remote and repeater radios, and forwards it to
the network operations center.
In any given network, there is only one
master.
Repeater A repeater is used to extend the range of the
master radio. Several repeaters can be
chained together to span long distances.
The repeater can also be connected to a
controller via its serial or FSK port.
Remote A remote is normally connected to a controller
via its serial or FSK port.
The remote communicates directly with the
master, or with the closest repeater.
Set to Yes if one or more repeaters are present in your 900 MHz radio
network.
Note that this setting is only applicable to the master radio. It is not
displayed for the Repeater and Remote radios.
ENCOM serial radios employ a frequency-hopping method of transmitting
data. The radio's carrier frequency changes periodically according to one
of 64 pseudo-random sequences.
In order for two radios to communicate with each other, they must be
assigned the same hop pattern.
In a network with no repeaters, all radios must be assigned the same
primary hop pattern.
In a network with repeaters, the master and the radios that communicate
directly with it must be assigned the same primary hop pattern.
The radios that communicate directly with a repeater are assigned a
primary hop pattern that matches the repeater's repeater hop pattern.
Refer to the PULSE Link Network Example
assigning primary hop patterns.
This option is only available on repeater radios. It defines the hop pattern
to use between a repeater and the radios that communicate directly with
it.
The repeater's repeater hop pattern must be different than its primary hop
pattern in order to prevent interference between the master-facing and
remote-facing sides of the connection.
