Switch S4 sets the unit address.

When using the 4051 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 control-

ler, the NMS unit address should

be left at the factory default setting

of 1

where Position 1 is Up and all

other positions are Down.

Switch S4 has eight positions used

to create an 8-bit binary code for

an address in the range of 1 to 50.

Switch position S4-1 is the least

significant bit (LSB) and S4-8 is

the most significant bit (MSB). If a

switch is down, its value is 0. If

up, its value is that of the upper lo-

cation. The values are additive. For

example, to set a unit address to 5,

position S4-3 (binary value is 4)

and position S4-1 (binary value is

1) would be set Up for a unit ad-

dress of 5 (4+1). All other posi-

tions would be set Down.
