Addressing the Unit

A unique address must be assigned to each control and
tributary DSU in your network. You can assign an address
within the range of 1 through 255.
NOTE
Do not assign the number 192
as a network address. This
number is reserved as a
broadcast address.
If a DBM is installed, it requires a separate address
which is automatically assigned by the DSU. The address
assigned a DBM is the DSU's address, plus 1 (e.g., if the
DSU's address is 1, the assigned DBM address will be 2).

NOTE
The numbers 191 and 255
cannot be assigned to a DSU
that has a DBM. However,
addresses can be assigned in
any order; they do not have to be
sequential.
It is recommended that only
odd-numbered addresses be
assigned to DSUs so that
even-numbered addresses are
reserved for DBMs . If your
network does not currently
include DBMs, you retain the
flexibility to add them later
without having to reconfigure
your entire network.
