Setting ID
Rotary switch settings only affect Slot 0 and all other slots are sequentially
increased by a value of one after that slot.
The ID is set sequentially starting from a base address. The base address, or
starting address, is set via a 0-7 position rotary switch located on the personality
module. There is a second 0-15 position rotary switch which can be changed to
modify the base address setting.
The default value for both switches is 0. In this default configuration, the device ID
values are as shown.
The 0-7 switch is used to set the
base address which is multiplied
by 16, and the 0-15 switch is
used to set the offset modifier to
the base address. The formula
for setting the ID is: x(16)+y,
where x is the 0-7 switch and y is
the 0-15 switch.
Ex. The 0-7 switch is set to 2, the 0-15 switch is set to 6. This sets the base address
to 38 (2*16=32, +6=38). So Slot 0 ID = 38, Slot 1 ID = 39, Slot 2 ID = 40, Slot 3
ID = 41, etc… up to Slot 9 ID = 47.
The table below provides the Slot 0 Starting (Base) Address Settings.
