Network Topologies; Point-To-Point (Ptp) - Microhard Systems Nano IP Series Operating Manual

5.0 Network Topologies

The IP Series may be configured to operate in a number of different operating modes and par-
ticipate in various network topologies.
Note: This section describes radio network topologies in general and includes examples of cor-
responding Radio Configuration settings. Refer to section 6 for further detailed information re-

5.1 Point-to-Point (PTP)

Take this important
fact into consideration
In a Point-to-Point network, a path is created to transfer data between

network topology.
network may also involve one or more Repeaters (in a store-and-forward capacity) should the
radio signal path dictate such a requirement. (Note that a Repeater may also concurrently func-
tion as a Remote, i.e. it may pass data to and from an attached device(s).)
A PTP configuration may also be used in a more dynamic sense: there may be many Remotes
(and Repeaters) within such a network, however the Master may have its ‗Destination Address'
changed as and when required to communicate with a specific remote unit.
An example of a basic PTP network consisting of two IP Series is on the next page.


Configuration options are based upon the chosen Operating Mode of the unit: se-
lect the Operating Mode first.

The DESTINATION UNIT for the MASTER is the UNIT ADDRESS of the REMOTE,
and vice versa (noting that the MASTER's Unit Address (not visible) is preset, and
must remain as, ‗1').

For a PTP system, RETRANSMISSIONS on a MASTER is not as critical a setting
as it is in a Point-to-Multipoint (PMP) system.
