RF450 Spread Spectrum Radio
3.6.4 RF450 Operation Mode Setting
The Operation Mode option designates the method FreeWave transceivers use
to communicate with each other. FreeWave transceivers operate in a Master-
to-Slave configuration. Before the transceivers can operate together, they must
be set up to properly communicate.
In a point-to-point configuration, Master or Slave mode may be used on either
end of the communication link without performance degradation. When
setting up the transceiver, remember that a number of parameters are controlled
by the settings in the Master. Also, radio network diagnostics can only be
accessed at the Master radio. Therefore, we suggest you deploy the Master on
the communications end where it will be easier to access.
For a datalogger PakBus network, the multi-point radio modes should be used.
For other configurations, the Operation Mode will need to be set through the
Settings Editor tab.
3.6.4.1 Operation Mode Description Point-to-MultiPoint Master
This mode designates the transceiver as a Master in multi-point mode. This
mode allows one Master transceiver to simultaneously be in communication
with numerous Slaves and repeaters. A point-to-multi-point Master
communicates only with other transceivers designated as point-to-multipoint
Slaves or point-to-multipoint repeaters.
Point-to-MultiPoint Slave
This mode designates the transceiver as a Slave in multi-point mode. This
mode allows the Slave to communicate with a multi-point Master. The Slave
may communicate with its Master through one or more repeaters.
Point-to-MultiPoint Repeater
This option allows the transceiver to operate as a repeater in a multi-point
network.
Point-to-MultiPoint Slave/Repeater
This option allows the transceiver to operate as a repeater and a Slave in a
multi-point network. The radio will repeat packets sent across the network as
well as use the active interface. Choosing this setting effectively sets the
operation mode to multi-point repeater and sets the Slave/repeater mode.
Repeaters Used Setting
In a multi-point network, it is critical to transmission timing to configure this
parameter correctly. This box should be checked (set to 1 in Settings Editor) if
there are any repeaters in the network. It should be left unchecked (set to 0 in
Settings Editor) if there are no repeaters present.
This parameter should be set to the same value in all transceivers in a multi-
point network.
