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

for a unit address of 5 (4+1). All other

positions would be set
