Operating Manual: Chapter4 Configuration
Select a Network Address
and assign it to all units
which will be included in the
network.
Use the same Unit Address
on both units for point-to-
point mode. In multipoint
mode, set each Slave and
Repeater to a different Unit
Address.
Valid Unit Addresses are 1
to 65535.

Network Address S104 3
The Network Address defines the communications network to which
individual units can be a part of. By establishing a network under a
common Network Address, the network can be isolated from any other
concurrently operating network. As well, the Network Address provides a
measure of privacy and security. Only those units which are members of the
network will participate in the communications interchange. Valid values
for the Network Address range from 0 to 65535, inclusive.
To enhance privacy and reliability of communications where multiple
networks may operate concurrently in close proximity, it is suggested that an
atypical value be chosen – perhaps something meaningful yet not easily
selected by chance or coincidence.
Default is 1.

Unit Address S105 4
In point-to-point operation, the Unit Address on both the Master and Slave
(or Repeater) units must be the same. In a multipoint system, the Unit
Address uniquely identifies each Slave and Repeater from one another.
Each unit in a multipoint system must have a unique Unit Address ranging
from 1 to 65535. Do not use 0 as a Unit Address, and do not use a Unit
Address more than once within the same Network. This is required because
the Master must be able to acknowledge each unit individually, based on the
Unit Address.

Primary Hopping Pattern S106 5
Secondary Hopping Pattern S206 B
Since the CompactRF
TM
is a frequency-hopping modem, the carrier
frequency changes periodically according to one of 30 pseudo-random
patterns, defined by the Primary and Secondary Hopping Patterns. Valid
entries for each are 0 through 29.
The concept of Primary and Secondary Hopping Patterns was introduced in
the discussion of S Register 101 (Operating Mode).
Using the designations M[a,] Rx[a,b] and Sx[a] where:
- M indicates Master;
- R indicates Repeater;
- S indicates Slave;
- x is the Unit Address;
- a is the primary hopping pattern; and,
- b is the secondary hopping pattern;
