Sequential and Numerical Configuration
Decoder addresses don’t necessarily have to be in
sequential order as long as they’re in numerical
order.
It’s okay to skip numbers as long as lower numbers
come first in the sequence.
For example:
• Table 2.1 shows decoders in both sequential
and numerical order.
• Table 2.2 shows decoders out of sequence but
still in numerical order.
• Table 2.3 shows decoders incorrectly out of
numerical order.

NOTE: If decoders were installed out of order,
see “Change a Station’s Decoder Address” on
page 6.
Place Decoder Address Labels
Apply the decoder barcode labels to the appropriate
fields on the Programming Chart that came with
your controller.
a
Carefully peel off the 2-Wire decoder barcode
label.
Remove Address Labels.
B
NOTE: Do not remove the label from the carri-
er still attached to the decoder.
b
Apply the barcode label to an available
row corresponding to a station on the
programming chart.
