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.
