65535 automatically on the master for PMP network.
In a point to point (PP) network, the master only communicates with one
remote whose unit address matches the destination address of this master
unit. The destination address needs to be set properly on the master unit of a
point-to-point network.
A peer to peer (P2P) would allow remotes in the network to communicate
with each other. The destination address should be set to the unit address of
its peer
An Everyone to Everyone (E2E) would allow all remotes in the network to
communicate with each other. The destination address is set to 65535 on all
units inside an E2E network.
Roaming Address: Only valid on remote/repeater units. This
parameter defines which upstream unit this unit should synchronize with. If
a particular unit address is set, this unit will only try to synchronize with
that specific unit.
Unit address 1 stands for the Master in the network;
Other unit address (2~65534) specifies an upstream repeater;
Broadcast address 65535 tells this unit to find an available upstream unit
(master or repeater) and synchronize with it. This unit will look for another
unit in case of synchronization loss.
Repeater: can only be seen on a master unit. It tells the master if
repeater(s) exists in a radio network.
Optimization: can only be seen on a master unit. It tells the master to
optimize system in three different ways, High Throughput/Balanced/Low
Latency.
High Throughput
*Balanced
Low Latency
When throughput is the priority in an application, High throughput
should be chosen; when a system has short packets and latency
requirement is the priority, Low Latency should be selected;
otherwise, the selection of Balanced is a compromise of throughput
and latency.
