Switch S2
Switch S2 sets the unit address. When using the
3021 with an 8100A Site Controller, each ele-
ment in a group must have a unique unit
address. As many as 50 units (with addresses
from 1 to 50) can exist in a group. If the unit is
not connected to a site controller, the NMS unit
address should be left at the factory default set-
ting of 1 where Position 1 is Up and all other
positions are Down.
Switch S2 has eight positions used to create an
8- bit binary code for an address in the range of
1 to 50. Switch position S2 -1 is the least signif-
icant bit (LSB) and S2-8 is the most significant
bit (MSB). If a switch is down, its value is 0. If
up, its value is that of the upper location. The
values are additive. For example, to set a unit
address to 5, position S2-3 (binary value is 4)
and position S2-1 (binary value is 1) would be
set Up for a unit address of 5 (4 + 1). All other
positions would be set Down.
