3.0 Configuration
3.2 Point to Point Network
In a point-to-point network, a path is created to transfer data between Point A and Point B, where Point
A may be considered the Master modem and Point B a Slave. Such a PTP network may also involve
one or more Repeaters (in a store-and-forward capacity) should the radio signal path dictate such a
requirement. Point to Point is enabled by setting register S133 to 1 (
ATS133=1, Network Type
).
A PTP configuration may also be used in a more dynamic sense: there may be many Slaves (and Re-
peaters) within such a network, however the Master may have its ‘Destination Address’ (S140) changed
when required to communicate with a specific Slave.
3.2.1 Operating Modes / Unit Types
In a Microhard Point to Point Network, three unit types or operating modes are available: the Master,
Repeater, and the Remote. The
Masters
role is to provide network synchronization for the system,
which ensures all units are active and able to communicate as required. The Master controls the flow of
data through the system; all data passes through it. The diagram below shows a unit configured as a
Master.
