Address Switch S4
Switch S4 sets the unit address. When using the 4001 with a
8100A Site Controller, each element 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 fac-
tory default setting of 1 where Position 1 is Up and all other
positions are Down (see Figure 2-5).
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-
1is the least significant bit (LSB) and S4-8 is the most signifi-
cant 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 S4-3 (binary value
is 4) and position S4-1 (binary value is 1 would be set Up for a
unit address of 5 (4+1). All other positions would be set Down.
Interface Switches S5 and S6
Switches S5 and S6 are slide switches that set the unit to
either RS-232 or V.35. Both switches must be set to the
same selection (that is, RS-232 or V.35).
